Cindy's top sustained winds had weakened from 50 mph to 35 mph by midmorning and it was downgraded to a tropical depression. It was expected to continue its decline while pushing through Alabama, said the National Hurricane Center in Miami.
Cindy's sustained winds earlier of 70 mph brought squalling rains and heavy downpours, reports Dave Cohen of CBS radio affiliate WWL-AM. Thousands of people were left with no electricity. Throughout metropolitan New Orleans, trees and power lines were down and debris was scattered.
But it was water that caused problems in Mississippi's coastal Hancock, Harrison and Jackson counties.
"We have recorded 3 to 4 inches of rain and we have a storm surge of 4 to 6 feet above normal tide. We have a number roads that flooded with rain water that presents a travel hazard," said John Edwards, a spokesman for the Harrison County emergency operations center.
Officials said the high water affected only areas that normally are prone to flooding.
By midmorning Wednesday, officials in Mississippi's coastal counties said water was draining from flooded streets and low-laying areas.
Fishermen returned to boats along the coast Wednesday but were already keeping watch on the next weather system, Tropical Storm Dennis.
Dennis, a larger and more powerful storm, could hit Florida as early as Friday, reports CBS News Correspondent Lee Cowan, and forecasters say it could well head back into the Gulf of Mexico and make a beeline for Louisiana and Mississippi early next week.
