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 3 P.M., SEVERE TYPHOON MANGKHUT WAS CENTRED ABOUT 110
KILOMETRES SOUTHWEST OF HONG KONG (NEAR 21.6 DEGREES NORTH
113.4 DEGREES EAST) AND IS FORECAST TO MOVE WEST-NORTHWEST
AT ABOUT 30 KILOMETRES PER HOUR TOWARDS THE COAST TO THE
WEST OF THE PEARL RIVER ESTUARY.

 

ACCORDING TO THE PRESENT FORECAST TRACK, MANGKHUT IS NOW
SKIRTING WITHIN ABOUT 100 KILOMETRES TO THE SOUTH OF HONG
KONG. THE HURRICANE SIGNAL, NO. 10 WILL REMAIN IN FORCE IN
THE AFTERNOON. 
 
THE CIRCULATION OF MANGKHUT IS EXTENSIVE. DESTRUCTIVE STORM
TO HURRICANE FORCE WINDS ARE AFFECTING HONG KONG. IN THE
PAST HOUR, THE MAXIMUM SUSTAINED WINDS RECORDED AT TATE'S
CAIRN, CHEUNG CHAU AND TAI MEI TUK WERE 170, 165 AND 145
KILOMETRES PER HOUR WITH MAXIMUM GUSTS 216, 213 AND 176
KILOMETRES PER HOUR RESPECTIVELY.
 
MANGKHUT'S INTENSE RAINBANDS ARE AFFECTING HONG KONG,
BRINGING FREQUENT SQUALLS AND HEAVY RAIN. SEA WILL BE
PHENOMENAL WITH SWELLS. LOCAL WINDS WILL CHANGE GRADUALLY
FROM EASTERLIES TO SOUTHEASTERLIES. MEMBERS OF THE PUBLIC
SHOULD STAY ON HIGH ALERT AND TAKE PRECAUTIONS AGAINST THE
DESTRUCTIVE WINDS FROM THE SOUTHEAST.
 
UNDER THE INFLUENCE OF STORM SURGE, THE WATER LEVEL AT
VICTORIA HARBOUR HAS EXCEEDED 3.5 METRES ABOVE CHART DATUM
AND IS STILL RISING; WHEREAS THE WATER LEVEL AT TOLO
HARBOUR HAS REACHED ABOUT 4.5 METRES ABOVE CHART DATUM. A
HIGH WATER LEVEL OF ABOUT 3.8 METRES OR MORE ABOVE CHART
DATUM IS EXPECTED AT TAI O IN THE NEXT FEW HOURS. THE HIGH
WATER LEVEL TOGETHER WITH THE HEAVY RAIN WILL CAUSE SEVERE
FLOODING IN LOW-LYING AREAS. 
 
THE OBSERVATORY MAKES A SPECIAL APPEAL TO THE MEMBERS OF
THE PUBLIC TO STAY IN SAFE PLACE INDOOR, AND NOT TO GO
OUTSIDE.

 

(PRECAUTIONARY ANNOUNCEMENTS)
 
1. 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. WITH CHANGE IN WIND DIRECTION, VIOLENT WINDS WILL COME
FROM A DIFFERENT DIRECTION. REMAIN WHERE YOU ARE IF
PROTECTED AND BE PREPARED FOR DESTRUCTIVE WINDS AND THE
CHANGE IN WIND DIRECTIONS.
 
4. PEOPLE OUTDOORS SHOULD FIND A SAFE PLACE NOW AND REMAIN
THERE UNTIL THE DANGER IS OVER.
 
5. 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.
