Key Factors
- 01 Active Flood Watch for excessive rainfall today through late tonight, with flash flooding possible in poor drainage and urban areas
- 02 NWS alert states thunderstorms may produce very heavy rain, with localized 3-5 inches and rainfall rates up to 1 to 3 inches per hour
- 03 Hourly forecast shows thunderstorms likely or ongoing for much of the day, with highest precipitation chances from 2:00 PM to 7:00 PM (80-85%)
- 04 Daily forecast gives a 90% chance of precipitation during the day and 80% at night, indicating prolonged wet-road risk
- 05 Even outside the peak storm window, showers and thunderstorms remain possible from morning into late night, limiting reliably safe travel periods
- 06 Visibility data is not provided, so any storm-related visibility reductions or localized flooding impacts add uncertainty

Recommendation
If you must drive, the best morning window is 7:00-8:00 AM before storm chances increase. The relatively better evening window is 8:00-10:00 PM when rain chances decrease somewhat, but use caution and avoid flooded or poor-drainage roads. Avoid travel if possible from about 12:00 PM through 7:00 PM, especially 2:00-7:00 PM when storm and heavy-rain risk is highest.
