18 ft. of snow in Alaskan town

Seems much of the precipitation is staying north for now. but, what if this were to happen over an area like chicago or new york?
that is a lot of snow, and then for it to get weighed down by rain in January seems very unusual for Alaska.

Alaska town tries to dig out from huge snow dump

ANCHORAGE, Alaska (AP) -- Dozens of National Guard troops have arrived in Cordova to help the Alaska fishing town dig out from massive snows that have collapsed roofs, trapped some people in homes and triggered avalanches.
The city is used to snow, but not like this season's blanketing.
The Guard reported more than 18 feet of snow has fallen in the past weeks, although the National Weather Service did not immediately have a measurement.
"There's nowhere to go with the snow because it's piled up so high," said Wendy Rainney, who owns the Orca Adventure Lodge. A storage building for the lodge - which offers fishing trips, hiking, kayaking and glacier tours - partially collapsed under the weight of the snow, she said.
"This is more quantity than can be handled."
At least three buildings have collapsed or partially collapsed and six homes are deemed severely stressed by heavy wet snow, officials said.
The drifts are 12 to 14 feet high, but most roofs in town have been shoveled, said Chris Dunlap, a Cordova resident who was manning an empty Red Cross shelter early Monday.
"It's a lot of snow. I've lived here 33 years and this is the most snow I've ever seen," she said by phone. "The thing I'm impressed most with is we haven't had any injuries. Maybe a few back strains from all of the shoveling. But we have a very, very efficient, professional emergency staff here."
The city has set up a shelter at a local recreation center but said people leaving homes in avalanche-risky areas have been staying with other residents. Cordova spokesman Allen Marquette said the town also was ready to set up a pet shelter if necessary.
The town issued a disaster proclamation last week after three weeks of relentless snow overwhelmed local crews working around the clock and filled snow dump sites.
"We had no alternative but to declare an emergency," Cordova Mayor Jim Kallander said. "It became a life-safety issue."

Indeed. Here is a similar story on SOTT: https://www.sott.net/articles/show/240076-US-Alaska-town-tries-to-dig-out-from-huge-snow-dump
 
This is a pretty serious snow for structural snow loaded conditions. Indications are that roof structures in Alaska to code are 50 psf as a minimum and winter snow loads in some parts can reach 300 psf. In many places in the world structures are built to only 20 – 40 psf; some way less.

That being said, if at 18 ft accumulations (which will compact), but still using 18 ft though for this purpose - @ 7 pounds per cubic ft (light snow) = 126 psf or up to 30 lbs per cubic ft (older snow) = 540 psf (which is already over the top).

If that snow takes on rain or further snow accumulations it will get very dangerous. :( Be careful if you live there.
 
"By one count, more than 10 feet of snow has fallen in the town of 2,000 in the last few weeks."

10 feet not 18 feet

Then down farther it says:

"This winter, almost 15 feet of snow has fallen on Cordova,..."

Different tape measures?

It is still a lot of snow.
