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.
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.
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.
National Park Week, Day VIII; Today’s Park Theme: Junior Ranger Day
The “Hottest, Driest and Lowest”:
I have been lucky enough to visit Death Valley a few times. I did skip this Park when I was traveling in the air-cooled VW, but the Land Rover has been here a couple of times, and I once tortured a rental car during a visit to Death Valley in August. I drove the rental here from Las Vegas after a wedding just to see how hot it would get. I watched the car thermometer hit +123F. So my personal variance is -63F to +123F degrees.
It was not over 100 when I drove the Rover through. In fact, I remember it being quite nice, weather-wise. Very cool at night, and above 80F during the day. At one campground, it absolutely poured rain. Gullies filled quickly, but I had the rooftop tent. I could see the rain coming across the desert from my site, and quickly popped open the tent, threw what I needed up into it, then set up a chair under the canopy to eat dinner. The rain came down in buckets, and the wind picked up, so I moved my chair into the back of the Rover, and watched the proceedings. Across the campground, I could see two poor souls battling a ground tent. They should have just waited out the rain, but they stuck to their guns, and kept on with the tent. It took forever, to the point that I was suffering just watching the show. The tent had to be as soaked inside as they were standing out in that downpour.
Death Valley was first established as a National Monument in 1933, becoming a National Park in 1994. The Park encompasses 3,373,063 acres across the states of California and Nevada. Badwater Basin, which I have done some hiking in, is the second lowest point in the western hemisphere at 282′ below sea level. Telescope Peak is the Park’s highest point at 11,049 feet above sea level.
The Valley is a hot and dry place to explore, so bring plenty of water. Hot weather tip: Any water jug left in your vehicle will quickly reach the temperature of the vehicle’s interior. So, if you don’t want to brew a cup of tea after a day out hiking, try to keep that jug outside and in the shade.
The highest temperature ever recorded on Earth happened at Furnace Creek in Death Valley in 1913: 134F. That is a scorcher. The record low for Death Valley is 15F. Practically balmy when you think about it. Badwater gets on average 1.5 inches of rain a year.
I did stop by Scotty’s Castle on one visit. It was named after a local gold prospector, Walter Scott, who neither lived in, nor built, the residence. Construction began in 1922, and the building costs were somewhere between $1.5 – 2.5 million. The history here is intriguing, and involves investments in nonproductive mines, as well as mistakenly building on government property. The stock market crash of 1929 also played a part. When the owners passed away with no heirs, the National Park Service bought the “castle”. It can be toured, during non-covid years, and I thought the tour was well worth the fee.
The castle’s water source was a nearby natural spring, which also powered a Pelton wheel which powered the house as well. Death Valley Scotty may not have lived in the castle bearing his name, but he is buried on a hillside overlooking the home. The family’s pet dog is buried next to him.
There is so much to see at Death Valley. The famed Racetrack is one location, but I did not witness any racing rocks, still it’s a phenomenon that is cool to document. The Eagle Borax Works, or more commonly known as the Twenty Mule Team of Borax fame has some ruins out in the Park, and there are several CCC works still being used. There are trails, and wildflowers galore when it rains, natural springs and arches, and petroglyphs out at Mesquite Springs.
This summer, Fairbanks has seen its 7th wettest since 1925. With 12.6″ of rain recorded as of last Friday, climatologists tell us that we are on a new trend. The typical summer rainfall is now 30% higher than in the 1920’s-1930’s. Juneau also saw its 6th wettest summer in 96 years. That’s saying something about our very wet capital city.
Fairbanks also had 19 days with thunder, which tied a record. We were 3.6 degrees warmer than average, which puts 2020 in the Top Ten, since recording began. Much of the change came in the rise of nightly low temperatures, due to the rain and cloud cover.
Officially, Fairbanks had a growing season of 130 days in 2020. That ties us for the 7th longest. Since 1950, the growing season in Fairbanks has increased by 16 days.
Wildfires burned a total of 181,000 acres in Alaska for the season so far. That is the lowest total since 2002. For one season, at least, wildfire crews did not have to worry about hotshotting into the Alaskan Bush. They have more than enough on their plate, as it is, in 2020.
Dall Sheep, Ovis Dalli dalli, can be found throughout Alaska’s mountain ranges. Dall Sheep prefer relatively dry country, their territory is the open alpine ridges, mountain meadows and steep slopes. They like to keep an extremely rugged “escape terrain” close at hand, and are not often found below tree line.
The rams are known for their massive curling horns. The ewes have shorter, more slender and less curved horns. The males live in groups and seldom interact with the females until breeding season, which is in December.
Lambs are born in late May to early June. Ewes usually reach breeding age at 3-4, and have one lamb each year after that. The lambs are most vulnerable during their first 30-45 days of life, and mortality rate is high during this time. Wolves, black & brown bears and golden eagles are the main predators.
Dall sheep horns grow steadily from early spring to late fall, but tend to slow, if not stop growing altogether, during the winter months. This leaves growth rings on the horns called annuli. These growth rings can help identify the age of Dall Sheep. In the wild, 12 years of age is considered old for a Dall Sheep, but rams have been identified as high as 16, and ewes up to 19 years of age. A Dall Sheep ram can weigh up to 300 pounds, with the ewes being about half that weight.
Between 1990 – 2010, Dall Sheep numbers had dropped by 21%, from 56,740 to 45,010. Numbers started increasing up until 2013, when a later than average snowfall put a damper on recovery efforts. Dry, heavy snow loads appear to have little effect on sheep population, but the heavy, wet snowfalls, with a frozen crust can make foraging and travel difficult. Freezing rain has also become more prevalent. All of these factors contribute to more avalanches, which have become a significant cause of death for Dall Sheep in the state.
2019 is already starting off with colder weather than anything we saw in 2018. In fact, 2018 was the 6th warmest year on record for Fairbanks.
A low temp of 33F was recorded several times during the winter of 2017-18. That low temp of 33 in January & February was a tie for the second warmest low temp on record.
The high temp for all of 2018 was 88F on 22 July.
2018 was also wet, which comes as no surprise. It was the fifth year in a row that Fairbanks saw substantially above average precipitation. Last winter, Fairbanks had 70.6″ of snowfall, which is only slightly higher than average. We really added to that with some wetter than normal summer months.
Three out of the past five years (2014, 2016, 2018) make the top ten warmest on record.
