Tropical Weather Outlook
NWS National Hurricane Center Miami FL
800 PM EDT Sun Jun 27 2021

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

1. A small low pressure system is located about 425 miles 
east-southeast of Savannah, Georgia.  The associated shower and 
thunderstorm activity has become less organized since earlier this 
afternoon, becoming displaced to the northwest of the surface center 
due to strong upper-level winds.  The low is forecast to move 
quickly west-northwestward at 15 to 20 mph, crossing over the 
warmer waters of the Gulf Stream Monday morning, and it has some
potential to become a tropical depression or tropical storm before 
reaching the coast of Georgia or southern South Carolina by Monday 
evening.  If the system becomes more organized overnight or on 
Monday, 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 
Monday night.  An Air Force Reserve Unit reconnaissance aircraft is 
scheduled to investigate the system Monday afternoon, if necessary.
* Formation chance through 48 hours...medium...50 percent.
* Formation chance through 5 days...medium...50 percent.

2. An area of low pressure associated with a tropical wave is 
producing a small cluster of showers and thunderstorms over the 
eastern 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 late Wednesday or Wednesday night.
* Formation chance through 48 hours...low...20 percent.
* Formation chance through 5 days...low...30 percent.
