The National Weather Service in Omaha/Valley has issued a flash flood watch for a portion of southeast Nebraska and northwest Missouri, including Gage, Jefferson, Johnson, Pawnee, Richardson, Saline and Holt Counties. The watch is in effect from 7 p.m. Thursday evening through late Friday night.
Multiple rounds of heavy-rainfall-producing thunderstorms will impact the watch area beginning tonight (Thursday) and continuing into Friday night. Since the soil is already saturated from thunderstorms earlier this week, much of this new rainfall will runoff and create a flash flood threat. Excessive rainfall may result in flooding of low-lying or poor drainage areas, creeks and streams.
In addition to the flash flood hazard, rising river levels are also possible.
A Flash Flood Watch means that conditions may develop that lead to flash flooding. Flash flooding is a very dangerous situation. You should monitor later forecasts and be prepared to take action should Flash Flood Warnings be issued.
The Flood Warning continues for the Missouri River at brownville affecting Atchison and Nemaha Counties, and at Rulo affecting Holt and Richardson Counties.
