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 1 P.M., SUPER TYPHOON RAGASA WAS CENTRED ABOUT 170
KILOMETRES SOUTHWEST OF HONG KONG (NEAR 21.4 DEGREES NORTH
112.8 DEGREES EAST) AND IS FORECAST TO MOVE WEST OR
WEST-NORTHWEST AT ABOUT 22 KILOMETRES PER HOUR EDGING
CLOSER TO THE VICINITY OF THE WESTERN COAST OF GUANGDONG.

 

WITH RAGASA MOVING TOWARDS THE COAST OF WESTERN GUANGDONG,
ITS ASSOCIATED HURRICANE FORCE WINDS WILL ALSO DEPART FROM
HONG KONG GRADUALLY. THE OBSERVATORY WILL ISSUE THE NO. 8
SOUTHEAST GALE OR STORM SIGNAL AT 1:20 P.M. TODAY.
 
LOCAL WEATHER WILL BE PERSISTENTLY ADVERSE TODAY WITH
FREQUENT HEAVY SQUALLY SHOWERS AND THUNDERSTORMS. SEAS WILL
BE PHENOMENAL WITH SWELLS. THERE WILL BE OVERTOPPING WAVES
OVER THE SHORELINE, WHICH WILL BE PARTICULARLY SIGNIFICANT
ALONG THE EASTERN AND SOUTHERN COASTS. MEMBERS OF THE
PUBLIC SHOULD STAY AWAY FROM THE SHORELINE AND NOT ENGAGE
IN WATER SPORTS.
 
THE STORM SURGE BROUGHT BY RAGASA CAUSED A GENERAL RISE OF
MORE THAN 1.5 METRES IN WATER LEVELS OVER THE TERRITORY.
THE WATER LEVEL RECORDED AT VICTORIA HARBOUR WAS ONCE ABOUT
3.4 METRES ABOVE CHART DATUM, WHILE THE MAXIMUM WATER LEVEL
AT TAI PO KAU AND TSIM BEI TSUI TIDE STATION WAS ABOUT 3.8
METRES ABOVE CHART DATUM. LOCAL WATER LEVELS OVER THE
COASTAL AREAS WILL FALL PROGRESSIVELY IN THE AFTERNOON.

 

IN THE PAST HOUR, THE MAXIMUM SUSTAINED WINDS RECORDED AT
NGONG PING, CHEUNG CHAU AND TAP MUN WERE 135, 113 AND 92
KILOMETRES PER HOUR WITH MAXIMUM GUSTS EXCEEDING 187, 136
AND 110 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. PEOPLE OUTDOORS SHOULD FIND A SAFE PLACE NOW AND REMAIN
THERE UNTIL THE DANGER IS OVER.

FLOODING OR BACKFLOW OF SEAWATER. YOU SHOULD AVOID GOING TO
LIKELY AFFECTED LOW-LYING AREAS AND STAY AWAY FROM
DANGEROUS PLACES.

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.
 
5. 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.
