Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 AM EDT Mon Jun 28 2021

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

1. A well-defined low pressure system located about 190 miles 
east-southeast of Hilton Head Island, South Carolina, is producing a 
large area of showers and thunderstorms mainly west of the center. 
However, any additional increase in organization of the thunderstorm 
activity would result in the issuance of advisories for a tropical 
depression or tropical storm later this morning or afternoon.  The 
low is forecast to move west-northwestward at 15 to 20 mph, and the 
system should reach the coast of southern South Carolina or Georgia 
by this evening.  If advisories are initiated, then tropical storm 
warnings could be required for a portion of the Georgia and South 
Carolina coasts with short notice. Regardless of development, a few 
inches of rain are possible along the immediate coasts of Georgia 
and southern South Carolina through Tuesday.  An Air Force Reserve 
Unit reconnaissance aircraft is scheduled to investigate the system 
this afternoon.
* Formation chance through 48 hours...high...70 percent.
* Formation chance through 5 days...high...70 percent.

2. A broad area of low pressure associated with a tropical wave is 
producing a small cluster of showers and thunderstorms over the 
central tropical Atlantic Ocean.  Some slow development is possible 
through the end of the week while this system moves quickly westward 
to west-northwestward at about 20 mph, likely reaching the Lesser 
Antilles Wednesday night.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...medium...40 percent.
