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.

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.

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.
