Severe thunderstorms that rolled through the Kansas City metropolitan area on Sunday evening left tens of thousands without electricity, downed power lines and prompted emergency responses across both sides of the state line.
Widespread outages, damage reported
According to the Evergy outage map, roughly 35,000 customers were without power Sunday night in pockets from Kansas City, Missouri, south through Cass County. The Kansas City Board of Public Utilities reported an additional 676 customers without power following the storms.
Local authorities in Cass County reported fallen trees and limbs that struck power lines in residential neighborhoods. The Raymore Police Department said power lines were down in some areas of the city. In Harrisonville, the city posted that storm damage to transmission lines outside of Pleasant Hill contributed to outages that affect the community’s power grid.
"Evergy has informed City staff that their transmission lines outside of Pleasant Hill were affected by the storms that rolled through Cass County. These lines feed our power grid here in Harrisonville and are what has caused the outages you have experienced," the city wrote on Facebook.
Public events and emergency responses
Organizers of the Kansas City Irish Fest closed the festival grounds before 8 p.m. as severe storms approached downtown Kansas City. In a social media post, festival organizers urged patrons to remain sheltered and later announced the event would not reopen for the night, saying, "see you next year."
The Kansas City, Missouri, Fire Department responded to damage at a building located at 115 NW Harlem Road, where crews found part of an existing rain roof had been blown off. No injuries were reported in connection with that response.
How communities were affected
Impacts reported across the metro included:
- Downed power lines and tree limbs across neighborhoods in Cass County, Raymore and Harrisonville.
- Event cancellations and evacuations — notably the early closure of Kansas City Irish Fest.
- Localized structural damage, including a partial roof blown off a building in Kansas City.
Emergency management and utility crews typically prioritize hazards to life and safety — such as downed live wires — followed by restoring service to critical facilities and then clustered residential outages. The city of Harrisonville cautioned residents that brief interruptions could occur as Evergy crews work to complete repairs.
| Utility | Customers without power | Primary areas affected |
|---|---|---|
| Evergy | ~35,000 | Kansas City (Mo.) through Cass County, including Raymore and Harrisonville |
| Kansas City BPU | 676 | Kansas side of the metro |
Weather advisories and response
The National Weather Service office in Pleasant Hill issued a Severe Thunderstorm Warning Sunday afternoon covering a broad portion of western Missouri and parts of southwest Iowa; that warning later expired. City and utility officials urged residents to avoid downed power lines, stay indoors while severe weather passed and to report outages through their utility’s official channels.
Information about restoration timelines and safety advisories typically comes from the utilities; residents in affected areas are advised to monitor Evergy and Kansas City BPU social media pages and outage maps for updates. Where roads are blocked by trees or debris, motorists should use caution and expect delays as crews work to clear hazards.
WE NEWS will continue to monitor official updates from Evergy, the Kansas City Board of Public Utilities and local emergency management for restoration timelines and safety information.
