HURRICANE: Eta Now Hurricane Strength, Continues To Churn

Unprecedented 28th Storm Of Season


BOCA RATON, FL ( — The National Hurricane Center has elevated the 28th storm of the season to Hurricane status. Hurricane Eta continues to churn in the Caribbean. While it is no threat to Florida or the United States mainland, it is unprecedented for there to be a 28th storm as November gets underway.

Here is the early morning discussion from the National Hurricane Center:

Hurricane Eta Discussion Number   7
NWS National Hurricane Center Miami FL       AL292020
400 AM EST Mon Nov 02 2020

Eta has continued to become better organized, with a distinct 
Central Dense Overcast surrounded by many banding features.  A 
low-level eye feature was seen in GPM Microwave Imager data, and 
Dvorak intensity estimates are at 65 kt from both TAFB and SAB.  
Based on this, the system is upgraded to a hurricane.  Continued 
strengthening is likely, given the very high oceanic heat content 
and only moderate easterly vertical shear.  The official forecast 
calls for rapid intensification, in line with the SHIPS Rapid 
Intensification Index which shows a 48 percent chance of a 30 kt 
increase over 24 hours.  Although not explicitly shown, Eta could 
very well be a 100-kt major hurricane when it crosses the coastline. 
After landfall, weakening will occur while the cyclone interacts 
with the very mountainous terrain of Central America.  Even though 
official forecast points are shown through day 5, it is doubtful 
that the surface circulation could survive after being inland that 
long over the mountains of Nicaragua and Honduras.  Although some 
of the global models are showing a cyclone over the northwestern 
Caribbean later this week and into the weekend, it is not certain 
whether this is Eta, or a new system that could form in that area.

The hurricane is moving westward, or at about 265/10 kt.  The track 
forecast philosophy remains basically unchanged.  For the next few 
days, Eta should move westward or west-southwestward to the south 
and southeast of a mid-tropospheric high pressure system centered 
near the western Gulf of Mexico coast.  The official track 
forecast is nearly identical to the previous one, and also very 
similar to the various model consensus predictions.

Since this is likely to be a very slow-moving system after it makes 
landfall in Central America, torrential rains and flooding will be 
a major threat from Eta.  

Key Messages:

1. Eta is forecast to continue to strengthen, and it could become a 
major hurricane before it reaches the northeastern coast of 
Nicaragua early Tuesday, where a Hurricane Warning is in effect.  A 
Tropical Storm Warning is in effect for a portion of the 
northeastern coast of Honduras.

2. 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.

3. A life-threatening storm surge, along with damaging waves, is
expected along portions of the northeastern coast of Nicaragua near
and to the north of where the center makes landfall.  Water levels
could reach as high as 10 to 15 feet above normal tide levels in
some parts of the hurricane warning area. Preparations to protect
life and property should be rushed to completion.

Is Hurricane Eta Going To Hit Florida?

Hurricane Eta is not forecast to come near Florida. It is churning in the Caribbean and is expected to continue on a westward track over the duration of the storm. The National Hurricane Center says that Hurricane Eta is the 28th named storm of the 2020 Atlantic Hurricane Season, which is unprecedented.hurricane eta
