Severe Weather Update - February 17, 2022 6 AM CST

Click HERE, HERE, and HERE for an update concerning the severe weather threat today.

Changes from the previous update:

  • The threat of severe weather has not changed, nor has the area of greatest threat.

  • A Wind Advisory has been issued for all of South Mississippi and southeast Louisiana through 6 PM CST this evening.

Overview:

WHAT:  MARGINAL RISK to SLIGHT RISK of Severe Weather

WHEN: Mainly during the afternoon and early evening between noon and 10 pm CST, although a few storms could develop late morning.

WHERE: Areas generally along and north of the Interstate 10 corridor, with the greatest threat across southwest Mississippi and the adjacent southeast Louisiana parishes.

CONFIDENCE: We are confident there will be thunderstorms across the area. We have low to moderate confidence that a few of the storms could become severe, especially over southwest Mississippi.

Impacts:

The main threats associated with any severe storms will be:

  • Wind gusts greater than 60 mph will be the main threat and could damage trees and powerlines.

  • Large hail and one or two tornadoes cannot be ruled out. The tornado threat will gradually diminish during the afternoon hours.

  • Generally, less than 1 inch of rain is forecast, but locally higher amounts could still lead to ponding of water in low-lying areas and areas of poor drainage.

Additional impacts outside of the severe weather threat include:

  • Gusty winds during the daylight hours today. Sustained south winds of 20-30 mph are expected. Gusts in excess of 40 mph likely, possibly as strong as 50 mph across southwest Mississippi and the Baton Rouge metro area.

  • Higher than normal tides are expected to gradually diminish later today along southeast-facing shores east of the Mississippi River.
