Recommendation
Avoid driving between 12pm-8pm today when thunderstorm activity is heaviest and flash flood risk is greatest. If driving is necessary, travel before 8am when conditions show only 5% precipitation probability and no flood risk, or wait until after 9pm when thunderstorm risk decreases to 32% and activity is diminishing.
