great deal of damage. you talk about the city of houston alone. the city, one-third of it, remains under water at this point. staggering statistic there. one military official telling cnn that it's unclear how many people are in need of rescue. the houston fire department going door to door canvassing to find out if they have any more to do in the neighborhoods. neighborhoods near rivers that ton rise. neighborhoods near bayous and tributaries, still a problem. beaumont, texas, the u.s. navy has been conducting search and air resktcues. they airlift 25 men, women, and children. the search efforts continue day by day, hour by hour. one interesting statistic, guys, that puts this storm into perspective. it broke a weather record. it dropped 52 inches of rainfall
