The story of Hurricane Isaac will more than likely be one of flooding. The National Hurricane Center says that some places along the Mississippi and Louisiana coast could see up to 18 inches of rain.

Over five days, the tropical system will spread rain far and wide.

How widespread, you ask? Look at this map put together by the National Oceanic and Atmospheric Administration. It shows their prediction of how much rain will fall in the next five days:

The National Weather Service has issued an alert for New Orleans East and upper St. Bernard Parish, due to a cluster of strong, slow-moving thunderstorms affecting the area.

The storms, located northeast of Chalmette, are moving to the northeast at approximately 5 mph, and packing frequent lightning and wind gusts up to 35 to 45 mph, according to the Weather Service.

The National Weather Service has issued a weather alert this evening for parts of four parishes, in advance of a cluster of strong thunderstorms approaching the region.

The storms, which are moving north at about 5 mph, may produce one to two inches of rain in a short period of time, says the Weather Service. That much rain may result in the ponding of water around low-lying roadways.

The alert covers upper Jefferson, Plaquemines and St. Bernard Parishes, as well as New Orleans and New Orleans East.
