Forty-eight hours of torrential downpour in an atmospheric river event has left hundreds forced out of their homes due to extensive flooding.

Environment Canada estimated 50 mm to as much as 150 mm of rainfall in parts of southern B.C. on Monday (Nov. 15).

Evacuation orders have been issued for Merritt and parts of Princeton, two cities located in low flood plains which saw the brunt of localized flooding. Evacuation orders and alerts have also been issued for Abbotsford, Chilliwack and Squamish.

Highway 1, 3 and 7 all remain closed due to the flooding, with several mud and rock slides reported along the routes connecting the Lower Mainland and Interior B.C.

It鈥檚 unclear how many were able to be rescued Monday, but some reporting on social media that their loved ones have yet to be heard from. Black Press Media has reached out to the ministry for an update on rescue efforts.

Public Safety Minister Mike Farnworth said in a news conference Monday that the situation continues to be 鈥渄ynamic,鈥� with efforts focused on assessing damage and assisting evacuees. The remaining people stuck are expected to be rescued by end of day, he said.

Although rainfall warnings have been lifted for much of southern B.C., meteorologists are calling for an evening of windy storm conditions in Lower Mainland, Vancouver Island and parts of the Okanagan before the weather appears to be shaping up into sunnier conditions for Tuesday.
