MARGINAL RISK of Heavy Rainfall through Wednesday evening WHEN: Now through Wednesday morning WHERE:

Tuesday: Along and North of the I-10/I-12 corridor for heavy rainfall; Across Southeast Louisiana and Southern Mississippi for severe weather

CONFIDENCE:

• We are confident there will be thunderstorms across the area and that a line of storms will likely continue to develop through the morning and into the afternoon hours. We have less confidence in exactly where that may occur.

• If and where that happens will be the main key in impacts. A shift of 10-20 miles could make all of the difference.

Impacts:

• Additional rainfall of 2 to 4 inches with locally higher amounts will be possible now through Wednesday morning

• Locations, where any band sets up, could experience flash flooding with life-threatening flash flooding possible in areas that receive the most rain

• Wind gusts greater than 60 mph and hail up to 1" in diameter will be the primary threats

• An isolated tornado can not be ruled out

The attached briefing below highlights the threats associated with this system.
