On this Sunday night (August 16th, 2020), NHC is closely monitoring two tropical waves over the tropical Atlantic Ocean, each having a medium (50 percent) chance of formation during the next five days.
One is a fast-moving tropical wave located about 500 miles east of the Windward Islands.
This disturbance is expected to move westward at about 20 mph during the next few days, but that fast forward speed is likely to limit significant development while the system approaches the Windward and southern Leeward Islands on Monday, and moves across the eastern Caribbean Sea on Tuesday.
After that time, however, the system is expected to move more slowly westward across the central and western Caribbean Sea, where upper-level winds could become more conducive for the development of a tropical depression during the middle-to-latter part of this week.
The second tropical wave is located over the far eastern tropical Atlantic ell to the southeast of the Cabo Verde Islands is producing a large area of cloudiness and disorganized showers.
The wave is forecast to move westward at 15 to 20 mph during the next few days, and environmental conditions are expected to become more conducive for the development of a tropical depression during the middle-to-latter part of this week while the system moves across the central tropical Atlantic.
