The track of Isaac has proven to be a challenge to The National Hurricane Center experts. Isaac is simply indecisive because the center of circulation has been difficult to find. In fact, the center has reformed in several places the last few days, which has lead to the slight shifts on the cone of concern. Although the system is not well organized, tropical storm force winds are being clocked pretty much everywhere. This supports the fact we have a tropical storm in the Caribbean Sea.
A couple things can happen with Isaac's future:
Scenario One: If the center of Isaac stays over water longer, the impacts across the islands will be delayed because it will miss the mountains altogether. The impacts for Florida will also be put on hold.
Scenario Two: If the center interacts with the high terrain moving over Cuba. It should keep Isaac in check and weak.
What we do know is that the track is highly uncertain. Right now the latest forecast track has Isaac clipping Haiti and moving over Eastern Cuba on Saturday. By Sunday, it should emerge into the Florida Straits where it will have the opportunity to gain some strength as it moves through the Lower Florida Keys early Monday.
I know we have been receiving messages and phone calls by people wanting to know what can we expect out of Isaac in South Florida?
Saturday: Expect it to turn windy. We have high pressure weakening and with Isaac to our South entering Cuba a large pressure will exist. This pressure difference will allow the wind to pick up and bring in some speedy tropical type showers.
Sunday and Monday: Tropical Storm conditions are possible with 30-45mph winds. Clouds and rain likely. About 4 to 8 inches of rain are possible through early next week for South Florida.
Of course this local forecast will heavily depend on what happens with Isaac.
