Hurricane Gustav

September 2, 2008

Tropical Update, Monday September 2, 2008

Here is our update on the current named storms:

Gustav is winding down over land - it will probably be a TD when the NHC comes out with their morning update:

THE RADAR PRESENTATION OF GUSTAV HAS CONTINUED TO DEGRADE THIS EVENING AS THE STORM HAS MOVED INLAND OVER LOUISIANA. RECENT MAXIMUM DOPPLER VELOCITIES FROM THE LAKE CHARLES RADAR HAVE BEEN AROUND 65-70 KT AT ABOUT 4500 FT. THIS EQUATES TO ABOUT 50 KT AT THE SURFACE...THEREFORE GUSTAV IS DOWNGRADED TO A TROPICAL STORM. GUSTAV SHOULD CONTINUE WEAKENING AND IT IS EXPECTED THAT IT WILL BECOME A TROPICAL DEPRESSION ON TUESDAY... AND A REMNANT LOW IN A COUPLE OF DAYS.

Hanna seems to have drifted to the south a bit - it must be soaking the Turks & Caicos islands. It is also closer to Cuba and Hispaniola which can not be good news for those islands that are already drenched. Max sustained winds are 70 miles an hour. The NHC still has this heading north west at some point soon. Only time will tell.

CONVENTIONAL AND PASSIVE MICROWAVE SATELLITE IMAGERY INDICATE HANNA HAS MOVED SOUTHWARD OVER THE PAST 6 HOURS WHILE MAINTAINING A PRONOUNCED EYE FEATURE IN A 02/203Z AMSU OVERPASS. SATELLITE INTENSITY ESTIMATES ARE T4.0/65 KT AND T4.5/77 KT FROM TAFB AND SAB...RESPECTIVELY. THEREFORE...THE INITIAL INTENSITY REMAINS UNCHANGED AT 70 KT FOR THIS ADVISORY.

Ike is making a brisk move westward:

THE STRUCTURE OF IKE HAS NOT CHANGED SIGNIFICANTLY THIS EVENING WITH SUBSTANTIAL CONVECTIVE BANDING EMBEDDED IN A LARGE SURFACE CIRCULATION. THE DVORAK CLASSIFICATIONS FROM TAFB AND SAB REMAIN 3.0 OR 45 KT...WHICH IS THE CURRENT INTENSITY.

AN AMSU PASS AT 0020Z PROVIDED SOME CONFIDENCE IN ESTIMATING A TRACK AT 280 DEGREES AT 13 KT. THE TROPICAL STORM WILL BE MOVING BRISKLY OFF TOWARD THE WEST OR WEST-NORTHWEST UNDER THE INFLUENCE OF A DEEP LAYERED SUBTROPICAL RIDGE TO ITS NORTH.

And... TD 10 (!) has formed way out in the open Atlantic:

ROPICAL DEPRESSION TEN FORECAST/ADVISORY NUMBER 1 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL102008 0900 UTC TUE SEP 02 2008

TROPICAL DEPRESSION CENTER LOCATED NEAR 12.4N 23.9W AT 02/0900Z POSITION ACCURATE WITHIN 30 NM

PRESENT MOVEMENT TOWARD THE WEST OR 275 DEGREES AT 14 KT

ESTIMATED MINIMUM CENTRAL PRESSURE 1007 MB MAX SUSTAINED WINDS 30 KT WITH GUSTS TO 40 KT. 12 FT SEAS.. 40NE 0SE 0SW 40NW. WINDS AND SEAS VARY GREATLY IN EACH QUADRANT. RADII IN NAUTICAL MILES ARE THE LARGEST RADII EXPECTED ANYWHERE IN THAT QUADRANT.

You can find all the latest NHC updates on these systems in the left hand navigation on the Hurricane blog home page.

In short - the Turks & Caicos, the Bahamas, Cuba, Hispaniola, and the US east coast from Florida to at least South Carolina need to be on alert for these next couple of storms - Hanna and Ike. TD 10 is a little too far out yet but the initial path looks to take it towards Ike's path if not a little more to the north. Again though, it is early and you never know. The NHC didn't have the jog to the south for Gustav that took it to the south coast of Jamaica, and they also had not imagine Hanna stalling around the T&C for a couple of days. The models do what they can - but every scenario is a new one. The only thing we know for sure is that the hurricane season is in full swing. Stay safe.

HURRICANE GUSTAV DISCUSSION NUMBER 32

THE CENTER OF GUSTAV MADE LANDFALL ALONG THE LOUISIANA COAST NEAR COCODRIE ABOUT 1430 UTC. DURING THE PAST FEW HOURS...THE EYE BECAME BETTER DEFINED ON RADAR. HOWEVER...WIND DATA FROM AIR FORCE RESERVE AND NOAA AIRCRAFT ALONG WITH DOPPLER RADAR WINDS SUGGESTS THAT GUSTAV WEAKENED TO A CATEGORY TWO HURRICANE BEFORE LANDFALL. THE INITIAL INTENSITY OF 95 KT IS BASED ON THE AIRCRAFT DATA...AND THIS MIGHT BE A LITTLE GENEROUS.

Of course they may change that when they crunch the data later...

Hurricane Gustav downgraded to category two

So the NHC did downgrade the storm to a Category 2 before it made land fall. That is a huge difference - it could have been much worse. From the Guardian:

Hurricane Gustav weakened to a category two storm as it continued on its path towards the largely deserted coast of Louisiana, with predictions that New Orleans could avoid its full force when it reaches the city later today.

The National Hurricane Centre said Gustav had weakened to a category two hurricane by 8am (2pm BST) -- a storm with winds of 155-180kph (95-110 mph), which can generate a storm surge of around 2-3 metres.

Hurricane Gustav hits US coast

From AFP, it seems like Gustav did lose a little steam before land fall:

Despite a slight weakening of Gustav as it neared the coast, forecasters warned of an "extremely dangerous" surge of up to 4.2 meters (14 feet), not as high as earlier predicted but still enough to worry locals after Hurricane Katrina burst New Orleans' levees in 2005 and flooded the city for days.

Gustav update, September 1, 2008

At about 9 AM EST Gustav was just a bit off the coast of Lousiana: HurTrack1.9.1.08.gif

Gustav does not seem to be strengthening at all, and will now degrade as it goes over land. It looks like the Gulf Coast got a little bit of break right now (relatively - this is still a major storm) - Gustav is definitely not as strong as it once was and could have been:

OBSERVATIONS FROM AN AIR FORCE HURRICANE HUNTER AIRCRAFT INDICATE THAT GUSTAV IS NOT STRENGTHENING. THE CENTRAL PRESSURE HAS RISEN SLIGHTLY AND...BASED ON RECENT FLIGHT-LEVEL AND SFMR SURFACE WIND MEASUREMENTS...100 KT IS A GENEROUS ESTIMATE FOR THE CURRENT INTENSITY. WSR-88D RADAR IMAGES SHOW THAT THE EYE WALL IS OPEN OVER THE SOUTHERN SEMICIRCLE...PERHAPS DUE TO THE MID- TO UPPER-LEVEL DRY AIR INTRUSION FROM THE SOUTH THAT WAS DISCUSSED EARLIER. IN FACT...THE AIR FORCE HURRICANE HUNTERS DID NOT REPORT AN EYEWALL. WATER VAPOR IMAGERY ALSO SUGGESTS A DRY INTRUSION AND A RESTRICTION OF THE UPPER-LEVEL OUTFLOW OVER THE SOUTHERN PORTION OF THE HURRICANE. ALSO THE CLOUD PATTERN HAS BECOME A BIT MORE RAGGED ON GEOSTATIONARY SATELLITE PICTURES. BASED ON CURRENT TRENDS AND THE PROXIMITY TO THE COAST...NO SIGNIFICANT INCREASE IN STRENGTH APPEARS LIKELY PRIOR TO LANDFALL.

Carnival cruise extended by Gustav

If you were looking forward to seeing friends or family from this ship, you'll have to wait a couple of more days:

A five-day voyage on a cruise ship that was scheduled to dock in Galveston on Monday has been extended two days because of Hurricane Gustav, Carnival Cruise Lines announced Sunday.

The Carnival Ecstasy, which visited Progreso in the Mexican state of Yucatan, will "remain at sea at a safe distance away from the storm" and will return to Galveston on Wednesday, the cruise line said in a written statement.

HURRICANE GUSTAV DISCUSSION NUMBER 29

HURRICANE GUSTAV DISCUSSION NUMBER 29 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072008 500 PM EDT SUN AUG 31 2008

VISIBLE SATELLITE IMAGERY DURING THE PAST COUPLE OF HOURS SUGGESTS THAT GUSTAV IS GETTING A LITTLE BETTER ORGANIZED...WITH A HINT OF AN EYE RETURNING. ADDITIONALLY...THE CENTRAL PRESSURE REPORTED BY AN AIR FORCE RESERVE HURRICANE HUNTER HAS FALLEN TO 957 MB. ON THE OTHER HAND...THE MAXIMUM 700 MB FLIGHT-LEVEL WINDS WERE 105 KT WHILE THE MAXIMUM SFMR WINDS WERE 93 KT. ALSO...THE CONVECTION...WHILE VIGOROUS...IS STILL RATHER ASYMMETRIC AROUND THE 30 NM WIDE EYE THAT IS OPEN TO THE SE. BASED ON THE AIRCRAFT DATA...THE INITIAL INTENSITY IS LOWERED TO 100 KT.

THE INITIAL MOTION IS WOBBLING BETWEEN 315 AND 320 DEGREES AT 15-16 KT...WITH 320/16 BEING THE ADVISORY MOTION. THERE IS NO CHANGE IN THE TRACK FORECAST PHILOSOPHY...WITH A MID-LEVEL RIDGE OVER THE EASTERN UNITED STATES EXPECTED TO STEER GUSTAV NORTHWESTWARD INTO THE NORTHERN GULF COAST. THE NEW GUIDANCE RUNS...MOST NOTABLY THE HWRF...SHOW A SLIGHT LEFT TURN AFTER 12 HR WITH A LEFTWARD SHIFT IN THE LANDFALL POINT ON THE LOUISIANA COAST. THE NEW FORECAST TRACK IS SHIFTED SLIGHTLY TO THE LEFT OF THE PREVIOUS TRACK...AND SINCE IT LIES NEAR THE EASTERN EDGE OF THE GUIDANCE ENVELOPE SOME ADDITIONAL SMALL SHIFTS MAY BE NECESSARY LATER. AFTER 48-72 HR...THERE REMAINS MAJOR DISAGREEMENT BETWEEN THE DYNAMICAL MODELS ON WHETHER GUSTAV WILL RECURVE INTO THE WESTERLIES...SHEAR APART AND STALL OVER LOUISIANA OR TEXAS...OR TURN SOUTHWESTWARD. THE FORECAST TRACK AFTER 72 HR FOLLOWS THE SHEAR-APART-AND-STALL SCENARIO...CALLING FOR GUSTAV TO MOVE SLOWLY WESTWARD AS IT WEAKENS OVER LAND.

ANALYSES FROM CIMSS AT THE UNIVERSITY OF WISCONSIN INDICATE THAT GUSTAV REMAINS IN ABOUT 20 KT OF SOUTHERLY SHEAR...WITH A LOT OF MID/UPPER-LEVEL DRY AIR SEEN IN WATER VAPOR IMAGERY SOUTH AND WEST OF THE CYCLONE. THE EYE HAS MOVED NORTHWEST OF THE DEEP WARM WATER OF THE LOOP CURRENT...AND THAT COMBINED WITH THE LIKELIHOOD OF CONTINUED SHEAR REDUCES THE CHANCES OF SIGNIFICANT INTENSIFICATION. THE SHIPS MODEL FORECASTS NO STRENGTHENING BEFORE LANDFALL...WHILE THE GFDL AND HWRF FORECAST ABOUT 10 KT OF STRENGTHENING. GIVEN THE FALLING PRESSURES AND THE COLD CONVECTION...THE INTENSITY FORECAST CALLS FOR WINDS TO INCREASE TO 110 KT BEFORE LANDFALL...WITH GUSTAV MAKING LANDFALL AS A MAJOR HURRICANE. GUSTAV SHOULD WEAKEN AFTER LANDFALL AND BECOME A REMNANT LOW IN ABOUT 120 HR.

"Officials measured gusts of 212 mph"

Wow - not much is usually left at that point (from the NY Times):

Officials measured gusts of 212 mph (340 kph) in the western town of Paso Real del San Diego -- a new national record for maximum wind speed in a country often hit by major hurricanes, said Miguel Angel Hernandez of the Cuban Institute of Meteorology.

A Cuban television reporter on the Isla de la Juventud said the storm had felt like ''the blast wave from a bomb.''

HURRICANE GUSTAV DISCUSSION NUMBER 25

THE CENTER OF THE EYE OF GUSTAV HAD BEEN HUGGING THE EASTERN COAST OF THE ISLE OF YOUTH EARLIER THIS AFTERNOON...BUT IS NOW OVER WATER IN BETWEEN THAT ISLAND AND MAINLAND WESTERN CUBA. AIRCRAFT FIXES CONTINUE TO COME IN JUST ABOUT RIGHT ALONG THE PREVIOUS FORECAST TRACK. VISIBLE SATELLITE IMAGERY SUGGESTS GUSTAV HAS BEEN WOBBLING SLIGHTLY...BUT THE INITIAL MOTION APPEARS RELATIVELY WELL-ESTABLISHED AT 315/13...WITH STEERING PROVIDED BY A MID-LEVEL RIDGE OVER THE WESTERN ATLANTIC. THE VARIOUS MODELS HAVE COME INTO BETTER AGREEMENT ON A TRACK INTO THE NORTH-CENTRAL GULF COAST WITHIN THE NEXT COUPLE OF DAYS. THE HWRF...UKMET...AND NOGAPS...WHICH HAD PREVIOUSLY FORECAST A STALL JUST OFFSHORE...HAVE COME INTO THE FOLD WITH THE GFS...GFDL...AND ECMWF...RESULTING IN A CONSENSUS TRACK THAT FALLS VERY CLOSE TO THE PATH OF THE PREVIOUS ADVISORY. THIS AGREEMENT HAS ALSO RESULTED...HOWEVER...IN A CONSENSUS TRACK THAT REACHES THE COAST A LITTLE FASTER. THE NEW OFFICIAL TRACK IS ALMOST EXACTLY ALONG THE PATH OF THE PREVIOUS ADVISORY...BUT MAINTAINS THE CURRENT HEADING AND SPEED ALL THE WAY TO THE COAST...ARRIVING THERE A LITTLE SOONER THAN BEFORE. WHILE THERE IS INCREASED CONFIDENCE IN BOTH THE PATH AND SPEED OF THE TRACK THROUGH ABOUT 48 HOURS...THE MODEL SPREAD IS STILL SUFFICIENTLY LARGE TO SERVE AS A REMINDER THAT WE CANNOT SPECIFY EXACTLY WHERE OR WHEN THE CENTER OF GUSTAV WILL MAKE FINAL LANDFALL. AFTER LANDFALL...ALL OF THE MODELS RESPOND TO WEAKENING STEERING CURRENTS...WELL TO THE SOUTHWEST OF THE HIGH OVER THE NORTHEASTERN UNITED STATES...BY FORECASTING A DRAMATIC SLOWING OF THE FORWARD SPEED OVER LOUISIANA AND EASTERN TEXAS...AND THE OFFICIAL FORECAST AGAIN FOLLOWS SUIT.

Gustav update

Gustav is now a category 4 and could become a category 5 hurricane on the Saffir-Simpson Hurricane Scale. This already deadly storm is now at a much higher danger level than it was when it came through Hispaniola and the Cayman Islands. Western Cuba, and eventually the Gulf Coast need to be prepared for the severity of Gustav.

Gustav swells to dangerous Cat 3 storm off Cuba

From the AP:

GEORGE TOWN, Cayman Islands (AP) -- Gustav swelled to a fearsome Category 3 hurricane with winds of 120 mph as it shrieked toward the heartland of Cuba's cigar industry Saturday on a track to hit the U.S. Gulf Coast three years after Hurricane Katrina.

The U.S. National Hurricane Center in Miami called the storm, which has already killed 71 people in the Caribbean, ''dangerous'' and said it had become the second major hurricane of the Atlantic season, following Bertha in July.

Cuban state television announced that all buses and trains to and from Havana were suspended, as was ferry service to the Isla de Juventud, the outlying Cuban island next in Gustav's path.

Authorities announced they were prepared to ''protect'' the 20,000 tourists in Matanzas province, which includes the famous beach resort of Varadero.

Gustav rolled over the Cayman Islands Friday with fierce winds that tore down trees and power lines.

At first light Saturday, Associated Press journalists found that Grand Cayman island was spared major damage. Big surging waves pounded at the island, but there was little flooding, and wind damage was limited because islanders had removed signs and other items that could blow away.

Gustav swells to dangerous Cat 3 storm off Cuba

From the AP:

GEORGE TOWN, Cayman Islands (AP) -- Gustav swelled to a fearsome Category 3 hurricane early Saturday with winds of 115 mph as it approached western Cuba on a track to hit the U.S. Gulf Coast three years after Hurricane Katrina.

The U.S. National Hurricane Center in Miami called the storm "dangerous" and said it had reached the status of a major hurricane, the second one of this Atlantic season after Bertha in July.

Gustav, which killed 71 people in the Caribbean, rolled over the Cayman Islands Friday with fierce winds that tore down trees and power lines. It was expected to cross Cuba's cigar country Saturday and head into the Gulf of Mexico by Sunday.

Gustav first struck Cayman Brac and Little Cayman, the smaller easternmost "Sister Islands" in the chain. Storm surge and heavy rains flooded the streets.

A hurricane again, Gustav plows toward Caymans

From the AP:

GEORGE TOWN, Cayman Islands (AP) -- Gustav became a hurricane again on Friday as it plowed toward Cayman Islands resorts, the start of a buildup that could take it to the U.S. Gulf Coast as a fearsome Category-3 storm three years after Hurricane Katrina.

Gustav, which killed 71 people in the Caribbean, was expected to swirl through the Cayman Islands, a tiny offshore tax haven studded with resorts and cruise-ship souvenir shops, before crossing Cuba's cigar country and heading into the Gulf of Mexico by Sunday.

Well-heeled tourists fled Cayman hotels by air, while Katrina victims in Mississippi still living in emergency cottages and trailers were told to evacuate beginning this weekend.

Hotels on the Cayman Islands asked guests to leave, then after the airport closed prepared to shelter those who remained. Chris Smith, of Frederick, Maryland, said his hotel handed out wrist bands marked with guests' names and room numbers so that "if something happens they can quickly identify us."

"That was a little bit sobering," he said, standing outside the hotel with his luggage.

Gustav Grows Stronger, Aims for Cayman Islands, Western Cuba

From the VOA:

U.S. forecasters say Gustav has returned to hurricane strength as the storm crosses the Caribbean towards the Gulf of Mexico.

Gustav was expected to pass near or over the Cayman Islands later Friday and western Cuba on Saturday. Forecasters say the storm that has already caused at least 72 deaths could produce more than half a meter of rain in some areas.

The Miami-based National Hurricane Center said Gustav had sustained winds of up to 120 kilometers per hour mid-afternoon Friday. The center says the Category one storm is likely to grow into a major hurricane over the warm waters of the Gulf of Mexico.

TROPICAL STORM GUSTAV DISCUSSION NUMBER 18

Gustav is looking tricky - the track could still go almost anywhere - and the NHC is expecting to strengthen rapidly into a hurricane:

TROPICAL STORM GUSTAV DISCUSSION NUMBER 18 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL072008 500 AM EDT FRI AUG 29 2008

SATELLITE IMAGES SHOW THAT GUSTAV HAS AN EXPANDING CLOUD SHIELD AND IMPRESSIVE BANDING FEATURES. AN AIR FORCE RECONNAISSANCE PLANE THAT HAS BEEN SAMPLING THE STORM'S CIRCULATION FOUND THAT THE SIZE OF GUSTAV HAS SIGNIFICANTLY INCREASED. ALTHOUGH THEY HAVE BEEN UNABLE TO SAMPLE THE CENTER...PEAK FLIGHT LEVEL WINDS OF 52 KT WERE OBSERVED...ALONG WITH SIMILAR VALUES FOR THE SFMR. THE INITIAL INTENSITY REMAINS 55 KT.

THE BEST ESTIMATE OF INITIAL MOTION IS 285/7. THERE IS A COMPLICATED EVOLUTION TO THE STEERING CURRENTS AROUND GUSTAV DURING THE FORECAST PERIOD. THE MID-LEVEL RIDGE OVER FLORIDA THAT HAS BEEN STEERING THE STORM WESTWARD IS FORECAST TO WEAKEN TODAY. THE BERMUDA HIGH IS THEN EXPECTED TO BUILD IN FROM THE WESTERN ATLANTIC AND CAUSE GUSTAV TO MOVE MORE TOWARD THE NORTHWEST OVER THE WEEKEND. ONE BIG QUESTION IS THE EVOLUTION OF A MID- TO UPPER- LEVEL LOW OVER THE SOUTHEASTERN UNITED STATES. SOME OF THE MODELS...SUCH AS THE GFS/GFDL/HWRF...ARE SHOWING THIS LOW CREATING ENOUGH OF A WEAKNESS IN THE BERMUDA HIGH TO ALLOW A MOTION MORE TOWARD THE NORTH-NORTHWEST AS THE SYSTEM CROSSES CUBA. IT WOULD NOT BE SURPRISING IF THAT TRACK BRIEFLY OCCURRED...BUT IN THE LONGER-TERM...A HIGH OVER THE OHIO VALLEY IS EXPECTED TO CAUSE GUSTAV TO GRADUALLY BEND TO THE LEFT. HOWEVER...THERE IS A LARGE UNCERTAINTY IN THE TIMING AND SHARPNESS OF THE BEND. THE UKMET AND GFS HAVE HAD LARGE CHANGES TO THEIR FORECAST FROM THE PREVIOUS RUNS...AND GIVEN THE INCREASING MODEL SPREAD...WE'VE OPTED TO KEEP THE FORECAST SIMILAR TO THE PREVIOUS ONE. HOPEFULLY A G-IV MISSION LATER TODAY WILL HELP RESOLVE SOME OF THESE DIFFERENCES.

AFTER THE STORM MOVES AWAY FROM JAMAICA...SIGNIFICANT INTENSIFICATION IS POSSIBLE. VERTICAL WIND SHEAR IS FORECAST TO BE VERY LIGHT DURING THE NEXT COUPLE OF DAYS...AND COMBINED WITH THE DEEP WARM CARIBBEAN WATERS...COULD PRODUCE A STRONG HURRICANE VERY QUICKLY. THE OFFICIAL FORECAST WILL SHOW RAPID INTENSIFICATION BEFORE IT REACHES WESTERN CUBA AND COULD BE CONSERVATIVE AS SOME MODELS SHOW CATEGORY FOUR STRENGTH AT THAT TIME. A LARGE TROUGH CURRENTLY SEEN IN WATER VAPOR IMAGES OVER THE CENTRAL GULF OF MEXICO IS EXPECTED TO MOVE WESTWARD SLOWLY DURING THE NEXT DAY OR TWO. THIS TROUGH MAY IMPART SOME SOUTHWESTERLY SHEAR ON GUSTAV AS IT ENTERS THE CENTRAL GULF OF MEXICO. ALTHOUGH THE FORECAST SHOWS SOME WEAKENING DUE TO THE SHEAR...GUSTAV IS EXPECTED TO BE A LARGE POWERFUL HURRICANE AS IT APPROACHES THE NORTHERN GULF COAST.

TROPICAL STORM GUSTAV DISCUSSION NUMBER 16

Gustav could become a major hurricane:

...DUE TO THE VERY WARM WATERS SOUTH OF CUBA...COMBINED WITH ANTICYCLONIC FLOW ALOFT...IT IS POSSIBLE THAT GUSTAV COULD RAPIDLY INTENSIFY AT SOME POINT WITHIN THE NEXT COUPLE OF DAYS...ALTHOUGH THAT IS NOT EXPLICITLY SHOWN IN THE OFFICIAL FORECAST...

It appears from various news reports that Jamaica is having wind and rain but not getting hit too hard, and currently Gustav is only classified as a tropical storm. It has a long way to go and could lose more steam than expected traveling the length of Jamaica, but if it makes it to the other side a lot of warm water (fuel) will be waiting for it - and the Cayman Islands unfortunately look to be directly in line at the moment.

Tropical Storm Hanna forms as Gustav soaks Jamaica

From McClatchy:

Tropical Storm Gustav closed in on Jamaica Thursday at near-hurricane strength while Tropical Storm Hanna formed in the Atlantic.

Hanna, the eighth named storm of the 2008 hurricane season, is spinning about 1,500 miles east-southeast of Miami with 40 mph winds. Forecasters said Hanna could grow into a hurricane by Labor Day but likely wouldn't threaten the U.S. coast until later next week, if at all.

Meanwhile, Gustav's winds increased to 70 mph from 45 mph overnight as it took a turn toward Jamaica. The center of Gustav was moving over the island's eastern shoreline at 2 p.m., about 40 miles east of Kingston.

51 Haitians die in Hurricane Gustav

Just terrible news from Haiti:

PORT-AU-PRINCE, Haiti (AP) -- Haitian officials are reporting 51 deaths from Gustav, raising the storm's overall toll to 59.

Civil protection department director Marie Alta Jean-Baptiste says the death count increased fivefold on Thursday as news reached officials from remote areas.

At least 25 people were killed near Jacmel, on the country's southern peninsula, where Gustav came ashore Tuesday as a Category 1 hurricane.

Civil protection official Jean-Michel Sabbat says most of those people were killed by landslides and falling trees in the mountains.

Tourists flee as Gustav churns toward Jamaica

From the AP:

KINGSTON, Jamaica (AP) -- Tourists and oil workers fled Thursday as Gustav churned toward Jamaica and the Cayman Islands with winds near hurricane force. Louisiana called a state of emergency and put the National Guard on standby, hoping to avoid the chaos of Hurricane Katrina three years ago.

Gustav moved away from the island of Hispaniola, where it killed 23 people in Haiti and the Dominican Republic, and inched toward Jamaica's low-lying capital, 80 miles (130 kilometers) to the west. Forecasters predicted it would hug Jamaica's southern shore before making a near-direct hit on Grand Cayman.

Even as tourists searched for flights off the islands, officials urged calm. Theresa Foster, one of the owners of the Grand Caymanian Resort, said Gustav didn't look as threatening as Hurricane Ivan, which destroyed 70 percent of Grand Cayman's buildings four years ago.

"Whatever was going to blow away has already blown away," she said.

Tropical Storm Gustav shifts track to the south

From Reuters:

MIAMI (Reuters) - Tropical Storm Gustav shifted course slightly on Thursday morning and moved toward the Jamaica, and forecasters predicted it would be a powerful hurricane by the time it reached the Gulf of Mexico.

"The re-formation of the center has caused a big southward change ... and Gustav is now forecast to pass near the south coast of Jamaica," the U.S. National Hurricane Center said.

While the storm's eventual U.S. landfall could be anywhere from the Florida Panhandle to Texas, one of its likely tracks was west of New Orleans, the southern U.S. city devastated by Hurricane Katrina in 2005.

Gustav was projected to hit the U.S. Gulf Coast around Monday, two days after the third anniversary of Katrina, which killed 1,500 people and caused at least $80 billion in damage in several Gulf Coast states.

The NHC basically lost track of this storm overnight. The shift south is a pretty major move. It just reinforces the fact that you have to be prepared for anything when these storms are within a few hundred miles of your location.
