100 PM EST Mon Nov 9 2020

For the North Atlantic...Caribbean Sea and the Gulf of Mexico:

The National Hurricane Center is issuing advisories on Tropical 
Storm Eta, located over the southeastern Gulf of Mexico.

1. Shower and thunderstorm activity associated with a low pressure 
system located several hundred miles southwest of the Azores has 
increased and become better organized during the past several hours. 
Satellite-derived wind data earlier this morning suggested that the 
system had not yet become distinct from a frontal boundary in the 
area, however, it will likely become non-frontal soon. The satellite 
data also indicated that the system is already producing gale-force 
winds. Additional development is expected, and a tropical or 
subtropical storm will likely form during the next day or two while 
the system moves eastward or east-northeastward over the 
northeastern Atlantic Ocean. 
* Formation chance through 48 hours...high...70 percent. 
* Formation chance through 5 days...high...80 percent.

2. A tropical wave is forecast to move over the central Caribbean Sea, 
where an area of low pressure could form in a couple of days. 
Environmental conditions are forecast to be conducive for 
development, and a tropical depression could form late this week 
or over the weekend while the system moves slowly westward.
* Formation chance through 48 hours...low...near 0 percent. 
* Formation chance through 5 days...medium...50 percent.

Additional information on the central Atlantic gale area can be 
found in High Seas Forecasts issued by the National Weather 
Service...under AWIPS header NFDHSFAT1 and WMO header FZNT01 KWBC.
