A third tornado hit Cape Cod last week, the National Weather Service confirmed Monday, this narrow one briefly touching down at the same time as another tornado.
Officials had previously said that two tornadoes tore through part of the region on July 23.
It was an EF-1 tornado, the same rating as the other two, that packed 90 mph winds.
It traveled a quarter mile in West Yarmouth from Yacht Avenue and Schooner Street to Egg Harbor Road and lasted one minute, causing mainly damage to trees.
The update from the NWS comes after TV meteorologists, area residents and amateur radio observers reported additional information, according to the weather service's report.
Last week, NBC10 Boston Chief Meteorologist Matt Noyes documented tornado damage on the ground at that location. (See video atop this story.)
The NWS update noted that, before Tuesday, there had only ever been three tornadoes documented touching down on Cape Cod: in 2018, 1977 and 1968.
The tornadoes caused heavy damage in a concentrated part of Cape Cod but no deaths or major injuries.
