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 4 P.M., SUPER TYPHOON RAGASA WAS CENTRED ABOUT 340
KILOMETRES SOUTHEAST OF HONG KONG (NEAR 20.5 DEGREES NORTH
116.8 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.

 

IN THE PAST FEW HOURS, RAGASA CONTINUED TO MOVE CLOSER TO
HONG KONG. ACCORDING TO THE PRESENT FORECAST, RAGASA WILL
MAINTAIN SUPER TYPHOON INTENSITY AND 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 IN THE LATTER PART OF TONIGHT AND AT FIRST OF
TOMORROW.
 
RAGASA HAS AN EXTENSIVE CIRCULATION WITH FIERCE WINDS. ITS
OUTER RAINBANDS HAVE EDGED CLOSER TO THE VICINITY OF THE
PEARL RIVER ESTUARY GRADUALLY. LOCALLY, OCCASIONAL GALES
ARE ALREADY STARTING TO AFFECT HIGH GROUNDS. THE WEATHER IS
EXPECTED TO START DETERIORATING RAPIDLY LATER TODAY, 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 TO
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.
