The centre of Tropical Storm Lee lurched across Louisiana’s Gulf Coast early Sunday, dumping torrential rains that threatened flooding in low-lying areas in a foreshadowing of what cities further inland could face in coming days.
At 5am EDT (0900 GMT), Lee had maximum sustained winds of 45mph (75kph), the US National Hurricane Centre said. It said Lee is crawling to the north at 2mph (4kph). A slow northeastward motion is expected as it treks across southern Louisiana, forecasters said.
Lee is forecast to dump 10 to 15 inches of rain in many areas in the coming days and up to 20 inches in scattered spots.
The storm stalled just offshore for several hours before meandering to the north and west.
Thousands of homes were without power.
