Dennis strengthening, taking aim on Jamaica, Cuba, Gulf Coast
Dennis is currently posted at 65 mph with central pressure 994 mb. Dennis is very well organized and looks poised to become a hurricane later today, possibly in under an hour. Dennis appears to continue to have a dirty eye structure and is situated in a very favorable environment for development. He currently looks to strike Jamaica, the Cayman Island, and then Cuba before moving into the Gulf of Mexico. Once in the Gulf, the models are taking two distinct tracks. One brings Dennis up and strike the Florida panhandle. The other brings Dennis directly at New Orleans. Either right now is a possibility. In terms of intensity, this is will vary heavily based on where exactly Dennis strikes land. Mountains in Jamaica and Cuba both could significantly weaken Dennis if they interact with the eye structure. Look for Dennis to develop a very tight and powerful structure in the Caribbean and then spread out, becoming much work expansive, but weaker, once the core interacts with land or entrains dry air. More will be coming with the next advisory.
