Key Factors
- 01 Flood Watch active: flash flooding possible from 8 AM EDT through Wednesday evening (July 29 8:00 PM EDT).
- 02 Thunderstorm coverage increases through the day (roughly 11 AM–5 PM) with PoP rising to ~60–64% and remaining high later.
- 03 Evening risk is highest: PoP ~78–85% from 6 PM through 11 PM with storms that could produce heavy rain.
- 04 Flood Watch indicates rainfall rates of 1 to 3 inches per hour possible and localized totals 2 to 5 inches (locally higher), which can rapidly flood roads and reduce visibility.

Recommendation
Avoid driving during the worst periods. If you must travel, the safest window is likely late morning before storms peak: 9:00 AM–11:00 AM. A second, somewhat better option is earlier evening before the heaviest nighttime period: 6:00 PM–7:00 PM; after 7:00 PM conditions deteriorate with storms/possible heavy rain—use extreme caution or wait.
