TROPICAL CYCLONE WARNING BULLETIN
 
HERE IS THE LATEST TROPICAL CYCLONE WARNING BULLETIN ISSUED
BY THE HONG KONG OBSERVATORY.
 
THE INCREASING GALE OR STORM SIGNAL, NO. 9, WAS ISSUED AT
1:40 A.M.
 
THIS MEANS THAT WINDS ARE EXPECTED TO INCREASE
SIGNIFICANTLY AS RAGASA MOVES CLOSER TO HONG KONG.
 
AT 2 A.M., SUPER TYPHOON RAGASA WAS CENTRED ABOUT 150
KILOMETRES SOUTH-SOUTHEAST OF HONG KONG (NEAR 21.1 DEGREES
NORTH 114.9 DEGREES EAST) AND IS FORECAST TO MOVE
WEST-NORTHWEST AT ABOUT 22 KILOMETRES PER HOUR EDGING
CLOSER TO THE VICINITY OF THE PEARL RIVER ESTUARY TO THE
COAST OF WESTERN GUANGDONG.

 

CURRENTLY, GALE FORCE WINDS ARE AFFECTING MANY PLACES
LOCALLY WITH SOME PLACES REACHING STORM FORCE. RAGASA IS
EXPECTED TO BE CLOSEST TO HONG KONG THIS MORNING (24
SEPTEMBER), SKIRTING AROUND 100 KILOMETRES TO THE SOUTH OF
THE TERRITORY. WITH THE HURRICANE FORCE WINDS OF RAGASA
EDGING CLOSER GRADUALLY, LOCAL WINDS WILL CONTINUE TO
STRENGTHEN. DEPENDING ON THE CHANGE IN LOCAL WIND
CONDITIONS, THE OBSERVATORY WILL ASSESS THE NEED OF ISSUING
THE HURRICANE SIGNAL, NO. 10. 
 
LOCAL WINDS WILL VEER GRADUALLY FROM NORTHERLIES TO EAST TO
SOUTHEASTERLIES THIS MORNING. AREAS WHICH WERE PREVIOUSLY
SHELTERED MAY BECOME EXPOSED. MEMBERS OF THE PUBLIC SHOULD
STAY ON HIGH ALERT. 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 RISE IN
WATER LEVEL CAN REACH AROUND 2 METRES OVER THE COAST OF
HONG KONG TODAY. THE WATER LEVEL WILL START TO RISE AFTER
AROUND 6 A.M. IN THE MORNING. IT WILL REACH THE MAXIMUM
LATER IN THE MORNING TO EARLY AFTERNOON, GENERALLY TO
AROUND 3.5 TO 4 METRES ABOVE CHART DATUM. THE WATER LEVEL
AT TOLO HARBOUR MAY EVEN REACH 4 TO 5 METRES ABOVE CHART
DATUM.

 

IN THE PAST HOUR, THE MAXIMUM SUSTAINED WINDS RECORDED AT
WAGLAN ISLAND, TATE'S CAIRN AND CHEUNG CHAU WERE 100, 99
AND 76 KILOMETRES PER HOUR WITH MAXIMUM GUSTS EXCEEDING
120, 132 AND 101 KILOMETRES PER HOUR RESPECTIVELY.

FLOODING OR BACKFLOW OF SEAWATER. YOU SHOULD AVOID GOING TO
