Tropical Weather Outlook

200 PM EDT Mon Sep 9 2019

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

The National Hurricane Center is issuing advisories on Tropical 
Storm Gabrielle, located over the north-central Atlantic Ocean.

A weak area of low pressure, associated with a tropical wave, 
centered about 1200 miles east of the Lesser Antilles continues 
to produce disorganized showers and thunderstorms. Some slow 
development of this system is possible during the next two or 
three days before upper-level winds become unfavorable for 
tropical cyclone formation. This system is expected to move 
generally westward across the tropical Atlantic Ocean for the 
next several days.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.

Disorganized cloudiness and showers located a few hundred miles 
north of Hispaniola are associated with a surface trough 
interacting with an upper-level low. Little-to-no development of 
this system is expected during the next day or two while it 
moves west-northwestward near the southeastern Bahamas. 
Environmental conditions could become a little more conducive 
for development when the disturbance moves near the northwestern 
Bahamas, south Florida and over the southeastern Gulf of Mexico 
late this week.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.

A tropical wave currently near the west coast of Africa is 
expected to move quickly westward during the next several days. 
Some slow development is possible late this week or over the 
weekend when the system is several hundred miles east of the 
Lesser Antilles.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...20 percent.
