The National Weather Service said an EF4 tornado tore through Garland and an EF3 tornado cut a path through Rowlett. On Sunday, the NWS reported that damage in Copeville, on the east side of Lake Lavon in Collin County, was consistent with an EF2 twister.

The NWS also reports separate EF0 tornadoes in Blue Ridge, south of Sulphur Springs, northeast of Emory, northeast of Eustace, and in Hubbard. NWS survey crews are also working to assess the damage in the Ovilla/Glenn Heights area.

The devastation came into focus Sunday in North Texas, where local officials estimated as many as 1,450 homes were damaged or destroyed. Vehicles were mangled, power lines had fallen and trees were toppled. The storm blew the roofs off homes and caused natural gas lines to burst. Heavy rain, wind and dropping temperatures hampered cleanup efforts Sunday afternoon.
