An area of low pressure with a front will set the stage for locally heavy rainfall that may lead to flooding or flash flooding across portions of the Piedmont and Shenandoah Valley. Many of these areas have already seen their share of rain over the past several days and weeks. Any additional rain over fairly saturated ground will likely cause flooding, especially across low-lying and poor drainage areas. For this reason, a FLOOD WATCH has been issued for much of the Shenandoah Valley, including portions of the Roanoke and New River Valleys through late Monday night.
NEW DATA shows rain moving in during the morning hours (sooner than the previous forecast) and the heaviest rain further southwest. The heaviest rain looks to fall across portions of the New River and Roanoke Valleys, Blue Ridge and into the Central Shenandoah Valley. This would include areas such as Radford, Blacksburg, Roanoke, Lexington, Covington, Staunton, and Charlottesville.
