Hurricanes to hit Google 
People in danger zone could check the threat at their homes

MIAMI - Americans in the hurricane danger zone may soon be able to use
Google to find out if their own home is threatened by a dangerous storm
surge, the director of the National Hurricane Center said on Wednesday.

Storm surge, the massive wall of water carried onto land by a hurricane, is
considered perhaps its most destructive element and greatest threat to the
lives of people who ignore evacuation orders in vulnerable coastal areas.

Bill Read, who was appointed head of the Miami-based U.S. forecasting center
in January, said a planned program will couple a Google application with
storm surge data that meteorologists have used for years to determine the
flooding threat from any category of storm.

"People can plug in their address and see at what level they are at risk,"
Read told Reuters in an interview.

He said he hoped the program would be available during the coming Atlantic
hurricane season, which runs from June 1 to November 30.

Data gathered during Hurricane Katrina, which killed 1,500 people and caused
$80 billion damage on the U.S. Gulf Coast in 2005, found the storm surge
reached up to 22 feet above normal sea level in eastern Mississippi.

Hurricane Andrew, the destructive Category 5 storm that hit the Miami area
in 1992, pushed at least 16 feet of water ashore south of the city.

The damage a storm can cause is largely dependent on its storm surge, and
whether it hits a city or a sparsely populated area. Despite the
catastrophic damage of Katrina, New Orleans was spared the worst of the
surge.

"With Katrina, 30 miles to the west and everything that happened in New
Orleans in two days would have happened in a matter of hours because the
surge would have been much worse and it would have overtopped the levees,"
Read said.

Hurricane forecasters use a computerized model called SLOSH (Sea, Lake and
Overland Surges from Hurricanes) that estimates storm surge heights by
taking into account the size, internal pressure, forward speed, track and
wind strength of a hurricane.

The idea to make it available to the public evolved from calls that inundate
local emergency managers and weather forecast offices every time a hurricane
threatens. Read said people ask what flooding will be like at their house.

"We're not going to know that off the top of our heads," he said. "So we can
say 'go to our Web site, go to such and such, and it's there."

Hurricane forecasters will also offer a new color-coded graphic on the NHC
Web site this year that will indicate storm surge probabilities for
threatened areas, similar to forecasts they now offer on wind-speed
probabilities.


The graphic will indicate the probability of the surge reaching or exceeding
five feet within a given number of hours, Read said.

The graphic promises to help local emergency managers with key decisions
such as when to lock down bridges and which roads could be washed out or
need to be cleared.
