The US National Hurricane Centre (NHC) has given two tropical waves over the Atlantic basin a low chance of formation during the next 48 hours and a medium chance during the next five days.
In its early morning outlook on Monday, NHC said the first is a fast-moving tropical wave located a couple of hundred miles east of the Windward Islands. It is producing disorganized shower and thunderstorm activity.
“This disturbance is expected to move westward at about 20 mph during the next few days, and that fast forward speed is likely to limit significant development while the system approaches the Windward and southern Leeward Islands today [August 17], and moves across the eastern and central Caribbean Sea on Tuesday and Wednesday,” The NHC said.
When the wave reaches the Western Caribbean Sea, it will encounter upper-level winds that could assist it to develop into a tropical depression during the latter part of this week.
Regardless of development, the NHC has forecast locally heavy rainfall and gusty winds over portions of the Windward and southern Leeward Islands beginning today through Tuesday morning.
The second tropical wave, which is located over the eastern tropical Atlantic to the south-southwest of the Cabo Verde Islands, is producing disorganized cloudiness and showers.
The wave is forecast to move westward to west-northwestward 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 and western portions of the tropical Atlantic.
