Wind and tornado:
Sustained hurricane force winds are expected across a large swath of SE LA and coastal MS.
These winds could result in downed and uprooted trees, power outages, and damage to weaker and poorly constructed structures.
A few tornadoes will be possible in the storm’s rain bands mainly to the east of the center. Tornadoes in these situations are typically short-lived, but they move very quickly. The highest tornado threat will generally be across areas southeast of a line from Houma to Covington to Poplarville.
