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.
