A swift and intense storm system brought heavy rainfall to Emporia and west central Lyon County late Wednesday night into Thursday, leading to a flash flood warning across the region.
This isolated, slow-moving storm system produced 1.4 to 1.7 inches of rain in a very short time, overwhelming drainage systems and triggering hazardous road conditions.
The most impacted locations saw road closures, vehicle rescues, and rapid street ponding, although thankfully, no injuries were reported. The situation developed quickly, leaving many residents and travelers to adapt to dangerous conditions.
Rainfall Totals and Impacted Areas
The sudden storm caused highly variable rainfall across regions, with some areas more severely affected than others.
Rainfall and Area Impact – April 24, 2025
| Location | Rainfall (Inches) | Impact |
|---|---|---|

| Emporia West Plaza Parking Lot | N/A | Vehicle water rescue carried out safely |

These rapid rainfall amounts led to urban drainage systems exceeding their limits, especially in low-lying and underpass areas.
Road Closures and Emergency Actions
A few key areas in Emporia were immediately affected:
- Mechanic Street Underpass was shut down due to flooding and water accumulation.
- Kansas Highway 99, specifically near the 1300 block, experienced water flowing over the road.
- Emergency responders were called to assist in a vehicle water rescue at Emporia West Plaza. The car was successfully moved, and no injuries occurred.
Although nearby river gauges responded to the rain, levels stayed safely below flood stage, avoiding broader waterway-based flooding.
Hail and Storm Intensity
While Emporia experienced primarily rainfall, Osage County had a more intense storm the night before, with up to 2.5 inches of rain and hail measuring up to 1.25 inches in diameter. The back-to-back weather events further saturated the region’s soil, increasing flood risk.
