HOURLY READINGS


 

AT 10 A.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 28 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 90 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 1. THE INTENSITY OF UV RADIATION WAS LOW.

 

THE AREA OF LOW PRESSURE OVER THE NORTHERN PART OF THE
SOUTH CHINA SEA WILL BE CLOSEST TO HONG KONG IN THE NEXT
COUPLE OF HOURS, SKIRTING AT AROUND 50 KILOMETRES TO THE
SOUTH OF THE TERRITORY. 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. UNDER THE INFLUENCE OF THE AREA OF LOW
PRESSURE, THE WATER LEVELS OVER SOME COASTAL AREAS THIS
MORNING WERE SLIGHTLY HIGHER THAN NORMAL. THE WATER LEVEL
AT QUARRY BAY REACHED AROUND 2.7 METRES ABOVE CHART DATUM,
BUT IT IS EXPECTED TO FALL GRADUALLY LATER. 
 
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. UNDER THE
INFLUENCE OF THE ACTIVE SOUTHWESTERLY AIRSTREAM TO ITS
EASTERN AND SOUTHERN SIDES, LOCAL WINDS WILL STRENGTHEN
GRADUALLY LATER TODAY. DEPENDING ON THE CHANGE IN LOCAL
WIND CONDITIONS, THE OBSERVATORY WILL CONSIDER ISSUING THE
STRONG MONSOON SIGNAL BY THEN. 
 
MEANWHILE, 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 GRAUDALLY DURING THE DAY TODAY. THERE MAY BE A
NEED TO ISSUE RAINSTORM WARNING SIGNALS OR LOCALISED HEAVY
RAIN ADVISORY. UNDER THE INFLUENCE OF THE 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 HAS BEEN ISSUED. IT WILL REMAIN
EFFECTIVE UNTIL 11:30 A.M. TODAY. ISOLATED SQUALLY
THUNDERSTORMS ARE EXPECTED TO OCCUR OVER HONG KONG.
