Heat Advisory

A Cooling Trend through the Week!

Tropical Weather Outlook

Hottest day will be Monday and Tuesday with a cooling trend following into the end of the week. Humidities will be dropping bringing us heat indexes below 100 degrees. Highest probability for rain is Wednesday with 30-60% chances south of the I-10/12 corridor.

A disturbance well east in the central subtropical Atlantic has a low (30%) chance of formation as it moves generally west-northwest. No local impacts are currently forecast for southeast Louisiana and south Mississippi. However, now is a great time to review your plans and supplies before they are needed.
