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 10 P.M., SUPER TYPHOON SAOLA WAS CENTRED ABOUT 40
KILOMETRES SOUTH-SOUTHEAST OF HONG KONG OBSERVATORY (NEAR
22.0 DEGREES NORTH 114.3 DEGREES EAST) AND IS FORECAST TO
MOVE WEST AT ABOUT 14 KILOMETRES PER HOUR ACROSS THE
VICINITY OF THE PEARL RIVER ESTUARY.

 

THE EYEWALL OF SAOLA IS NOW MOVING ACROSS HONG KONG.
HURRICANE FORCE WINDS ARE AFFECTING MANY PLACES. SAOLA WILL
BE CLOSEST TO HONG KONG IN THE NEXT FEW HOURS, SKIRTING
AROUND 40 KILOMETRES TO THE SOUTH OF THE HONG KONG
OBSERVATORY. THE HURRICANE SIGNAL, NO. 10 WILL REMAIN IN
FORCE FOR SOME TIME. NORTHEASTERLY WINDS WILL CHANGE
GRADUALLY TO EAST TO SOUTHEASTERLIES. AREAS WHICH WERE
PREVIOUSLY SHELTERED MAY BECOME EXPOSED. MEMBERS OF THE
PUBLIC SHOULD STAY ON HIGH ALERT. YOU ARE ADVISED TO STAY
WHERE YOU ARE IF PROTECTED AND BE PREPARED FOR DESTRUCTIVE
WINDS. 
 
UNDER THE INFLUENCE OF STORM SURGE, THE SEA LEVELS OVER THE
COASTAL AREAS OF HONG KONG ARE RISING. AT PRESENT, THE
WATER LEVEL AT TOLO HARBOUR IS AROUND 3 METRES. IT IS
EXPECTED THAT THE MAXIMUM WATER LEVEL WILL BE 5 TO 6 METRES
ABOVE CHART DATUM BEFORE MIDNIGHT, WHICH IS ABOUT 3 TO 4
METRES ABOVE NORMAL TIDE LEVEL. IT MAY REACH A HISTORICAL
RECORD SINCE THE AVAILABILITY OF INSTRUMENTAL DATA IN THAT
REGION. THERE WILL BE SERIOUS FLOODING IN LOW-LYING COASTAL
AREAS SUCH AS SHATIN, TAI PO, SHA TAU KOK, SAI KUNG, ETC.
THE MAXIMUM WATER LEVEL AT VICTORIA HARBOUR WILL BE SOME 3
METRES ABOVE CHART DATUM. THE WATER LEVEL AT TAI O WILL
ALSO RISE TO SOME 3 METRES ABOVE CHART DATUM AROUND 9 A.M.
TOMORROW MORNING (2 SEPTEMBER).

 

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. THE OBSERVATORY MAKES A SPECIAL
APPEAL TO THE MEMBERS OF THE PUBLIC TO STAY IN SAFE PLACE
INDOOR, AND NOT TO GO OUTSIDE.

 

IN THE PAST HOUR, THE MAXIMUM SUSTAINED WINDS RECORDED AT
WAGLAN ISLAND, TATE'S CAIRN AND GREEN ISLAND WERE 159, 144
AND 128 KILOMETRES PER HOUR WITH MAXIMUM GUSTS EXCEEDING
183, 183 AND 156 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. PEOPLE OUTDOORS SHOULD FIND A SAFE PLACE NOW AND REMAIN
THERE UNTIL THE DANGER IS OVER.
 
4. 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.
