Recommendation
If travel is necessary, the safer window is early morning between 7:00-8:00AM (only 19% precipitation chance) before storms increase. Avoid driving from late morning through the overnight hours (9AM-midnight) when storm coverage and flash flood risk peak; if evening travel is unavoidable, wait until after midnight when precipitation chances begin to taper slightly, but flood watch remains active so exercise caution and avoid flooded roads at all times.
