The tornado that ripped through Moore, Okla., Monday afternoon leveled entire neighborhoods and left countless people without homes and schools. Several local and national organizations are accepting donations toward the recovery effort; most stress that monetary donations, not clothes or supplies, are most needed right now.

American Red Cross: The Red Cross is providing shelter, food and relief supplies to people in Oklahoma, Kansas, Iowa and Missouri. You can donate directly to the Red Cross Disaster Relief fund online or by texting “REDCROSS” to 90999. (Texting a donation, to the Red Cross or any of the following organizations, will charge $10 to your cellphone plan.) The organization is also encouraging donors to give blood at their local hospital or blood bank.

Salvation Army: The Salvation Army’s disaster response units plan to serve three meals a day in the areas hardest hit by the tornado. You can donate online or by texting “STORM” to 80888.

Feed the Children: The Oklahoma City-based children’s advocacy group is collecting monetary donations to support tornado relief. Donations can be made online; according to Feed the Children, $50 will buy 375 pounds of relief supplies.

Regional Food Bank of Oklahoma and the Oklahoma Voluntary Organizations Active in Disaster: The two local organizations are soliciting donations for joint clean-up efforts. You can contribute online or by texting “FOOD” to 32333.

Oklahoma Baptist Disaster Relief: This local organization is distributing food and supplies in Shawnee, Carney, Prague and Norman, Okla., as well as aiding in clean-up. While it says “monetary donations are the best help at this point,” it is also accepting bottled water, flashlights, batteries, non-perishable food and some other supplies at collection centers in Oklahoma.

Operation USA: The L.A.-based relief agency is sending emergency, shelter and cleaning supplies to hard-hit areas. Monetary donations can be made online, by phone at 1-800-678-7255, or by texting “AID” to 50555. Operation USA is also soliciting businesses for bulk quantities of disaster supplies and United and Continental air miles.

A number of businesses, churches and community organizations around Oklahoma City have also advertised specific needs, from diapers and toiletries to canned food and medicine. Local TV affiliate KFOR has compiled a list of those organizations.
