TUCSON -  The National Weather Service office in Tucson conducted a storm survey in response to the landspout tornado that was spotted in Marana on Friday evening.

Meteorologists conducted the survey near Sandario Road and Clark Farms Boulevard and concluded that the tornado lasted for about 5 minutes from 6:55pm to 7:00pm.

The crews found that it was about 10-15 yards wide at its peak and there was no structural damage to report but there was some farm related materials scattered around the area.

The wind was estimated to be around 65mph giving it an EF-0 rating on the Enhanced Fujita scale.

With a landspout tornado, rather than the tornado dropping from the base of the storm, the rotation started on the ground. Then, the ground rotation was sucked into the storm from an updraft. It was the first tornado in the Tucson areas since August 29, 2015.
