The heavy rainfall poses risks of flash flooding, particularly in urban areas, low-lying regions, and near rivers and creeks. In Texas, life-threatening flooding is possible, especially in the Austin and San Antonio corridor. The Gulf Coast and Lower Mississippi Valley are also at risk, with localized totals of up to 8 inches of rain. In the Ohio Valley and Appalachians, recent rainfall has primed soils, increasing the likelihood of rapid runoff and rising waterways. Structural flooding, impassable roads, and dangerous conditions are expected in several areas, including New Orleans and coastal communities.
