Key Factors
- 01 The Flood Watch text specifies 8 AM July 28 through 8 PM July 29 EDT, despite a conflicting structured end time of 8 AM July 28. Rainfall rates of 1–3 inches per hour are possible within the watch area.
- 02 Hourly precipitation chances rise to 60–71% from 2–6 PM and peak at 85% from 8–10 PM. Heavy rain could cause ponding, hydroplaning and reduced visibility.
- 03 The daily forecast allows 0.5–0.75 inch of daytime rain and another 1–2 inches overnight, increasing flooding concerns.
- 04 Winds are generally 3–10 mph with gusts up to 22 mph; temperatures remain well above freezing.
- 05 Visibility and actual road flooding observations are unavailable, so route-specific safety cannot be confirmed.

Recommendation
Prefer 7–8 AM EDT for morning travel, when precipitation probability is 11%. For an evening slot, 7–8 PM EDT is relatively less unfavorable than 8–10 PM, but still has a 74% precipitation chance and is not a safe window. Postpone nonessential driving from 2 PM through midnight, especially 8–10 PM; no reliably safe evening period is indicated. Check updated warnings before departure, slow down on wet roads, and never drive through floodwater.
