Isaac Update: Storm Slowly Weakening, But Still Soaking Louisiana

Latest from the National Weather Service:

"Isaac is slowly weakening as it continues to move over land. Winds have decreased to 45 mph and Isaac is expected to become a tropical depression by Thursday evening. The center of Isaac will continue to move over Louisiana on Thursday, over Arkansas on Friday and over southern Missouri Friday night. Life-threatening hazards from storm surge, inland flooding and tornadoes are still occurring."

The frustratingly slow-moving storm spent most of yesterday camped out near the coast, dumping as much as 20 inches of rain in some areas of Louisiana. Levees and pumps in New Orleans held up, thankfully, but things are a little more dicey in the rest of the state, where roughly a third of households were left without power, according to NBC News.

Heavy rain and winds are expected to continue to pound much of the region for the remainder of today, if not into tomorrow. That, CNN reports, has prompted authorities to urge residents of a handful of towns outside of New Orleans to get out while they still can ahead of the rising waters brought on by Isaac.
