NORTH TEXAS (CBSDFW.COM) — Residents have been on high alert as tornado warnings, and at least one tornado that storm chasers say touched down, moved through the Dallas area Saturday. A tornado watch was put into effect for North Texas until 8 p.m. early in the day and then was extended to 11 p.m.

A very preliminary count indicated 11 tornadoes hit the Dallas area Saturday evening, according to the National Weather Service. That number is likely to change.

Around 5 p.m., four separate storms had tornado warnings. Watch the live stream of storm coverage here.

Storms moved north through Dallas, causing the National Weather Service to initiate more and extend existing tornado warnings. Around 7:30 p.m., Oncor reported 346 active outages affecting 70,427 customers.

Ground stops were put into effect at Love Field and Dallas-Fort Worth International Airport. Security at other areas, such as the NorthPark Center, told people to shelter in place.
