A sixth person died after devastating tornadoes swept across Oklahoma over the weekend, local officials said Monday.

The latest victim was believed to be a seriously injured man who died in the hospital overnight after Woodward, Okla., was struck by a tornado, Fox affiliate KOKH-TV reported.

Two men and three children also died when a twister nearly a quarter mile wide tore across the city of 12,000 early Sunday and continued on through Tangiers, located 67 miles west of Woodward.

Of those victims, one man and his two young daughters were killed when the tornado ripped through a trailer park.

Around 30 other people were hurt as a result of the severe weather conditions, KOKH reported.

As the cleanup efforts were set to begin Monday, local news reports showed TVs, microwaves and vacuum cleaners among the debris strewn across what remains of the trailer park.

Church groups and volunteers were ready to assist with the cleanup operation as most of the area saw its electricity working once more. The worst-hit areas were still without power, according to the report.

The Red Cross set up a relief shelter at a local church for those displaced by the storms.

Woodward police chief Harvey Rutherford told KWTV that a tower designed to send a repeating signal to the city's tornado siren system was disabled by the storm, which meant that many residents received no warning of the approaching predawn twister.

Roughly 120 tornadoes were spotted across Kansas, Nebraska, Oklahoma and Iowa over the weekend.

Most of those sightings were in Kansas, where one half mile-wide wedge tornado came close to hitting downtown Wichita.
