Isaac lost its hurricane status Wednesday afternoon, but its relentless waves of rain brought dangerous storm surge and flooding to much of coastal Louisiana.

The slow-moving system, downgraded to a tropical storm, threatened to keep churning for another day.

Dozens of families that had ignored mandatory evacuation orders in a low-lying area retreated to their attics and roofs and sought rescue amid the howling wind and pounding rain.

The punishing conditions will persist “all day today, into tonight, into tomorrow,” said Richard Knabb, director of the National Hurricane Center.

As of 2 p.m. CT, Isaac’s maximum sustained winds were at 70 miles per hour — below the hurricane threshold of 74 mph.

The storm’s center was about 55 miles south-southeast of Baton Rouge and about 50 miles west-southwest of New Orleans, the hurricane center said.
