Flash Flood Risk in Lower Mid-Atlantic Tonight
US · Published Sep 23, 2026
• The Weather Prediction Center (WPC) has issued a Mesoscale Precipitation Discussion highlighting the potential for scattered flash flooding across the Lower Mid-Atlantic region.
• Showers and thunderstorms are developing along a quasi-stationary front stretching from the Virginia Tidewater to the Midlands of South Carolina.

Impact & Risks

The primary risk is scattered flash flooding, particularly in areas where storms produce intense rainfall rates of 2-3 inches per hour. While antecedent conditions are relatively dry and flash flood guidance values are high, the potential for cell training and reduced storm motion increases the likelihood of localized flooding. Residents in low-lying areas and regions near the quasi-stationary front should remain vigilant as rainfall totals could reach 3-5 inches in some locations by 03Z.
