The Federal Government has designated the Chilkoot as a national historic trail. Gaining fame during the Klondike Goldrush, the Chilkoot was a major thoroughfare into the interior of the Yukon and Alaska. Prior to that, the trail was a major route for the Native population for a millennia.
Currently, the Chilkoot is closed due to major trail damage from flooding this past autumn. A series of atmospheric rivers pummeled the area, The Taiya River reached flood stage on five different occasions during a two month period last fall, eroding banks and dislodging bridges along a large section of the trail, that follows the river.
There is hope that the trail will be open at some point this summer. The complete trail to Bennett Lake has not been open due to Canadian restrictions since the start of the Corvid pandemic. There is also hope that those restrictions will also be lifted for the upcoming hiking season.
…still packed quite the punch.
The western coast of Alaska was pummeled over the weekend by the remnants of Typhoon Merbok. Sustained winds over 50 mph, with gusts over 90; 50 foot waves and a storm surge 15 feet above high tide left many evacuating to higher ground.
It was the worst storm our Western Coast has experienced in 50 years, and it has been 70 years since a storm this fierce hit in September.
To its credit, The National Weather Service was remarkably accurate in its forecast of the storm. Several days out, the NWS was getting out the word that this was going to be a devastating flooding event. All the ingredients came together perfectly to create some “very angry seas”.
High winds have taken roofs off of buildings, one building in Nome suffered from a fire, and the storm surge has evicted hundreds. Many took shelter in schools, or to higher ground.
My favorite village of Newtok has been flooded, and many have taken to the school for shelter. The riverbank at Newtok has eroded between 10-15 feet overnight. Newtok is one of several villages in Alaska in dire need of relocation due to erosion and sinking ground.
Water levels in many flooded villages are not expected to drop until Monday, and in some cases Tuesday. The timing of the storm is particularly difficult, with winter on the horizon. The village of Shaktoolik lost its sea berm to the storm, which leaves it vulnerable to additional winter storms. The village of Chevak lost much of its fishing fleet when boats sank or were damaged in the storm.
We really have two seasons in Alaska: Winter, and Preparing for Winter. Preparing for winter in Western Alaska is now going to be a huge challenge.
The Lower 48 remains caught up in the heat of summer, but autumn has taken hold in Alaska. The seasonal graphic that AlaskaWx puts together is a review that I always enjoy, so I’m sharing it here.
Weather-wise, Alaska was all over the map this past summer. Fairbanks had one of our driest summers on record, while Anchorage had a top three driest June, only to then see a top three wettest August.
Toolik Lake had snow in July, while Denali Park saw the white stuff accumulate in August.
The Southeast had an early heatwave, and Cold Bay saw a record early first freeze.
Overall, Alaska has seen 3.11 million acres burn to wildfire, which is the seventh largest burn season since 1950.
No one was surprised to hear the National Weather Service issuing flood watches and warnings throughout Alaska’s Interior this past weekend. With a Top Ten Snowfall this past winter, we have been readying for the coming melt.
Manley Hot Springs is one of the first communities to come under water. An ice dam on the Tanana River has caused water to back up into Manley. As of Sunday morning, as many as 75 residents in the lower areas of the town had been displaced, many of which were seeking shelter in the Manley Hot Springs Lodge.
Reports have ice starting to move on the Tanana, which would alleviate the flooding.
A Flood Watch had been issued for Eagle on the Yukon River, as well as Hughes on the Koyukuk. Ice now appears to be moving on both rivers and those two watches have been cancelled as of Sunday afternoon.
Temperatures for the coming week are going to dip down into the low to mid 40’s F for highs, with a (relatively) rare chance of May snow for Fairbanks. Even though we are all ready for summer and its warmer temps, a slow melt would be a good thing.
Over the past five decades, Alaska has seen a substantial increase in precipitation. The Southeast & South-Central part of the state has seen only single digit increases, which is probably a good thing considering much of that area is a rain forest.
Interior Alaska has seen a 12% increase in precipitation. I can’t say I’m surprised by that, as we definitely seem to be getting more snow during the winter. With a warming trend, we were bound to see more snowfall.
Still, it’s intriguing to see the actual numbers.
As forecast, a Chinook blew into Interior Alaska this past weekend, driving temps in Fairbanks up into the 40’s. It was +44F at 8am in the valley on Sunday morning. The average high on Halloween is +18F. Also, as expected, our dusting of snow became a few patches of white.
Further south in Alaska: The NWS station in Girdwood at Alyeska recorded 9.5″ of rain in a 24 hour period. Nearby Porter Glacier Visitor Center recorded 10.34″ of rain on Saturday. It is the first 10+ inch precipitation event in 24 hours in Alaska since 2012. The storm total at Portage Glacier was 17.72″, as of Sunday evening. The epicenter for this event is Mount Baker, which is just 75 miles east of Anchorage, but 13,000 feet higher. The forecast for the slopes of Mount Baker “Snow could be heavy at times”. SATURDAY AFTERNOON: 29-35″; SATURDAY NIGHT-SUNDAY MORNING: 108-114″ Possible; SUNDAY AFTERNOON: 82-88″; SUNDAY NIGHT: 100% Chance of Snow, Heavy At Times.
Wildfires within Alaska burned less than half the usual acreage in 2020, which is not really a surprise with an unusually wet summer.
Fairbanks had its 12th warmest and 20th wettest summer in the past 90 years.
Anchorage saw its 23rd warmest and 28th wettest in the past 70 years.
Juneau had its 10th warmest and 15th wettest in the past 81 years.
The western coast of Alaska was just plain wet.
Bristol Bay had some very rough seas during the fishing season, but that didn’t keep them from setting a record year for sockeye salmon.
The Yukon River drainage had no salmon in 2020. No chums. No kings. Nada. The entire fishery was closed.
One bright spot was the amount of sea ice in the Chukchi Sea in August. It was the most we have seen in 15 years.
Denali National Park has already seen 6″ of the white stuff.
Fairbanks has already seen frost.
Friday morning at the Eielson Visitor Center, Denali National Park. Elevation: 3300′.
In another weather note: As of Friday evening, Fairbanks has seen 175% of normal rainfall for the entire month of August. That puts us at the 8th wettest August since 1930, although both 2018 and 2019 had more rainfall at this point than this August.
The Tanana Valley State Fair started on Friday, which generally means the slippery slope towards winter is well underway. With Alaska’s size, each corner of the state has its own fair, as opposed to just one for the entire state.
The start of the Tanana Valley State Fair is known for the start of the rainy season. In fact, a booth at the fair gives away prizes for the guessing how much rain Fairbanks will get during Fair dates.
This year, that number is looking to be unusually low. No rain is in the forecast until the fair’s final days, which means attendance could be good after not having one last year. Although, I have heard from many people that they will sit this one out, due to the rise in Covid cases. Time will tell on both fronts.
We are looking at a very warm week here. Not Texas hot mind you, but mid to upper 80’s, which is definitely warm for Interior Alaska.
