MIAMI -- The busiest and costliest Atlantic hurricane season on record officially -- and mercifully -- draws to a close today, with hundreds of thousands of Americans still dealing with the devastation wrought by Katrina, Rita, and Wilma.
Despite the end of the season, which runs from June 1 to Nov. 30, hurricanes could still form over the next few months. In fact, a tropical storm took shape in the Atlantic yesterday, but no hurricane has been known to hit the United States between December and May.
And that is welcome news, particularly along the Gulf Coast, where Katrina hit three months ago, plunging New Orleans into the kind of chaos usually seen in the Third World, exposing the gap between rich and poor, and raising serious doubts about the country's readiness for another catastrophe, caused by man or nature.
The relief may not last very long: Forecasters say 2006 could be another brutal year because the Atlantic is in a period of frenzied hurricane activity that began in 1995 and could last another decade.
Government hurricane specialists say the increase is due to a natural cycle of higher sea temperatures, lower wind shear, and other factors, though some scientists blame global warming.
The 2005 season obliterated many longstanding records:
In 154 years of record-keeping, this year had the most named storms (26, including Tropical Storm Epsilon, which formed yesterday), the most hurricanes (13), the highest number of major hurricanes hitting the United States (4), and the most top-scale Category 5 hurricanes (3).
Katrina was the deadliest US hurricane since 1928 (more than 1,300 dead) and replaced 1992's Andrew as the most expensive one on record ($34.4 billion in insured losses).
The total insured losses from hurricanes this year were put at $47.2 billion, above the previous record of $22.9 billion set last year when four hurricanes hit the United States, according to risk-analysis firm ISO.
Wilma was briefly the most intense Atlantic hurricane on record in terms of minimum central pressure (882 millibars). It also was the fastest-strengthening storm on record -- its top sustained winds increased 105 miles per hour within 24 hours in the Caribbean.
Forecasters exhausted their list of 21 proper names and had to use the Greek alphabet to name storms for the first time.
The worst damage, of course, was inflicted by Katrina. Miles of coastal Mississippi towns such as Waveland and Gulfport were smashed. Eighty percent of New Orleans was under water after its levees broke. The world saw families stranded on roofs and hungry and thirsty refugees stuck in the Superdome and convention center. Bodies lay on streets for days or floated in the fetid flood waters. Hundreds of thousands of people have yet to return to their homes -- or have no homes to return to.
So far, Congress has approved $62 billion in mostly short-term relief aid, and estimates put the cost of rebuilding at up to $200 billion.
The Bush administration was bitterly criticized for its slow response to Katrina. Michael Brown, director of the Federal Emergency Management Agency, lost his job, and the president's approval ratings sank.
Wilma, Dennis, and Rita, the other hurricanes that hit the United States, were not as deadly or destructive, but they also exposed weaknesses: There were 14-hour traffic jams as Houston emptied out ahead of Rita, which struck the Texas-Louisiana coast Sept. 24, and South Florida was crippled after Wilma knocked out power to more than 6 million people Oct. 24.
The president has ordered the Homeland Security Department to review disaster plans for every major metropolitan area. FEMA is also pledging to manage the flow of personnel and supplies better.
''We have to make it a much more nimble, more adaptable organization. . . . We've got good people in place to make it happen," said R. David Paulison, FEMA's acting director. He added: ''As long as I'm here, I can tell you, we will not have another Superdome."
Despite government warnings that people be prepared to survive on their own for three days after a catastrophe, polls suggested that a majority of Americans are no better prepared for a disaster than they were before Katrina.
''The biggest thing that can be done to prevent loss of life is to motivate people to develop their own individual hurricane plan and know what to do before the next hurricane," said Max Mayfield, director of the National Hurricane Center, which won praise for its accurate forecasts. ''Some of these folks, take Mississippi in Katrina, they died because they didn't have a hurricane plan."
But some Americans have learned their lesson.
''Next time they say evacuate, I'm gone," said Tracy Haywood, 38, of New Orleans, who spent three days stranded on a roof during the storm before being rescued.
