Recommendation
Driving is possible but exercise caution due to heavy rain and flash flood potential. Safer windows: morning around 7:00-8:00 AM (before storms intensify, POP ~19%), and late evening after 11:00 PM as storm coverage begins to taper (POP dropping to ~60%). Avoid the 5:00-10:00 PM window when storms and flooding risk peak. Never drive through flooded roadways.
