Heavy rainfall and flash flooding forecast across Texas, the Gulf Coast, and the Appalachians

A Slight Risk area for excessive rainfall remains in effect across southeast Texas, the central Gulf Coast, and parts of the Ohio Valley into the central Appalachians where slow-moving thunderstorms may produce flash flooding over saturated ground through May 27. Deep Gulf moisture and a slow-moving weather pattern are forecast to fuel multiple rounds of heavy rain from southeast Texas to the central Appalachians, increasing the risk of flash flooding in vulnerable areas through late week Source
