Key Factors
- 01 Rain showers likely from 8am to 2pm (about 40% chance of precipitation overall).
- 02 A chance of showers and thunderstorms from about 2pm to 5pm, which can bring sudden downpours and reduced traction.
- 03 Southwest/west winds are expected to be strong midday: about 8 to 21 mph with gusts up to 38 mph (gusts increase risk for high-profile vehicles and crosswind instability).
- 04 No visibility reduction data is provided; however, rain/thunderstorm periods can still significantly worsen road conditions despite the forecast not listing visibility explicitly.

Recommendation
If possible, avoid driving during the highest-risk window: 10am–3pm (highest combined rain/thunderstorm likelihood and strongest gusts). If you must travel, choose the safer periods around: morning 7am–9am (mostly cloudy to chance rain showers) and evening 7pm–9pm (mostly clear with very low precipitation chances).
