Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Wed Sep 16 2020

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

The National Hurricane Center is issuing advisories on Tropical 
Storm Sally, located inland over southeastern Alabama, on Hurricane 
Teddy, located over the central tropical Atlantic, and on Tropical 
Storm Vicky, located over the eastern tropical Atlantic. 

1. Showers and thunderstorms associated with a broad area of low 
pressure over the southwestern Gulf of Mexico have changed little 
in organization since yesterday.  Upper-level winds are forecast to 
gradually become more conducive for development, and a tropical 
depression is likely to form late this week or over the weekend 
while the low meanders over the southern Gulf of Mexico.
* Formation chance through 48 hours...medium...50 percent. 
* Formation chance through 5 days...high...70 percent.

2. An elongated area of low pressure located a few hundred miles south 
of the Cabo Verde Islands is producing disorganized shower and 
thunderstorm activity.  Environmental conditions are expected to be 
conducive for development during the next few days, and a tropical 
depression could form before upper-level winds become less favorable 
over the weekend.  This system is forecast to move 
west-northwestward at 10 to 15 mph during the next several days.
* Formation chance through 48 hours...medium...40 percent. 
* Formation chance through 5 days...medium...60 percent.

3. A non-tropical area of low pressure is located over the far 
northeastern Atlantic Ocean a few hundred miles east-northeast of 
the Azores.  This system is forecast to move east-southeastward and 
then northeastward at about 10 mph over the next day or two, and 
its chances of acquiring some subtropical characteristics before it 
reaches the coast of Portugal late Friday appear to be decreasing.  
For more information on this system, see High Seas Forecasts issued 
by Meteo France. 
* Formation chance through 48 hours...low...10 percent. 
* Formation chance through 5 days...low...10 percent.
