"La route ? Là où on va, on a pas besoin de route."
3 portions de routes complètement enneigées entre Siglufjörður et Akureyri. Les paysages sont quasiment invisibles.
Blanc, si blanc, tellement blanc ! Je devrais trouver ça triste. Au contraire, conduire sous ce temps est excitant (et un poil flippant avec les plaques de glace surprise).
Alaska heat: Fairbanks Airport Tuesday 1230pm AKST up to 44F (6.7C). This is a new record high temperature for Feb 20, previous record of 41F (5.0C) set in 2008. It’s also the highest February temperature in 20 years. Climate observations in the Fairbanks area since late 1904. #akwx#Winter2024@Climatologist49@CarrieinFbx@anisian@debmcqueen@dboo@mivox
Photo prise par mon colocataire russe cette nuit vers 1h du matin dans le secteur de Krysuvik (route 42), soit à une vingtaine de kilomètres du site de l'éruption.
J'ai refais une petite randonnée du côté de la station géothermale de Seltún parce que j'avais envie de faire mon Jésus en marchant sur l'Arnarvatn gelé (environ 20 à 30 cm de glace).
Température : environ -20°C. J'ai jamais eu froid (sauf aux mains quand il fallait prendre des photos et des vidéos).
Vent : 10m/sec. résister face aux bourrasques était parfois compliqué mais ça m'a permis de faire de belles images !
Noël avec les colocataires russes ! Repas à l'islandaise avec agneau fumé, pommes de terre et légumes crus. Tiramisu maison au dessert. On a parlé religion et politique russe en toute quiétude.
Côté cadeaux :
Colocataires : du café Kenyan et un livre sur les mœurs islandais durant Noël.
La bonne nouvelle : j'avais complètement oublié que le 26 décembre est un jour férié en Islande (Annar í jólum), une sorte de Boxing Day à l'américaine. Bon ben, allons randonner près des volcans !
La mauvaise nouvelle : ...
En rentrant, j'ai trouvé le journal annuel des secouristes. Celui-ci donne les dates d'ouvertures de ses points de vente pour acheter les feux d'artifices (28/12 - 31/12). Dans ce pays, seuls les services de secours peuvent vendre ce type de produit.
Nerd alert: Fairbanks and Interior Alaska appear be setting up for the longest sustained cold during an El Niño winter since 1972-73. ECMWF ensembles for 850mb temperatures keep it very cold into early February. How cold it gets mostly depends on clouds. No clouds, very cold. Some clouds, less cold.

Bettles, Alaska (northern Interior, Koyukon Dene county) Sunday high temperature will very likely be -50F (-45.6C). This would be a new record for the lowest high temperature on Jan 28, breaking the previous record of -47F (-43.9C) set in 2012. This would also be the latest date in the winter with a high temperature of -50F. Previous latest was Jan 27, 1989.

Always amazing how precipitation (rain plus the water in melted snow) can vary in complex terrain, not just storm to storm but even across several months. November 2023 through January 2024
Anchorage Airport: 220 percent of normal precipitation and the highest NDJ total of record.
Meanwhile, 35 miles away at
Girdwood: precipitation was a little bit below normal (94%) #akwx#Climate#Winter2024@Climatologist49@EyeOnAlaska
Alaska’s Cold Snap 2024 is done. In some areas the past two weeks featured the coldest sustained weather in 15 years. At others, a day or two of intense cold was more prominent. While quite cold for the 21st century, this event doesn’t even rate an asterisk compared to 20th century cold snaps. Lowest community temperature was at perennially cold spot of Chicken at -62F (-52.2C). #akwx#Arctic#Cold#Winter2024#Alaska @Climatologist49
January 2024 was significantly warmer than the 1991-2020 normal across the eastern Canadian Arctic, northern and western Alaska and far northeast Russia, and far western Siberia. Parts of eastern Siberia, northwest Canada and the Nordic Arctic were colder than normal. Overall, January ranked as the 14th warmest for the #Arctic (north of 60ºN) since 1950.

Fairbanks, Alaska high temperature today of -9F (-22.8C) is the second lowest leap day high temperature in the past 116 years. Only February 29, 1956, with a high of -16F (-26.7C), was colder. #akwx#Winter2024 @CarrieinFbx@debmcqueen@leepetersen
Winter 2023-24 climate summary for the Arctic is now out on the Alaska and Arctic Climate Newsletter. Yep, warm (relatively speaking). #Arctic#Climate#Winter2024
Anchorage Airport is at 123.6 inches of snow for the season. The record is 134.5 inches. Ten years since 1953 have had enough snow to set a new record. So knowing nothing else, it’s unlikely but by no means out of the question that this finishes as Anchorage’s snowiest winter of record. #akwx#snow#Climate#Winter2024#Alaska@Climatologist49@EBecker@patrace@EyeOnAlaska@sbmorgan
