NOAA
PROVIDES WRAP-UP ON VERY ACTIVE 2004 ATLANTIC HURRICANE SEASON
Nov.
30, 2004 � The 2004
Atlantic hurricane season was one for the record books, say NOAA
hurricane and climate prediction specialists. Nine named storms affected
the United States during the six-month hurricane season—three
as tropical storms (Bonnie, Hermine and Matthew) and six as hurricanes
(Alex, Charley, Frances, Gaston, Ivan and Jeanne). Three of the hurricanes
(Charley, Ivan, and Jeanne) made landfall as major hurricanes. Nature's
favorite target this season was the state of Florida, which was affected
by four hurricanes and one tropical storm. (Click NOAA satellite

"During
late summer it seemed that each day's headlines highlighted the impact
of this hurricane season," said Brig. Gen. David
L. Johnson, U.S. Air Force (Ret.), director of the NOAA
National Weather Service. "Property damage was significant,
but in the United States, loss of life—while always tragic—was
minimized due in large part to heightened public awareness, preparation
and response to our forecasts of these dangerous tropical systems."

NOAA's
seasonal hurricane outlook issued in May called for 12 to 15 named storms,
six to eight hurricanes and two to four major hurricanes. The season
actually produced 15 named storms, of which nine became hurricanes,
and six became "major" (Category 3 or higher on the Saffir-Simpson
Hurricane Scale). In the month of August alone, eight systems reached
tropical storm strength, breaking the previous record of seven in 1933
and 1995. The annual outlook is the work product of the combined efforts
of NOAA's Climate Prediction
Center, Hurricane Research Division
and the National Hurricane Center.
"What
could not be anticipated this season was the high number of U.S. landfalling
hurricanes," added Johnson. On average, the U.S. experiences two
to three landfalling hurricanes during above-normal hurricane seasons,
well below the eight landfalls recorded this year (Alex is not officially
counted as a landfall since the center of its eye remained offshore).

This is
the first time since record-keeping began in 1851 that four hurricanes
have impacted Florida in one year. The only other state to have experienced
this level of activity was Texas in 1886. Hurricane Ivan was an encore
performer with two landfalls during 2004, first as a Category 3 hurricane
near Gulf Shores, Ala., and second as a tropical storm over southwestern
Louisiana.
Human
and economic impacts were considerable. Direct U.S. hurricane-related
fatalities totaled 59. Florida bore the brunt of U.S. property damage,
with damage estimates (adjusted to year 2000 dollars) expected to eclipse
the $34.9-billion in damage caused by Hurricane Andrew in 1992. The
Insurance Information Institute estimates that one in every five Florida
homes was impacted by a hurricane to some degree this year. Some 9.4
million Florida residents were evacuated from their homes this season.

Scientists
point to the multi-decadal fluctuations in seasonal activity as a primary
factor leading to the high number of hurricanes during 2004. During
1995-2004 eight of ten Atlantic hurricane seasons were above normal
(the exceptions being the El Niño years of 1997 and 2002), increasing
the potential for more landfalling hurricanes. During 2004, the hurricane
landfalls were also related to a strong region of high pressure over
the western Atlantic in the middle levels of the atmosphere, which helped
to steer hurricanes toward the United States rather than out to sea.
"The
2004 season was one to tell your grandchildren about," said Max
Mayfield, NOAA's National Hurricane Center director. "I believe,
and stress at every opportunity, that residents should have a plan,
stay informed and act when told to do so by their local officials. We
should mark November 30th not as the end of the 2004 hurricane season
but the beginning of the six months we have to prepare for next season."
