HURRICANE GEORGES
AND ITS EFFECTS ON THE
FLORIDA KEYS
Figure
1 is an example of the damage caused by Hurricane Georges as
it passed through the Florida Keys. This picture was taken on Cudjoe
Key, mile marker 23, along U.S. 1. The greatest damage in the Keys
occurred between Cudjoe Key and Big Pine Key, mile marker 30, where
the strongest winds of hurricane Georges were estimated to be 105
mph sustained with gusts to 125 mph. Residents of these areas were
without electricity for approximately 2 weeks. (Click here

Included in this document is a table of the
recorded winds, storm total rainfall amounts, storm surge, and lowest
pressure along the Keys. Estimated damage totals are also shown.
Hurricane Georges was the first hurricane to directly affect the
Keys since 1987 and only the second since 1966. Fortunately, there
were no deaths directly related to the hurricane.
Hurricane Georges approached the Florida Straits
after moving off the shore of the north-central Cuban coast on Sep
24. It maintained its consistent west-northwest movement at 12-15
mph until it neared the Lower Keys. Georges then began to move more
toward the west with the northern portion of the eye moving over
Key West between noon and 1:30PM Sep 25. Georges continued to move
west from Key West with its eye passing over the Dry Tortugas, 65
miles west of Key West. It eventually made landfall again near the
Louisiana and Mississippi coasts after traversing the Gulf of Mexico.
Georges was a minimal category 1 hurricane when
it emerged over the Florida Straits. It gained strength before hitting
the Keys, becoming a minimal category 2 hurricane with maximum sustained
winds near 100 mph. Georges was a large hurricane with the tropical
storm force winds, > 39 mph, extending out to 175 miles from the
center. The northeast and southeast quadrants of Georges were the
strongest, as evidenced by most of the damage in the Keys occurring
with easterly, southeasterly, and southerly winds.
The greatest storm surge flooding occurred on
the south coasts of the Keys with the most destructive storm surge
flooding damage being located between Cudjoe and Big Pine Keys.
The storm surge was estimated to be up to 6 feet in these areas.
The picture to the left was taken on South Roosevelt Boulevard in
Key West near the houseboat row area. Almost all of the houseboats
in this area were destroyed.

The lowest pressure measured during the hurricane,
974.4 mb, occurred at the Dry Tortugas C-MAN station when the eye
passed over around 6 PM 9/25/98.
The northern part of the eye passed over Key
West between noon and 1:30 PM 9/25/98. However, the pressure data
was unavailable due to power failure.
