Key Factors
- 01 Active Flood Watch (Severe) for flash flooding potential; multiple rounds of showers/thunderstorms expected with possible 1–3 in/hr rainfall rates and localized 3–5 inch totals (main hazard window begins around noon).
- 02 Hourly forecast shows thunderstorms becoming likely mid-afternoon into evening (roughly 2pm–8pm) with high precipitation probabilities (about 56–80%), increasing risk of hydroplaning and flooded/impassable low-lying roads.
- 03 Rain and thunderstorms continue into the evening/night with elevated chances (often 38–75%), so hazardous conditions may persist after dark.
- 04 Visibility data is not provided; thunderstorms/heavy rain can sharply reduce visibility, adding uncertainty but increasing concern.

Recommendation
If you must drive, the safer morning window is 7:00am–11:00am EDT (mostly sunny with very low precip chances). Avoid driving from about 12:00pm–9:00pm EDT due to likely thunderstorms and flood risk. A relatively safer evening option is 10:00pm–12:00am EDT when storm chances trend lower than earlier, but still be alert for lingering showers and any flooded roads; do not drive through standing water.
