AT 5 A.M., SUPER TYPHOON RAGASA WAS CENTRED ABOUT 120

COAST OF WESTERN GUANGDONG.

 

THE CIRCULATION OF RAGASA IS EXTENSIVE AND ITS WINDS ARE
FIERCE. IT WILL BE CLOSEST TO HONG KONG IN THE NEXT FEW
HOURS, SKIRTING AROUND 100 KILOMETRES TO THE SOUTH OF THE
TERRITORY, POSING A SERIOUS THREAT TO HONG KONG. HURRICANE
FORCE WINDS ARE CURRENTLY AFFECTING THE SOUTHERN PART OF
THE TERRITORY AND HIGH GROUND. AS RAGASA FURTHER EDGES
NEAR, ITS HURRICANE FORCE WINDS WILL AFFECT MORE AREAS OF
HONG KONG. MEMBERS OF THE PUBLIC SHOULD BE ON HIGH ALERT
AND BEWARE OF DESTRUCTIVE WINDS. THE HURRICANE SIGNAL, NO.
10 WILL REMAIN IN FORCE FOR SOME TIME. 
 
LOCAL WINDS WILL VEER GRADUALLY FROM NORTHEASTERLIES TO
SOUTHEASTERLIES THIS MORNING. AREAS WHICH WERE PREVIOUSLY
SHELTERED MAY BECOME EXPOSED. 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. 
 
UNDER THE INFLUENCE OF SIGNIFICANT STORM SURGE, THE WATER

TO 3 METRES OVER THE COAST OF HONG KONG TODAY, AND WILL

2. PEOPLE OUTDOORS SHOULD FIND A SAFE PLACE NOW AND REMAIN
