HOURLY READINGS


 

AT 4 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 34 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 56 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 OVER THE CENTRAL PART OF THE
SOUTH CHINA SEA IS EXPECTED TO DEVELOP INTO A TROPICAL
CYCLONE GRADUALLY TODAY AND TOMORROW (9 AND 10 JUNE).
DEPENDING ON ITS RATE OF DEVELOPMENT AND THE TIME OF
ENTERING WITHIN 800 KILOMETRES OF HONG KONG, THE
OBSERVATORY WILL ISSUE THE STANDBY SIGNAL, NO. 1 BETWEEN
TUESDAY NIGHT (10 JUNE) AND EARLY WEDNESDAY (11 JUNE) THE
EARLIEST. THE TROPICAL CYCLONE IS EXPECTED TO MOVE IN THE
GENERAL DIRECTION OF THE VICINITY OF THE COAST OF WESTERN
GUANGDONG TO HAINAN ISLAND IN THE MIDDLE AND LATTER PARTS
OF THIS WEEK. DEPENDING ON ITS DISTANCE FROM HONG KONG AND
THE RATE OF DEVELOPMENT, THE OBSERVATORY WILL ASSESS THE
NEED OF ISSUING A HIGHER TROPICAL CYCLONE WARNING SIGNAL
LATER ON WEDNESDAY TO THURSDAY (12 JUNE). LOCALLY, VERY HOT
WEATHER WILL PERSIST IN THE NEXT COUPLE OF DAYS (10 AND 11
JUNE). HOWEVER, WITH THE TROPICAL CYCLONE EDGING CLOSER,
THE WEATHER WILL BE WINDY WITH OCCASIONAL SQUALLY SHOWERS
IN THE LATTER PART OF THIS WEEK, AND THERE WILL BE SWELLS.
SINCE THE CHANGE IN WEATHER WILL BE RATHER SUBSTANTIAL,
MEMBERS OF THE PUBLIC PLEASE PAY ATTENTION TO THE LATEST
WEATHER FORECAST FROM THE OBSERVATORY.

 

PLEASE BE REMINDED THAT:

 

THE VERY HOT WEATHER WARNING IS NOW IN FORCE. PROLONGED
HEAT ALERT! PLEASE DRINK SUFFICIENT WATER. IF FEELING
UNWELL, TAKE REST OR SEEK HELP IMMEDIATELY. IF NEEDED, SEEK
MEDICAL ADVICE AS SOON AS POSSIBLE.
