Learning Lessons From The Dallas Storm

The tornadoes that touched down on Saturday were the deadliest to strike the Dallas/Fort Worth area since 1927 and they’re likely to be the subject of study by emergency planners and disaster responders for years to come.

Some valuable lessons have already come out of the disaster: The outdoor tornado sirens might have been useless to the eight people who were killed when their cars were hit by a twister and blown off a highway overpass.

ABC’s Jim Ryan has been talking with emergency specialists, and as well can update the latest developments regarding the storm system.
