Gulf States Deluge Persists Today

UPDATED by WeatherBug Meteorologists
The summer of significant flash floods rolls on as heavy rain will persist across the Gulf states today, leading to elevated flood concerns. The threat for heavy rain and flooding will gradually diminish on Friday.
The combination of a disturbance drifting through the Deep South, tropical moisture in place and a warm front will result in heavy rainfall from coastal Texas to the Florida Panhandle today. Thunderstorms within the moisture-rich, unstable environment may produce rainfall rates up to 3 inches per hour and combined with overly saturated soils will potentially lead to flash flooding. Coastal parts of Louisiana, Mississippi, Alabama and Florida will see the greatest impacts from the rain, with additional rainfall of 1 to 3 inches possible by this evening.
Flood Watches, Warnings and Advisories extend from far eastern Texas and into south-central Louisiana, southern Mississippi, southwestern Alabama and the far western Florida Panhandle. Cities under these flood-related threats include Beaumont, Texas, Alexandria and Lake Charles, La., and McComb, Jackson, Meridian, and Hattiesburg, Miss., Demopolis, Ala., and Pensacola, Fla.
This same system produced heavy rain and significant flooding in central Mississippi on Wednesday, especially in the Jackson Metro area, where 6 to 12 inches of rain fell and closed parts of Interstate 20. Life-threatening rains from this system also hit the Dallas-Fort Worth area on Monday. Slow-moving and repeated rounds of heavy rain and thunderstorms delivered widespread rainfall amounts of 5 to 10 inches with some amounts as high as 15 inches.
If you will be out and about, be sure to keep an eye to the sky and look out for rapidly changing cloud coverage. If you encounter flooded roadways, remember to “Turn Around, Don’t Drown!” In some cases, the thunderstorm that leads to flooding at your location could be many miles away.
