OCTOBER 21ST
HISTORIC WEATHER EVENTS
...1934...
A severe windstorm lashed the northern Pacific coast. In Washington State,
the storm claimed the lives of 22 persons, and caused 1.7 million dollars
damage, mostly to timber. Winds, gusting to 87 mph at North Head WA,
produced waves twenty feet high. (David Ludlum)
...1957...
The second in a series of unusual October storms hit southern California
causing widespread thunderstorms. Santa Maria was drenched with 1.13 inches
of rain in two hours. Hail drifted to 18 inches in East Los Angeles.
Waterspouts were sighted off Point Mugu and Oceanside. (20th-21st) (The
Weather Channel)
...1987...
Cold arctic air continued to invade the central U.S. Eleven record lows
were reported in the Great Plains Region, including lows of 12 degrees at
Valentine NE, and 9 degrees at Aberdeen SD. Temperatures warmed rapidly
during the day in the Southern and Central Plains Region. Goodland KS
warmed from a morning low of 24 degrees to an afternoon high of 75 degrees.
(The National Weather Summary)
...1988...
Joan, the last hurricane of the season, neared the coast of Nicaragua
packing 125 mph winds. Joan claimed more than 200 lives as she moved over
Central America, and total damage approached 1.5 billion dollars. Crossing
more than 40 degrees of longitude, Hurricane Joan never strayed even one
degree from the 12 degree north parallel. (The National Weather Summary)

Unseasonably cold weather continued to grip the south central and
southeastern U.S. Twenty cities reported record low temperatures for the

to an end, but not before leaving Marquette MI buried under 12.7 inches of
snow, a record 24 hour total for October. (The National Weather Summary)
