At 12:30 p.m. Saturday, the Allen County Highway Department reports water over many of the county's highways, particularly in the southern and eastern sections of the county. These conditions are expected to continue through the weekend. Though some of the roads may be passable, motorists should use extreme caution and avoid driving through flooded roadways -- even if there are no warning signs visible. According to the National Weather Service, most flash flooding deaths are vehicle related. Six inches of standing water is enough to cause passenger cars to stall and a foot of water will float many vehicles. Again, motorists should never drive through flooded roadways, especially if the water is moving rapidly, and never drive around the barriers warning you that the road is flooded.
