Notes and comments, and occasionally, news about visiting Alaska.

Be Careful What You Wish For

I was headed out of my office yesterday for lunch, and ran into the woman who has the office next to mine. She was just coming inside the building from the pouring rain. I looked at her and said, “We should be a little more careful when we start wishing it would warm up…”

I then dashed out into the rain-and-50-degree weather. For the uninitiated, rain and 50 degrees is actually a fairly common combination in Alaska in the summer and early fall. In January, it is, thankfully, rare.

Alaska had been suffering from some rather intense cold weather, stretching back to around Christmas. Clear skies and falling temperatures were the rule, with many places in the interior of Alaska dropping into the -50F range. Here in Anchorage, temperatures ranged from -20F to -30F. In theory, Alaskans are prepared for such weather, and to our credit, we seemed to get along just fine. But one could not wander down the street or into a restaurant, or answer a phone without launching into a conversation about the relentless cold.

Alaskans can do cold, but we don’t like it too much. Even I was complaining – and I am usually pretty stoic about the weather.

Last weekend, I decided to make a trip to Fairbanks to visit a friend and take care of some business. I was greeted by -40F temperatures and ice fog*. I knew I would find these extremes there, so I packed all of my hard-core winter gear, and in fact, I was very comfortable wandering around in the cold. We even made a trip to Chena Hot Springs and took a dip in the outdoor rock pool.

The problem with the cold weather is that while most Alaskans have all the cold weather gear, it is rather tedious putting all the layers on just to make a trip to the store to get some milk. Heading out the door takes an additional five minutes of preparation as we stack scarves and hats and fleece and parkas over our sweaters, only to have to reverse the process when we get to where we’re going. So some of us skip a layer here or there, and shiver as we drive to the grocery store – and complain bitterly once we get there… “I wish it would warm up!”

So we got what we wished for. To be clear, our warmup was actually more extreme than our cold. On January 16, Anchorage set a high temperature record for the date, reaching 50 degrees (the old record was 44), and this was the second warmest official temperature ever recorded in Anchorage in January. Merrill Field, the large general aviation airport located on the north side of town reached 52. Up in the Fairbanks area, Eielson Air Force base reached 52F, and this is a 100 degree swing from the temperatures recorded there just last week!

You would think that we would be thankful for the warm weather… But in fact, the warmup has caused us all sorts of problems.

A winter of cold has chilled the ground quite well, and despite the balmy breezes, the ground is quite frozen. So rain and melting snow run into the roads, where they are immediately frozen to a sheen that any Zamboni driver would be proud of. All through our cold snap, Anchorage schools operated without a hitch. Warm things up to 50 degrees, and schools close for three days due to persistently icy roads.

To make it all worse, the warm weather is accompanied by strong winds. In fact, the warm weather wouldn’t be possible without the strong winds – the winds are warmed by their interaction with the mountains, creating what is commonly called a chinook. We get our share of chinooks every winter, but this one was accompanied by 100+ MPH winds, which downed trees and power lines. And to make the whole experience complete, the persistent warm weather and rain has melted snow. Storm drains are clogged with ice, so the water has no place to go, and forms small lakes on the roadways. The water that has managed to run off doesn’t sink into the soil, but runs along the ground and into ice-choked streams that have flooded several low-lying areas and roads.

My driveway is a sheet of ice. I am headed out today to get a couple large bags of salt (if there is any to be had), so I can try to break the ice up before it gets too cold to get rid of it.

The good news is, we’ll have just one more story about the weather to tell.

*ice fog forms when the atmosphere reaches a temperature where it has no capacity to hold water vapor. This is when temperatures are below -40. Moisture that enters the air from auto exhaust or from the burning of fuels are transformed into microscopic ice crystals that form a very dense fog.

  • I’m just guessing, but I think I would not want to breathe ice fog, at least through my mouth.

    Here’s wishing you more moderate winter weather soon. (Ours in Maryland is fine; it’s plenty cold, but there’s little wind and no frozen precipitation.)
