During the Storm

• Stay home if possible. Avoid unnecessary travel; wet and flooded roads can be dangerous and can prevent you from getting to your destination. Staying home is the safest option until the storm passes. If its an emergency, allow emergency responders to come to you.
• Drive carefully if you must go out. Go slow, keep headlights on, watch for obstacles, and leave extra space between vehicles. 
• Turn around, don’t drown. Never attempt to walk or drive through standing water. Do not drive through flooded areas or around barricades.
• Stay clear of downed power lines. Treat all fallen power lines as live; call 9-1-1 to report them.
