HOURLY READINGS


 

AT 8 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 30 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 79 PER
CENT.

 

THE TROPICAL CYCLONE NEAR LUZON HAS ENTERED WITHIN 800
KILOMETRES OF HONG KONG. THE OBSERVATORY WILL ISSUE THE
STANDBY SIGNAL, NO. 1 AT 9:20 P.M. TONIGHT.
 
THE TROPICAL CYCLONE IS EXPECTED TO MOVE ACROSS THE
NORTHEASTERN PART OF THE SOUTH CHINA SEA IN THE NEXT COUPLE
OF DAYS. IT WILL INTENSIFY GRADUALLY AND MOVE IN THE
GENERAL DIRECTION OF THE COAST OF EASTERN GUANGDONG. UNDER
THE INFLUENCE OF THE NORTHEAST MONSOON, THE TROPICAL
CYCLONE WILL THEN TURN WESTWARDS, EDGING CLOSER TO THE
VICINITY OF THE PEARL RIVER ESTUARY. HOWEVER, THERE ARE
UNCERTAINTIES IN ITS LANDFALL POSITION AND INTENSITY. AS
ITS CIRCULATION IS RELATIVELY SMALL, THE TROPICAL CYCLONE
WILL ONLY BRING SIGNIFICANT IMPACT TO LOCAL WEATHER WHEN IT
GETS RELATIVELY CLOSE TO HONG KONG. DEPENDING ON THE
INTENSITY OF THE TROPICAL CYCLONE, THE DISTANCE OF ITS
STRONG WINDS FROM HONG KONG AND THE CHANGE IN LOCAL WIND
CONDITIONS, THE OBSERVATORY WILL ASSESS THE NEED TO ISSUE
HIGHER TROPICAL CYCLONE WARNING SIGNALS LATER ON THURSDAY
(18 SEPTEMBER) TO FRIDAY (19 SEPTEMBER).
 
UNDER THE INFLUENCE OF THE OUTER RAINBANDS ASSOCIATED WITH
THE TROPICAL CYCLONE, THERE WILL BE MORE SHOWERS AND WINDS
WILL STRENGTHEN GRADUALLY LATER ON FRIDAY. THERE WILL BE
OCCASIONAL SQUALLY SHOWERS AND THUNDERSTORMS OVER THE
WEEKEND, SHOWERS WILL BE HEAVIER AT TIMES, AND THERE WILL
BE SWELLS.
 
ON THE OTHER HAND, ANOTHER TROPICAL CYCLONE IS EXPECTED TO
FORM OVER THE WESTERN NORTH PACIFIC TO THE EAST OF THE
PHILIPPINES TODAY AND TOMORROW. IT WILL INTENSIFY
SIGNIFICANTLY AND MOVE ACROSS THE VICINITY OF LUZON STRAIT.
IT WILL ENTER THE NORTHERN PART OF THE SOUTH CHINA SEA
EARLY NEXT WEEK AND EDGE CLOSER TO THE COAST OF SOUTHERN
CHINA. UNDER THE INFLUENCE OF THE EXTENSIVE CIRCULATION OF
THE TROPICAL CYCLONE, THE WEATHER WILL DETERIORATE
SIGNIFICANTLY OVER THE REGION MIDWEEK NEXT WEEK. WINDS WILL
STRENGTHEN AGAIN WITH HEAVY SQUALLY SHOWERS AND
THUNDERSTORMS. SEAS WILL BE ROUGH WITH SWELLS. SINCE STORM
SURGE MAY BE QUITE SIGNIFICANT BY THEN, THERE MAY BE
FLOODING OVER THE COASTAL AREAS.
 
MEMBERS OF THE PUBLIC SHOULD TAKE NOTE OF THE LATEST
WEATHER INFORMATION FROM THE OBSERVATORY.

 

PLEASE BE REMINDED THAT:

 

THE VERY HOT WEATHER WARNING IS NOW IN FORCE. THE PUBLIC
SHOULD BEWARE OF HEAT STROKE AND DRINK MORE WATER.
