A year after one of the worst winters in decades, emergency officials say St. Louis is prepared for more severe weather. City and county officials were briefed Thursday on the American Red Cross's preparations at its national disaster warehouse in north St. Louis.
Mary Anderson, the Red Cross' regional director of disaster services says since last year's devastating tornados that struck Missouri, the Red Cross is making space in the 100,000 square-foot facility for more supplies.
