In meteorology, a williwaw (archaic spelling williwau [1] ) is a sudden blast of wind descending from a mountainous coast to the sea. The word is of unknown origin, but was earliest used by British seamen in the 19th century. The usage appears for winds found in the Strait of Magellan, the Aleutian Islands and the coastal fjords of the Alaskan Panhandle, where the terms outflow wind and squamish wind are also used for the same phenomenon. On Greenland the word piteraq is used.
The williwaw results from the descent of cold, dense air from coastal mountains in high latitudes. Thus the williwaw is considered a type of katabatic wind. [2]
Sand Point, also known as Popof Island, is a city in Aleutians East Borough, Alaska, United States. At the 2010 census the population was 976, up from 952 in 2000, but by the 2020 Census this had reduced to 578. It is on northwestern Popof Island, one of the Shumagin Islands, off the Alaska Peninsula. It is the borough seat of Aleutians East Borough, and is near the entrance to the Bering Sea.
A katabatic wind carries high-density air from a higher elevation down a slope under the force of gravity. Such winds are sometimes also called fall winds; the spelling catabatic winds is also used. Katabatic winds can rush down elevated slopes at hurricane speeds, but most are not that intense and many are 10 knots or less.
Chinook winds, or simply Chinooks, are two types of prevailing warm, generally westerly winds in western North America: Coastal Chinooks and interior Chinooks. The coastal Chinooks are persistent seasonal, wet, southwesterly winds blowing in from the ocean. The interior Chinooks are occasional warm, dry föhn winds blowing down the eastern sides of interior mountain ranges. The coastal Chinooks were the original term, used along the northwest coast, and the term in the interior of North America is later and derives from the coastal term.
USS Admirable (AM-136) was the lead ship of her class of minesweeper built for the United States Navy during World War II. In commission from 1943 to 1945, she was transferred to the Soviet Navy in 1945 and served as T-331 until stricken in 1958.
Adak Island or Father Island is an island near the western extent of the Andreanof Islands group of the Aleutian Islands in Alaska. Alaska's southernmost city, Adak, is located on the island. The island has a land area of 274.59 square miles (711.18 km2), measuring 33.9 miles (54.5 km) long and 22 miles (35 km) wide, making it the 25th largest island in the United States.
The Aleutian Islands campaign was a military campaign fought between 3 June 1942 and 15 August 1943 on and around the Aleutian Islands in the American Theater of World War II during the Pacific War. It was the only military campaign of World War II fought on North American soil.
A squamish is a strong and often violent wind occurring in many of the fjords, inlets and valleys of British Columbia. Squamishes occur in those fjords oriented in a northeast–southwest or east–west direction where cold polar air can be funneled westward, the opposite of how the wind generally flows on the Coast. These winds in winter can create high windchills by coastal standards of −20 to −30 °C. They are notable in Jervis, Toba, and Bute Inlets and in Dean Channel and the Portland Canal. Squamishes lose their strength when free of the confining fjords and are not noticeable more than 25 km offshore.
Buldir Island is a small island in the western Aleutian Islands of the U.S. state of Alaska. It is 4.3 miles (6.9 km) long and 2.5 miles (4.0 km) wide with an area of 7.4482 square miles (19.291 km2). Buldir is farther from the nearest land than any other Aleutian Island. Its nearest neighbors are Kiska in the Rat Island group, 68 miles (109 km) to the east, and Shemya in the Near Island group, 64 miles (103 km) to the west. Buldir Island is uninhabited. It is part of the Alaska Maritime National Wildlife Refuge. It has been designated a Research Natural Area.

Ilak Island is a small island in the eastern Delarof Islands, Aleutian Islands of Alaska.
Montague Island (Sugpiaq: Suklluurniilnguq) lies in the Gulf of Alaska at the entrance to Prince William Sound, Alaska. The island has a land area of 790.88 km2, making it the 26th largest island in the United States. As of the 2000 census, Montague did not have a permanent resident population, making it at that time the largest uninhabited island in the United States. Since then, the 2010 abandonment of the United States Coast Guard station on Attu Island in the Aleutian Islands, which at 892.8 km2 is larger than Montague Island, causes Attu to claim that title. Montague Island was named by Captain James Cook in honor of John Montagu, 4th Earl of Sandwich, one of his greatest supporters.
The Battle of Dutch Harbor took place on 3-4 June 1942, when the Imperial Japanese Navy launched two aircraft carrier raids on the Dutch Harbor Naval Operating Base and U.S. Army Fort Mears at Dutch Harbor on Amaknak Island, opening the Aleutian Islands campaign of World War II. The bombing marked the first aerial attack by an enemy on the continental United States and was the second time in history that the continental U.S. was bombed by someone working for a foreign power, the first being the accidental bombing of Naco, Arizona, in 1929.
The third USS Casco (AVP-12) was a United States Navy Barnegat-class small seaplane tender in commission from 1941 to 1947. She saw service in World War II. After her decommissioning, the U.S. Navy loaned her to the United States Coast Guard, in which she served as the cutter USCGC Casco (WAVP-370), later WHEC-370, from 1949 to 1969.
The Battle of Attu, which took place on 11–30 May 1943, was fought between forces of the United States, aided by Canadian reconnaissance and fighter-bomber support, and Japan on Attu Island off the coast of the Territory of Alaska as part of the Aleutian Islands campaign during the American Theater and the Pacific Theater. Attu is the only land battle in which Japanese and American forces fought in snowy conditions, in contrast with the tropical climate in the rest of the Pacific. The battle ended when most of the Japanese defenders were killed in brutal hand-to-hand combat after a final banzai charge broke through American lines.
The Japanese occupation of Kiska took place between 6 June 1942 and 28 July 1943 during the Aleutian Islands campaign of the American Theater and the Pacific Theater of World War II. The Japanese occupied Kiska and nearby Attu Island in order to protect the northern flank of the Japanese Empire.
The Aleutian Islands —also called the Aleut Islands, Aleutic Islands, or, before 1867, the Catherine Archipelago—are a chain of 14 main, larger volcanic islands and 55 smaller ones. Most of the Aleutian Islands belong to the U.S. state of Alaska, with the archipelago encompassing the Aleutians West Census Area and the Aleutians East Borough. The Commander Islands, located further to the west, belong to the Russian federal subject of Kamchatka Krai, of the Russian Far East. The islands form part of the Aleutian Arc of the Northern Pacific Ocean, and occupy a land area of 6,821 sq mi (17,666 km2) that extends westward roughly 1,200 mi (1,900 km) from the Alaskan Peninsula mainland, in the direction of the Kamchatka Peninsula; the archipelago acts as a border between the Bering Sea to the north and the Pacific Ocean to the south. Crossing longitude 180°, at which point east and west longitude end, the archipelago contains both the westernmost and easternmost parts of the United States, by longitude. The westernmost U.S. island, in real terms, however, is Attu Island, east of which runs the International Date Line.
The November 2011 Bering Sea cyclone was one of the most powerful extratropical cyclones to affect Alaska on record. On November 8, the National Weather Service (NWS) began issuing severe weather warnings, saying that this was a near-record storm in the Bering Sea. It rapidly deepened from 973 mb (28.7 inHg) to 948 mb (28.0 inHg) in just 24 hours before bottoming out at 943 mbar, roughly comparable to a Category 3 or 4 hurricane. The storm had been deemed life-threatening by many people. The storm had a forward speed of at least 60 mph (97 km/h) before it had reached Alaska. The storm began affecting Alaska in the late hours of November 8, 2011. The highest gust recorded was 93 mph (150 km/h) on Little Diomede Island. One person was reported missing after being swept into the Bering Sea, and he was later pronounced dead.
Williwaw is the debut novel of Gore Vidal, written when he was 19 and first mate of a U.S. Army supply ship stationed in the Aleutian Islands. The story combines war drama, maritime adventure and a murder plot. The book was first published in 1946 in the United States by E.P. Dutton. Williwaw is the term, widely thought to be Native American in origin, for a sudden, violent Katabatic wind common to the Aleutian Islands.
The landing at Amchitka on 12 January 1943 was the unopposed amphibious landing operation and occupation of Amchitka island by American forces during the Aleutian Islands campaign during World War II.
FV Scandies Rose was a crab fishing vessel built in 1978 by Bender Shipbuilding out of Mobile, Alabama. Originally named Enterprise, she was registered in Dutch Harbor, Alaska. She mainly fished for king crabs, opilio crabs, and Pacific cod, in both the Bering Sea and the Gulf of Alaska. The sinking of the vessel became more widely known due to its relation to the reality TV-show Deadliest Catch.
