Wave Off Southeast Florida Likely to Become Tropical Depression

We have been monitoring a weak area of low pressure off the southeast coast of Florida. It is causing heavy rain in the Bahamas and will increase rain chances in southern Florida. Land interaction today is limiting organization, but it is expected to move into the Atlantic this weekend into an area more conducive for development.

The National Hurricane Center gives it a 70% chance of development over the next 5 days. Models keep the wave near southern Florida before turning northeast and moving out into the Atlantic .

At the moment, heavy rain looks to be the main impact, with the deepest moisture staying east of us. But depending on its development and exact track that could change.

Another tropical wave in the Atlantic has minimal chances of development into early next week. It is currently a disorganized area of showers and storms, sitting several hundred miles east-southeast of the Windward Islands. There are still several days before it could impact any land areas.

Chantal Forms Over Open Atlantic; Another Disturbance To Watch Near The Bahamas

Hard to believe we went a full 37 days without a single named storm in the Atlantic, but we knew that streak would end at some point – especially with the peak of hurricane season fast approaching. Sure enough, Tropical Storm Chantal formed late Tuesday evening in the middle of North Atlantic shipping lanes.

Chantal isn’t going to do much. Forward motion should slow by the end of the week, and it’ll dance around the middle of the ocean. No impact to land is expected.

We’re also watching an area disturbed weather near the Bahamas. It’ll be battling some pockets of moderate wind shear over the next few days that should prevent any development. Next week however, environmental conditions will likely become more conducive, and it’s possible a tropical depression or storm will form off the Southeastern coast of the U.S. It’s far too early to say what, if any, U.S. impacts there may be. The next name on the list would be ‘Dorian’.

0Z 8/21 ECMWF Model Run valid for next Wednesday (8/28) evening.

6Z 8/21 GFS Model Run valid for next Wednesday (8/28) evening.

Historically speaking, about two thirds of all activity in the Atlantic occurs between August 20 and October 10. The season is young.
