Kosciusko County American Red Cross chapter volunteer Mary Hoffer is deploying for Colorado on Tuesday to assist as a staff wellness nurse for those affected by flooding.

Hoffer is a registered nurse who is volunteering for her third deployment in 14 months.

Four deaths have so far been confirmed on historic flooding in Colorado, but more than 500 people remained unaccounted for in Boulder and Larimer counties as of Sunday night. President Barack Obama declared the area a federal disaster over the weekend.

According to a statement provided by Army spokesman Major Earl Brown U.S. National Guard and U.S. Army troops have rescued 1,750 people cut off by washed-out roads in the mountain canyons.

The best and quickest way to help Colorado flood victims is to donate to the American Red Cross disaster relief fund online. Donations of $10 can also be made via by texting “REDCROSS” to 90999. Of every dollar donated, 94 cents goes directly to helping victims of disaster. The Red Cross relies on the generosity of volunteers and donors to carry out the mission of providing immediate needs to victims of disaster.
