HURRICANE CENTER: Eta Prepares To Strike Florida Again

Tropical Storm Eta

Flash Flooding Remains Possible In South Florida Where Heavy Rains Expected. Florida West Coast Under Watches, Warnings.

BOCA RATON, FL (BocaNewsNow.com) — Tropical Storm Eta is preparing to strike Florida yet again, this time on the West Coast. But South Florida isn’t immune. The National Hurricane Center is warning South Florida of heavy rain and notes “additional flash and urban flooding will be possible in South Florida on Wednesday, especially across previously inundated areas, and across portions of West Florida through Friday.”

Here’s the early morning advisory from the National Hurricane Center.


A Hurricane Watch has been issued for the west coast of Florida
from Anna Maria Island to Yankeetown.

SUMMARY OF WATCHES AND WARNINGS IN EFFECT:

A Hurricane Watch is in effect for...
* Anna Maria Island to Yankeetown

A Tropical Storm Warning is in effect for...
* Dry Tortugas
* Bonita Beach to Suwannee River Florida

A Storm Surge Watch is in effect for...
* Bonita Beach to Steinhatchee River Florida, including Tampa Bay
and Charlotte Harbor

A Tropical Storm Watch is in effect for...
* The Cuban provinces of La Habana, Artemisa, Mayabeque, Pinar del
Rio, and the Isle of Youth
* North of the Suwannee River to Aucilla River Florida

A Hurricane Watch means that hurricane conditions are possible
within the watch area, in this case within 24 hours.

A Tropical Storm Warning means that tropical storm conditions are
expected somewhere within the warning area, in this case within 24
hours.

Eta has become better organized over the past few hours, with a 
better-defined eye feature on the Key West radar.  Satellite 
pictures also show a more symmetric presentation and a large 
cluster of deep convection near the center.  Radar data has shown 
increasing wind speeds in the mid-levels, which supports 
conservatively raising the initial wind speed to 60 kt.  The 
current position is southwest of the eye feature on radar, assuming 
some shear remains, but a NOAA Hurricane Hunter aircraft is 
scheduled to be in the storm in a few hours to acquire better data 
on both the initial position and intensity.

It appears that the center of Eta has re-formed to the north- 
northeast tonight, so an initial motion is hard to determine, 
but is estimated to be northward at about 10 kt.  Remarkably, model 
guidance has become well clustered just east of the previous 
forecast track as it seems apparent that Eta will now recurve 
around the ridge toward the Florida Big Bend region and out into 
the western Atlantic Ocean.  The biggest change is that the models 
are faster than before, and the official forecast follows that 
lead, along with a small eastward forecast adjustment, near or just 
east of the model consensus.

Further strengthening is possible today while the shear remains 
low-to-moderate.  However, all of the models do show increasing 
shear by tonight, and the NHC forecast continues to call for 
weakening of Eta as it approaches the west coast of Florida.  
However, it would take only a small forecast error to allow Eta to 
come ashore as a hurricane, and hence a Hurricane Watch has been 
issued this morning.  Rapid weakening is anticipated once Eta makes 
landfall, and strong shear should prevent any regeneration over the 
western Atlantic Ocean. The new forecast is a little higher than 
the previous advisory, mostly due to current trends, and is closer 
to the more bullish HMON and HWRF models.

Key Messages:

1. Life-threatening storm surge is possible early Thursday along 
portions of the Florida Gulf Coast from Bonita Beach to 
Steinhatchee River, including Tampa Bay and Charlotte Harbor. 
Residents in this area should follow any advice given by local 
officials.

2. Hurricane-force winds are possible along portions of the west 
coast of Florida from Anna Maria Island to Yankeetown by early 
Thursday. Tropical-storm-force winds are expected by late Wednesday 
along portions of the Florida Gulf Coast from Bonita Beach to 
Suwanee River, and are possible Thursday from Suwannee River to 
Aucilla River. Interests elsewhere along the Florida Gulf Coast 
should monitor the progress of Eta, as additional watches and 
warnings may be needed today.

3. Heavy rainfall from Eta will continue across western Cuba and 
South Florida and spread northward across portions of West and North 
Florida Wednesday through Friday. Additional flash and urban 
flooding will be possible in South Florida on Wednesday, especially 
across previously inundated areas, and across portions of West 
Florida through Friday.
