Tropical Storm Isaac has formed in the western Atlantic with winds of 40 MPH. Gradual strengthening is expected in the next couple of days and this could become a hurricane as early as Thursday as it turns for a likely landfall in Cuba by the weekend and from there, the exact track is not very clear. Still, the Florida Peninsula may be one of the most likely targets as models consistently took it over South and/or Central Florida. Interests in much of Cuba, Dominican Republic, Haiti, Puerto Rico, US Virgin Islands & surrounding areas need to be the most alert for this potentially dangerous system. It could be near category two intensity by the time it goes into Cuba so some troubles there. Florida Peninsula and the rest of the SE/Gulf US Coast also need to pay attention for further trends and future threats to land.
Invest 96L is getting its act together and a TD/TS forming out of this is now much more likely. Still not a tropical cyclone and the threat to land, if any, is unclear at this time as models have been all over the place.
