Key Factors
- 01 Flash Flood Warning is active until 8:00 AM EDT due to flash flooding and continuing poor-drainage/underpass flooding; roads may still be affected after the heaviest rain.
- 02 Hourly forecast shows showers and thunderstorms likely through the morning (69–94% PoP from 7–10 AM, then still elevated with thunderstorms) with very wet conditions.
- 03 Daily forecast indicates 1 to 2 inches of rain possible (chance of precipitation ~90%); localized higher totals could worsen flash flooding.
- 04 Gusts as high as 21 mph are forecast with thunderstorms, which can increase handling difficulty for light/sport and high-profile vehicles.
- 05 After 11 AM, thunderstorms remain possible to likely (2–5 PM especially), so flood risk may persist beyond the morning warning window.

Recommendation
Avoid driving during the morning warning window (7:00–8:00 AM EDT, and use extra caution through about 10:00 AM). If travel is necessary in the evening, the safer window is 7:00–8:00 PM EDT when the forecast shifts to partly cloudy/slight chance (PoP drops to ~5% at 7–8 PM).
