"Regardless of development, heavy rainfall could produce localized flash flooding over portions of the north-central Gulf Coast through Friday," the National Hurricane Center said.

The risk of dangerous flooding continues along the Gulf Coast from a no-name storm system that could lead to days of an enhanced flood risk along and north of the Interstate 10 corridor.

A Level 2 of 4 risk is in place Thursday along the Gulf Coast from east Texas to the west Florida panhandle – including New Orleans, Mobile, Alabama, and Gulfport, Mississippi.
