At 400 AM CDT, local law enforcement reported that water levels 
remained high in many areas with several road closures. While most

Coffeyville, Independence, Cherryvale, Caney, Dearing, Elk City,
Tyro, Liberty, Havana, Bolton, Sycamore, Elk City Lake, Elk City

Move to higher ground now. This is an extremely dangerous and
life-threatening situation. Do not attempt to travel unless you are
fleeing an area subject to flooding or under an evacuation order.

Turn around, don't drown when encountering flooded roads. Most flood
deaths occur in vehicles.

Be especially cautious at night when it is harder to recognize the
dangers of flooding.
