Isaac strengthens to hurricane that could flood 4 states
CHAUVIN, La. (AP) - Isaac has become a hurricane that could flood the coasts of four states with storm surge and heavy rains on its way to New Orleans.
Residents are hunkered down behind levees fortified after Katrina struck the city seven years ago this week.
Shelters are open for those who chose to stay or missed the chance to get away before the outer bands of the large storm blow ashore ahead of a forecast landfall in southeast Louisiana tonight or early tomorrow. However, with the exception of some low-lying areas, officials have not ordered mass evacuations.
The U.S. National Hurricane Center in Miami says Isaac became a Category 1 hurricane today with winds of 75 mph.
