November 30 officially marked the end of the
2006 hurricane season. In comparison to the two seasons before
— 2004, the year of Charley, Frances, Jeanne, and Ivan; and
2005, the unforgettable year of Katrina, Rita, and Wilma — it
was downright calm. But to the National Hurricane Center, it was
"near normal." A normal season, as defined by the National
Hurricane Center, has six to 14 named storms, with four to eight of
those reaching hurricane strength, and one to three "major"
hurricanes reaching Category 3 or higher. This past season there
were, in fact, nine named storms, five of which reached hurricane
status. But only one — Hurricane Helene — reached
Category 3, and all weakened below hurricane status before making
landfall.
Thankfully. Coastal residents, particularly those along the ravaged
Gulf Coast, where life is still far from normal, can all draw a
collective sigh of relief for having dodged a bullet this year. It
provides much-needed time for those rebuilding after Katrina to
continue their efforts. We need that time to continue assessing
what went wrong in 2005.
There are two primary conclusions to be drawn from the apparent
lull of 2006. The first is that it's decidedly unwise to draw any
conclusion about long-term weather patterns based on the outcome of
one storm season. Hurricane researchers still insist we are in a
cycle of high storm activity. This past year, just as many
low-pressure systems formed, and water temperatures in the Atlantic
remained high enough to kindle plenty of storm activity. However,
strong winds blowing from the Pacific created enough shear to
disperse high-level clouds and prevent the storms from building to
any size. That points to the likelihood that we can expect more
action next season. If anything, the statistical ante has just been
raised.
There is another thing to bear in mind: If you were working in
Nantucket in July when tropical storm Beryl grazed the island, or
near Long Beach, N.C., at the end of August when Ernesto blew
ashore, or on the south coast of Newfoundland when the tail end of
Florence inundated homes with driving wind and rain, the 2006
season was still intense (likely even more so than the year
before). That's especially true for the couple killed in
Gloucester, Va., when Ernesto blew over a tree that crushed their
house, or the family in Franois, Newfoundland, whose home
was blown into the surf by Florence.
Too often the generalizations of science are misreported or
misunderstood. Hurricanes, like house building, are local events,
and life on the coast will always have to contend with gale-force
winds, lashing rains, short wetting and drying cycles, elevated
humidity, salt spray, and a risk of flooding, all of which present
a threat to homes. Best we prepare for it.
