 21 September 1588 → After an unsuccessful battle with the English fleet, the Spanish Armada encountered strong storms and high winds off the coast of Ireland on its way back to Spain. 26 ships are believed to have been lost. The remaining ships limped back to Spain defeated and demoralized, ending the reign of the once unbeatable Spanish Armada.
 21 September 1894 → A huge tornado outbreak swept from Iowa through Minnesota to Wisconsin, with an unusual number of extremely violent tornadoes. The tornado that rampaged through Kossuth County, MN, was likely an F5 as homes and farms were wiped clean from the earth.
 21 September 1909 → A category 3 hurricane crossed the Gulf of Mexico and came ashore in southern Louisiana. The storm inflicted 120 mph winds on southeast Louisiana and took its storm surge 2 miles inland. There were about 371 fatalities despite the Weather Bureau having issued its first warnings for the storm three days earlier.
 21 September 1938 → The New England Hurricane was one of the most destructive and powerful storms ever to strike southern New England. The storm roared ashore over Long Island, NY at nearly 60 mph at the time of high tide. This created a deadly tidal surge, which submerged downtown Providence, RI under 20 feet of water. Hurricane force winds were felt throughout New England, with a gust to 186 mph at the Blue Hill Observatory in Milton, MA. The Great New England Hurricane of 1938 was responsible for over 500 deaths.

November 9, 1977:

An intense early winter storm center moved northeast from Colorado to north central Iowa during the morning of November 9th, and then to Lake Superior by the morning of November 10th. In most areas, the precipitation began late on the 8th as rain with temperatures in the 50s, changing to snow early on the Wednesday the 9th, with the storm continuing through Thursday the 10th. In west central Minnesota, some freezing rain also occurred before it changed to all snow. As the storm intensified, the winds in the eastern half of South Dakota increased with some gusts as high as 60-70 miles per hour with widespread visibilities reduced to zero in blowing snow. In west central Minnesota, north to northwest winds of 60 to 80 mph reduced visibility to zero and piled snow into eight-foot drifts. The temperature dropped rapidly into the 20s. Many roads throughout the eastern part of South Dakota and west central Minnesota were blocked, and snow plows were immobilized by the heavy wet snow. Many cars and trucks were snowbound on the roads and highways. Approximately 100 cars and trucks were stalled on Interstate 90, east of Murdo. Near Fergus Falls in western Minnesota, two trucks loaded with turkeys became stuck and half the birds were frozen. Many schools were closed on the 9th and 10th. Snowfall amounts in the eastern half of the state were generally greater than four inches. A band of very heavy snow, ten inches or more, extended from Bridgewater to Howard to Clear Lake into parts of west central Minnesota. A 1400-foot TV tower at Garden City was also destroyed by the high winds. There was some loss to the corn crop. Sunflowers comprised the greatest loss, because they had not been completely harvested. Reports of livestock losses were minimal. Some storm total snowfall amounts include; 15 inches in Watertown; 14 inches in Sisseton; 12 inches in Clear Lake and Wheaton; 10.5 inches in Castlewood; and 9 inches near Raymond and Bryant.

November 9, 1982:

The occurrence of tornadoes in Southern California is not a common event. However, on this day, a total of 7 tornadoes touched down in the Los Angeles area during a winter type storm. The strongest tornado reached F2 strength. Two of the tornadoes began as waterspouts which moved onshore at Point Mugu and Malibu. The tornadoes generally moved from a SSW to the NNE in advance of an approaching cold front. The Long Beach tornado was the longest and most damaging of the tornadoes. Starting near the Queen Mary ocean liner, it travelled 10 miles northward along the Los Angeles River.
