A slow moving cold front along with an upper level low pressure system caused scattered showers Tuesday morning, May 1. Showers started to develop around 2:00am in Pottawatomie County and remained in the area for several hours. At least four inches of rainfall was seen by 9:00am, causing flash flooding of intersections and country roads as well as farmland along the banks of creeks and streams. The National Weather Service then issued a Flash Flood Warning for Pottawatomie County at 9:00am until 1:00pm.

At 9:10am, law enforcement reported water flowing over Highway 24 in Westmoreland. Flush Road at Highway 24 was closed where traffic was impeded by the overflow. By 10:00am, residents of Louisville were prepared to evacuate their homes in the event of Rock Creek flooding. At 10:45am, an emergency manager reported water flowing over K18 just west of Zeandale, southeast of Manhattan. Deep Creek was also reported out of its banks near Zeandale in Riley County.

The National Weather Service issued a Flood Advisory for Riley County from 11:15am until 1:15pm as doppler radar indicated very heavy rain had fallen over the area. The NWS also issued a Flood Warning for Rock Creek near Louisville at 12:00pm, anticipating minor flooding. During a Flood Warning, drivers are urged to avoid flooded areas as shallow flowing water can wash a car from the roadway. Also, roadbeds may be washed out.

I received a phonecall around 12:30pm from Barbara who lives five miles south of Westmoreland. She reported about 12" of rainfall had fallen at her location! She said the roads had flooded earlier but were beginning to improve as the rain tapered off.

At 1:00pm, the National Weather Service allowed the Flood Warning for Pottawatomie County to expire. By 12:45pm, flood waters had receded and the threat for additional flash flooding had ended at that time.

At 1:15pm, the National Weather Service allowed the Flood Advisory for Riley County to expire. At 1:00pm, doppler radar indicated the heavy rain had ended and the high water had receded.

This is a graph of the rain totals provided by the National Weather Service:
