A crisis is unfolding in the mountains of western North Carolina, where water, food and other supplies are being airlifted into places cut off by mudslides and washed-out roads.

North Carolina Governor Roy Cooper is encouraging donations to the North Carolina Disaster Relief Fund, set up to help residents recover from the damage. The funds will be administered by United Way of North Carolina, with the money going to nonprofits working to meet the immediate needs of storm victims and clean up and emergency supplies.

The full impact of Hurricane Helene won't be known for weeks, but groups from both the public and private sector are mobilizing efforts to help those affected by the Category 4 storm that has killed at least 120 people and already caused billions in damage.
