TROPICAL CYCLONE WARNING BULLETIN (SIGNAL NO. 10)


 

TROPICAL CYCLONE WARNING BULLETIN
 
HERE IS THE LATEST TROPICAL CYCLONE WARNING BULLETIN ISSUED
BY THE HONG KONG OBSERVATORY.
 
THE HURRICANE SIGNAL, NO. 10, IS IN FORCE.
 
THIS MEANS THAT WINDS WITH MEAN SPEEDS OF 118 KILOMETRES
PER HOUR OR MORE ARE EXPECTED.
 
AT 11 A.M., TYPHOON WIPHA WAS CENTRED ABOUT 60 KILOMETRES
SOUTH OF HONG KONG OBSERVATORY (NEAR 21.8 DEGREES NORTH
114.2 DEGREES EAST) AND IS FORECAST TO MOVE WEST OR
WEST-NORTHWEST AT ABOUT 25 KILOMETRES PER HOUR ACROSS THE
WATERS SOUTH OF HONG KONG.

 

WIPHA WILL BE CLOSEST TO HONG KONG IN THE NEXT COUPLE OF
HOURS, SKIRTING ABOUT 50 KILOMETRES TO THE SOUTH OF THE
HONG KONG OBSERVATORY, POSING CONSIDERABLE THREAT TO HONG
KONG. UNDER THE INFLUENCE OF ITS EYEWALL, HURRICANE FORCE
WINDS ARE AFFECTING PARTS OF THE TERRITORY. THE HURRICANE
SIGNAL, NO. 10 IS EXPECTED TO REMAIN IN FORCE UNTIL EARLY
THIS AFTERNOON. LOCAL WINDS ARE CHANGING GRADUALLY FROM
NORTHERLIES TO EAST TO SOUTHEASTERLIES. AREAS WHICH WERE
PREVIOUSLY SHELTERED MAY BECOME EXPOSED. MEMBERS OF THE
PUBLIC SHOULD STAY ON HIGH ALERT, STAY WHERE THEY ARE
SHELTERED AND BEWARE OF DESTRUCTIVE WINDS.
 
THE INTENSE RAINBANDS OF WIPHA ARE ALSO BRINGING FREQUENT
HEAVY SQUALLY SHOWERS TO HONG KONG. SEAS WILL BE PHENOMENAL
WITH SWELLS. MEMBERS OF THE PUBLIC ARE ADVISED TO STAY AWAY
FROM THE SHORELINE AND NOT TO ENGAGE IN WATER SPORTS. UNDER
THE INFLUENCE OF STORM SURGE, THE WATER LEVEL ROSE TO ABOUT
3 METRES ABOVE CHART DATUM AT TAI PO KAU THIS MORNING.
THERE MAY BE FLOODING OVER PARTS OF THE LOW-LYING COASTAL
AREAS IN THE TERRITORY.

 

IN THE PAST HOUR, THE MAXIMUM SUSTAINED WINDS RECORDED AT
WAGLAN ISLAND, GREEN ISLAND AND TATE'S CAIRN WERE 138, 124
AND 124 KILOMETRES PER HOUR WITH MAXIMUM GUSTS EXCEEDING
156, 167 AND 164 KILOMETRES PER HOUR RESPECTIVELY.

 

(PRECAUTIONARY ANNOUNCEMENTS)
 
1. DO NOT GO OUTSIDE. IF YOU ARE REASONABLY PROTECTED, STAY
WHERE YOU ARE. DO NOT TOUCH ELECTRIC CABLES THAT HAVE BEEN
BLOWN LOOSE.
 
2. STAY AWAY FROM EXPOSED WINDOWS AND DOORS BECAUSE GLASS,
ALREADY UNDER STRAIN FROM WIND PRESSURE, WILL SHATTER
EASILY IF HIT BY A FLYING OBJECT. MAKE SURE YOU HAVE A SAFE
PLACE TO SHELTER. YOU SHOULD ONLY FIX BROKEN WINDOWS AND
DOORS WHEN THERE IS NO DANGER IN DOING SO.
 
3. IF THE EYE OF THE TROPICAL CYCLONE PASSES DIRECTLY OVER
HONG KONG, THERE MAY BE A TEMPORARY LULL LASTING FROM A FEW
MINUTES TO SEVERAL HOURS. THIS WILL BE FOLLOWED BY A SUDDEN
RESUMPTION OF VIOLENT WINDS FROM A DIFFERENT DIRECTION.
REMAIN WHERE YOU ARE IF PROTECTED AND BE PREPARED FOR
DESTRUCTIVE WINDS AND THE CHANGE IN WIND DIRECTIONS.
 
4. SINCE SEAS ARE PHENOMENAL, AND THERE ARE SWELLS, THE
CURRENT IS STRONG WITH CHANGING DIRECTION. YOU ARE ADVISED
TO STAY AWAY FROM THE SHORELINE AND NOT TO ENGAGE IN WATER
SPORTS.
 
5. PEOPLE OUTDOORS SHOULD FIND A SAFE PLACE NOW AND REMAIN
THERE UNTIL THE DANGER IS OVER.
 
6. FLIGHTS AT HONG KONG INTERNATIONAL AIRPORT MAY BE
AFFECTED BY THE WEATHER. PLEASE CONTACT YOUR AIRLINE FOR
THE LATEST FLIGHT INFORMATION BEFORE DEPARTING FOR THE
AIRPORT.
 
7. TROPICAL CYCLONE BROUGHT DIFFERENT DEGREES OF DAMAGES TO
HONG KONG. THERE MAY BE HIDDEN DANGER. MEMBERS OF THE
PUBLIC SHOULD REMAIN ON THE ALERT FOR ASSURANCE OF PERSONAL
SAFETY.
