Key Factors
- 01 Flood Watch in effect 2:13AM-until late tonight for flash flooding from intense rainfall (2-3 in/hr possible)
- 02 Precipitation probability rises to 87-93% from late morning through evening, with thunderstorms likely, some potentially severe
- 03 Smoke present through the day, likely reducing visibility, compounded by Air Quality Alert (code orange) for sensitive groups
- 04 Wind gusts up to 24-26 mph possible, adding crosswind risk especially near storms
- 05 Showers/thunderstorms continue into the evening and overnight, with continued flood risk

Recommendation
If travel is necessary, the safer window is early morning before 8AM (lower rain chance ~15-49%, though smoke may still limit visibility). Avoid driving from late morning (10AM) through the evening and into the night when thunderstorms, flash flooding, and severe storm potential peak. If evening travel is required, wait until after midnight when precipitation chances drop to around 55% and diminishing, but road flooding may still be present.
