Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 AM EDT Tue Jun 15 2021

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

The National Hurricane Center is issuing advisories on recently 
upgraded Tropical Storm Bill, located more than 300 miles  
east-northeast of Cape Hatteras, North Carolina.  

1. Disorganized showers and thunderstorms continue over the Bay of 
Campeche in association with a broad low pressure area. Gradual 
development of this disturbance is possible during the next couple 
of days while it meanders near the coast of Mexico.  The system 
should begin to move northward by midweek, and a tropical depression 
is likely to form late in the week when the low moves across the 
central or northwestern Gulf of Mexico. Regardless of development, 
heavy rainfall is possible over portions of Central America and 
southern Mexico during the next several days.  Heavy rains could 
also begin to impact portions of the northern Gulf Coast on Friday. 
Please consult products from your local meteorological service for 
more information. 
* Formation chance through 48 hours...low...20 percent. 
* Formation chance through 5 days...high...70 percent.

2. A tropical wave located several hundred miles south of the Cabo 
Verde Islands is producing a large area of cloudiness and 
disorganized showers. Any development of this system should be slow 
to occur during the next few days. Thereafter, a combination of dry 
air aloft and strong upper-level winds will limit chances of 
formation while the wave moves over the central tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...20 percent.
