Two tropical waves pose storm threats in the Atlantic and Caribbean

Aug. 28 (UPI) -- A pair of tropical waves in the central Atlantic and Caribbean don't pose a significant threat of tropical storm activity -- at least into the weekend.

The National Hurricane Center is tracking the two waves, one of which was located at 6:30 p.m. EDT Wednesday in the central Tropical Atlantic and extended southward into northeast Venezuela and northern Guyana.

The wave is traveling westward at between 10 to 15 mph and has a 20% chance of becoming a tropical storm within the next seven days, according to the NHC.

The system is producing localized rain showers over abroad area and could slowly develop into a tropical storm over the weekend and into the middle of next week. The NHC says it will pass through Puerto Rico and the Virgin Islands through Thursday.

Another tropical wave was located early Wednesday evening moving westward at 10 to 15 mph in the central Caribbean.

That tropical wave has convection limited to near its center and is unlikely to become a tropical storm, according to the NHC.

The system is producing showers and thunderstorms over the northwest Caribbean, most of Cuba and parts of Nicaragua and Honduras.

The system also is producing scattered showers and thunderstorms over Jamaica and Hispaniola and waves of between 4 and 5 feet in the south-central Caribbean, 2 to 4 feet in the central Caribbean and 1 to 3 feet in the northwest Caribbean near Costa Rica and Panama.
