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, WAS ISSUED AT 9:20 A.M.
 
THIS MEANS THAT WINDS WITH MEAN SPEEDS OF 118 KILOMETRES
PER HOUR OR MORE ARE EXPECTED.
 
AT 9 A.M., TYPHOON WIPHA WAS CENTRED ABOUT 70 KILOMETRES
SOUTHEAST OF HONG KONG OBSERVATORY (NEAR 21.8 DEGREES NORTH
114.6 DEGREES EAST) AND IS FORECAST TO MOVE WEST OR
WEST-NORTHWEST AT ABOUT 25 KILOMETRES PER HOUR EDGING
CLOSER TO THE VICINITY OF THE PEARL RIVER ESTUARY.

 

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. HURRICANE FORCE WINDS ARE AFFECTING THE SOUTHERN PART
OF THE TERRITORY. THE HURRICANE SIGNAL, NO. 10 IS EXPECTED
TO REMAIN IN FORCE FOR SOME TIME. LOCAL WINDS WILL CHANGE
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, TATE'S CAIRN AND GREEN ISLAND WERE 103, 97
AND 66 KILOMETRES PER HOUR WITH MAXIMUM GUSTS EXCEEDING
120, 125 AND 87 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.
