Key Factors
- 01 The Flood Watch description covers noon today through late tonight, with the headline ending at 4am EDT August 28. The structured end time instead lists noon today, creating timing uncertainty.
- 02 The watch warns of rainfall rates of 1–3 inches per hour and localized totals of 3–5 inches, with possible flooding in urban and poor-drainage areas.
- 03 Hourly precipitation probabilities peak at 80–85% from 2–8pm, with thunderstorms forecast. Heavy rain could reduce visibility and increase hydroplaning risk.
- 04 Temperatures remain well above freezing and sustained winds are only 1–9 mph; ice and sustained strong winds are not indicated.
- 05 Visibility measurements, wind gusts and actual road flooding conditions are not provided.

Recommendation
All times EDT. Prefer 7–8am for morning travel, when precipitation probability is 5%. For necessary evening travel, 9–10pm is relatively preferable at 32%, but only if roads are confirmed clear and no warnings are in effect. Avoid nonessential driving from noon through 8pm, especially 2–8pm; flood risk may continue late tonight. Check updated warnings, slow down in rain, increase following distance and never drive through floodwater.
