Recommendation
If you must drive, the safest morning window is now through late morning, roughly 7:00 AM to 11:00 AM. For the evening, only consider driving after 9:00 PM if necessary, but conditions may still include showers; avoid travel from noon through late evening, especially during thunderstorms or if roads begin to flood.
