Six people are dead and seven still unaccounted for in Granbury. The Rancho Brazos neighborhood torn apart by a tornado will remain closed until officials can account for everyone who lived there.
An outbreak of as many as 16 tornadoes slammed through several small communities in three North Texas counties after sundown Wednesday, killing two women and four men while injuring more than 100 others.
Seven people in Granbury, the hardest-hit community, are still missing. But Hood County Sheriff Roger Deeds said he is confident they simply haven't checked in with authorities yet. Officials won't know for sure until every piece of debris is turned over, he said.
The violent spring storm scattered bodies and threw trailers onto cars while leaving many, possibly hundreds, homeless in Granbury and Cleburne after an untold number of houses were reduced to nothing more than a concrete slab and a pile of rubble.
The National Weather Service said Thursday that preliminary damage estimates indicated an EF-4 tornado with wind speeds between 166 mph 200 mph touched down in Granbury and an EF-3 tornado with wind speeds between 136 mph and 165 mph later touched down in Cleburne.
The highest rating on the EF scale is an EF-5, which has wind speeds in excess of 200 mph.
Granbury's Rancho Brazos Estates neighborhood, an area constructed in recent years by Habitat for Humanity volunteers, was hit the hardest and is where the six fatalities and a vast majority of the injuries occurred.
"Some were found in houses. Some were found around houses," Deeds said. "There was a report that two of these people that they found were not even near their homes, so we're going to have to search the area out there."
Officials said Thursday that Glenda Whitehead, Bob Whitehead, Tommy Martin, Jose Tovar Alvarez, Marjari Davis and Leo Stefanski were killed in the storm.
One of the Habitat for Humanity homes that was destroyed was supposed to be dedicated to a family on Saturday.
Both the DeCordova Ranch and Rancho Brazos neighborhoods, where 97 of the 110 homes in the neighborhood are damaged or destroyed, remain sealed off to the public. Deeds said residents attempting to salvage personal belongings would only be allowed back in the neighborhoods once hazards such as downed power lines and compromised gas lines are repaired or removed.
In Cleburne, east of Granbury, storm spotters told the NWS a tornado that was estimated to be a mile wide tore through the town Wednesday night. NWS officials later determined the Cleburne tornado to be an EF-3 with winds up to 165 mph. Mayor Scott Cain said early Thursday that no one was killed or seriously hurt in Cleburne, although seven people suffered minor injuries. He estimated that dozens of homes were damaged and declared the area a local disaster.
Meanwhile, the Red Cross has opened two shelters at local Granbury churches where they are providing services to residents. Additionally, victims of the storm can receive assistance from the Red Cross by calling 866-505-4801.
Across North Texas, utility companies said about 20,000 homes and businesses were without power early Thursday morning due to the storms. By mid-morning, that number had dropped to about 15,000 customers.
The number of confirmed tornadoes may change in the coming days as the NWS continues their investigation.
