Tropical storm Barry is headed toward southern Louisiana and a storm surge warning is already in effect. The highest storm surge is expected between Intracoastal City on the Vermillion River and Shell Beach on the Mississippi River.
A hurricane warning has already been issued for the Louisiana coast. Residents are being encouraged to “rush” their preparations because tropical storm conditions were expected to arrive in the warning area by Friday morning.
As with Harvey in 2017, the greatest concern is that Barry is a slow-moving storm that will produce heavy rains and a flood threat along the central Gulf Coast and through the lower Mississippi Valley for approximately the next week.
Early estimates are for more than 20 inches of rain to fall in some areas. The National Weather Service said that potential impacts include “widespread and significant flash flooding” and “moderate to major flooding.” The service currently shows the Mississippi River at 16.51 feet in New Orleans and flood stage is 17.
