![]() Above average temperatures of 1 to 4 degrees Celsius (2 to 7 degrees Fahrenheit) were found just off the coast in the Laptev Sea, the southern Beaufort Sea off the coast of Canada, and in the East Greenland Sea and stretching towards Svalbard. Yellows and reds indicate high air pressure blues and purples indicate low pressure.Ĭredit: NSIDC courtesy NOAA Earth System Research Laboratory Physical Sciences LaboratoryĪir temperatures at the 925 millibar level (approximately 2,500 feet above the surface) over the Arctic Ocean were mixed (Figure 2a). This plot shows average sea level pressure in the Arctic in millibars for June 2023. At the end of June, total sea ice extent was below that in 2022, but higher than in 20. In the Sea of Okhotsk and the Bering and Barents Seas, where ice retreat generally starts before June, the ice loss has been slower than average. ![]() This includes the Beaufort, Chukchi, Laptev, Kara and East Greenland Seas. In regions which normally lose sea ice this time of year, the rate of ice loss was faster than average. This summer, 2.30 million square kilometers of ice melted (880,000 square miles). On average, based on the 1981 to 2010 mean, about 1.69 million square kilometers (653,000 square miles) of ice is lost in June, roughly the size of Alaska. Through much of June 2023, extent declined faster than the 1981 to 2010 average (Figure 1b). The average extent was 800,000 square kilometers (309,000 square miles) below the 1981 to 2010 average and 550,000 square kilometers (212,000 square miles) above the record low June extent, which occurred in 2016.

The graph above shows Arctic sea ice extent as of July 5, 2023, along with daily ice extent data for four previous years and the record low year. Travelers in Aspen should call their airlines and check for updates.Figure 1b. Most airlines are canceling flights in and out of Denver International Airport this weekend and waiving change fees. The Aspen High girls swim team will wait until next week to travel to the Class 3A girls swimming state championship, which was moved to Monday in the northern Denver suburb of Thornton. “I encourage you to be in a relatively safe location from shortly after sunrise Saturday through Sunday afternoon if it’s snowing in your area,” the governor said Thursday.Ī number of Front Range events are being canceled or postponed this weekend. Jared Polis said he is making available about 50 members of the Colorado National Guard to help with search and rescues as needed. ![]() In a news conference Thursday afternoon, Gov. ![]() The NWS Boulder office said Thursday that 15 to 25 inches of snow is expected across the Denver area with “up to 30 inches in Boulder and Fort Collins (and) 2 to 4 feet of snow in the foothills.“ ![]()
