Tropical Weather Outlook
NWS National Hurricane Center Miami FL
200 PM EDT Wed Jun 30 2021
For the North Atlantic...Caribbean Sea and the Gulf of Mexico:
1. Showers and thunderstorms associated with a broad low pressure area
and tropical wave located about 1300 miles east-southeast of the
Windward Islands have become better organized since yesterday.
However, recent satellite wind data indicates that the disturbance
does not have a well-defined circulation. Environmental conditions
appear generally favorable for continued development, and a tropical
depression or storm is likely to form during the next day or two
while the system moves west-northwestward at 20 to 25 mph.
Interests in the Lesser Antilles should closely monitor the progress
of this system, as advisories on a potential tropical cyclone,
accompanied by tropical storm watches for portions of this area, are
likely to be issued later today.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...90 percent.
2. Showers and thunderstorms continue in association with a tropical
wave located over the Lesser Antilles. This system has become less
organized since yesterday, and significant development is no longer
expected while it moves quickly westward across the Caribbean Sea.
The wave should continue to produce locally heavy rains over
portions of the Lesser Antilles through tonight.
* Formation chance through 48 hours...low...near 0 percent.
* Formation chance through 5 days...low...near 0 percent.
