Update, 7:20 p.m. Monday:
Snow is expected to continue falling overnight in Anchorage and the Mat-Su, with between 3 and 8 inches of additional accumulation in the city before it begins tapering off Tuesday. Heaviest accumulations are expected along the Hillside.
Just as Anchorage is digging out from Saturday's record snowfall, forecasters are predicting another big storm has arrived.
This storm is expected to deposit 9 to 15 inches of fresh snow, on top of the 6 to 10 inches that accumulated Saturday in Anchorage, according to the National Weather Service.
"The way it's looking right now, it's going to be pretty messy by the late afternoon rush hour," said meteorologist Jason Ahsenmacher.
Light snow is expected through the morning but it is predicted to get heavy by afternoon, he said. The weather service has issued a winter weather advisory extending from 8 a.m. Monday to noon Tuesday. But light snow may continue until Wednesday, Ahsenmacher said.
As the snow began late Friday, it initially melted on the roads, then froze overnight as fluffy new snow fell, making for deceptively slick driving conditions, he said.
In the 24-hour period that ended midnight Saturday, Anchorage police counted 193 wrecks without injuries, 18 crashes with injuries, 20 hit-and-run wrecks and 56 vehicles in distress -- those that slid off the road or got stuck but didn't hit another car. After several crashes on the Glenn Highway, police began diverting traffic through Eagle River until road sanders could make a pass, according to police.
On Sunday, as snow was falling farther north, troopers reported a double-fatality crash near Mile 187 of the Parks Highway. Two trucks pulling trailers and heading in opposite directions crashed in the center of the road after one veered slightly over the center line, troopers said.
The 6.2 inches of snowfall measured Saturday at the National Weather Service office on Sand Lake Road topped the prior record of 4.6 inches for April 6, set back in 1949. The Hilltop ski area got an estimated 10 inches, while Joint Base Elmendorf-Richardson saw just 4 inches, though that measurement was as of 5:30 p.m. Saturday with snow still falling.
As of Sunday afternoon, the official Anchorage snowfall this winter measured 84.1 inches, which is more than a foot above average, Ahsenmacher said.
The coming storm is expected to center on Anchorage but reach north as far as Talkeetna and south onto the Kenai Peninsula.
