HOURLY READINGS


 

AT 4 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 32 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 66 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 5. THE INTENSITY OF UV RADIATION WAS MODERATE.

 

THE BROAD AREA OF LOW PRESSURE TO THE WEST OF LUZON HAS
ENTERED THE CENTRAL AND NORTHERN PARTS OF THE SOUTH CHINA
SEA AND IS DEVELOPING GRADUALLY, BUT ITS STRUCTURE IS STILL
LOOSE. IF THE BROAD AREA OF LOW PRESSURE FURTHER DEVELOPS
INTO A TROPICAL CYCLONE TONIGHT TO TOMORROW MORNING, THE
OBSERVATORY WILL CONSIDER ISSUING THE STANDBY SIGNAL, NO. 1
BY THEN. THE LOW PRESSURE SYSTEM WILL MOVE TOWARDS HAINAN
ISLAND AND THE SEAS SOUTH OF IT. HOWEVER, THERE ARE
UNCERTAINTIES IN ITS INTENSITY. UNDER THE COMBINED EFFECT
OF THE LOW PRESSURE SYSTEM AND THE RIDGE OF HIGH PRESSURE
OVER SOUTHEASTERN CHINA, IT WILL BE WINDY WITH SHOWERS,
THUNDERSTORMS AND SQUALLS OVER THE NORTHERN PART OF THE
SOUTH CHINA SEA AND THE COAST OF SOUTHERN CHINA TOMORROW
AND ON FRIDAY (28 AND 29 AUGUST). THERE WILL BE SWELLS.
UNLESS THE LOW PRESSURE SYSTEM INTENSIFIES SIGNIFICANTLY,
OR DEVELOP CLOSER TO THE COAST OF GUANGDONG, OR ADOPTS A
TRACK CLOSER TO THE COAST OF GUANGDONG, THE CHANCE OF
PERSISTENT STRONG WINDS GENERALLY OVER THE TERRITORY IS
EXPECTED TO BE RELATIVELY LOW. MEMBERS OF THE PUBLIC SHOULD
TAKE NOTE OF THE LATEST WEATHER INFORMATION FROM THE
OBSERVATORY, STAY AWAY FROM THE SHORELINE AND NOT TO ENGAGE
IN WATER SPORTS.

 

PLEASE BE REMINDED THAT:

 

THE THUNDERSTORM WARNING HAS BEEN ISSUED. IT WILL REMAIN
EFFECTIVE UNTIL 5:00 P.M. TODAY. ISOLATED THUNDERSTORMS ARE
EXPECTED TO OCCUR OVER NEW TERRITORIES WEST.
THE VERY HOT WEATHER WARNING IS NOW IN FORCE. THE PUBLIC
SHOULD BEWARE OF HEAT STROKE AND DRINK MORE WATER.
