Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 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 Tropical
Storm Bill, located a few hundred miles east-southeast of
Nantucket, Massachusetts.

Disorganized showers and thunderstorms continue over the Bay of
Campeche and southern Mexico in association with a broad low
pressure area. This system is expected to move little during the
next day or two, and any development should be slow to occur during
that time period.  However, the disturbance should begin to move
northward by Thursday, 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 will continue 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.

Showers and thunderstorms have decreased and become less organized
during the past several hours in association with a tropical wave
located a few hundred miles south of the Cabo Verde Islands.
Development, if any, should be slow to occur during the next couple
of days while the wave moves westward. Thereafter, a combination of
dry air aloft and strong upper-level winds should limit the chances
of formation when the wave reaches the central tropical Atlantic.
* Formation chance through 48 hours...low...10 percent.
* Formation chance through 5 days...low...10 percent.
