We won't be monitoring Bertha much anymore unless she someone makes a turn to the south and moves toward the Caribbean again (not likely!). You can follow Bertha at the NHC website: http://www.nhc.noaa.gov/#BERTHA

Once this storm is dead that link won't work but you will be able to use our archives and the NHC archives.

Hurricane Bertha chugs toward Bermuda

Published on July 11, 2008 8:39 AM | Comments

From CNN:

MIAMI, Florida (CNN) -- Hurricane Bertha, a Category 1 storm, was causing large swells and high surf on Bermuda beaches Friday morning as it crept toward the Atlantic island.

Forecasters could not predict how close Bertha's strong winds would come to Bermuda, but a tropical storm watch may be issued there Friday, the National Hurricane Center said.

As of 5 a.m. Friday, Bertha's center was about 350 miles (565 kilometers) south-southeast of Bermuda, moving northwest at near 7 mph (11 kph). The storm's maximum sustained winds had decreased slightly to about 85 mph (140 kph) with higher gusts, forecasters said.

HURRICANE BERTHA DISCUSSION NUMBER 23

Published on July 8, 2008 9:16 PM | Comments

Bertha continues to weaken:

BERTHA'S SATELLITE PRESENTATION CONTINUES TO DEGRADE THIS AFTERNOON AND DVORAK DATA T-NUMBERS HAVE FALLEN DURING THE LAST 6 HOURS. THE INITIAL INTENSITY IS LOWERED TO 75 KT BASED ON AN AVERAGE OF THE VARIOUS INTENSITY ESTIMATES. INDEED...BERTHA'S RAPID INTENSIFICATION YESTERDAY HAS BEEN EQUALED BY ITS RAPID WEAKENING TODAY. SUCH INTENSITY FLUCTUATIONS REMAIN A FORECASTING CHALLENGE AND SERVE AS AN IMPORTANT REMINDER FOR THE UNCERTAINTIES ASSOCIATED WITH INTENSITY FORECASTS. GIVEN THE CURRENT TREND IN SATELLITE IMAGERY...CONTINUED WEAKENING IS POSSIBLE IN THE SHORT-TERM. MOST OF THE INTENSITY MODELS SUGGEST THAT BERTHA MIGHT EVEN REGAIN SOME STRENGTH LATER IN THE FORECAST AS THE SHEAR RELAXES AND THE SSTS INCREASE. DUE TO THE UNCERTAINTY...THE OFFICIAL FORECAST SHOWS SLIGHT WEAKENING IN THE SHORT-TERM WITH LITTLE CHANGE THEREAFTER.

Powerful Hurricane Bertha May Weaken Over Atlantic, Center Says

Published on July 8, 2008 7:17 AM | Comments

This is from Bloomberg:

July 8 (Bloomberg) -- Hurricane Bertha, a "powerful" Category 3 storm, may weaken this week as it passes over the Atlantic away from land, the U.S. National Hurricane Center said.

Bertha's maximum sustained winds were blowing at 120 miles (195 kilometers) an hour, the center said in an advisory posted on its Web site shortly after 4:30 a.m. Miami time. The system strengthened yesterday from a tropical storm.

"Some fluctuations in intensity may occur today, but a gradual weakening trend is expected to begin within the next couple of days," the center said.

So the conditions are not expected to have Bertha continue strengthening at this point.

The good news on Bertha is that current tracking models seem to keep it in the Atlantic, which will make it a concern for shipping but hopefully spare Bermuda.

TROPICAL STORM BERTHA DISCUSSION NUMBER 12

Published on July 5, 2008 11:08 PM | Comments

Sorry for our lack of updates so far on Bertha - we had to help a friend out over the holiday weekend and we also lost our Internet connection for a while. Bertha is now forecast on a much more southerly track, between Bermuda and the Bahamas, and also to become a hurricane. It is still early days for this storm and the NHC is being cautious, but this may become an issue for the Caribbean. We will be watching closely this coming week and trying to post as much news and information as we can for this storm.

TROPICAL STORM BERTHA DISCUSSION NUMBER 12 NWS TPC/NATIONAL HURRICANE CENTER MIAMI FL AL022008 1100 PM EDT SAT JUL 05 2008

LATEST SATELLITE IMAGERY INDICATES THAT BERTHA CONTINUES TO EXHIBIT A CONVECTIVE BURSTING PATTERN WITH THE CENTER CURRENTLY LOCATED NEAR THE SOUTH SIDE OF THE COLDEST CLOUD TOPS. DVORAK INTENSITY ESTIMATES ARE UNCHANGED AND SO IS THE INITIAL INTENSITY...45 KT. BERTHA IS BEGINNING TO ENCOUNTER WARMER WATERS AND THE CYCLONE IS EXPECTED TO REACH THE 27 DEGREE CELSIUS ISOTHERM IN 36-48 HOURS. SINCE THE SHEAR IS EXPECTED TO BE LIGHT DURING THIS PERIOD...SLOW STRENGTHENING IS EXPECTED. THE FORECAST BECOMES MORE UNCERTAIN BEYOND 48 HOURS DUE TO SPREAD IN THE TRACK MODELS AND THE RESULTING DIFFERENCES IN THE ATMOSPHERIC CONDITIONS BERTHA MIGHT EXPERIENCE. A TRACK MORE TOWARDS THE NORTH WOULD ALLOW MORE STRENGTHENING WHILE A TRACK MORE TOWARDS THE WEST WOULD RESULT IN INCREASING VERTICAL SHEAR. SINCE THE OFFICIAL TRACK FORECAST TAKES BERTHA INTO AN AREA WITH MODERATE VERTICAL SHEAR...ARRESTED DEVELOPMENT IS FORECAST BEYOND 72 HOURS. THIS NEW OFFICIAL FORECAST IS CONSISTENT WITH THE PREVIOUS FORECAST BUT SLIGHTLY LOWER THAN THE CONSENSUS OF THE AVAILABLE INTENSITY MODELS.

BERTHA CONTINUES TO MOVE RAPIDLY WESTWARD WITH AN INITIAL MOTION OF 280/18. THIS GENERAL MOTION IS EXPECTED TO CONTINUE FOR THE NEXT 36-48 HOURS COURTESY OF A STRONG RIDGE TO THE NORTH. THEREAFTER... THE CYCLONE BEGINS TO ENCOUNTER A WEAKNESS IN THE SUBTROPICAL RIDGE AND TRACK MODELS DIVERGE SIGNIFICANTLY. IN FACT...THE SPREAD IN THE TRACK MODELS SPAN NEARLY 1300 MILES AT DAY 5 WITH THE UKMET MODEL KEEPING BERTHA HEADED WESTWARD AND THE HWRF TURNING THE CYCLONE NORTHWARD. GIVEN THE UNCERTAINTY...THE OFFICIAL FORECAST IS SIMILAR TO THE PREVIOUS FORECAST AND LIES IN THE MIDDLE OF THE TRACK MODEL ENVELOPE.

IT SHOULD BE NOTED THAT THERE IS LARGER THAN NORMAL UNCERTAINTY IN BOTH THE TRACK AND INTENSITY FORECASTS OF BERTHA. ACCORDINGLY...IT IS MUCH TOO EARLY TO DETERMINE IF BERTHA WILL OR WILL NOT POSE A THREAT TO ANY LAND AREAS.
