Carr Fire Latest: Here's What You Can Do to Help

The Carr fire in Northern California has already burned more than 48,000 acres of land, destroying 500 structures and killing six people as of Monday morning, the local sheriff announced.

The fire intensified at the tail end of last week, doubling in size overnight on Friday. Authorities had contained only about 5 percent of it by Sunday morning. Authorities discovered a sixth victim of the blaze at a burned home, Shasta County Sheriff Tom Bosenko told The Associated Press, without revealing the person's identity. The department is also investigating seven missing persons reports.

The fire was one of 17 significant blazes across California on Sunday, meaning 50,000 have had to evacuate and authorities are busy on several fronts, deploying 12,000 firefighters to battle the infernos, according to Lynne Tolmachoff, a Cal Fire spokeswoman.

While donations of water, blankets and other items are accepted by some relief agencies, monetary donations are collected most widely, according to the Emergency Operations Center, set up by the governor's office. "Money donations are the easiest to manage and provide the means to purchase the exact items in need," Emergency Operations Center spokeswoman Amy Travis said, according to the Statesman Journal.

The American Red Cross is collecting donations to help those affected by the fire as part of its disaster relief fund. Donors can give to the organization, supporting its work across the country, or they can designate that they wish their money to go specifically toward relief against the fires in California, the organization said on its website. By texting "REDCROSS" to 90999 you can make a $10 donation to the charity, in whose shelters 620 people have sought overnight refuge. The organization also accepts donations by check, via the nearest American Red Cross chapter, or by filling out an online form. Making a donation this way allows you to ensure the money goes toward relief from a specific disaster by writing the disaster name in the memo line of the check, as Red Cross promises to honor donor intent.

Other ways to donate money include the United Way of Northern California. You can donate to the Shasta County Fire Relief Fund by texting "CARRFIRE" to 91999. Or you can visit the organization's website and the Shasta Regional Community Foundation's Community Disaster Relief Fund, which is collecting money on behalf of regional nonprofits. Crowdfunding website GoFundMe has also published a running list of verified campaigns that claim to support individual families rendered homeless by the fire.

The Salvation Army of Northern California is also collecting donations online, promising that "100 percent" of the gift will go to fire-relief efforts. The Haven Humane Society is also asking for money donations, animal food and supplies on Facebook as it continues to shelter lost or displaced pets as a result of the fire.
