Inland Flood Impact: HIGH

Widespread Dangerous Flooding Possible

Flash Flood Warning will be issued. Observational data indicates that ongoing or imminent heavy rain is sufficient to produce rapid flash flooding in the next 1 to 4 hours. The rule of thumb is 4 inches/ 1 hour and/or 4 to 6 inches for 2-6 hours. Persons living near or in poor drainage locations should prepare for possible evacuation. In these areas, significant property damage will occur, and some power outages are likely. Minor property damage is possible elsewhere.

Water levels in very poor drainage areas will approach 7 feet. Other poor drainage locations will have rises to between 3 and 5 feet. Elsewhere, expect water rises to near 2 feet. Numerous main roads will be closed. Driving is highly discouraged except in emergencies.

All rivers in affected areas will rise, with some reaching or exceeding flood stage. Normally quick rising rivers will exceed flood stage by several feet, flooding homes along the shore. Pastures will also flood, but livestock losses should be minimal. Several secondary roads and bridges will be washed out.
