Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Sun Aug 20 2023

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

Active Systems:
The National Hurricane Center is issuing advisories on Tropical 
Depression Six, located several hundred miles east of the northern 
Leeward Islands and on newly formed Tropical Storm Emily, located 
about 1000 miles west-northeast of the Cabo Verde Islands.

Eastern Caribbean (AL90):
Showers and thunderstorms continue to show signs of organization in 
association with an area of low pressure over the eastern Caribbean 
Sea. In addition, visible satellite imagery shows evidence that a 
well-defined center is developing, and earlier satellite wind data 
indicated the system was producing winds of 35-40 mph. If these 
trends continue, a tropical depression or storm could form as soon 
as later this afternoon. A NOAA Hurricane Reconnaissance mission is 
currently en route to investigate the system this afternoon. The 
system is forecast to move westward to west-northwestward at 10 to 
15 mph over the eastern and central Caribbean, before turning 
northward and potentially affecting the Dominican Republic and Haiti 
on Tuesday or Wednesday, where tropical storm watches could become 
necessary later this afternoon. Regardless of development, heavy 
rainfall is possible over portions of the Lesser Antilles during the 
next couple of days. Interests in the eastern and central Caribbean 
should monitor the progress of this system.
* Formation chance through 48 hours...high...90 percent.
* Formation chance through 7 days...high...90 percent.

Western Gulf of Mexico (AL91):
Showers and thunderstorms have increased this afternoon in 
association with an area of disturbed weather located in the eastern 
Gulf of Mexico. Additional development of this system is possible as 
it moves westward at about 15 to 20 mph, and a tropical depression 
could form as it approaches the western Gulf of Mexico coastline by 
Tuesday.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 7 days...medium...60 percent.

Eastern Tropical Atlantic:
A large area of disorganized showers and thunderstorms over the far 
eastern tropical Atlantic is associated with a tropical wave 
centered just southeast of the Cabo Verde Islands. Environmental 
conditions appear conducive for gradual development of this system, 
and a tropical depression could form later this week while it moves 
west-northwestward across the eastern tropical Atlantic.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 7 days...medium...60 percent.
