A series of tornados in northern Texas killed six people and injured more than 100.

The twisters were generated by a storm that hit the town of Granbury in Hood County, southwest of Dallas, on Wednesday afternoon. They destroyed nearly 120 homes in one neighborhood, CNN reported, citing county sheriff Roger Deeds.

As local officials combed through the debris in Granbury assesing the damage and looking for survivors, residents waited to see if their homes had survived.

Granbury, about 40 miles southwest of Fort Worth, bore the brunt of the damage. The National Weather Service's preliminary estimate was that tornado had wind speeds between 166 mph and 200 mph. Other tornadoes spawned from the violent spring storm damaged nearby Cleburne and Millsap.

Deeds told NBC News that 14 people were still missing.

The storm hit a Habitat for Humanity neighborhood in Granbury, destroying a majority of the homes there, Deeds said.

"I tell you, it has just broken my heart," said Habitat volunteer Elsie Tallant.

Hood County Judge Darrell Cockerham told CNN that some of the homes in Granbury had been flattened with people still inside.

An NBC reporter tweeted that searches would resume at daybreak for those missing.

Storm spotters said they saw a mile-wide tornado near the city of Cleburne, east of Granbury.

Matt Zavadsky, a spokesman for MedStar Mobile Healthcare, said the tornado touched down several times in Hood, Tarrant, Dallas and Parker counties, leaving about 100 people injured.

The Dallas Morning News ran photos of what appear to be the beginning stages of tornadoes, as well as damaged homes and an 18-wheel truck tipped over onto a compact car.
