HOURLY READINGS


 

AT 2 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 35 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 49 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 9. THE INTENSITY OF UV RADIATION WAS VERY HIGH.

 

THE AREA OF LOW PRESSURE NEAR LUZON IS CURRENTLY ABOUT 800
KILOMETRES AWAY FROM HONG KONG. IT IS EXPECTED TO DEVELOP
INTO A TROPICAL CYCLONE TONIGHT (5 SEPTEMBER) TO TOMORROW
MORNING (6 SEPTEMBER). THE OBSERVATORY WILL CONSIDER
ISSUING THE STANDBY SIGNAL, NO. 1 BY THEN. UNDER THE
INFLUENCE OF AN ANTICYCLONE ALOFT, IT WILL STILL BE MAINLY
FINE IN HONG KONG TOMORROW. THE WEATHER WILL BE EXTREMELY
HOT DURING THE DAY, WITH TEMPERATURES REACHING ABOUT 35
DEGREES IN THE URBAN AREAS, AND A COUPLE OF DEGREES HIGHER
IN THE NEW TERRITORIES. ACCORDING TO THE PRESENT FORECAST,
THE TROPICAL CYCLONE WILL INTENSIFY PROGRESSIVELY AND MOVE
IN THE GENERAL DIRECTION OF THE COAST OF GUANGDONG IN THE
NEXT COUPLE OF DAYS, BUT THERE ARE UNCERTAINTIES IN ITS
INTENSITY AND SPEED OF MOVEMENT. UNDER ITS INFLUENCE, WINDS
ARE EXPECTED TO STRENGTHEN GRADUALLY IN HONG KONG ON SUNDAY
(7 SEPTEMBER), AND THE WEATHER WILL BECOME UNSETTLED. THE
WEATHER WILL BE WINDY WITH HEAVY SQUALLY SHOWERS AND
THUNDERSTORMS ON MONDAY (8 SEPTEMBER), AND SEAS WILL BE
ROUGH WITH SWELLS. DUE TO STORM SURGE, THERE MAY BE
FLOODING IN LOW-LYING COASTAL AREAS ON MONDAY MORNING.
DEPENDING ON THE INTENSITY OF THE TROPICAL CYCLONE, THE
DISTANCE OF ITS STRONG WINDS FROM THE TERRITORY AND THE
CHANGES IN LOCAL WINDS, THE OBSERVATORY WILL ASSESS THE
NEED OF ISSUING HIGHER TROPICAL CYCLONE WARNING SIGNALS ON
SUNDAY. MEMBERS OF THE PUBLIC SHOULD PAY ATTENTION TO THE
LATEST WEATHER INFORMATION FROM THE OBSERVATORY.

 

PLEASE BE REMINDED THAT:

 

THE VERY HOT WEATHER WARNING IS NOW IN FORCE. THE WEATHER
IS EXTREMELY HOT AND THERE IS PROLONGED HEAT! PLEASE PAY
ATTENTION TO HEALTH CONDITIONS. DRINK MORE WATER AND TAKE
ALL NECESSARY PROTECTIVE MEASURES AGAINST THE HEAT. AVOID
VIGOROUS OUTDOOR PHYSICAL ACTIVITIES. IF FEELING UNWELL,
SEEK MEDICAL ADVICE AS SOON AS POSSIBLE.
