Recommendation
Avoid driving from now through at least 10:00 AM EDT, and use extra caution until 12:00 PM EDT because flooded roads may linger after the warning expires. Safer morning slot: 11:00 AM-12:00 PM EDT if roads are clear locally. Safer evening slot: 6:00 PM-9:00 PM EDT, when the forecast is dry with light winds and improving visibility. Do not drive through flooded roadways.
