A storm that added to record amounts of rain in the Puget Sound region Monday also spawned a rare tornado in the Frederickson that damaged buildings and railroad cars. No injuries were reported.
AccuWeather.com reported that the EF-1 tornado, packing wind up to 110 miles per hour, traveled one mile before dissipating. Rail cars sitting on tracks in an industrial area were tipped over.
An EF-1 is the second-lowest category of tornados in terms of wind speed. The highest is an EF-5 at 200 miles per hour or more.
The storm on the final day of September helped shatter the previous record of rainfall in Seattle and other locales, according to AccuWeather.com. Seattle finished the month with 6.21 inches of rain, with about half of it falling in the last few days. The old record of 5.95 inches was set in 1978.
Approximately 1,300 tornadoes are reported per year in the United States, according to NOAA (National Oceanic and Atmospheric Administration). They rarely occur in Washington and generally cause relatively minor damage.
