DRONE DAMAGE VIDEO: 30 treated at Tulsa hospital after tornado

TULSA, Okla. (AP) - St. Francis Hospital spokeswoman Lauren Landwerlin says about 30 people have been treated at the hospital's trauma center and three were admitted in "non-critical condition" after a tornado struck near midtown Tulsa.

The figure of 30 injured is up from 13 initially reported taken by ambulance to hospitals. A city spokeswoman says many people were taken to hospitals by private vehicles.

No deaths are reported.

The city may have been fortunate because the tornado struck just after 1 a.m. Sunday and most stores and restaurants were closed in the shopping district.

National Weather Service meteorologist Amy Jankowski said preliminary reports indicate a tornado, but it could be Monday before surveyors complete their investigation.

Jankowski said tornadoes are generally associated with spring months and said an August tornado is uncommon, but not "outrageously rare."
