“Despite the fact that the Aleutian Archipelago is remote and largely uninhabited, it nonetheless has a long history of predator exploitation, and is also at the front lines of climate change,” said Douglas Rasher. An eruption of Cleveland Volcano in the Aleutians as seen from the International Space Station. In recent times the highest recorded temperature in December has been 12°C that's 54°F, with the lowest recorded temperature -17°C, about 1°F. Easterly winds are relatively uncommon. The Aleutian Low is one of the principal causal factors of the weather and climate in the Unimak region. The Aleutian Low storm tracks are shown in the map to the right. Pilot Point, Aleutian Islands, Alaska weather conditions, average/minimum/maximum temperature, humidity variation graphs. 23 November 2020 at 20:00-21:00: Rain, Temperature 7, 0.5 mm, Gale, 18 m/s from south Summer temperatures are also moderated by the strong marine environment so that daytime highs seldom surpass 70 degrees F.  Temperature extremes increase as one travels up the Alaska Peninsula, so that Cold Bay is slightly colder in winter and warmer in summer than Unimak Island. King Cove City, Aleutian Islands current conditions, weather forecast and climate chart (temperature and humidity). This means that the winds will change direction and intensity as a low pressure storm passes by. The Aleutian Islands experience oceanic climate with heavy rainfall and moderate temperatures. Their website on "The Cryosphere Today" can be accessed here and it contains the most up-to-date information on ice in the Bering Sea, the Beaufort Sea and other world sea ice areas. A deep-draft vessel that intends to come within 3 nautical miles of the Aleutian or Pribilof Islands and anchor to avoid severe weather shall notify the Coast Guard as soon as practicable in accordance with 33 CFR 160.215: CONTACT INFORMATION: Their color variations are probably due to differences in temperature and in the size of water droplets that make up the clouds. This is also the zone where the colder air from the subarctic meets the warmer moist air to the south. “In the early years, it was a very different place,” Estes said. Temperatures range from average lows of -7O°C to -20°C in winter to average highs of 10°C to 13°C in summer (Gallant et al. Pilot Point, Aleutian Islands, Alaska free weather widget (free script for your website or blog). The chart below plots the average number of days in any month that you can expect to see snow falling. An old Aleut saying is:  "The wind is not a river." King Cove City, Aleutian Islands free weather widget (free script for your website or blog). The temperature regime for the Unimak area is documented at the Cold Bay weather station, about 30 miles northeast of False Pass on the Alaska Peninsula. For Aleutian Islands in the coming week the average daytime maximum temperature will be around 7°C, with a high for the week of 15°C expected on the afternoon of Thursday 29th. A powerful storm swirled through the Aleutian Islands of Alaska this week, providing incredible satellite images and producing wind gusts near hurricane force. Compared to neighboring regions, the Alaska Peninsula / Aleutian Islands region is categorized by a cooler, drier climate. Bad weather reigns, the wind and rain conspiring to create the perfect conditions for hypothermia. The Aleutian Island area has the highest average wind speed of any area in the U.S.  Average wind speeds are 15.6 MPH for Cold Bay, with the highest averages from September through May. American Geophysical Union annual … Agriculture thrives between early May and late September. 1995). Comfort Levels: Given average maximum temperatures and humidity levels generally you should not anticipate any discomfort from heat (see heat index for more information). If the storm center passes to the south of Unimak, there is a backing windshift, starting with southeast, then backing to east, northeast and finally northwest as the storm center moves away. Temperature. Precipitation varies widely, from 530mm up to 2,080mm. Then, if the storm passes by to the north of Unimak, the winds veer towards the southwest and then west, and as the storm leaves the area, winds blow from the northwest and then start diminishing. The graph shows that the area of ice in the Bering Sea often fluctuates substantially from the 1979-2008 mean, usually in the range of about +-10 to 25%. The two primary wind directions the year around for the Unimak area are southeast and its opposite, northwest. Even though global warming would suggest a reduced ice pack in 2012, the ice area is an anomalous record high for the period that began in 1979. The chart below plots the average daily wind speed you can expect for any month. characteristics of climate variability that may pertain to the climate hypothesis regarding the long-term population decline of Steller sea lions (Eumetopias jubatus). Fogs are almost constant. The Aleutian Low's location and intensity is shown in the above three maps in relation to the stationary North Pacific High that lies to the south. "This was the driest July in 95 years in the Aleutian region there, which includes basically from False Pass westward, as well as the Pribilof Islands," said Thoman. A total of 110 culverts are known, of which 49% have or likely to have fish passage problems. King Cove City, Aleutian Islands weather conditions, average/minimum/maximum temperature, humidity variation graphs. Westerlies often occur in the fall, as shown in the wind direction rose for September. By Tuesday morning, low-pressure storms originating from over Siberia (Russia) quickly push east and combine with some of the storms over the Aleutian Islands. Precipitation falls in every month of the year but is heaviest August through December, as seen in the graph on the right. The days with the heaviest rainfall occurs in the fall, but strong storms can bring southeast winds and heavy rainfall at other times of the year. The forecasts Expect 0.7 mm of precipitation over the past 3 hours. The Heat Index is a measure of how hot it feels when relative humidity is added to actual air temperature. The Aleutian Island is mostly cone volcano’s and some are still activate, but only on one side of the Island not all of the volcano’s can still activate. An intense low-pressure storm system packing strong winds and massive waves is expected to move over the Bering Sea and through the Aleutian Islands of Alaska this weekend, weather … The wettest time of the year is September through December. The storm track almost always leads from the west toward the east along the Aleutian chain. Although extensive data doesn't seem to be available on the southern extent of Bering Sea ice, the available data and anecdotal evidence indicates that the sea ice edge seldom goes beyond Isanotski Strait and rarely as far as Unimak Pass. A low pressure system lifting through the Great Lakes today will produce some heavy snow. The summers are relatively quieter, but even then gale force winds usually occur. Shemya or Simiya (Aleut: Samiyax̂) is a small island in the Semichi Islands group of the Near Islands chain in the Aleutian Islands archipelago southwest of Alaska, at CoordinatesIt has a land area of 5.903 sq mi (15.29 km 2), and is about 1,200 miles (1,900 km) southwest of Anchorage, Alaska.It is 2.73 miles (4.39 km) wide and 4.32 miles (6.95 km) long. In 1970, Jim Estes made his first trek up to Alaska’s Aleutian Islands.He was greeted by an ocean filled with furry faces. Wind gusts over 50 MPH occur 3 or more days per month for 7 months of the year. The Unimak Area of Alaska shows very small seasonal changes in temperature, as seen in the map to the right. These cloud formations were seen over the western Aleutian Islands. Make it a Weather Favorite! This creates a large band of atmospheric instability with rising moist air that stretches from the Kamchatka Peninsula in the west and all the Aleutian Islands chain. Since this area is in the zone of the westerly winds, moist air and relatively warm temperatures come into the area after having traveled over extensive ocean areas. Below is a picture of ice filling Isanotski Strait in False Pass.4, Amak Island lies just off shore from Isanotski Strait in the Bering Sea and it was historically a walrus hauled out, indicating that the edge of the Bering Sea ice pack was near by. The objective of this paper is to highlight those characteristics of climate variability that may pertain to the climate hypothesis regarding the long‐term population decline of Steller sea lions (Eumetopias jubatus).The seasonal changes in surface air temperature (SAT) across the Aleutian Islands are relatively uniform, from 5 to 10°C in summer to near freezing temperatures in winter. The chart below plots the average number of days in any month that you can expect to see rain falling. Calm winds (no direction) in Cold Bay are observed only 2% of the time. The map shows that the weaker Aleutian Lows (AL) often move into the western Bering Sea. The Maximum wind gust during this period was 83 MPH, but every month had gusts of 60 MPH or over. The region experienced record-breaking heat and record-dry conditions. Precipitation in the Unimak area occurs in all months of the year, there is no dry season. The Aleutian Low is one of the principal causal factors of the weather and climate in the Unimak region. The wind direction is very important to local fishermen and mariners. Multi-disciplinary evidence for a large, previously unrecognized caldera in the Islands of Four Mountains, Central Aleutian Arc, Alaska. Throughout the month of December daytime temperatures will generally reach highs of around 2°C that's about 36°F. The chart below plots the average high and low temperature for each month of the year. Summer weather is much cooler than Southeast Alaska (around Sitka), but the winter temperature of the islands and of the Alaska Panhandle is very nearly the same. Given the small landmass, the human footprint is quite large — the region is ranked 5th out of the 13 regions for human impacts. Throughout the month of December daytime temperatures will generally reach highs of around 2°C that's about 36°F. Wind conditions in the Unimak area are the most important weather factor for local fishermen. At night the average minimum temperature drops down to around -2°C, that's 29°F. This work is being done at the University of Illinois/Urbana-Champaign at the Polar Research Group/ Dept. The 7 day weather forecast summary for Aleutian Islands: For Aleutian Islands in the … The stronger ALs generally move eastward south of the Aleutian Islands. The average daily relative humidity for December is around 84%. Since travel and work at sea depends upon favorable wind conditions, wind direction will determine where a fisherman can fish or where he can travel by sea. When he first visited Amchitka Island, he could count anywhere from 50 to 300 sea otters from the shore. A combination of climate warming and loss of sea otters is harming the reefs that underpin Alaskan kelp forests in the Aleutian Islands. Eddy energy in the Aleutian Islands region has been low from the fall 2012 through 2018, indicating the likelihood of smaller than average fluxes of volume, heat, salt, and nutrient fluxes through Amukta Pass (p. 49). The Aleutian Low shifts position and changes in intensity with the seasons. Winds and tides can bring drift ice from the edge of the Bering Sea ice pack into Isanotski Strait and as far south as Ikatan Bay. During the winter, it is located farther south, and is large, semi-permanent, and most intense. There is little concern about whether the day will be sunny or cloudy or even rainy, it is the wind that matters most because it determines the safety of traveling by boat or skiff. The chart below plots the average monthly precipitation amount. The Islands of the Four Mountains in Alaska’s central Aleutians are about as inhospitable an environment as a person can imagine. The climate profile is taken from closest available data source to Aleutian Islands. As a storm approaches our area from the west, the wind sets in from the southeast and builds in intensity. Lows in the mid 30s. The average annual temperature for the inhabited islands is about 38 °F in January and 52 °F in August. Storms over the Central Aleutian Islands will bring warm air up from the south as well as rain to the islands Monday into Tuesday. It also shows the maximum recorded sustained wind speed for each month. The "Cradle of the Storms" is the colloquial name for the Aleutian Low area because this is the stormiest area in the north Pacific.2  These cyclonic storms generally travel eastward along the Aleutians in the zone of the westerly winds. Animated monthly wind direction graphs can be seen here. An active weather pattern will impact the U.S. this weekend into next week. Ice in the southern Bering Sea that extends as far as Isanotski Strait has a general chilling effect on temperatures in winter since the moderating effect of open water is gone. During such cold winters, the Bering Sea can be covered with ice as far as Isanotski Strait and cold Siberian air can drive the temperatures down to near zero. This means that the Unimak Area is generally free from winter incursions of cold air from the Alaska mainland and only occasionally does cold Siberian area make its way across the Bering Sea to the Aleutian Islands, although in particularly cold winters this does happen. The strongest of these storms may make their way to the west coast of North American during the winter and then move across the mid section of the U.S..
