Residents in McDowell, Wyoming, Raleigh, and Fayette counties should remain vigilant for potential flash flooding, especially in low-lying and flood-prone areas. The Slight Risk designation indicates a moderate chance of excessive rainfall leading to localized flooding. Travelers and outdoor enthusiasts should exercise caution as heavy showers and thunderstorms may reduce visibility and create hazardous conditions. The risk diminishes by Sunday afternoon as drier weather begins to settle in.
