HOURLY READINGS


 

AT 6 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 31 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 70 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 0.4. THE INTENSITY OF UV RADIATION WAS LOW.

 

THE AREA OF LOW PRESSURE OVER THE NORTHERN PART OF THE
SOUTH CHINA SEA IS MOVING WESTWARDS STEADILY AND EDGING
CLOSER TO THE VICINITY OF HAINAN ISLAND. ITS STRUCTURE
REMAINS RELATIVELY LOOSE AND IT HAS NOT YET DEVELOPED INTO
A TROPICAL CYCLONE. ACCORDING TO THE PRESENT FORECAST, THE
AREA OF LOW PRESSURE WILL CONTINUE TO DEPART FROM HONG KONG
AND MOVE ACROSS HAINAN ISLAND TOMORROW (20 AUGUST). UNDER
THE COMBINED EFFECT OF THE RIDGE OF HIGH PRESSURE OVER THE
COAST OF SOUTHEASTERN CHINA AND THE AREA OF LOW PRESSURE,
IT WILL BE WINDIER WITH SHOWERS OVER THE COAST OF
GUANGDONG. 
 
THERE ARE RELATIVELY LARGE UNCERTAINTIES IN THE MOVEMENT OF
THE AREA OF LOW PRESSURE AFTER MOVING ACROSS HAINAN ISLAND.
IT MAY MOVE NORTHWARDS EDGING CLOSER TO THE VICINITY OF
BEIBU WAN TO LEIZHOU PENINSULA TOWARDS THE WEEKEND. THERE
IS ALSO A CHANCE OF RECURVING TO THE EAST AND EDGING CLOSER
TO THE COAST OF GUANGDONG. THE OBSERVATORY WILL CLOSELY
MONITOR ITS INTENSITY AND MOVEMENT, AND ASSESS THE NEED FOR
ISSUING THE STANDBY SIGNAL, NO. 1 BY THEN. MEMBERS OF THE
PUBLIC SHOULD TAKE NOTE OF THE LATEST WEATHER INFORMATION
ISSUED BY THE OBSERVATORY.

 

PLEASE BE REMINDED THAT:

 

THE STRONG MONSOON SIGNAL HAS BEEN ISSUED.
