Rain chances Tuesday with below average temperatures


It has been another hot day Monday across much of the WGNO viewing area. A Heat Advisory continues to remain in effect from 10AM until 6PM with index values between 100-105 degrees for some. Please be intentional in staying as cool as you possibly can.

Rain chances were quite widespread this afternoon on radar, and many spots experienced heavy downpours that could lead localized flash flooding with traditional drainage systems covered by debris. Please have a way to receive warning information on hand, though most of the heaviest downpours have ended. Still, a flood warning is issued across parts of the Northshore and our Mississippi Counties with Pearl River levels above flood stage.

This is primarily for the Pearl River at Minor Flood Stage. Remember the phrase “turn around, don’t drown” if encountering flooded roadways

Rain chances will remain moderate throughout your week, and we are closely watching Invest 91L near the Yucatán Peninsula.

I am closely watching the forecast for late-week as a small area of unorganized storms brings heightened rain chances in Mexico before moving north. Right now, this is something worth keeping up with but not stressing over. Since last Friday, the National Hurricane Center has not increased development chances whatsoever. There is a 0% chance this develops over the next 2 days and still only a 30% chance it develops over the next 5 days. Regardless of steering, our environment will not allow a rapidly strengthening hurricane like it did one week ago given chopped up Gulf of Mexico water, wind shear and dry air. A cold front on its way late week will steer this Gulf moisture east, likely closer to Alabama’s coastline or Florida’s coastline, increasing rain chances there. Models are not agreeing on any development, which is always a good sign. We certainly do not need any more rain in WGNO’s viewing area, much less another storm. This does not concern me, so please continue focusing only on your clean up efforts, and I will keep you posted. If anything, anticipate a rainmaker along this farther east Gulf Coast region. The system will not be a big deal elsewhere and only would be here as a result of so much damage throughout southeast Louisiana. Here tonight to bring you the latest!

Hurricane Larry is also not a threat here locally or across the United States as a whole.
