A heat advisory has been issued for southern Alaska, marking the earliest warning of its kind from the National Weather Service (NWS) in Juneau. The advisory is set to last from 10 a.m. to 8 p.m. AKDT, with temperatures expected to rise to 80-85°F, significantly higher than the usual 60°F average for this time of year. This unusual early-season heat poses risks for residents who are not acclimatized to such conditions, particularly vulnerable populations like the elderly. The advisory covers areas including Prince of Wales Island and the Ketchikan Gateway Borough. NWS meteorologist Daniel Slagle noted that this year's heat advisory comes earlier than last year's first advisory on June 18. With a high-pressure ridge bringing sunshine, the potential for heat-related illnesses increases as homes in Alaska often lack air conditioning. Residents are advised to take precautions, such as staying hydrated and checking on those at risk. While the advisory is a one-day event, it underscores the rapid shifts in climate conditions in Alaska, where extreme temperatures can strain local infrastructure.
