Several regions in the US state of Alaska are grappling with unusually high temperatures, triggering the first-ever heat advisories in the state's recorded history. This follows a recent shift in the National Weather Service (NWS) alert system, which traditionally relied on special weather statements to communicate high temperature risks.
From June 1st, the NWS authorised the use of heat advisories in Alaska, bringing the state in line with Hawaii and the other 48 contiguous US states. Experts suggest this change aims to improve public awareness and communication regarding the potential impacts of extreme heat.
Currently, parts of central and eastern interior Alaska, including areas near Tanana, Fairbanks, Fort Yukon, and Eagle, are under heat advisory from Sunday, June 15th to Tuesday, June 17th. Temperatures are expected to reach between 29 and 32 degrees Celsius, which, while not extreme globally, is significantly warmer than usual for the region.
"It'll definitely be warm, especially for Alaska's standards," commented meteorologist Adam Douty.
Beyond the heat, melting ice and snow in the northern regions pose a flood risk, with corresponding flood advisories in effect.
Furthermore, certain areas are under a red flag warning until 23:00 local time on Monday, June 16th. This warning indicates a high risk of large and dangerous wildfires due to the hot and dry conditions. These areas include the Dalton Highway Summits, Yukon Flats, White Mountains, and the high terrain south of the Yukon River.
This unusual heatwave is raising concerns about the potential impact on local ecosystems and infrastructure in a region typically accustomed to much cooler temperatures.
