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)
