ABOUT THE PRODUCTS AVAILABLE THROUGH THE NATIONAL WEATHER SERVICE OFFICE AT KEY WEST An on-line adaptation of Tony Cristaldi's "Products and Services for East Central Florida", customized and tweaked for Key West by Chip Kasper
 

The National Weather Service Weather Forecast Office (WFO) in Key West, Florida maintains a constant vigil for life threatening weather such as severe thunderstorms, tornadoes, hurricanes and coastal/freshwater flooding. The primary mission of the National Weather Service is to issue warnings and statements for these types of phenomena in order to minimize loss of life and property damage. The National Weather Service (NWS) also issues public forecasts that influence the daily decisions of thousands of residents across the Florida Keys, including the sizeable marine community. Commercial enterprises and public utilities, water resource managers, pilots, recreational boaters, commercial anglers, dive boat operators, campers and others in the recreational community rely on NWS forecasts.

A complete modernization, which has been underway within the National Weather Service promises to greatly improve the forecast and warning capabilities of  WFO Key West. Included in this modernization was the construction a new facility at the Key West International Airport in 1999. Automated weather observing systems, doppler radar, new and improved weather satellites, and advances in weather information processing systems will lead to improved timeliness and detail of forecasts and warnings.

Temperature and precipitation information available for the Key West dates back to November 1870!

Requests for detailed climate information or for hard copies should be directed to either the Southeast Regional Climate Center (SERCC) or the National Climatic Data Center (NCDC).

How the information Gets Out

COUNTY WARNING AREA (CWA) AND WARNING PROGRAM


The Key West WFO is responsible for issuing weather forecasts, watches, warnings, advisories and statements for people in the following counties in east central Florida:

Monroe

WFO Key West is also responsible for issuing the same suite of products within the marine service area which includes the coastal waters of the Florida Keys out to 60 nautical miles, including Florida Bay and the waters between Key West and Dry Tortugas.

Catalog of NWS Products
 

Some confusion still exists among the general public regarding the difference between a weather WATCH, WARNING and an ADVISORY.
 

  • A WATCH is issued to alert the public that CONDITIONS ARE FAVORABLE for severe or hazardous weather to develop.
     
  • A WARNING is issued to notify people that severe weather is IMMINENT or ALREADY OCCURRING.
     
  • An ADVISORY is issued to alert the public to hazardous weather conditions that aren't quite as severe as those for which warnings are issued.
As of May 19th, 1999, all watches and warnings for the Florida Keys and adjacent waters are issued by WFO Key West, with a few exceptions: Hurricane and Tropical Storm Watches (and Warnings) are issued by the Tropical Prediction Center, (TPC, formerly the National Hurricane Center, or NHC) while Severe Thunderstorm/Tornado Watches are issued by the Storm Prediction Center (SPC, formerly the National Severe Storms Forecast Center, Or NSSFC) in Norman, Oklahoma.

TROPICAL CYCLONE WATCHES/WARNINGS are coordinated through local NWS offices, but are issued by the TROPICAL PREDICTION CENTER in Miami. They are issued for coastal locations, and like special marine warnings, are referenced with respect to "break points" along the coast. There are two types of tropical cyclone watches warnings:

  • HURRICANE WARNING - Sustained winds of at least 74 mph (64 knots) associated with a hurricane are expected across coastal areas within 24 hours. Also, dangerously high tides and storm surges will accompany the high winds. If a tropical storm is expected to reach hurricane strength prior to landfall, then a hurricane watch/warning will be issued rather than a tropical storm watch/warning.
     
  • TROPICAL STORM WARNING - Sustained winds of 39 to 73 miles per hour (34 to 63 knots) associated with a tropical storm are expected across a specified coastal area within 24 hours or less. As mentioned before, dangerously high tides and storm surges along the coast usually accompany the high winds.
A TROPICAL STORM or HURRICANE WATCH indicates the possibility of tropical storm or hurricane conditions affecting coastal locations within 36 hours.

MARINE WARNING/ADVISORIES handled by WFO Key West:

  • GALE WARNING - Issued to alert the marine community that sustained winds of 39 to 54 miles per hour (34 to 47 knots) not directly associated with a tropical cyclone will occur over the marine area.
     
  • STORM WARNING - Issued to alert the marine community that sustained winds of at least 55 miles per hour (48 knots) not directly associated with a tropical cyclone will occur over the marine area.
  • SMALL CRAFT ADVISORY - An advisory in the coastal waters for winds from 20 to 38 miles per hour (18 to 33 knots) and/or for sea conditions that are considered potentially hazardous to small craft (there is no legal definition for "small craft").

SEVERE WEATHER WARNINGS alert the public to the presence of thunderstorms or tornadoes which produce damaging winds or hail, an are usually issued for one or two counties at a time, typically for up to an hour.

FLOOD WARNINGS/ADVISORIES are issued to alert the public to the potential threat to life and property due to heavy rainfall from thunderstorms, tropical cyclones, etc.

STATEMENTS are issued to inform the public of any weather watches and/or warnings that are currently in effect inside the county warning area. They are also issued to alert the public to non-severe but potentially hazardous weather situations (e. g. thunderstorm threats, dense fog, minor flooding). They are usually updated every 1 to 3 hours, except for the Hazardous Weather Outlook/Special Weather Statement.

ZONE, STATE AND COASTAL MARINE FORECASTS are the main products by which general weather forecasts reach the public, primarily via the news media. The Coastal Marine Forecast is used by the large marine community in east central Florida.


HOW THE INFORMATION GETS OUT

WFO Key West disseminates weather forecasts, warnings and other information directly to the residents of the Florida Keys directly, via the media (newspapers, television and radio stations, etc.), and by way of emergency management officials. This is accomplished through three primary dissemination systems: NOAA Weather Radio (NWR), NOAA Weather Wire Service (NWWS), and the NOAA Family of Services (FOS).

NOAA WEATHER RADIO (NWR)
Listening area forecasts and warning information is broadcast 24 hours a day, 365 days a year from WFO Key West. We transmit this information through the following NWR transmitters: WXJ-95 (162.400 MHz) and WWG60 (162.450 MHz).

The local "NWR listening area" comprised of the area covered by both transmitters includes all of the Florida Keys plus parts of the adjacent coastal waters.  However, weather conditions may temporarily alter the transmission range of broadcasts.

As previously stated, the primary goal of the NWS is to protect life and property. To accomplish this during severe weather, the NWR programming is adjusted, allowing the main emphasis of the broadcast to focus on the warning program. Due to their urgency, warnings are aired with the highest priority. This allows for maximum speed and efficiency in disseminating hazardous weather information and will pre-empt regularly scheduled programming.

WFO Key West broadcasts severe weather watches, warnings and advisories, detailing weather events such as hurricanes, tornadoes, thunderstorms, floods, and high winds. In addition, background information concerning the storm and appropriate safety tips are included with the warning. Statements keep listeners informed and updated on the storm's progress, and the status of watches, warnings or advisories that are in effect.

When dangerous conditions threaten the radio listening areas,  tones are broadcast which will allow specially built receivers to automatically display the nature of the threat and/or automatically activate.
Radios equipped for "SAME" activation will display the specific threat and allow for user-selection of counties, while the older "tone-alert" radios will usually sound a warning tone and activate on receipt of the correct signal.  The alarm tones are followed immediately by a message describing the threat, and updates are made as frequently as possible.  Check our Southern Region NOAA Weather Radio page for a description of which radios alert which counties.

The NWR warning alarm is tested each Wednesday between 11 AM and noon unless there is the threat of severe weather.

More info about dissemination of NWS products can be found at: http://www.nws.noaa.gov/wordout.shtml

EACH YEAR THOUSANDS OF PEOPLE CROWD THE ADJACENT COASTAL WATERS
OFF THE FLORIDA KEYS FOR SPORT LOBSTER SEASON. MANY MAY NOT BE AWARE
OF POTENTIAL MARINE WEATHER HAZARDS THAT MAY DEVELOP QUICKLY DURING
THE SUMMER HERE IN THE FLORIDA KEYS. THE NATIONAL WEATHER SERVICE IN
KEY WEST WOULD LIKE TO TAKE THIS OPPORTUNITY TO REVIEW SOME OF THESE
MARINE WEATHER HAZARDS.

* THUNDERSTORMS...DEVELOPMENT OF SCATTERED DAILY SHOWERS AND
THUNDERSTORMS IS A FACT OF LIFE DURING THE SUMMER IN THE STATE OF
FLORIDA. THUNDERSTORMS MAY ERUPT VERY QUICKLY AND MAY CATCH THE
UNSUSPECTING MARINER UNAWARE. THUNDERSTORMS OVER THE WATERS OFF
THE FLORIDA KEYS ARE USUALLY BRIEF...HOWEVER...THEY MAY PRODUCE VERY
HEAVY RAIN REDUCING VISIBILITIES...STRONG AND GUSTY WINDS WITH
LOCALLY ROUGH SEAS...AND DANGEROUS CLOUD TO SURFACE LIGHTNING STRIKES.

* WATERSPOUTS...THE AREA INCLUDING THE FLORIDA KEYS AND ADJACENT
COASTAL WATERS IS CONSIDERED THE WATERSPOUT CAPITAL OF THE WORLD.
WATERSPOUTS CAN BE JUST AS DANGEROUS AND DEADLY AS TORNADOES...AND
CAN EASILY CAPSIZE A SMALL WATERCRAFT. WATERSPOUTS USUALLY FORM AT
DARK...FLAT CLOUD BASES AND CAN LAST SEVERAL MINUTES.

* LIGHTNING...WHENEVER YOU CAN HEAR THUNDER...IT IS POSSIBLE FOR
LIGHTNING TO STRIKE NEARBY. IF CAUGHT IN THIS SITUATION...AVOID
BEING THE TALLEST OBJECT AROUND. ALSO STAY AWAY FROM ALL METAL
OBJECTS.

IF YOU KNOW THAT ONE OF THESE MARINE WEATHER HAZARDS IS EXPECTED IN
THE AREA THAT YOU ARE GOING...THE BEST COURSE OF ACTION WOULD BE TO
STAY IN PORT UNTIL THE BAD WEATHER PASSES. IF...HOWEVER...YOU ARE
CAUGHT OVER THE OPEN WATER...STAY BELOW DECK...AND REMEMBER TO
WEAR YOUR PERSONAL FLOTATION DEVICE. STAY TUNED TO NOAA WEATHER RADIO

FLOOD WATCH

PRODUCT HEADER: MIAFFAEYW

ISSUING OFFICE: WFO Key West

WHY ISSUED: Flooding of poorly drained low lying areas from prolonged heavy rainfall will be possible.  Since there are no natural rivers or lakes in the Florida Keys, the issuance of a FLOOD WATCH would be rare, however, during the landfall of a tropical cyclone in which extremely heavy rainfall would be likely, a FLOOD WATCH may be necessary.

ISSUED FOR: All or part of the Florida Keys.

TIMES ISSUED: As warranted, usually for a period of 12 to 24 hours or longer.

IN PERIODS OF MODERATE TO HEAVY RAINFALL OVER THE WATCH AREA THIS
AFTERNOON AND TONIGHT. SINCE THERE IS ALREADY STANDING WATER IN PLACES
...NEARLY SATURATED GROUND...AND CANALS AND SMALL STREAMS NEAR BANK
FULL FROM PREVIOUS RAINS...ADDITIONAL RAINFALL MAY PRODUCE SOME FLOODING

...COASTAL FLOOD WATCH SAINT AUGUSTINE TO FLAMINGO SUNDAY...
...HEAVY SURF ADVISORY CONTINUING SUNDAY NORTH OF JUPITER INLET...

WINDS ARE EXPECTED TO BE STRONGER TODAY AND FROM A MORE EASTERLY
DIRECTION. THIS WILL CAUSE FLOODING OF LOW LYING AREAS...AND SIGNIFICANT
BEACH EROSION ALONG EXPOSED COASTS FACING EAST AND NORTHEAST.

ALONG THE ATLANTIC COAST...LOSS OF SAND THAT OCCURRED THROUGH LAST
NIGHT WILL ALLOW HEAVY SURF TO MORE EASILY OVERFLOW BEACH AREAS AND
ROADS DURING THE LATE MORNING AND AFTERNOON AND AGAIN AROUND MIDNIGHT.
NORTH OF SAINT AUGUSTINE THE THREAT OF COASTAL FLOODING IS NOT AS
GREAT BUT STILL POSSIBLE TODAY AND TONIGHT.

ON SUNDAY COASTAL FLOOD WATCHES WILL REMAIN IN EFFECT FOR THE ENTIRE
FLORIDA EAST COAST. THOUGH WINDS WILL HAVE DIMINISHED SOME...EROSION CAUSED
YESTERDAY AND TODAY...MAY MAKE SOME AREAS MORE VULNERABLE. ALSO HEAVY

HURRICANE BERTHA DISCUSSION NUMBER  29
NATIONAL WEATHER SERVICE MIAMI FL
5 AM EDT THU JUL 11 1996

RECON OBSERVATIONS INDICATED THAT THE EYEWALL HAD DETERIORATED BUT
THEN REAPPEARED A FEW HOURS LATER.  CENTRAL PRESSURE WAS HOLDING
NEAR 972 MB AND THE PLANE REPORTED SOME VERY WARM TEMPS...18 TO 19
DEG C AT 700 MB...IN THE CENTER.  BERTHA HAS VERY INTENSE CONVECTION
NEAR THE CENTER AND SOME BANDING FEATURES...BUT NO EYE IS SEEN IN
THE IR SATELLITE IMAGERY.  UPPER-LEVEL OUTFLOW IS STRONG EXCEPT OVER
THE NORTHWEST QUADRANT...WHERE IT IS PROBABLY BEING INHIBITED BY THE
BACK SIDE OF A MID-LATITUDE TROUGH WHICH IS PROPAGATING EASTWARD.
CURRENT INTENSITY ESTIMATE IS 85 KNOTS BUT THIS MAY BE INFLATED A
BIT...CONSIDERING THE LATEST FLIGHT-LEVEL WIND DATA.  LITTLE
SIGNIFICANT CHANGE IN STRENGTH IS FORECAST.  HOWEVER...AFTER THE
TROUGH PASSES THERE IS A POSSIBILITY THAT BERTHA COULD INTENSIFY A
LITTLE SINCE THE HURRICANE IS OVER WARM WATER AND COULD PASS OVER
EVEN WARMER WATERS...I.E. THE GULF STREAM.

THE FORWARD SPEED HAS SLOWED SOME MORE...TO 330/11.  AT 500 MB...THE
MID-LATITUDE TROUGH THAT HAS DRAWN BERTHA MORE NORTHWARD IS NOW
APPROXIMATELY IN PHASE WITH THE TROPICAL CYCLONE.  THIS TROUGH WILL
MOVE ON...AND PRESUMABLY LEAVE BERTHA BEHIND.  THE NEXT UPSTREAM
TROUGH LOOKS MUCH WEAKER IN THE EMC GLOBAL MODEL PREDICTIONS...AND
IT APPEARS THAT BERTHA WILL NEED TO REACH THE LATITUDE OF THE
CAROLINAS BEFORE IT CAN BE SIGNIFICANTLY IMPACTED BY THIS TROUGH.
THERE IS A STRONG DEEP-LAYER ANTICYCLONE TO THE EAST-NORTHEAST OF
BERTHA.  THE LATTER FEATURE SHOULD PROVIDE A NORTHWARD STEERING
COMPONENT TO KEEP THE HURRICANE MOVING ALONG AT AROUND 10-11 KNOTS.
UNFORTUNATELY...IT APPEARS THAT THIS ANTICYCLONE WILL PREVENT THE
TROPICAL CYCLONE FROM TURNING SIGNIFICANTLY EASTWARD BEFORE IT
REACHES THE COASTLINE.  THERE IS STILL A POSSIBILITY THAT BERTHA
COULD RECURVE EASTWARD AND MISS THE COAST ENTIRELY AS SHOWN BY THE
BAROTROPIC GUIDANCE.  HOWEVER ALL OF OUR PRIMITIVE EQUATION
GUIDANCE... INCLUDING THE GFDL MODEL...BRING THE HURRICANE
OVER LAND WITHIN 36 HOURS...AND SO DOES OUR OFFICIAL FORECAST.

THE LANDFALL TIMING IS CRITICALLY DEPENDENT ON THE HEADING OF BERTHA
WHEN IT APPROACHES THE COAST.  OUR PRESENT THINKING IS THAT THE
CENTER WILL BE NEAR THE COAST ON FRIDAY.  ONE SHOULD BEAR IN MIND
THAT THIS IS A LARGE HURRICANE.  TROPICAL STORM FORCE WINDS COULD BE
NEAR THE COAST IN THE WARNING AREA MUCH EARLIER...BY THIS EVENING.

...AREAS AFFECTED...
THIS STATEMENT APPLIES TO PEOPLE IN ALL PARTS OF THE KEYS OF MONROE
COUNTY FLORIDA CONCERNING THE EFFECTS OF HURRICANE FLOYD.

...WATCHES...WARNINGS AND ADVISORIES...
A TROPICAL STORM WARNING IS IN EFFECT FOR THE UPPER AND MIDDLE
FLORIDA KEYS AND THE ADJACENT COASTAL WATERS...FROM THE SEVEN-MILE

SUSPEND FLIGHT OPERATIONS DURING TODAY.

...STORM SURGE FLOODING/TIDES/OTHER MARINE HAZARDS...
SOME MINOR TIDAL OVERFLOW WILL OCCUR ALONG THE UPPER AND MIDDLE
KEYS...NEAR THE TIMES OF HIGH TIDE TODAY THROUGH WEDNESDAY.
ALREADY...SOME SPOTS OF U.S. 1 NORTH OF KEY LARGO HAD WATER VERY
CLOSE TO THE ROAD AND AS THE HURRICANE MOVES CLOSER TO LAND
ADDITIONAL FLOODING PROBLEMS ARE EXPECTED. THERE COULD BE AN
ADDITIONAL PROBLEM OF WATER PILING UP IN FLORIDA BAY LATE TONIGHT
AND WEDNESDAY AS WINDS SHIFT TO MORE WESTERLY.

TIMES OF THE HIGH TIDES ARE THESE...
OCEAN REEF HARBOR...NORTH END OF KEY LARGO
 1217 PM TUE  1225 AM WED  101 PM WED

KEY LARGO...LARGO SOUTH SOUND

MARINERS SHOULD REMAIN IN PORT TODAY OF THE UPPER AND MIDDLE KEYS
WATERS...WITH A TROPICAL STORM WARNING IN EFFECT. SMALL CRAFT
ADVISORIES WILL REMAIN IN EFFECT FOR THE LOWER KEYS. WIND WAVES
TODAY INTO TONIGHT WILL REACH AS HIGH 8 TO 12 FEET OVER OPEN WATERS
THE KEYS. ALSO...LARGE SWELLS GENERATED ON THE WEST SIDE OF FLOYD
WILL PROPAGATE SOUTHWARD DOWN THE STRAITS OF FLORIDA AFFECTING
FLORIDA STRAITS WATERS OF THE UPPER AND MIDDLE KEYS TODAY AND
TONIGHT. MARINERS IN THE LOWER KEYS SHOULD MONITOR LATER WEATHER
ISSUANCES...AND BE ALERT TO POSSIBLY DETERIORATING WEATHER...WIND
AND SEAS.

...WIND IMPACTS...
FLOYD CONTINUES TO BE VERY LARGE IN SIZE. TROPICAL STORM FORCE WINDS
EXTEND OUT 150 MILES TO THE SOUTHWEST OF FLOYDS CENTER...AND 190
MILES TO THE NORTHWEST. ACCORDING TO EMERGENCY MANAGEMENT...SOME OF
THESE WINDS HAVE ALREADY BEEN IMPACTING THE OCEAN REEF AREA OF UPPER
KEY LARGO AND FOWEY ROCKS LIGHT OFF MIAMI HAS BEEN REPORTING WIND
GUSTS PAST 40 MPH MOST OF THE EARLY MORNING HOURS.

WIND ACROSS THE WATERS OF THE FLORIDA KEYS EARLY THIS MORNING HAVE
BEEN 25 TO 30 MPH SUSTAINED...WITH GUSTS AT TIMES NEAR 35 MPH. WIND
DIRECTION HAS BEEN MOSTLY FROM THE NORTH...EXCEPT NORTH TO NORTHEAST
AT DRY TORTUGAS.

WIND AT THE AIRPORTS FROM MARATHON TO KEY WEST HAVE BEEN NORTH AS
HIGH AS NEAR 20 MPH...WITH GUSTS AS HIGH AS 25 TO 30 MPH.

BASED ON THE CURRENT FORECAST TRACK...SUSTAINED WINDS OF TROPICAL
STORM FORCE WILL SPREAD SLOWLY DOWN THE KEYS TODAY. DURING THIS
MORNING MOST OF THE TROPICAL STORM FORCE WINDS OF 39 MPH OR GREATER
WILL OCCUR IN THE UPPER KEYS AND SURROUNDING WATERS...POSSIBLY
REACHING THE MIDDLE KEYS AND THE ADJACENT WATERS THIS AFTERNOON AS
FLOYD MAKES IT CLOSEST PASS TO THE KEYS. WIND GUSTS MAY EVEN EXCEED
50 MPH THIS AFTERNOON AND EVENING FROM KEY LARGO TO OCEAN REEF IF
FLOYD TRACKS CLOSER TO THE AREA.

WINDS ACROSS THE LOWER KEYS AND THE ADJACENT WATERS WILL ONLY BE
SLIGHTLY LOWER DURING TODAY AND TONIGHT...BUT OCCASIONAL WIND GUSTS
PAST 40 MPH ARE POSSIBLE. SUSTAINED WINDS OF 25 MPH OR GREATER WILL
OCCUR OVER THE LOWER KEYS TODAY PROMPTING A WIND ADVISORY. DRIVE
WITH EXTREME CARE TODAY...ESPECIALLY ON THE BRIDGES AS THE WIND WILL
BE PERPENDICULAR TO U.S. 1

WIND DIRECTION ACROSS THE KEYS AND ADJACENT MARINE AREA WILL BE
MAINLY NORTH THIS MORNING...SHIFTING TO NORTHWEST THIS AFTERNOON AND
THEN TO WEST OR WEST-NORTHWEST TONIGHT.

ALSO...WIND COULD BE EVEN STRONGER IF ANY OUTER RAINBANDS FROM FLOYD
MAKE IT INTO THE KEYS.

...RAINFALL INFORMATION...
ALTHOUGH THERE CAN BE OCCASIONAL DOWNPOURS OF RAIN IN ANY RAINBAND
THAT DOES MOVE THROUGH THE KEYS...NO WIDESPREAD HEAVY RAINS WILL
OCCUR DUE TO THE FAST MOVEMENT AND THE LOCATION OF FLOYD IN RELATION
TO THE KEYS. IF FLOYD TURNS MORE SHARPLY TO THE NORTHWEST THERE IS
EVEN A POSSIBILITY THAT MUCH OF THE RAINBANDS STAY NORTH AND EAST OF
THE AREA.

AS OF EARLY THIS MORNING THE CLOSEST RAINBAND TO THE KEYS WAS NOT
QUITE TO ANDROS ISLAND. KEY WEST AND MIAMI RADARS AT 6 AM WERE
ALMOST FREE OF DETECTING ANY PRECIPITATION ASSOCIATED WITH FLOYD.

CONTINUE TO DIMINISH THIS EVENING AND TONIGHT.  RESIDENTS SHOULD ACT
QUICKLY IF A TORNADO IS OBSERVED...OR IF THE NATIONAL WEATHER
