PORTLAND -- Gusts combined with falling and blowing snow will create low visibility and blizzard conditions in the Cascades Friday, with a winter storm warning in effect through late Saturday afternoon.
Snow levels will be around 2,500 to 3,000 feet Friday, according to the National Weather Service.
In lower elevations, expect morning showers turning to heavy rain late Friday morning, said KGW meteorologist Nick Allard. Expect several inches of rain at the coast and up to an inch in the Portland area and valley.
"Fifteen to 25 inches of new snow are likely at Cascade ski areas from Friday through Saturday morning," said KGW Chief Meteorologist Matt Zaffino said. "An Avalanche Watch is also up for the Cascades as the new snow will make back-country conditions dangerous"
"The snow level will bottom out around 1,000 feet Saturday," Zaffino said.
Zaffino said rain and mountain snow was expected to return Sunday night and Monday with the snow level hovering around 2,000 feet.
