Key Factors
- 01 The Flood Watch describes possible rainfall rates of 2–3 inches per hour and flooding in low-lying and poor-drainage areas.
- 02 The watch headline runs through July 22 at 2am EDT, but its structured end time is July 21 at 6am EDT; this inconsistency makes the exact alert window uncertain.
- 03 Daily forecasts indicate 1–2 inches of rain during the day and another 1–2 inches overnight, with heavy rain possible in thunderstorms.
- 04 Precipitation probabilities rise from 19% at 7–8am to 58–75% during much of the remaining morning, and 84–98% from 6–10pm.
- 05 Forecast winds are only 5–12 mph and temperatures remain well above freezing, but visibility and storm gust data are missing.

Recommendation
Postpone nonessential travel, particularly during the afternoon and 5–10pm EDT. The preferred morning slot is 7–8am EDT, when precipitation probability is lowest. For an evening slot, 10–11pm EDT is relatively less unfavorable than the peak evening period, but storms remain likely (68%) and flooding may persist; it is not a safe window. Check updated warnings and road conditions before departure, slow down in rain, and never drive through flooded roads.
