As the cleanup from Hurricane Irene continues, more dangerous storms are headed toward the U.S.
Tropical Storm Lee, the 12th named storm of the season, dumped between 6 to 10 inches of rain along the Louisiana and Mississippi coast Sunday as it continued its slow move inland.
Water seeped into some homes and businesses in Louisiana, and there were power outages and some evacuations in the bayou area.
AccuWeather says Lee could be America's next billion dollar disaster, dumping up to 20 inches of rain and threatening residents from Florida all the way to Texas.
"In a nutshell, just way too much water in this area that you are going to have to overcome. There is a lot of low lying areas here." AccuWeather meteorologist Jim Kosek said.
Louisiana is bracing for possible flash floods, and New Orleans residents are being urged to stock up on food and water. Oil rigs in the Gulf of Mexico have begun evacuating personnel.
Forecasters also have their eyes on another storm, Katia, which briefly strengthened to a hurricane Thursday.
The system could become a major hurricane again by this weekend, although some forecasters say Katia is not on track to make landfall.
Experts say the Gulf storm is so slow moving it could hover right over the Gulf Coast for days triggering massive flooding.
"If we do get the rainfall, in a short period of time, that they are in fact predicting, we can predict with some confidence that there may be water that accumulates on the streets of New Orleans," New Orleans Mayor Mitch Landrieu said.
Meanwhile, Texas has literally been burning up from its extended drought, and has needed rain desperately.
But as one official said, sometimes you get more than what you need.
