Forecasters: Storm Is Turning, Florida Is In Cone Of Uncertainty

UPDATE: For the Wednesday morning (November 4, 2020) update, click here.

BOCA RATON, FL (BocaNewsNow.com) — The National Hurricane Center says Hurricane Eta is now forecast turn to the northwest and is on a path that could lead to a South Florida hit on Sunday. If it happens, Eta will most likely be a tropical storm at the time of impact. There is still significant uncertainty, but watching this storm is a good idea.

Here is the latest from the National Hurricane Center as of very late afternoon on Tuesday, November 3, 2020:



After meandering just offshore of the coast of northeastern
Nicaragua this morning, the eye of Eta began moving westward and is
currently making landfall along the coast of Nicaragua about 15 n 
mi south of Puerto Cabezas.  Visible satellite imagery has shown 
that the eye of Eta became larger as the hurricane completed an 
eyewall replacement.  A blend of the earlier aircraft data and 
recent subjective and objective satellite intensity estimates 
yields an initial intensity of 120 kt. Eta remains an extremely 
dangerous category 4 hurricane, and is likely producing a very high 
storm surge and catastrophic damage.  In addition, the slow-moving 
system is likely to produce torrential rains and inland flooding 
that will continue to be an extremely serious threat over the next 
couple of days.

Once the eyewall is fully onshore, rapid weakening should begin,
and Eta is forecast to weaken to a tropical storm by early
Wednesday, and become a tropical depression Wednesday night.
Although it appears unlikely that the surface circulation will
remain intact while Eta moves over Central America, most of the
global model guidance indicates that the low-level vorticity center
will emerge over the northwestern Caribbean Sea within 60-72 hours.
At that time, the system is forecast to interact with an
upper-level trough over the northern Gulf of Mexico, and 
re-development later in the period appears likely with some 
strengthening by days 4 and 5.  Due the interaction with the 
upper-level trough, the system is likely to have a more hybrid or 
subtropical structure late in the period. 

Eta appears to be moving westward at about 4 kt.  A ridge to the
north of the hurricane should steer the system westward to west-
northwestward at a faster forward speed over the next couple of
days.  By late in the week, Eta or its remnants should turn
northward, and then northeastward around the southeastern portion
of the aforementioned trough.  Although the 12z GFS and ECMWF
models are in general agreement on the overall forecast scenario, 
there are large differences in how fast Eta accelerates 
northeastward.  The NHC track forecast is near the HFIP corrected 
consensus model which lies between the faster GFS and slower ECMWF 
solutions. There is still significant spread among the various 
global models and the ensembles, which results in a higher than 
normal level of uncertainty regarding the details of the track and 
intensity forecast later in the period.

Key Messages:

1. Catastrophic wind damage is expected during the next few hours
as Eta's eyewall moves onshore along the northeastern coast of
Nicaragua.

2. A catastrophic and life-threatening storm surge, along with
destructive waves, are expected along portions of the northeastern
coast of Nicaragua near and to the north of where the center has
crossed the coast.  Water levels could reach as high as 14 to 21
feet above normal tide levels in some parts of the hurricane
warning area.

3. Through Friday evening, heavy rainfall from Eta will lead to
catastrophic, life-threatening flash flooding and river flooding
across portions of Central America, along with landslides in areas
of higher terrain.  Flash and river flooding is also possible across
Jamaica, southeast Mexico, El Salvador, southern Haiti, and the
Cayman Islands.

4. Eta is forecast to regain tropical storm strength as it moves
across portions of Cuba and approaches southern Florida this
weekend.  While it is too soon to determine the exact timing,
magnitude, and location of possible impacts from wind and rainfall,
interests in Cuba, southern Florida and the Florida Keys should
monitor the progress of Eta through the week.
