HOURLY READINGS


 

AT NOON AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 27 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 96 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 0.2. THE INTENSITY OF UV RADIATION WAS LOW.

 

AN AREA OF LOW PRESSURE IS MOVING ACROSS THE VICINITY OF
THE PEARL RIVER ESTUARY. ITS INTENSE RAIN BAND IS AFFECTING
HONG KONG. WHETHER THE BLACK RAINSTORM WARNING SIGNAL NEEDS
TO BE ISSUED DEPENDS ON THE DEVELOPMENT OF THE AREAS OF THE
RAIN BAND. MEMBERS OF THE PUBLIC SHOULD BE ON THE ALERT AND
TAKE NOTE OF THE LATEST WEATHER INFORMATION.
  
A BROAD TROUGH OF LOW PRESSURE OVER THE NORTHERN PART OF
THE SOUTH CHINA SEA IS BRINGING HEAVY SHOWERS AND SQUALLY
THUNDERSTORMS TO THE COAST OF GUANGDONG. AN AREA OF LOW
PRESSURE OVER THE TROUGH HAS ALREADY ENTERED THE EASTERN
PART OF HONG KONG. UNDER THE INFLUENCE OF ITS ASSOCIATED
BAND OF THUNDERY SHOWERS, WINDS WILL BE OCCASIONALLY STRONG
OVER PARTS OF THE TERRITORY. HOWEVER, ITS SUSTAINED WINDS
AND CONVECTIONS ARE RELATIVELY WEAK GENERALLY. IT HAS NOT
YET REACHED THE INTENSITY OF A TROPICAL CYCLONE. THE AREA
OF LOW PRESSURE IS CURRENTLY LOCATED AT AROUND 20
KILOMETRES EAST-NORTHEAST OF THE HONG KONG OBSERVATORY. IT
IS EXPECTED TO MAINTAIN A RELATIVELY WEAK SYSTEM AND MAY
MOVE WEST ACROSS HONG KONG. THE OBSERVATORY WILL CLOSELY
MONITOR ITS POSSIBLE DEVELOPMENT AND MOVEMENT. MEMBERS OF
THE PUBLIC PLEASE TAKE NOTE OF THE LATEST WEATHER
INFORMATION.

 

PLEASE BE REMINDED THAT:

 

THE RED RAINSTORM WARNING SIGNAL HAS BEEN ISSUED.
THE THUNDERSTORM WARNING HAS BEEN ISSUED. IT WILL REMAIN
EFFECTIVE UNTIL 1:30 P.M. TODAY. A FEW SQUALLY
THUNDERSTORMS ARE EXPECTED TO OCCUR OVER HONG KONG.
