... Hurricane force wind gusts moving into coastal waters of Palm Beach
County...
... Areas affected...
this statement applies to Palm Beach... Broward... Miami-Dade... Glades...
Hendry... Collier... and Mainland Monroe counties of South Florida.
... Watches and warnings...
a Tornado Watch is in effect for Glades, Hendry, and Palm Beach
counties including Lake Okeechobee and the adjacent coastal waters...
... Hurricane Warning is in effect for the Palm Beach, Broward and
Miami-Dade Metro areas and Lake Okeechobee...
An inland hurricane wind warning is in effect for
Glades... Hendry... western Palm Beach... and western Broward counties.
A Tropical Storm Warning is in effect for coastal Collier and
Mainland Monroe counties.
An inland Tropical Storm Wind Warning is in effect for inland
Collier and western Miami-Dade counties.
A Flood Watch is in effect for all of South Florida until 8 PM
Sunday night.
... Storm information...
at 5 PM EDT... the center of dangerous Hurricane Jeanne was located
near latitude 27.1 north... longitude 78.8 west. This location is
about 90 miles east northeast of West Palm Beach. Jeanne has been
moving between west and west northwest near 14 mph. Maximum
sustained winds are 115 miles an hour with higher gusts... .making
Jeanne a dangerous category 3 major hurricane.
... Precautionary/preparedness actions...
persons should remain in protected buildings until hurricane
conditions subside on Sunday morning.
... Storm surge flood and storm tide impacts...
the current forecast track of Hurricane Jeanne would result in
landfall just north of Palm Beach County around midnight tonight.
High tide along the Atlantic coast of South Florida will be around 6
PM which means the water level will reach high tide and then
continue to rise to a maximum through 9 or 10 PM before finally
beginning to recede slowly. This would result in a maximum storm
tide around 3.5 feet above mean sea level in the extreme northeast
part of Palm Beach County including Jupiter Inlet. Minor flooding of
beach roads and Waterfront neighborhoods around Jupiter Inlet
Colony... Tequesta... and Juno Beach might occur. For Broward and
Miami-Dade counties... storm tides of 1 or 2 feet above mean sea
level are possible.
For Lake Okeechobee... the water level was near 16 feet at 2 PM. As
winds increase and shift from northwest to west to southwest... water
levels inside the dike will rise from 3 feet along the southeast
shore around 10 PM to 3.5 feet along the Eastern Shore around
midnight to near 4 feet along the North Shore around 3 am. All areas
outside protection of the Hoover Dike... including
Ritta... Torry... and Kreamer islands as well as marinas and docks in
the Belle Glade and Pahokee areas... can be expected to flood. The
Hoover Dike protects inhabited areas to more than 30 feet.
For the southwest Gulf Coast... onshore tropical storm force winds
will cause storm tides up to 2 feet from Cape Sable to Marco Island
around 3 am and about one foot north of Marco Island to Bonita Beach
around 4 am. This could cause some minor flooding of low lying roads
between Marco Island and Chokoloskee and Everglades City.
... Wind impacts...
at 5 PM... wind gusts in Palm Beach County included 43 mph at West
Palm Beach and 38 mph at Lake Worth. In Broward winds were gusting
to 40 mph at Pompano Beach and Fort Lauderdale and 35 mph at
Pembroke Pines. In Miami-Dade County wind gusts were 26 mph at
Miami... 28 mph at Miami Beach and 31 mph at Kendall with a wind gust
of 47 mph at Fowey Rocks light south of Key Biscayne.
A South Florida water management district observation reported a wind
gust of 44 mph in the northern portion of Lake Okeechobee.
Miami Doppler radar shows squalls over the Atlantic coastal waters
with peak wind gusts estimated around 75 mph. Over land... radar
estimates squalls with wind gusts of 50 to 60 mph are affecting most
of Palm Beach County. Radar estimated wind gusts of 35 to 45 mph
occurring over Broward County and 25 to 35 mph wind gusts over
Miami-Dade County.
Sustained hurricane force winds... in excess of 73 mph... will likely
begin over portions of Metro Palm Beach County this evening and last
until after midnight. Gusts in excess of 100 mph are possible.
Winds over Metro Palm Beach will begin to decrease late tonight and
are forecast to be below tropical storm force by noon Sunday.
Over southern Metro Broward and all of Miami-Dade... wind gusts of 35
mph will continue through the evening with winds reaching sustained
tropical storm force late this evening and continuing through the
night.
Over inland areas of Palm Beach... Broward... Glades... and Hendry
counties ... winds will become sustained at tropical storm force... 39
miles per hour... beginning this evening and lasting through Sunday
morning. Frequent gusts to hurricane force will occur over inland
areas... especially Lake Okeechobee and western Palm Beach
County... from midnight tonight through early Sunday morning.
Sustained hurricane force winds are possible over Lake
Okeechobee... especially if the center of Jeanne moves farther south.
The winds will decrease by Sunday afternoon.
Over the southwest Gulf Coast region... including Big Cypress
Swamp... Everglades National Park and the Naples... Marco Island
area... frequent winds gusts in excess of 39 mph... tropical storm
strength... will begin this evening and last through noon Sunday.
... Local marine impacts...
hurricane force winds are affecting Palm Beach and northern Broward
County coastal waters with tropical storm force winds from the
southern Broward to the Miami-Dade Atlantic coastal waters as well
as in the Gulf of Mexico coastal waters of Collier and Mainland
Monroe counties.
... Local flood impacts...
Doppler weather radar estimates rainfall amounts of 4 to 6 inches
have fallen over portions of the northwest Bahamas today. Similar amounts
of rain will likely spread across portions of South Florida tonight
with an additional 2 to 4 inches on Sunday. This will mean maximum
storm totals of 6 to 10 inches across South Florida with a few spots
nearing one foot of rain. If a feeder band sets up across South
Florida... heavy rainfall may continue Sunday night and Monday.
This rain will cause extensive freshwater flooding and a Flood Watch
is in effect.
... Local tornado impacts...
there will be a slight threat of tornadoes in the rainbands of
Jeanne this evening.
... Next update...
the next regularly scheduled Hurricane Jeanne local statement will
be issued around 8 PM today.

Statement as of 6:00 PM EDT on September 25, 2004
... The Flood Watch remains in effect for the areas of...
Hendry... Glades... Palm Beach... Collier... Broward... Mainland Monroe
and Miami-Dade until 600 PM EDT Sunday evening...
Rain bands will continue to move onshore over South Florida ahead of
Hurricane Jeanne. Rainfall amounts through Monday across Palm
Beach... Broward... Glades... and Hendry counties are expected to be
from 6 to 8 inches with local amounts as high as 12 inches near
where the center of Hurricane Jeanne passes. This rain will cause
extensive freshwater flooding. Elsewhere across South
Florida... rainfall amounts from 3 to 6 inches can occur with Jeanne
which can produce flooding in low lying and poorly drain areas.
A Flood Watch means the threat of flooding exists within the watch
area. Persons in and near the affected areas should monitor NOAA
Weather Radio and local television and radio. Be ready to take quick
action if flooding is observed or a Flood Warning is issued.
