Key Factors
- 01 The Flood Watch description specifies noon through late tonight, with the headline ending at 2am EDT August 21; its structured end time instead says noon August 20, creating uncertainty about the exact alert window.
- 02 Possible rainfall rates of 1–3 inches per hour and localized totals of 3–5 inches could flood roads, poor-drainage areas, and low-lying routes.
- 03 The worst forecast period is approximately 2–8pm EDT, with precipitation probabilities of 56–80% and showers and thunderstorms likely or forecast.
- 04 Morning precipitation probabilities are only 1–9% from 7–11am. Forecast winds of 2–7 mph and temperatures well above freezing do not indicate strong sustained-wind or ice hazards.
- 05 Visibility, storm gusts, and actual road-flooding conditions are not provided. Forecast fog at 3–5am occurs August 21, not on today's date.

Recommendation
Prefer 8–10am EDT for morning travel. Avoid nonessential driving from noon through 8pm, especially 2–8pm. For an evening slot, 10–11pm EDT is relatively lower risk than earlier evening, but still has a 27% thunderstorm chance: travel only after checking updated alerts and confirming roads are clear. Postpone if storms or flooding persist, and never drive through floodwater.
