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 A.M., SUPER TYPHOON RAGASA WAS CENTRED ABOUT 140
KILOMETRES SOUTHWEST OF HONG KONG (NEAR 21.3 DEGREES NORTH
113.4 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.

 

RAGASA HAS STARTED TO DEPART FROM HONG KONG, BUT ITS
ASSOCIATED HURRICANE FORCE WINDS ARE STILL AFFECTING THE
SOUTHWESTERN PART OF THE TERRITORY OCCASIONALLY. THE
HURRICANE SIGNAL, NO. 10 WILL REMAIN IN FORCE FOR SOME TIME.
 
LOCAL WINDS ARE EXPECTED TO BECOME SOUTHEASTERLIES
GRADUALLY. MEMBERS OF THE PUBLIC SHOULD BE ON HIGH ALERT
AND BEWARE OF DESTRUCTIVE WINDS. 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.
 
RAGASA IS BRINGING SIGNIFICANT STORM SURGE TO THE
TERRITORY. THE WATER LEVEL OVER THE COAST OF HONG KONG HAS
GENERALLY RISEN TO MORE THAN 3 METRES ABOVE CHART DATUM AT
9 A.M. MEANWHILE, THE WATER LEVEL OVER THE COAST IS STILL
RISING PROGRESSIVELY AND IS EXPECTED TO REACH THE MAXIMUM

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
