Days of intense, heavy rain fuel brewing flood threat across Texas through Memorial Day weekend

The FOX Forecast Center warned that in the threat zone, rainfall rates will be high, with 1 to 3 inches falling in a short time.

Days of heavy rain and thunderstorms are targeting the South, with Texas in the bullseye, for potential flash flooding through Memorial Day. 

This multi-day event is driven by moist air from the Gulf of America, which interacts with slow-moving disturbances in the upper atmosphere and a stalled front, fueling thunderstorm activity.

Louisiana, Arkansas and Mississippi should be on alert for flash flooding, with a level 1 out of 4 flash flood risk for most of the week. 

The FOX Forecast Center warned that in these zones, rainfall rates will be high, with 1 to 3 inches falling in a short time. 

With pockets of severe to extreme drought across the region, the rain is likely to lead to more flooding because the ground can't soak up all the moisture. 

HOW TO WATCH FOX WEATHER

As multiple storm systems move over the region, rain totals will continue to rise. 

By Memorial Day, upwards of 5 to 8 inches of rain could be possible.
