...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS TODAY INTO TONIGHT
ACROSS A SMALL PORTION OF SOUTHEASTERN LOUISIANA AND
COASTAL MISSISSIPPI...

Given the ongoing and anticipated evolution of Marco, potential for convection capable of producing tornadoes is becoming increasingly unclear. This threat seems largely conditional at this point, and limited to immediate Gulf Coastal areas.
Rainfall associated with Hurricane Laura.
Prepare for life-threatening rainfall flooding having possible extensive impacts across southwest and west-central Louisiana.

Potential impacts include:
- Major rainfall flooding may prompt many evacuations and rescues.
- Rivers and tributaries may rapidly overflow their banks in multiple places. Small streams, creeks, canals, and ditches may become dangerous rivers. Flood control systems and barriers may become stressed.
- Flood waters can enter many structures within multiple communities, some structures becoming uninhabitable or washed away. Many places where flood waters may cover escape routes. Streets and parking lots become rivers of moving water with underpasses submerged. Driving conditions become dangerous. Many road and bridge closures with some weakened or washed out.
Prepare for life-threatening wind having possible extensive impacts across Southwest Louisiana and Southeast Texas. Potential impacts include:

- Considerable roof damage to sturdy buildings, with some having window, door, and garage door failures leading to structural damage. Mobile homes severely damaged, with some destroyed. Damage accentuated by airborne projectiles. Locations may be uninhabitable for weeks.
- Many large trees snapped or uprooted along with fences and roadway signs blown over.
-Some roads impassable from large debris, and more within urban or heavily wooded places. Several bridges and access routes impassable.
- Large areas with power and communications outages.
