“State and local governments need every tool and resource available to respond to this rapidly approaching hurricane,” Vitter wrote. “Due to the serious nature of Tropical Storm Isaac and the worsening forecast by the National Weather Service, there is a clear and justified need for a federal emergency declaration to address this emergency situation.”

Tropical Storm Issac is predicted to reach Louisiana early Tuesday and has already caused the GOP National Convention to postpone events for Monday. There is also speculation that more events at the convention in Tampa, Fla., could be canceled depending on the severity of the storm.

Vitter said the National Weather Service has forecast that the storm would hit the southeastern coast of Louisiana at Category 2 Hurricane strength within the next 24 hours.

It has been seven years since Hurricane Katrina devastated parts of Louisiana and other Southeastern states. If Issac becomes more serious, Republicans don't want to portray an image of partying and excess at a convention while others are potentially in danger from the storm.

Jindal was scheduled to speak at the convention but decided to stay in Louisiana during the storm.
