Rogers Pass Hwy 1, near Parks Headquarters at Glacier National Park, 72 km east of Revelstoke, looking east.

As southwest B.C. deals with its third atmospheric river in two weeks, bring more heavy rain and freezing levels above 3,000 metres, many of the mountain passes will also get soaked.

Environment Canada has issued special weather statements for the Trans-Canada Highway in the Rogers Pass and Fraser Canyon as well as Highway 5 between Hope and Merritt, which is currently closed.

Another frontal system is expected to bring rain to lower elevations and snow over Rogers Pass.

Snow levels are expected to rise to near 2,000 metres Tuesday night along with heavy rainfall on Wednesday, with rainfall amounts between 30 and 60 mm. There is potential for increased runoff due to snowmelt and the heavy rain on Wednesday, increasing the risk of flooding.

Environment Canada has also issued a special weather statement for the Fraser Valley, including Chilliwack and Hope, calling for a prolonged period of heavy rain today through Wednesday with between 60 and 90 mm expected today through Wednesday evening.

Environment Canada is predicting heavy rain, easing to periods of rain this afternoon and into tonight. The rain is expected to intensify again on Wednesday before tapering off late Wednesday evening as the system moves through the region.

Heavy downpours can cause flash floods and water pooling on roads. Localized flooding in low-lying areas is possible. Watch for possible washouts near rivers, creeks and culverts.

Environment Canada has also issued a wind warning for the Fraser Canyon south including Lytton, watch for
winds gusting to 90 km/h which are expected late Tuesday afternoon and tonight.
