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 P.M., SUPER TYPHOON SAOLA WAS CENTRED ABOUT 30
KILOMETRES SOUTH-SOUTHWEST OF HONG KONG OBSERVATORY (NEAR
22.0 DEGREES NORTH 114.1 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 IS
CLOSEST TO HONG KONG AT PRESENT, SKIRTING AROUND 30
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 OF SAOLA. 
 
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 RISES ABOVE 3 METRES. THE
MAXIMUM WATER LEVEL IS EXPECTED TO BE 5 TO 6 METRES ABOVE
CHART DATUM BEFORE MIDNIGHT, AND 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. 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, CHEUNG CHAU BEACH AND GREEN ISLAND WERE 159,
141 AND 140 KILOMETRES PER HOUR WITH MAXIMUM GUSTS
EXCEEDING 179, 175 AND 180 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.
