(NEW ORLEANS, La.) -- Tropical Storm Isaac's plodding pace through the Gulf of Mexico means the slow-moving storm could punish coastal areas with up to 36 hours of tropical winds and 10 to 16 inches of rain, Louisiana Gov. Bobby Jindal warned Monday.
Isaac, which is packing winds of 65 mph, is expected to strengthen to a Category 1 hurricane with winds of at least 74 mph by the time it reaches land late Tuesday or early Wednesday.
Jindal said the threat that New Orleans would be inundated on the seventh anniversary of the devastating Hurricane Katrina was lessening.
FEMA director Craig Fugate and the National Hurricane Center's Dr. Rick Knabb say there has been too much focus on New Orleans bracing for Isaac on the anniversary of Katrina.
"I think people need to understand this is not a New Orleans storm. This is a Gulf Coast storm," Fugate said today.
Fugate and Jindal warned people in low lying areas to get out of Isaac's way.
"Today is the day," Jindal said. "Today is the final day you should be taking any final precautions. If you want to evacuate, today is the day to do that."
Overnight, 50,000 people had already evacuated from southeast Louisiana's St. Charles parish. In addition, 2,000 jail inmates have been moved out of Isaac's expected path.
Jindal said over 4,000 National Guardsmen will be mobilized in case of emergency, but said he does not anticipate having to activate contraflow highway rules for evacuation purposes.
While not packing winds of some stronger hurricanes, Isaac's slow pace means it "could actually cause more damage," the governor said.
He said the storm could batter areas with tropical winds for up to 36 hours and could dump more than a foot of rain while lingering over some areas.
Jindal said he is skipping the Republican National Convention in Florida where he was expected to speak because of Isaac. "I will not be speaking or attending the Republican National Convention in Florida. There is no time for politics here in Louisiana," he said.
Fugate warned that Isaac's biggest punch may land in Alabama or Mississippi. The National Hurricane Center said to expect a storm surge of at least six feet with the possibility it could reach up to 12 feet.
Alabama and Mississippi have already joined Louisiana in declaring states of emergency. A tropical storm warning is in effect along the Texas and Louisiana border.
The storm is currently off the west coast of Florida and is moving in the direction of the northern Gulf Coast.
