Key Factors
- 01 No active weather alerts are listed, but the forecast explicitly says some thunderstorms could be severe and produce heavy rain.
- 02 Rain chances are lower in the morning (about 16% to 23%) and increase from midday onward with thunderstorms developing.
- 03 Highest-risk period is late afternoon through evening, especially about 18:00-21:00 local time, when precipitation chances rise to roughly 52% to 60% and thunderstorms are likely.
- 04 Heavy rain can reduce visibility and increase hydroplaning risk, especially after dark.
- 05 Winds are light, so the main hazard is thunderstorms and heavy rainfall rather than wind.

Recommendation
If you need to drive, the safer morning window is about 08:00-11:00 local time. For evening travel, the relatively better slot is after 22:00, but use caution because showers and thunderstorms may still linger; avoid driving if possible from about 12:00-21:00, especially 18:00-21:00.
