— The National Weather Service has issued several watches and warnings for possible snow accumulations across the region this weekend.

A winter storm watch is in effect from midnight Sunday until noon Monday for the Methow Valley and Conconully.

Meteorologists said they expect 5-to-12 inches of snow accumulation in the valleys and 7-to-15 inches in the mountains.

“Light snow will develop late Saturday night and increase in intensity through the day on Sunday,” said a statement from the service. “The snow is expected to change over to rain and freezing rain Sunday night into Monday morning.”

The service said ice accumulation and snow-covered roads may make for dangerous travel.

“Snow-covered roads will make for hazardous travel on Sunday,” the winter storm watch said. “Freezing rain Sunday night may lead to ice on area roadways and power lines.”

Leavenworth, Stehekin, Blewett and Loup Loup Pass are under the same watch.

The snow level is expected to rise to between 5,000 and 7,000 feet south of Lake Chelan by Monday morning, meteorologists said.

A separate, hazardous weather outlook was issued Friday morning, continuing through Thursday for several counties including Okanogan and Ferry.

The hazardous weather outlook also includes Grand Coulee, Coulee City, Waterville plateau, the Wenatchee area and Moses Lake.

“Confidence is high that a winter storm will arrive in the region Saturday and last through Monday,” the outlook statement from the weather service said. “This will bring heavy snow accumulations to the mountains and possibly to the valleys.”

The services predicted up to 1 inch of snowfall in Inchelium, Republic and Wauconda.
