# Flash Flood Warning for Southeastern Nebraska Through 3:00 AM

**Cass, Gage, Johnson, Lancaster, and Otoe Counties, Neb. —** A band of slow-moving thunderstorms is wringing torrential rain over southeastern Nebraska late tonight, and the National Weather Service in Omaha/Valley has issued a Flash Flood Warning for southern Cass, northern Gage, northwestern Johnson, southeastern Lancaster, and Otoe counties through 3:00 AM CDT.

**What is happening:** Doppler radar showed thunderstorms producing heavy rain across the warned area just before midnight. Between 1 and 3 inches have already fallen, and rain is coming down at a rate of 1 to 2.5 inches per hour. Another 1 to 3 inches could fall before the night is over. Flash flooding is already underway in some spots and is expected to begin shortly in others.

**Local impacts:** Small creeks and streams will rise fast, and urban areas, highways, streets, and underpasses — plus other low-lying and poor-drainage spots — are at risk of flooding. Towns in the warning include Syracuse, Hickman, Weeping Water, Bennet, Elmwood, Firth, Adams, Palmyra, Cortland, Sterling, Unadilla, Panama, Avoca, Union, Clatonia, Roca, Hallam, Nehawka, and Pickrell.

**What to do:**

- Never drive through flooded roads — turn around, don't drown.

- Most flood deaths happen in vehicles, so do not try to cross water covering the road.

- Be extra careful after dark, when it is much harder to spot flood dangers.

- Watch your surroundings and keep clear of low-lying areas.
