-From reporter Maddie Garrett at the Texoma Chapter of the American Red Cross on FM 691 in Denison:

The Red Cross's HAM radio tower snapped and fell around 4:15 p.m. Monday due to sudden strong winds. The storm knocked over the tower, which is about 50 feet tall, and then fell onto power lines connected to the Red Cross building located on FM 691 in Denison.

Red Cross director Sharon Watson said they heard the loud crash and figured it was trees falling over.

The Denison Fire Department responded to make sure the building was safe and there were no fire hazards. ONCOR electric also came out to cut off all power so they could begin work on the fallen radio tower.

The HAM radio crews will then be able to safely take apart the tower. Watson said no one was injured in the storm, but they will also check for damage to their roof.

The Red Cross also said they had been thinking about shortening the tower because it was on an elevated hill to begin with.

More on the power outages at Loy Lake & Gallagher from reporter Maddie Garrett:

4 power poles down. This is a major transmission line. Knocked out power to customers on Texoma Pkwy and east of US Hwy 75. High winds also knocked down power lines in central and south Sherman, as well as the downtown area. Those power lines interrupted communication between Sherman Fire and Police. They've since switched to an emergency generator so there was no loss of service.

Sherman Fire repsonded to over 30 calls, most of them concerning downed power lines. No injuries have been reported.

ONCOR crews are out working at this hour. They say all power should be restored by 10 p.m.
