Key Factors
- 01 Flood Watch is active through late tonight; torrential rainfall of 2–3 inches per hour is possible, creating flash-flood risk in urban, low-lying, and poor-drainage areas.
- 02 Showers and thunderstorms are likely from 8 AM through early afternoon, with 58–75% hourly precipitation chances.
- 03 Thunderstorms remain possible through the afternoon, then become highly likely in the evening: 76–98% precipitation probability from 5 PM to 9 PM.
- 04 Forecast calls for 1–2 inches of rain during the day and another 1–2 inches overnight; some storms may produce heavy rain.
- 05 Visibility and road conditions are not provided, so localized flooding and reduced visibility may occur without being reflected in the hourly data.

Recommendation
Avoid nonessential driving, particularly from 8 AM–2 PM and 5 PM through midnight. If travel is necessary, the relatively lower-risk morning slot is 7–8 AM before storms become likely; there is no reliably safe evening slot, so postpone evening travel if possible. Never drive through flooded roads; monitor for Flash Flood Warnings and use a route away from low-lying or flood-prone areas.
