Torrential rainfall is looking likely overnight in spots of the Stateline, which means flash flooding may be a threat for residents late tonight and early Friday morning. A *Flash Flood Watch* has been issued until noon tomorrow to highlight where the worst of the rain may be overnight. The Watch is for Stephenson, Jo Daviess, Whiteside, and Carroll counties.
With the high amount of moisture in the air, coupled with the likelihood of strong, slow moving storms, these counties may see between 3" to 5" of rainfall tonight and early tomorrow. If the storms track over the same spots repeatedly, a few locations may see up to 7" of rain. This threat does extend into the rest of the Stateline through Friday, but the worst of the rain in the short term will be in the counties listed above tonight.
If flash flooding does occur, move away from rapidly rising streams and rivers, and head to higher ground. Do not drive into any flooded roads! Flash flooding is an underrated killer, because drivers underestimate how deep the water over the road is and can get swept away or stall in the flood waters. It does not take much water to float a vehicle off the road. If you see water over the road, find a different route.
