The year 2014 will go down as a wet and record warm year as well as a tragic year. There were 50 weather-related fatalities capped by the 43 involved with the SR-530 slide on March 22. There were also three avalanche and wind-related fatalities each, as well as a rip current fatality. Nineteen people were injured during the year and weather-related damage totals through October were in excess of $64 million.
It was a record warm year with about a week left before the end of it. The average temperature at Sea-Tac Airport was 55.5 degrees, exceeding the previous record of 54.4 degrees in 1995. The average high temperature was 63.1 degrees exceeding the record of 62.5 degrees in 1992. The average low temperature was 47.9 degrees exceeding the record warm low temperature average of 46.7 degrees set in 1995 and 2013.
Through Dec. 22, there have been only 83 days (23 percent) with below normal temperatures. Since July 1, the percentage is even lower with only 27 days below normal (15 percent).
There were plenty of warm nights in Seattle in 2014. Through Dec. 22, there were 176 days with a low temperature of 50 degrees or more. This is a new record and crushes the old record of 157 days set in 1995.
