Isaac on the Way. Many Potential Impacts.

Commentary

T.D. 9 should be upgraded to T.S. Isaac at some point today. Isaac has the potential to be a dangerous storm for Florida and parts of the Southeast into the Carolinas next week.

Right now, I am thinking it's a storm affecting the east coast of Florida, but I will still can see how it goes into the eastern Gulf of Mexico and the Florida Panhandle. I am about 60% on the east coast of Florida and 40% on the eastern Gulf.

While it's just speculation on the damage impacts on Florida from a hurricane, the Carolinas is the area that has the greatest potential to me. I posted a map below that shows the percentage of normal rainfall the past two weeks, and as you can see, the western Carolinas have become soggy. If Isaac were to come into that area, we could be talking about some massive flooding problems. Even if it went into the Florida Panhandle, you still have Alabama and Mississippi in the same boat with regards to soggy conditions. I guess one could say that the worse case would be for Isaac to go into the Florida Panhandle then up into the western Carolinas.

North of the Carolinas, conditions are not as bad in regards to the amount of rainfall. One would think given the river levels, that the river system could handle the heavy rains from a tropical system.

There is a lot riding on this storm, and it could be the storm that hits with the biggest impacts on the U.S.
