Hurricane Katrina's effects, at a glance:
—Deaths: The mayor said the hurricane probably killed thousands of people in New Orleans — an estimate that, if accurate, would make the storm the nation's deadliest natural disaster since at least the 1906 San Francisco earthquake. Relief crews put aside the counting of bodies to concentrate on rescuing the living, many trapped on rooftops and in attics.
—Estimated 80 percent of New Orleans (search) under water, up to 20 feet deep in places. Water still rising as engineers struggle to plug two breached levees along Lake Pontchartrain with giant sandbags.
—Authorities drew up plans to clear out the tens of thousands of people left in the Big Easy and all but abandon the flooded-out city. Many of the evacuees — including thousands now staying in the Superdome — will be moved to the Astrodome in Houston, 350 miles away.
—Lt. Gov. Mitch Landrieu (search) said 3,000 people rescued by boat and air.
—Sections of Interstate 10, only major freeway leading into New Orleans from the east, destroyed.
—At least 713,000 customers estimated without power.
—BellSouth Corp. (search), the region's dominant local phone provider, estimated that about 750,000 lines may be out of service in the most heavily damaged areas.
—Looting broke out in some New Orleans neighborhoods. Thieves took guns from a Wal-Mart. One police officer shot in the head by looter but expected to recover. Looters also used a forklift to smash open a pharmacy. City officials themselves commandeered equipment from a looted Office Depot. During a state of emergency, authorities have broad powers to take private supplies and buildings for their use.
