Parts of Kansas are under multiple weather warnings for Monday, April 27, 2026, as the National Weather Service (NWS) warns of the potential for severe thunderstorms and rising water levels.
According to the NWS Storm Prediction Center, Severe Thunderstorm Watch 156 remains in effect until 10 a.m. CDT for much of eastern Kansas.
The watch includes counties such as Anderson, Coffey, Dickinson, Douglas, Franklin, Geary, Jefferson, Johnson, Leavenworth, Linn, Lyon, Miami, Morris, Osage, Shawnee, Wabaunsee and Wyandotte.
The NWS said atmospheric conditions are favorable for the development of severe thunderstorms across the region. These storms could produce damaging winds, large hail and isolated tornadoes.
The watch means severe weather is possible and residents are advised to stay alert and check for updates as conditions can change quickly.
Flood Warning for Osage County
In addition to the storm threat, NWS Topeka has issued a flood warning for Salt Creek near Lyndon in Osage County.
The NWS reported that at 7:17 a.m. CDT the water level in Salt Creek was 6.8 feet. However, levels are expected to rise significantly and exceed flood stage of 10 feet later in the morning.
Forecasts from the NWS indicate that the creek will crest around 12.3 feet in the afternoon and gradually drop below flood stage later in the day.
Expected impact
According to the NWS, flooding is expected to be minor, but could still affect low-lying areas, especially farmland near the Highway 75 bridge. At flood stage, water typically begins to spill into nearby fields.
Although major damage to infrastructure is not expected, localized waterlogging and road hazards remain a concern.
Security consulting
The National Weather Service urged residents to exercise caution. Motorists are strongly advised not to drive through flooded roads or around barricades as even shallow water can pose serious risks.
With the potential for severe storms and rising water levels, officials recommend staying informed about weather warnings and being prepared to take quick action if conditions worsen.
