Hurricane Joaquin Report

Published on July 2, 2016 12:05 PM | Comments

Hurricane Joaquin 2015

Joaquin was a category 4 hurricane (on the Saffir-Simpson Hurricane Wind Scale) whose strong winds and storm surge devastated Crooked Island, Acklins, Long Island, Rum Cay, and San Salvador in the central and southeastern Bahamas. Joaquin took the lives of 34 people--all at sea--including the 33 crewmembers of the cargo ship El Faro, which sunk during the storm northeast of Crooked Island. Joaquin is the strongest October hurricane known to have affected the Bahamas since 1866 and the strongest Atlantic hurricane of non-tropical origin in the satellite era.

There is an excellent report on Joaquin available from the NHC (PDF).

Tropical Storm Ana

Ana originated from a non-tropical low and made landfall along the northeastern coast of South Carolina, causing minor wind damage, some beach erosion, and one direct death in North Carolina. More here from the NHC.

It sounds as if the Bahamas are really taking a beating. Joaquin is currently a major hurricane and just seems to be parked over the island chain. The Bahamas webcams don't look that bad at the moment (10 a.m. ET, Friday, October 2nd) but that is probably due to the location. The eye seems to be over Long Island/Great Exuma - hoping that all is well there.

Hurricane Joaquin

Published on September 30, 2015 10:15 PM | Comments

We weren't on top of Joaquin at first - but now that it looks to be parked over the Bahamas and affecting the Caribbean region we'll try to keep more up to date. This is a strange one - popped up in an unusual spot, and has the forecasters quite perplexed as to where it eventually heads.

HURRICANE JOAQUIN DISCUSSION NUMBER 12
NWS NATIONAL HURRICANE CENTER MIAMI FL AL112015
500 PM EDT WED SEP 30 2015

There has been little change in the organization of Joaquin during
the past several hours. While the hurricane continues to produce
cloud tops colder than -80C in the eyewall, the eye has not become
better defined since the last advisory. Satellite intensity
estimates are 77 kt from both TAFB and SAB, so the advisory
intensity is now 75 kt.

The initial motion is 225/7. The shortwave ridge causing this
motion is expected to weaken during the next 24-48 hours as a strong
deep-layer trough develops over the southeastern United States.
Thus, a generally southwestward motion is expected for the next 36
hours or so, followed by a turn toward the north as the trough
becomes the dominant steering mechanism. There is an increased
disagreement between the GFS, UKMET, Canadian, and NAVGEM models
versus the ECMWF since the last advisory. The ECMWF has continued
its forecast of showing a northeastward motion after 72 hours,
taking Joaquin just west of Bermuda and out to sea. The other
models have all shifted their forecasts to the left and now
call for landfall in the Carolinas and the mid-Atlantic states,
followed by merger with the baroclinic trough. Given the shift in
the non-ECMWF models, a major westward adjustment has been made to
the forecast track at 96 and 120 hours, bringing the center of
Joaquin near or over portions of the mid-Atlantic states. Due to
the use of the ECMWF in the consensus models, the new track lies
near the various consensus models. However, it lies well to the
east of the GFS and the other similar models. The NOAA G-IV jet is
currently flying a synoptic surveillance mission, which, along with
special rawinsonde launches, hopefully will reduce the spread of the
guidance.

There is little change to the intensity forecast philosophy since
the last advisory. Joaquin is expected to remain in an environment
of moderate northeasterly vertical shear for the next 24-36 hours,
possibly including strong winds seen at 400 mb in recent dropsondes
from the G-IV aircraft. However, since it has been steadily
strengthening in such an environment, there is no obvious reason to
think it will stop doing so. After 36 hours, the hurricane is
likely to move into an area of divergent southerly upper-level winds
associated with the eastern U. S. trough. While there is
uncertainty as to how much shear should occur, it is expected that
additional intensification could occur through at least 48 hours.
Based on this, the intensity forecast calls for Joaquin to peak as a
major hurricane in 48-72 hours, and it is possible it could be
stronger than currently forecast. After 72 hours, increasing shear,
cold air intrusion, and land interaction should cause weakening and
the start of extratropical transition.


KEY MESSAGES:

1. Preparations to protect life and property within the warning
areas in the Bahamas should be rushed to completion.

2. A significant adjustment to the forecast has been made this
afternoon, and this shows an increased threat to the mid-Atlantic
states and the Carolinas. However, confidence in the details of the
forecast after 72 hours remains low, since we have one normally
excellent model that keeps Joaquin far away from the United States
east coast. The range of possible outcomes is still large, and
includes the possibility of a major hurricane landfall in the
Carolinas.

3. Every effort is being made to provide the forecast models with
as much data as possible. The NOAA G-IV jet has begun a series of
missions in the storm environment, and the National Weather Service
is launching extra balloon soundings.

4. Because landfall, if it occurs, is still more than three days
away, it is too early to talk about specific wind, rain, or surge
impacts from Joaquin in the United States. Even if Joaquin stays
well out to sea, strong onshore winds will create minor to moderate
coastal flooding along the coasts of the mid-Atlantic and
northeastern states through the weekend.

5. A hurricane watch for a portion of the U.S. coast could be
required as early as Thursday evening.

6. Many areas of the eastern U.S. are currently experiencing heavy
rains and gusty winds associated with a frontal system. This
inclement weather is expected to continue over the next few days,
which could complicate preparations for Joaquin should it head
toward the coast, and greatly exacerbate the impacts from the
hurricane. Heavy rains are likely to continue over these areas
even if the center of Joaquin stays out to sea.

Tropical Storm Erika Begins

Published on August 25, 2015 8:12 PM | Comments

Well Danny thankfully ran out of steam and produced much needed rain - but now Erika is following right behind. Erika looks to be gearing up a bit and need watching -

TROPICAL STORM ERIKA DISCUSSION NUMBER 4
NWS NATIONAL HURRICANE CENTER MIAMI FL AL052015
500 PM AST TUE AUG 25 2015

After becoming quite disorganized in appearance earlier today,
Erika has made a bit of a comeback with increased deep convection
near and to the south of the center. Data from the Air Force
Hurricane Hunters indicate that the intensity is near 35 kt and
this is consistent with Dvorak estimates from both TAFB and SAB.
Erika has limited upper-level outflow over the northern semicircle
of the circulation, and microwave data suggest that the cyclone has
been ingesting some dry mid-level air. As in the previous
forecast, there is considerable uncertainty as to the future
intensity of this tropical cyclone. The SHIPS guidance indicates
increasing west-northwesterly shear over the next few days, and the
GFS and ECMWF global models do not strengthen the system during the
forecast period. The HWRF and GFDL models do show strengthening,
however, but along a track to the right of most of the guidance.
The official intensity forecast has been reduced a bit from the
previous one and is close to the model consensus.

A center fix from the aircraft indicates that the motion continues
to be near 280/17. A mid-level subtropical ridge to the north of
Erika should steer the system on a west-northwestward track for the
next several days. Late in the forecast period, there is
significant spread in the models, with those models that depict a
weaker system being farther south and west and those having a
stronger cyclone farther to the north and east. The official track
forecast has been adjusted a little to the left of the previous one
and is in line with the latest dynamical model consensus.

Some of the tropical storm watches for the islands of the
northeastern Caribbean may need to be changed to warnings on the
next advisory package.
