The tropics are beginning to provide a bit of action with Tropical Depression 4 developing off the coast of South Carolina, according to the National Hurricane Center. Another disturbance in the central tropical Atlantic Ocean weather is worth watching closely in what is still the first month of the 2021 hurricane season.
The depression is located less than 190 miles east-southeast of Hilton Head, South Carolina, and is producing a large area of showers and thunderstorms mainly west of the center.
The depression 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. 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.
Another area we’re keeping an eye on is 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.
