HOURLY READINGS


 

AT 3 A.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 28 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 88 PER
CENT.

 

THE AREA OF LOW PRESSURE OVER THE NORTHERN PART OF THE
SOUTH CHINA SEA HAS MOVED TO WITHIN 100 KILOMETRES SOUTH OF
HONG KONG. HOWEVER, ITS STRUCTURE REMAINS RELATIVELY LOOSE.
WINDS AND CONVECTIONS ARE RELATIVELY WEAK NEAR ITS CENTRE.
IT HAS NOT YET REACHED THE INTENSITY OF A TROPICAL CYCLONE.
ACCORDING TO THE PRESENT FORECAST, THE AREA OF LOW PRESSURE
WILL MOVE NORTHWEST IN THE GENERAL DIRECTION OF THE
VICINITY OF THE PEARL RIVER ESTUARY THIS MORNING. AS THE
AREA OF LOW PRESSURE EDGES CLOSER TO HONG KONG, WINDS MAY
SLIGHTLY STRENGTHEN OVER PARTS OF THE TERRITORY. THE
OBSERVATORY WILL CLOSELY MONITOR ITS DEVELOPMENT AND
MOVEMENT, AND THE CHANGE IN LOCAL WIND CONDITIONS, FOR
ASSESSING THE NEED OF ISSUING TROPICAL CYCLONE WARNING
SIGNALS. MEMBERS OF THE PUBLIC PLEASE PAY ATTENTION TO THE
LATEST WEATHER INFORMATION FROM THE OBSERVATORY. 
SINCE THE RAINBANDS ASSOCIATED WITH THE AREA OF LOW
PRESSURE ARE MAINLY LOCATED TO ITS SOUTHERN SIDE, HEAVY
SHOWERS AND SQUALLY THUNDERSTORMS ARE EXPECTED TO AFFECT
HONG KONG DURING THE DAY TODAY. THERE MAY BE A NEED TO
ISSUE RAINSTORM WARNING SIGNALS OR LOCALISED HEAVY RAIN
ADVISORY BY THEN. FLOODING MAY OCCUR IN SOME LOW-LYING
AREAS. UNDER THE INFLUENCE OF AN ACTIVE SOUTHWESTERLY
AIRSTREAM, SHOWERS WILL BE HEAVIER IN SOME AREAS AT FIRST
TOMORROW (15 JULY) AND THERE WILL STILL BE OCCASIONAL
STRONG WINDS OFFSHORE.

 

PLEASE BE REMINDED THAT:

 

THE THUNDERSTORM WARNING WAS ISSUED AT 3:45 A.M. IT WILL
REMAIN EFFECTIVE UNTIL 5:45 A.M. TODAY. ISOLATED
THUNDERSTORMS ARE EXPECTED TO OCCUR OVER HONG KONG.
