As the biggest search and rescue effort in Texas history begins, national and community aid organizations are calling on all Americans to donate money and muscle to victims of Hurricane Ike.

The American Red Cross has more than 20,000 people in evacuation shelters across four states, providing beds, blankets, toiletries and emotional support to evacuees. It is stockpiling provisions for distribution posts and has 25 to 30 mobile kitchens on hand able to serve up to 500,000 meals per day.

It’s also bringing extra units of blood to North Texas.

The Red Cross encourages evacuees to register with its Safe and Well Web site which helps family and friends reconnect in emergencies. Visit disastersafe.redcross.org.

The Salvation Army deployed five mobile disaster response units to Galveston, Lufkin and Beaumont, Texas, in association with the National Guard. Three 48-foot mobile kitchen units and a convoy of more than 60 canteens are part of the association’s long-term response “strike teams,” the Salvation Army’s biggest operation since Gustav. Throughout Texas, the association is helping the evacuation and shelter effort and is calling for volunteers and for monetary donations to provide $100 in food, water and household clean-up kits to flood victims.
