Several homes were destroyed and at least three people were hospitalized after severe storms rolled through North Texas, spawning three EF0 tornadoes Tuesday morning.

The damaging storms rolled through Johnson County, just south of Fort Worth, at about 3:40 a.m. CST, but the National Weather Service did not issue severe thunderstorm or tornado warnings. The worst of the damage was just west of Joshua, an NWS damage survey revealed.

Chief James Woolard told NBC Dallas-Fort Worth as many as five homes were damaged by the storm , and neighbors were looking after the pets left behind as two of the injured residents were taken to the hospital. One of the victims was in serious to critical condition, the report added.

"This is the most extensive damage we've seen," he told NBCDFW.com.

Two of the three injuries were sustained when a house collapsed on two women inside, and both needed to be pulled from the rubble, NBCDFW.com also said.

"We asked her where her mother was and she pointed to the direction of the back room of the house," neighbor Jennifer Chezem told NBCDFW.com. "So we went to go to try to find her and we were able to locate her foot and my husband was able to start digging debris off of her to get her out."

The NWS confirmed two separate EF0 tornadoes in Johnson County: one near Joshua, and another near Godley. Both had maximum wind speeds of 80 mph or less.

This is the second time in less than a week that a twister caused damage in the United States without a tornado warning issued; an EF1 tornado hit Uniontown, Pennsylvania , Thursday evening, but that storm had a severe thunderstorm warning. Only a significant weather advisory was issued before Tuesday morning's storm in Johnson County.

A significant weather advisory is issued by an NWS office for thunderstorms that can be impactful, but are not expected to reach severe thresholds, said weather.com senior meteorologist Jonathan Erdman .

The NWS issues severe thunderstorm warnings for those storms which are expected to produce wind gusts of at least 58 mph, wind damage or hail at least 1 inch in diameter, he said.

Additional damage was reported Tuesday morning in DeSoto, just south of Dallas. The NWS confirmed a third EF0 tornado, which damaged some 30 homes.

More than 8,000 Oncor customers lost power during the storms, the utility company said.
