Flooding is one of the deadliest forms of weather in Nebraska. A woman is still missing from Lincoln after being swept away by flash flooding there in 2015. And even places that don't receive significant rain can be subject to deadly flooding. An elderly southeast Nebraska woman drowned in 2015 when upstream heavy rains swamped her riverside home.

Periods of heavy rain are expected through Wednesday evening, according to the weather service. About 1 inch to 2 inches is forecast, but more could fall in areas where thunderstorms occur.

The area at greatest risk is along and south of Interstate 80 in the southeast corner of the state. The flood risk extends south into Kansas and Missouri.

Additionally, the Missouri River at Brownville and Rulo is expected to rise to moderate flood stage in the days ahead.
