A flash flood warning has been issued for Wyandotte County from 2:39 p.m. July 30 through 8:30 p.m. July 30, according to the National Weather Service.
The warning also is in effect in Leavenworth County and Johnson County, according to the weather service.
At 2:33 p.m., Doppler radar indicated thunderstorms producing heavy rain were moving into the area. Flash flooding is expected to begin shortly, the weather service said.
Residents are advised not to try to drive through flooded roads. Most flood deaths occur in vehicles, the weather service said.
Small creeks and streams, urban areas, highways, streets and underpasses will be affected, along with drainage areas and low-lying spots, according to the weather service.
Flood waters from the Missouri River could remain in Wyandotte County fields a little longer, as water releases have been stepped up from reservoirs upstream and rain is in the forecast for Kansas City and the river basin area.
With melted snow upstream entering the Missouri River basin area, the reservoirs upstream will be releasing more water into the river, according to Corps of Engineers officials.
The Corps of Engineers is stepping up water releases from the Gavins Point dam in South Dakota to 27,000 cubic feet per second today, and 30,000 cubic feet per second on Tuesday, Wednesday and Thursday, according to officials at a news conference today. This plan was changed from Sunday’s announcement.
There is currently major flooding on the James River upstream in the Dakotas, and water from the James and the Big Sioux rivers have an effect on the Missouri River.
A strong storm system is currently in the weather forecast from Thursday through Sunday, according to a National Weather Service forecaster.
About 1.5 inches of rain is expected to fall across northeast Kansas and northern Missouri, as well as some additional rainfall to the north.
If the rain falls as expected, some cities could receive 1.5 to 3 feet rises in the river, and the Missouri River at St. Joseph, Missouri, could rise 5 feet on Monday, according to the forecaster.
Thursday’s projected rain amounts will not show up in the National Weather Service river level forecasts until Tuesday, according to the National Weather Service forecaster, as there are only two days of anticipated precipitation included in each river level forecast. By Friday evening, the entire storm should be included in the river level forecasts, he said.
By the weekend, Corps officials and forecasters believe that the rivers will be substantially lower than they crested this past weekend. When the rivers rise next Monday, the main effect is that water will be on the levees for a longer time, according to Corps officials. With the longer time, the levees could become more susceptible to issues such as seepage or sand boils, according to officials.
