 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.

April 5, 2000:

High winds of 35 to 50 mph gusting to around 70 mph blew across central and north central South Dakota from the late morning to the late afternoon hours. As a result, several trees and many tree branches were downed, many structures, roofs, billboards, and road signs were damaged, a few mobile homes were overturned, and some power outages occurred. Not only did the high winds make driving difficult but, at some locations, they stirred up dirt causing visibilities to drop to near zero at times. Some detours and traffic collisions resulted due to the low visibility in blowing dirt. Airborne objects broke some windows across the area. One house had all of the windows on the front porch blown out. Also, a few semi tractor-trailers were tipped over by the high winds. Wind gusts included, 60 mph at Pierre, 63 mph at Kennebec, 64 mph at Mobridge, 65 mph at Pollock, and 71 mph at McLaughlin. The high winds and extremely dry conditions combined with downed and arcing electrical lines, out of control burns, and smoldering embers from previous fires resulted in several grassfires across central and north central South Dakota. Several thousand acres of grassland, hundreds of haybales and haystacks, along with some trees and fences were burned. Also, the smoke from some of these fires created low visibilities and difficult driving conditions on some roads.
