A series of late summer thunderstorms left a trail of damage across the National Capital Region.

Environment Canada issued two Thunderstorm Warnings/Watches and a Tornado Watch on Tuesday as severe weather moved through the region.

The storms dropped a record 30.2 mm of rain on Ottawa. The previous record for greatest rainfall in Ottawa on August 22 was 27.6 mm set in 2002.

The storms caused temporary flooding on Ottawa roads, knocked down trees and caused several scattered power outages across the region. The Airport Parkway was littered with trees and braches.

Ottawa’s CFB Uplands was one of the hardest hit in the area, with 15 to 20 trees up-rooted from its base.

During heavy rain on the afternoon commute, a tree fell on a car along Queen Elizabeth Drive at Fifth Avenue. The occupant of the car was not hurt.

The CP Women’s Open at the Ottawa Hunt & Golf Club was forced to clear the course during the practice round for this weekend’s tournament.

Environment Canada says there are indications a tornado caused damage in Lachute, Quebec just after 6 p.m. The storm damaged several homes, ripping a roof off one structure. Trees were uprooted or broken, and porches and fences were damaged. Environment Canada investigators will be on the scene Wednesday to confirm whether the damage was due to a tornado.
