...TODAY IN METRO DENVER WEATHER HISTORY...

23-24 IN 1887...THE FIRST MEASURABLE SNOWFALL OF THE SEASON TOTALED
        3.1 INCHES.  NORTH WINDS TO 20 MPH WERE RECORDED ON THE
        23RD.  THIS WAS THE ONLY MEASURABLE SNOW OF THE MONTH.
      IN 1932...POST-FRONTAL SNOWFALL FROM THE LATE EVENING OF THE
        23RD CONTINUED THROUGH THE LATE AFTERNOON OF THE 24TH AND
        TOTALED 6.2 INCHES.  SOUTHEAST WINDS WERE SUSTAINED TO 25
        MPH WITH GUSTS TO 26 MPH ON THE 23RD.  TEMPERATURES COOLED
        FROM A HIGH OF 68 DEGREES ON THE 23RD TO A LOW OF 25
        DEGREES ON THE 24TH...THE COLDEST READING OF THE MONTH THAT
        YEAR.  MANY TREES THAT HAD NOT SHED THEIR LEAVES BECAME
        HEAVILY LADEN BY THE WET SNOW.  MANY BRANCHES WERE BROKEN...
        AND A FEW TREES TOPPLED UNDER THE WEIGHT OF THE SNOW.  THE
        LANDSCAPE BECAME ONE OF RARE BEAUTY.
24    IN 1956...SOUTHWEST WINDS GUSTED TO 56 MPH AND PRODUCED SOME
        BLOWING DUST AT STAPLETON AIRPORT.  A COLD FRONT PRODUCED
        A THUNDERSTORM WITH 1/8 INCH HAIL.  RAIN LATER CHANGED TO
        SNOW.  PRECIPITATION TOTALED ONLY 0.11 INCH AND SNOWFALL
        ONLY 0.3 INCH.
      IN 1973...STRONG WINDS RAKED THE EASTERN FOOTHILLS...CAUSING
        DAMAGE IN BOULDER AND JEFFERSON COUNTIES.  THE HEAVIEST
        DAMAGE OCCURRED IN THE BOULDER AREA WHERE 20 TO 25 MOBILE
        HOMES WERE HIT...SOME POWER AND TELEPHONE LINES WERE BLOWN
        DOWN...AND A STORE WAS DAMAGED.  A WIND GUST TO 76 MPH WAS
        RECORDED IN BOULDER AT THE NATIONAL BUREAU OF STANDARDS.
        NORTHWEST WINDS GUSTED TO 46 MPH AT STAPLETON INTERNATIONAL
        AIRPORT.
24-25 IN 1921...RAINFALL TOTALED 0.35 INCH OVERNIGHT BEHIND AN
        APPARENT COLD FRONT.  NORTH WINDS WERE SUSTAINED TO 40 MPH
        WITH GUSTS TO 46 MPH ON THE 25TH.  TEMPERATURES PLUNGED
        FROM A HIGH OF 73 DEGREES ON THE 24TH TO A LOW OF 39
        DEGREES ON THE 25TH.
      IN 1923...RAIN OVERNIGHT CHANGED TO SNOW DURING THE MORNING.
        THE HEAVY SNOWFALL ACCUMULATED TO 12.0 INCHES BEFORE ENDING
        ON THE MORNING OF THE 25TH.  POST-FRONTAL NORTH WINDS WERE
        SUSTAINED TO 22 MPH WITH GUSTS TO 23 MPH ON THE 24TH.
      IN 1997...ONE OF THE WORST AND DEADLIEST BLIZZARDS OF THE
        DECADE DEVELOPED OVER EASTERN COLORADO AS DEEP EAST TO
        NORTHEAST FLOW ASSOCIATED WITH A VIGOROUS UPPER LEVEL LOW
        PRESSURE SYSTEM OVER THE FOUR CORNERS...COMBINED WITH A
        STRONG ARCTIC AIR MASS OVER THE CENTRAL GREAT PLAINS.
        SNOWFALL TOTALS ACROSS METRO DENVER RANGED FROM 14 TO 31
        INCHES.  THE HEAVIEST SNOWFALL OCCURRED IN THE FOOTHILLS
        WEST AND SOUTHWEST OF DENVER WHERE 2 TO 4 FEET OF SNOW
        WERE MEASURED.  SUSTAINED WINDS TO 40 MPH WITH GUSTS AS
        HIGH AS 60 MPH PRODUCED ZERO VISIBILITIES AND EXTREMELY
        COLD WIND CHILL TEMPERATURES FROM 25 BELOW TO 40 BELOW
        ZERO.  WINDS WHIPPED THE SNOW INTO DRIFTS 4 TO 10 FEET
        DEEP.  SEVERAL MAJOR AND INTERSTATE HIGHWAYS WERE CLOSED
        AS TRAVEL BECAME IMPOSSIBLE.  RED CROSS SHELTERS WERE SET
        UP FOR HUNDREDS OF TRAVELERS WHO BECAME STRANDED WHEN
        THEY HAD TO ABANDON THEIR VEHICLES.  FOUR PEOPLE DIED IN
        NORTHEASTERN COLORADO AS A RESULT OF THE BLIZZARD.  NONE OF
        THE DEATHS WERE IN METRO DENVER.  AT DENVER INTERNATIONAL
        AIRPORT...4 THOUSAND TRAVELERS WERE STRANDED WHEN THE AIRPORT
        WAS FORCED TO SHUT DOWN.  AT LEAST 120 CARS WERE ABANDONED
        ALONG PENA BLVD....THE ONLY ARTERIAL LEADING INTO AND OUT
        OF DIA.  THE BLIZZARD COST AIR CARRIERS AT LEAST 20 MILLION
        DOLLARS.  THOUSANDS OF CATTLE DIED IN THE STORM OVER
        NORTHEASTERN COLORADO...RESULTING IN LOSSES TOTALING 1.5
        MILLION DOLLARS.  SOME OF THE MORE IMPRESSIVE SNOWFALL
        TOTALS INCLUDED:  51 INCHES AT COAL CREEK CANYON; 48
        INCHES AT SILVER SPRUCE RANCH...NEAR WARD; 42 INCHES AT
        INTERCANYON...IN THE FOOTHILLS SOUTHWEST OF DENVER; 37 INCHES
        AT SEDALIA; 35 INCHES AT ASPEN SPRINGS AND CONIFER IN THE
        FOOTHILLS WEST OF DENVER; 31 INCHES AT ELDORADO SPRINGS...
        SOUTHEAST AURORA...AND ENGLEWOOD; AND 30 INCHES ON TABLE MESA
        IN BOULDER.  SNOWFALL TOTALED 21.9 INCHES AT THE SITE OF
        THE FORMER STAPLETON INTERNATIONAL AIRPORT...SETTING A NEW
        24-HOUR SNOWFALL RECORD OF 19.1 INCHES FOR THE MONTH.
        SNOWFALL TOTALED ONLY 14 INCHES AT DENVER INTERNATIONAL
        AIRPORT WHERE NORTH WINDS GUSTED TO 39 MPH ON THE 24TH.
        HIGH TEMPERATURE OF ONLY 21 DEGREES ON THE 25TH EQUALED
        THE RECORD LOW MAXIMUM FOR THE DATE FIRST SET IN 1873.
        LOW TEMPERATURE OF ONLY 3 DEGREES ON THE 26TH SET A NEW
        RECORD MINIMUM FOR THE DATE.

...EXTREME WIND CHILL...POTENTIALLY LIFE-THREATENING AND OFTEN
OVERLOOKED...

THE COMBINATION OF WIND AND LOW TEMPERATURE IN WINTER CAN BE DEADLY.
THE WIND CHILL INDEX HELPS YOU DETERMINE WHEN DANGEROUS CONDITIONS
DEVELOP THAT COULD LEAD TO FROSTBITE OR HYPOTHERMIA.  IT TAKES INTO
ACCOUNT HEAT LOSS FROM THE HUMAN BODY TO ITS SURROUNDINGS DURING
COLD AND WINDY WEATHER.  THE CALCULATION UTILIZES WIND SPEED IN
MILES PER HOUR AND TEMPERATURE IN DEGREES FAHRENHEIT.  FOR
EXAMPLE...A TEMPERATURE OF MINUS 5 DEGREES OCCURRING WITH A 20 MPH
WIND GIVES A WIND CHILL NEAR MINUS 30 DEGREES.  THIS MEANS THAT YOUR
BODY WILL LOSE HEAT AT THE SAME RATE AS IT WOULD IF THE AIR
TEMPERATURE WERE MINUS 30 DEGREES WITH NO WIND.  WIND CHILL VALUES
NEAR MINUS 25 DEGREES MEAN THAT FROSTBITE IS POSSIBLE WITHIN 15
MINUTES.

FROSTBITE IS THE FREEZING OF SKIN AND THE BODY TISSUE JUST BENEATH
IT. IT FIRST AFFECTS EXPOSED BODY TISSUE WHERE BLOOD CIRCULATION MAY
BE LIMITED SUCH AS YOUR FINGERS... TOES...NOSE AND EARS.  TO
MINIMIZE FROSTBITE...MAKE SURE ALL BODY PARTS ARE WELL COVERED.
WHEN FROSTBITE STARTS...FEELING IS LOST IN THE AFFECTED AREA AND THE
FROZEN TISSUE WILL TAKE ON A WHITE OR PALE APPEARANCE.  IF YOU
SUSPECT YOU ARE EXPERIENCING FROSTBITE...HOLD THE FROSTBITTEN AREA
CLOSELY AGAINST WARM SKIN TO RETURN BLOOD FLOW AND WARMTH TO THE
AFFECTED AREA.

HYPOTHERMIA IS A DANGEROUSLY LOW BODY TEMPERATURE AND IS THE MOST
COMMON WINTER WEATHER KILLER. WHEN YOU HEAR OF A
HIKER...CLIMBER...HUNTER OR A STRANDED TRAVELER PERISHING FROM COLD
WEATHER EXPOSURE...HYPOTHERMIA WAS THE CAUSE.  MOST PEOPLE ARE
SURPRISED TO LEARN THAT HYPOTHERMIA DEATHS CAN OCCUR WITH
TEMPERATURES BETWEEN 30 AND 50 DEGREES.  IF YOU OR YOUR CLOTHING ARE
WET...THEN HYPOTHERMIA BECOMES EVEN MORE LIKELY.

WARNING SIGNS OF HYPOTHERMIA INCLUDE UNCONTROLLABLE
SHIVERING...MEMORY LOSS... DISORIENTATION...SLURRED SPEECH AND
DROWSINESS.  IMMEDIATE MEDICAL ATTENTION SHOULD BE GIVEN TO VICTIMS
SUSPECTED OF SUFFERING FROM HYPOTHERMIA.  IF NO HELP IS
AVAILABLE...THE VICTIM SHOULD BE WARMED SLOWLY WITH WARM LIQUIDS
ALONG WITH DRY CLOTHING AND BLANKETS.

THE NATIONAL WEATHER SERVICE WILL ISSUE WIND CHILL ADVISORIES AND
WARNINGS WHEN A DEADLY COMBINATION OF WIND AND COLD AIR THREATEN.
TO LEARN MORE ABOUT WIND CHILL...VISIT THE NATIONAL WEATHER SERVICE
INTERNET SITE USING LOWER CASE LETTERS: WEATHER.GOV/OM/WINDCHILL.

WHEN COLD WEATHER THREATENS...FOLLOW THESE TIPS FOR SURVIVAL...

STAY DRY...WET CLOTHING RESULTS IN MUCH FASTER HEAT LOSS FROM YOUR
BODY.  WEAR WATERPROOF INSULATED BOOTS.

STAY COVERED...WEAR MITTENS OR GLOVES AND WEAR A HAT. AT LEAST HALF
OF YOUR BODY HEAT IS LOST IF YOUR HEAD IS NOT COVERED.

DRESS LAYERED...TRAPPED AIR BETWEEN LOOSE FITTING CLOTHING HELPS TO
INSULATE.

STAY INFORMED...HAVE A PORTABLE NOAA WEATHER RADIO NEARBY TO KEEP
YOU UP-TO-DATE WITH THE LATEST FORECASTS AND WARNINGS.  USE WIND
CHILL TEMPERATURES TO GUIDE YOU IN DRESSING PROPERLY FOR THE
OUTDOORS.  ON VERY COLD DAYS...MINIMIZE YOUR EXPOSURE TO THE
OUTDOORS IF POSSIBLE.

        EQUALED THE RECORD HIGH FOR THE DATE.  HIGH TEMPERATURES
        OF 86 DEGREES ON THE 19TH...83 DEGREES ON THE 21ST...AND 84
        DEGREES ON THE 22ND WERE RECORD HIGHS FOR THE DATES.  LOW
        TEMPERATURE OF 49 DEGREES ON THE 23RD WAS A RECORD HIGH
        MINIMUM FOR THE DATE.  LOW TEMPERATURES DURING THE PERIOD
        WERE IN THE 40`S AND LOWER 50`S.
19-23 IN 1906...HEAVY SNOWFALL TOTALED 22.7 INCHES IN THE CITY OVER
        THE 5 DAYS.  RAIN CHANGED TO SNOW ON THE EVENING OF THE

        FROM 8:00 PM ON THE 20TH TO 8:00 PM ON THE 22ND.  THE MOST
        SNOW ON THE GROUND WAS 13.3 INCHES ON THE EVENING OF THE
        23RD.  THIS WAS THE FIRST SNOW OF THE SEASON AND THE ONLY
        SNOW OF THE MONTH.  WINDS DURING THE STORM WERE FROM THE
        NORTH AT SUSTAINED SPEEDS OF 20 TO 30 MPH EACH DAY.
        TEMPERATURES DURING THE STORM WERE GENERALLY IN THE 20`S.
22-23 IN 1914...POST-FRONTAL RAIN CHANGED TO SNOW.  PRECIPITATION

        BUT AN ESTIMATED 8.0 INCHES OF SNOW MELTED AS IT FELL.
        NORTH TO NORTHEAST WINDS WERE SUSTAINED TO 29 MPH WITH
        GUSTS TO 30 MPH ON BOTH DAYS.
      IN 1975...A VIGOROUS COLD FRONT MOVING ACROSS METRO DENVER
        FOLLOWED BY STRONG NORTHEAST WINDS GUSTING TO 52 MPH
        PRODUCED BILLOWS OF BLOWING DUST AND PLUNGED THE
        TEMPERATURE 21 DEGREES IN AN HOUR.  THE SURFACE
        VISIBILITY WAS REDUCED TO 1/4 MILE IN BLOWING DUST AT
        STAPLETON INTERNATIONAL AIRPORT.  THE TEMPERATURE COOLED
        FROM A DAILY RECORD HIGH OF 81 DEGREES TO A LOW OF 38
        DEGREES BY DAY`S END.  THE FIRST SNOWFALL OF THE SEASON
        TOTALED 2.7 INCHES ON THE 23RD.  THIS WAS THE ONLY

        RANGED FROM 4 TO 8 INCHES.  SEDALIA...SOUTH OF DENVER...
        RECEIVED 8 INCHES OF SNOW.  WINDS STRENGTHENED ON THE
        PLAINS AND PRODUCED BLIZZARD CONDITIONS...REDUCING SURFACE
        VISIBILITIES TO LESS THAN 1/4 MILE.  I-70 WAS CLOSED
        FROM JUST EAST OF DENVER AT GUN CLUB ROAD TO THE KANSAS

...WIDESPREAD HIGH WINDS VISIT COLORADO DURING THE WINTER...

GOVERNOR JOHN HICKENLOOPER HAS PROCLAIMED THIS WEEK THROUGH OCTOBER
25TH AS WINTER WEATHER AWARENESS WEEK IN COLORADO.

THE TWO MAIN CAUSES OF HIGH WINDS IN COLORADO DURING THE COLD SEASON
ARE THE AIR PRESSURE DIFFERENCE BETWEEN STRONG LOW PRESSURE AND COLD
HIGH PRESSURE SYSTEMS...AND CHINOOK WINDS DEVELOPING ACROSS THE
FRONT RANGE AND OTHER EASTERN MOUNTAIN RANGES.

A STRONG...COLD HIGH PRESSURE SYSTEM MOVING IN FROM THE NORTH AND
SETTING UP TO THE WEST OF THE ROCKIES CAN GENERATE A DAMAGING WIND
DOWN THE LEEWARD SLOPES OF THE MOUNTAINS...KNOWN AS A BORA. THESE
EPISODES FEATURE WIDESPREAD HIGH WINDS FROM THE WEST OR NORTHWEST
INTO THE ADJACENT PLAINS AT SPEEDS WHICH CAN EXCEED 100 MPH. MUCH
MORE RARE ARE THOSE EPISODES WHEN LOW PRESSURE IS ACROSS THE
ROCKIES...AND STRONG...COLD HIGH PRESSURE IS ACROSS THE GREAT
PLAINS.

THE RESULT IS DAMAGING WINDS FROM THE EAST ACROSS THE WESTERN SLOPES
OF MOUNTAIN RANGES AND ADJACENT VALLEYS.

MID AND UPPER LEVEL WINDS OVER COLORADO ARE MUCH STRONGER IN THE
WINTER THAN IN THE WARM SEASON...BECAUSE OF THE HUGE DIFFERENCE IN
TEMPERATURE FROM NORTH TO SOUTH ACROSS NORTH AMERICA.  WEST WINDS...
UNDER CERTAIN CONDITIONS...CAN BRING WARM...DRY CHINOOK WINDS
PLOWING DOWN THE SLOPES OF THE EASTERN MOUNTAINS. THESE WINDS CAN
EXCEED 100 MPH IN EXTREME CASES...BRINGING THE POTENTIAL FOR
WIDESPREAD DAMAGE.  WINDS OF 60 TO NEAR 100 MPH WILL OCCUR IN AND
NEAR THE FOOTHILLS IN AREAS SUCH AS FORT COLLINS...BOULDER...
DENVER...COLORADO SPRINGS...CANON CITY...WESTCLIFFE...WALSENBURG AND
TRINIDAD. THE AREAS AROUND BOULDER AND WESTCLIFFE ARE ESPECIALLY
PRONE TO THESE EXTREME WIND EPISODES.

DANGERS FROM HIGH WINDS INCLUDE FLYING DEBRIS...REDUCED VISIBILITY
DUE TO DUST...DAMAGED OR DESTROYED STRUCTURES...DOWNED POWER
LINES...AND OVERTURNED VEHICLES.  THE NATIONAL WEATHER SERVICE WILL
ISSUE A HIGH WIND WATCH WHEN THERE IS AROUND A 50 PERCENT CHANCE FOR
HIGH WINDS TO DEVELOP DURING THE NEXT DAY OR TWO. WHEN THE THREAT
BECOMES MORE CERTAIN IN A SPECIFIC AREA...A HIGH WIND WARNING WILL
BE ISSUED.  COLD STRONG WINDS CAN ALSO BRING DANGEROUSLY LOW WIND
CHILL VALUES...PROMPTING A WIND CHILL ADVISORY OR WIND CHILL WARNING.

IF HIGH WINDS ARE FORECAST FOR YOUR AREA...YOU SHOULD BRING
LIGHTWEIGHT OBJECTS INDOORS...OR TIE THEM DOWN OUTDOORS...OR MOVE
THEM SO THEY DO NOT BECOME DANGEROUS MISSILES.  ANY DOWNED POWER
LINES SHOULD NOT BE APPROACHED. INSTEAD CALL THE UTILITY COMPANY.
STAY CLEAR FROM BUILDINGS UNDER CONSTRUCTION DURING HIGH WINDS...AS
THEY CAN EASILY COLLAPSE. TRAVELING ON NORTH SOUTH ROADS NEAR THE
MOUNTAINS ALONG THE FRONT RANGE DURING A HIGH WIND EPISODE CAN ALSO
BE DANGEROUS.  IF YOU DRIVE A LIGHTWEIGHT OR HIGH PROFILE
VEHICLE...YOU MAY WANT TO WAIT UNTIL THE HIGH WINDS DIE DOWN.

CAN EASILY COLLAPSE. TRAVELING ON NORTH SOUTH ROADS NEAR THE
MOUNTAINS ALONG THE FRONT RANGE DURING A HIGH WIND EPISODE CAN ALSO
BE DANGEROUS.  IF YOU DRIVE A LIGHTWEIGHT OR HIGH PROFILE VEHICLE,
YOU MAY WANT TO WAIT UNTIL THE HIGH WINDS DIE DOWN.

...WIDESPREAD HIGH WINDS VISIT COLORADO DURING THE WINTER...

GOVERNOR JOHN HICKENLOOPER HAS PROCLAIMED THIS WEEK THROUGH OCTOBER
5TH AS WINTER WEATHER AWARENESS WEEK IN COLORADO.

THE TWO MAIN CAUSES OF HIGH WINDS IN COLORADO DURING THE COLD SEASON
RE THE AIR PRESSURE DIFFERENCE BETWEEN STRONG LOW PRESSURE AND COLD
HIGH PRESSURE SYSTEMS, AND CHINOOK WINDS DEVELOPING ACROSS THE FRONT
RANGE AND OTHER EASTERN MOUNTAIN RANGES.

A STRONG, COLD HIGH PRESSURE SYSTEM MOVING IN FROM THE NORTH AND
ETTING UP TO THE WEST OF THE ROCKIES CAN GENERATE A DAMAGING WIND
DOWN THE LEEWARD SLOPES OF THE MOUNTAINS, KNOWN AS A BORA. THESE
EPISODES FEATURE WIDESPREAD HIGH WINDS FROM THE WEST OR NORTHWEST
INTO THE ADJACENT PLAINS AT SPEEDS WHICH CAN EXCEED 100 MPH. MUCH
MORE RARE ARE THOSE EPISODES WHEN LOW PRESSURE IS ACROSS THE
ROCKIES, AND STRONG, COLD HIGH PRESSURE IS ACROSS THE GREAT PLAINS.
THE RESULT IS DAMAGING WINDS FROM THE EAST ACROSS THE WESTERN SLOPES
OF MOUNTAIN RANGES AND ADJACENT VALLEYS.

MID AND UPPER LEVEL WINDS OVER COLORADO ARE MUCH STRONGER IN THE
INTER THAN IN THE WARM SEASON, BECAUSE OF THE HUGE DIFFERENCE IN
TEMPERATURE FROM NORTH TO SOUTH ACROSS NORTH AMERICA.  WEST WINDS,
UNDER CERTAIN CONDITIONS, CAN BRING WARM, DRY CHINOOK WINDS PLOWING
DOWN THE SLOPES OF THE EASTERN MOUNTAINS. THESE WINDS CAN EXCEED 100
MPH IN EXTREME CASES, BRINGING THE POTENTIAL FOR WIDESPREAD DAMAGE.
WINDS OF 60 TO NEAR 100 MPH WILL OCCUR IN AND NEAR THE FOOTHILLS IN
AREAS SUCH AS FORT COLLINS, BOULDER, DENVER, COLORADO SPRINGS, CANON
CITY, WESTCLIFFE, WALSENBURG AND TRINIDAD. THE AREAS AROUND BOULDER
AND WESTCLIFFE ARE ESPECIALLY PRONE TO THESE EXTREME WIND EPISODES.

DANGERS FROM HIGH WINDS INCLUDE FLYING DEBRIS, REDUCED VISIBILITY UE
TO DUST, DAMAGED OR DESTROYED STRUCTURES, DOWNED POWER LINES, AND
OVERTURNED VEHICLES.  THE NATIONAL WEATHER SERVICE WILL ISSUE A HIGH
WIND WATCH WHEN THERE IS AROUND A 50 PERCENT CHANCE FOR HIGH WINDS
TO DEVELOP DURING THE NEXT DAY OR TWO. WHEN THE THREAT BECOMES MORE
CERTAIN IN A SPECIFIC AREA, A HIGH WIND WARNING WILL BE ISSUED.
COLD STRONG WINDS CAN ALSO BRING DANGEROUSLY LOW WIND CHILL VALUES,
PROMPTING A WIND CHILL ADVISORY OR WIND CHILL WARNING.

IF HIGH WINDS ARE FORECAST FOR YOUR AREA, YOU SHOULD BRING
LIGHTWEIGHT BJECTS INDOORS, OR TIE THEM DOWN OUTDOORS, OR MOVE THEM
SO THEY DO NOT BECOME DANGEROUS MISSILES.  ANY DOWNED POWER LINES
SHOULD NOT BE APPROACHED. INSTEAD CALL THE UTILITY COMPANY. STAY
CLEAR FROM BUILDINGS UNDER CONSTRUCTION DURING HIGH WINDS, AS THEY
CAN EASILY COLLAPSE. TRAVELING ON NORTH SOUTH ROADS NEAR THE
MOUNTAINS ALONG THE FRONT RANGE DURING A HIGH WIND EPISODE CAN ALSO
BE DANGEROUS.  IF YOU DRIVE A LIGHTWEIGHT OR HIGH PROFILE VEHICLE,
YOU MAY WANT TO WAIT UNTIL THE HIGH WINDS DIE DOWN.
