Juneau, Alaska, Buried In December Snow, Now Faces Rain, Flooding, Avalanches

weather-beleaguered city

In December, Juneau, Alaska was buried under more than 80 inches of snow, capsizing boats in the harbor, caving in roofs and blocking streets. 

Now, after some more snow, it's raining up there in Juneau. Now we have an even bigger mess.

Juneau sometimes gets heavy snow and downpours of rain during the winter as storms and atmospheric rivers come in off the Pacific Ocean. 

But the extremes of the past few weeks is totally off the charts compared to what Juneau has experience in the past 

"These are unprecedented times," said Aaron Jacobs, the senior hydrologist at the National Weather Service office in Juneau.  "The amount of snowpack that we are seeing on the ground at the airport, and then this massive warm-up we're seeing, really hasn't been seen in the climate records."

After four additional inches of snow fell on Juneau Friday, the precipitation switched over to rain. The city received 1.58 inches of precipitation that day. Areas around Juneau receive up to eight inches of snow and two inches of rain.  

On Friday and over this weekend, the rain/snow line crept up the steep slopes of the mountains. The higher up the slopes the rain gets, the greater the avalanche risk.

As KTOO reported:

"John Bressette, the city's new avalanche advisor, said multiple avalanches happened on Mount Juneau on known slide paths including White Pass, Chop Gully near Flume Train and above Behrends Avenue. He said he doesn't know exactly how many occurred, but that it's somewhere in the double-digits." 

People in avalanche prone areas in and near Juneau were urged to be ready to leave at the drop of a hat due to the avalanche worries. 

An emergency warming shelter was moved from a converted warehouse to an elementary school Friday due to the avalanche risk. By Sunday, emergency managers deemed that the avalanche risk had diminished, so they moved the shelter back to the warehouse.  There could be avalanches in that areas, but they wouldn't be strong enough to reach the shelter. 

Some avalanches did crash down the steep slopes above Juneau, but none hit populated areas. 

The shelters are open in large part because the weight of the snow, plus the rain water soaking into that snow, is threatening the stability of many roofs in and around Juneau. 

About sixty people were on the roof of the Bartlett Regional Hospital Saturday trying to remove snow because roof loads were nearing capacity, reports KTOO.

The snow-clogged storm drains and ditches in Juneau were no match for the rain and the snow melt. Streets flooded, and water began to seep into basements across the city. 

Another rain storm was set to hit Juneau and the rest of southeast Alaska last night and this morning. A more powerful storm set to hit Tuesday night has prompted a flood watch for southeast Alaska, especially south of Juneau. To add insult to injury, a  high wind watch is also up for Tuesday night and Wednesday for pretty much the entire Alaska Panhandle.
