Key Factors
- 01 Flood Watch active through late tonight with NWS stating flash flooding possible and torrential rainfall (2–3 in/hr) in some storms.
- 02 High probability of showers/thunderstorms from late morning through the evening (POPs 60–98%), with the highest coverage this afternoon and evening.
- 03 Forecasted rainfall amounts of 1–2 inches (with heavy bursts) and guidance that excessive runoff may flood low-lying and urban areas.
- 04 No visibility data provided; this increases uncertainty about localized impacts (e.g., heavy rain reducing visibility), but high RH and thunderstorm wording imply reduced visibility during storms.

Recommendation
Avoid nonessential driving this afternoon and evening. Safer time windows (if travel is necessary and routes avoid low-lying/poor-drainage areas): morning: 07:00–08:00 local time (lower PoP ~19%); evening: no fully safe evening window today — if travel is unavoidable, choose 23:00–00:00 local time (lower but still moderate PoP ~60%) and avoid low-lying routes, do not drive through flooded roadways, and allow extra time. Monitor local alerts and flash flood warnings.
