Emergency crews are out assessing damage left behind from overnight storms.

The National Weather Service reported evidence of an EF-0 tornado touched down near Watauga and Keller in North Tarrant County.

The severe weather threat ended early Wednesday morning for the immediate Dallas-Fort Worth area as the watches and warnings expired.

What's believed to be the worst of the storm hit the Dalton Ranch subdivision of Rockwall, where multiple homes were damaged and three houses were reportedly destroyed.

The National Weather Service has sent teams to the hardest hit areas -- Rockwall, Benbrook, Keller and Haslet/FlowerMound, to survey damage.
