Tropical Storm Isaac will likely be skirting the west coast of Florida late this weekend into early next week, with potentially flooding rainfall. Then, the storm could make landfall just east of New Orleans along the Gulf Coast as a Category 1 hurricane. Currently, Isaac is not all that strong with sustained winds at 50 mph, and it is moving west at 15 mph. The storm will struggle while crossing Haiti and Cuba, then strenghten over the Gulf of Mexico. (more below image)
The US hasn't been hit by a hurricane since Irene struck the Outer Banks of North Carolina last August. Plus, it's been the longest period of time on record since a major hurricane has hit the US. The last major hurricane was Wilma, which hit almost seven years ago in 2005.
What makes this storm interesting for us, is that it could eventually bring our area some widespread rainfall. These storms can sometimes bring strong winds and will need to be watched closely late next week (remember Ike, 2008). The first image below shows the heavy rain in Florida as the storm crosses the Gulf of Mexico late Sunday/early Monday. The middle image was from the 00z GFS weather model putting rain right over us next Thursday. However, the latest 12 z model below shows the storm all the way east into the Atlantic Ocean. This gives you an idea how crazy the models can be with tropical systems. The models do agree on a Gulf Coast landfall and skirting the west coast of Florida.
