Tropical Storm Issac Strengthening Bound For Southern Leeward Islands

Issac Close To Hurricane Strength

Threat Grows for Southern Leeward Islands

In what is a very busy Atlantic Basin at the moment we have 2 hurricane in Florence and Helene and we have Tropical Storm Issac between them which is just under hurricane strength and heading westward. Issac is the smallest of the 3 systems in terms geographic coverage but it is aiming for the Southern Leeward Islands for the middle of this coming week.

Conditions are favorable for Issac to strengthen to a hurricane in the next 24 hours. With Florence pulling away to the west there is plenty of room for Issac to develope without any interference from either Florence generated wind wind hear or shear of any kind . The ridge to the north of Issac takes it straight westward.

Last year the Leeward Islands dealt with two devastating category 5 hurricane in Irma and Maria and just missed a third with Jose. With Issac it seems minimal hurricane is the worst case scenario here though small systems sometimes can find a way to overdevelop. It seems that conditions will be favorable until it gets close to the Leewards where wind shear issues could get in the way. It also should start moving faster to the west which means watches could go up Monday for parts of the Northern Windward or Southern Leeward Islands.
