The New Orleans area remains under a high wind warning after the bulk of a storm that produced at least one tornado and knocked train cars off their tracks has passed, according to the National Weather Service.

Weather Service officials urged residents to continue exercising caution after the worst of the storm passed.

A high wind warning is in effect until 2 p.m. Winds of between 40 mph and 55 mph are expected to start about half an hour after the rain passes and last at least an hour.

Wind gusts of up to 70 miles per hour have been reported at Louis Armstrong International Airport, which lost power during the storm.

There were reports of a tornado touchdown in Belle Chase near the Naval Air Station, moving northeast at 25 mph.

There were also reports that train cars had been blown off the elevated tracks near the Huey P. Long Bridge in Jefferson Parish and reports of damage to homes in the area.

The tornado warning covers most of Orleans, Jefferson and St. Bernard parishes and officials are warning residents to take cover. A tornado watch remains in effect until 1 p.m.

The weather service is urging residents to take cover in “the closest substantial shelter” in an interior room of a building and away from areas that flying debris could hit.

“Heavy rainfall may obscure this tornado,” according to the warning. “Do not wait to see or hear the tornado.”

Entergy is reporting thousands of outages in the New Orleans area, with large swaths of Jefferson Parish without power.

A thunderstorm warning also remains in effect.

The University of New Orleans is also closed and has cancelled classes for the day.
