1965
The temperature soared to 104 degrees at San Diego, CA. Southern California was in the midst of a late October heat wave that year. Los Angeles had ten consecutive days with afternoon highs reaching 100 degrees. (David Ludlum) (The Weather Channel)

1985
A guest on the top floor of a hotel in Seattle, WA, was seriously injured while talking on the phone when lightning struck. Several persons are killed each year when the electrical charge from a lightning bolt travels via telephone wiring. (The Weather Channel)
