WOODWARD, Okla. - Another person has died from injuries sustained in Sunday's deadly tornado in Woodward, Okla., officials say.
The latest loss brings the death toll to six. At least three of those victims are children.
Woodward County Emergency Management Spokesperson Matt Lehenbauer said the latest victim, a man, died in the hospital after suffering severe injuries during the storm. The man's wife is still listed in critical condition.
Dozens more were injured as a EF2 tornado tore through the town just after midnight Sunday.
Woodward Mayor Roscoe Hill said warning sirens sounded loudly Saturday afternoon when storms rumbled through but he didn't hear the sirens go off before Sunday's tornado.
"We had a little tornado earlier ... and they blew all the sirens. When this one came in, our sirens weren't working," Hill said.
The high winds damaged homes, toppled trees and downed power lines in the area about 140 miles northwest of Oklahoma City.
The victims' identities have not been released.
A team of six volunteers from the Tulsa Regional Chapter of the American Red Cross set off for Woodward Monday morning to assist with relief operations.
They will work alongside other Red Cross volunteers who have been on scene since just after the storms hit.
Meanwhile, Gov. Mary Fallin has declared a state of emergency for 12 Oklahoma counties due to tornadoes, severe storms, straight line winds and flooding.
The counties include Alfalfa, Caddo, Canadian, Cleveland, Ellis, Harper, Jackson, Kiowa, Logan, Oklahoma, Woods and Woodward.
A swath of tornadoes erupted across the Midwest and Plains. Storms were reported in Kansas, Iowa and Nebraska as a severe storm system made its way across the middle of the country Saturday and Sunday.
