Recommendation
Best morning driving window: 7 AM to 9 AM, before storm chances increase. Best available evening window: around 6 PM to 7 PM only if travel is unavoidable, but conditions are still deteriorating; avoid 2 PM through late evening if possible, especially 8 PM to 10 PM when storm chances peak and flooding risk is higher.
