TROPICAL CYCLONE WARNING BULLETIN (SIGNAL NO. 8)


 

TROPICAL CYCLONE WARNING BULLETIN
 
HERE IS THE LATEST TROPICAL CYCLONE WARNING BULLETIN ISSUED
BY THE HONG KONG OBSERVATORY.
 
THE NO. 8 NORTHWEST GALE OR STORM SIGNAL IS IN FORCE.
 
THIS MEANS THAT WINDS WITH MEAN SPEEDS OF 63 KILOMETRES PER
HOUR OR MORE ARE EXPECTED FROM THE NORTHWEST QUARTER.
 
AT 10 P.M., SUPER TYPHOON RAGASA WAS CENTRED ABOUT 240
KILOMETRES SOUTHEAST OF HONG KONG (NEAR 20.8 DEGREES NORTH
115.8 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.

 

ACCORDING TO THE PRESENT FORECAST, RAGASA WILL BE CLOSEST
TO THE VICINITY OF THE PEARL RIVER ESTUARY TOMORROW (24
SEPTEMBER) MORNING. LOCAL WINDS WILL STRENGTHEN FURTHER.
DEPENDING ON THE DISTANCE BETWEEN RAGASA AND HONG KONG, AS
WELL AS THE CHANGE IN LOCAL WIND CONDITIONS, THE
OBSERVATORY WILL ASSESS THE NEED OF ISSUING HIGHER TROPICAL
CYCLONE WARNING SIGNALS BETWEEN 11 P.M. TONIGHT AND 3 A.M.
TOMORROW.
 
RAGASA HAS AN EXTENSIVE CIRCULATION WITH FIERCE WINDS. ITS
OUTER RAINBANDS ARE BRINGING SQUALLY SHOWERS TO EASTERN
GUANGDONG AND THE VICINITY OF THE PEARL RIVER ESTUARY.
LOCAL WINDS ARE GENERALLY STRENGTHENING AND THERE ARE
OCCASIONAL GALES ON HIGH GROUND. THE WEATHER IS EXPECTED TO
DETERIORATE RAPIDLY OVERNIGHT, WITH WINDS STRENGTHENING
QUICKLY. THE WEATHER WILL BE PERSISTENTLY ADVERSE TOMORROW.
GALE TO STORM FORCE WINDS WILL PREVAIL LOCALLY, AND WINDS
WILL REACH HURRICANE FORCE OFFSHORE AND ON HIGH GROUND AT
FIRST. THERE WILL BE 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 TOMORROW. 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
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. MEMBERS OF THE PUBLIC SHOULD TAKE NECESSARY
PRECAUTIONS.

 

IN THE PAST HOUR, THE MAXIMUM SUSTAINED WINDS RECORDED AT
TATE'S CAIRN AND WAGLAN ISLAND WERE 85 AND 69 KILOMETRES
PER HOUR WITH MAXIMUM GUSTS EXCEEDING 103 AND 82 KILOMETRES
PER HOUR RESPECTIVELY.
