An evacuation centre has been set up for people who were forced out of their homes at Oak Hills Trailer Park, which was under two to three feet of water.
The rain was a result of a small, but intense storm cell that passed over the area. Some Kamloops residents tweeted hail was falling during the storm.
The City of Kamloops says BC Hydro is on site and has shut off power to the trailer park to allow city crews to work in the areas. It also says culverts plugged by debris have been cleared.
Due to major congestion, drivers are being told to avoid Westsyde Road unless absolutely necessary.
