Recommendation
Avoid nonessential driving, especially this afternoon and evening, and never drive through water-covered roads. If travel is necessary, the relatively less hazardous windows are 7:00–8:00 AM in the morning and 2:00–4:00 PM in the evening/daytime; storms remain possible in both windows, so check for updated warnings and reassess before leaving.
