A downburst has been confirmed in Chatham, after a storm on May 16, 2025.
The The Northern Tornadoes Project (NTP) confirmed, following a damage survey and thorough radar analysis, that an EF0 downburst occurred near Chatham in southwestern Ontario.
“Though there was significant damage to several structures it was determined that downburst winds to only 130 km/h were experienced – resulting in a rating at the high end of EF0,” NTP officials say.
“Similar downburst damage was reported in several other locations, from Windsor west of Chatham to Shrewsbury east of Chatham. Only this area of enhanced damage near Chatham was surveyed, however.”
The time of the event was 2:15 a.m.
“Damage to several barns and farm buildings, power poles and trees was reported south of Chatham after a storm passed through the area,” NTP officials added.
“An NTP ground and drone survey was completed on May 16, 2025, documenting the reported damage and additional weak damage in the area. Damage assessed as EF0 downburst, with an estimated max. wind speed of 130 km/h, with intermittent damage found over an area approximately 9.0 km long and up to 1.5 km wide. Start time is radar estimated. Satellite imagery review is pending.”
No injuries were reported, NTP officials added.
