SEPTEMBER 24TH, 1926 |
The temperature at Yellowstone Park dipped to nine degrees below zero. It was the coldest reading of record in the U.S. during September. |
SEPTEMBER 24TH, 1950 |
A smoke pall from western Canada forest fires covered much of the eastern U.S. Daylight was reduced to nighttime darkness in parts of the Northeast. The color of the sun varied from pink to purple, blue, or lavendar. Yellow to grey-tan was common. |
SEPTEMBER 23RD, 1983 |
A thunderstorm downburst caused a timber blowdown in the Kaibab National Forest north of the Grand Canyon. Two hundred acres were completely destroyed, and scattered destruction occurred across another 3300 acres. Many trees were snapped off 15 to 30 feet above ground level. |
SEPTEMBER 23RD, 1815 |
One of the greatest hurricanes to strike New England made landfall at Long Island and crossed Massachusetts and New Hampshire. It was the worst tempest in nearly two hundred years, equal to the hurricane which struck in 1938, and one of a series of severe summer and autumn storms to affect shipping lanes that year. |
SEPTEMBER 22ND, 1961 |
Hurricane Esther made a near complete circle south of Cape Cod. The hurricane then passed over Cape Cod and hit Maine. Its energy was largely spent over the North Atlantic Ocean, however, heavy rains over Maine resulted in widespread local flooding of cellars, low roads, and underpasses. |
SEPTEMBER 22ND, 1987 |
Hurricane Emily, the first hurricane to roam the Carribean in nearly six years, made landfall over the Dominican Republic late in the day, packing 125 mph winds. Emily killed three persons and caused thirty million dollars damage. |
SEPTEMBER 21ST, 1894 |
A heavy chicken house, sixteen by sixteen feet in area, was picked up by a tornado and wedged between two trees. The hens were found the next day sitting on their eggs in the chicken house, with no windows broken, as though nothing had happened. |
SEPTEMBER 21ST, 1938 |
The Great Hurricane of 1938, one of the worst storms in U.S. history, strikes an unexpecting and unprepared New England and other Eastern Seaboard areas. After a devastating landfall in Long Island, the storm lays waste to 40,000 square miles across New York and New England; 600 lose their lives as losses soar to over $350 million, including the destruction of 20,000 homes and 26,000 automobiles. |
SEPTEMBER 20TH, 1845 |
The Adirondack Tornado cuts a 275 mi (443 km) swath from Canada to New York, leaving waterspouts whirling on Lake Ontario and Lake Champlain and windfall damage in forests that was still visible over a century later. |
SEPTEMBER 20TH, 1967 |
Hurricane Beulah moved into South Texas, and torrential rains from the hurricane turned the rich agricultural areas of South Texas into a large lake. Hurricane Beulah also spawned a record 115 tornadoes. |
SEPTEMBER 19TH, 1947 |
The eye of a hurricane passed directly over New Orleans, and the barometric pressure dipped to 28.61 inches. The hurricane killed fifty-one persons, and caused 110 million dollars damage. It produced wind gusts to 155 mph while making landfall over Fort Lauderdale FL two days earlier. |
