At least four people died after a tornado outbreak hit Oklahoma late Saturday night, with Sulphur, Marietta and Holdenville suffering the most damage.KOCO 5 Chief Meteorologist Damon Lane says the report from the National Weather Service shows that at least 22 tornadoes hit Oklahoma on Saturday, and that number could rise. On Sunday afternoon, the National Weather Service released the preliminary ratings for tornadoes across the state. However, damage surveys are ongoing. An EF3 tornado was confirmed in Sulphur. Further investigation is necessary to determine if the rating will go higher, according to the National Weather Service. In Marietta, preliminary reports rated the tornado an EF3, but it was later raised to an EF4. An EF0 was reported in both Stillwater and Newkirk. Storm damage has been reported from northern Oklahoma down to the Red River. At least two people, including a 4-month-old, died when a tornado went through Holdenville in Hughes County. Another person was found dead in the debris in downtown Sulphur, according to Gov. Kevin Stitt, and a fourth person died on Interstate 35 in Marietta. At least 100 others were injured across the state, according to the Oklahoma Department of Emergency Management. Authorities will continue assessing damage in Holdenville and Sulphur, where KOCO 5 crews saw leveled buildings and vehicles impaled by debris. Gov. Kevin Stitt issued a statement early Sunday morning, saying, "My prayers are with those who lost loved ones as tornadoes ripped through Oklahoma last night. Thank you to Oklahoma Emergency Management and those who have worked through the night to keep Oklahomans safe and have worked to clear debris and assess damage."
