HOURLY READINGS


 

AT 9 A.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 30 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 72 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 2. THE INTENSITY OF UV RADIATION WAS LOW.

 

THE AREA OF LOW PRESSURE OVER THE NORTHEASTERN PART OF THE
SOUTH CHINA SEA HAS INTENSIFIED INTO A TROPICAL DEPRESSION.
THE OBSERVATORY WILL ISSUE THE STANDBY SIGNAL, NO. 1 AT
12:20 P.M. TODAY. ACCORDING TO THE PRESENT FORECAST, THE
CIRCULATION OF THE TROPICAL DEPRESSION WILL BE RELATIVELY
SMALL. IT WILL BE SLOW-MOVING AND MAINTAIN A DISTANCE OF
OVER 400 KILOMETRES FROM HONG KONG FOR THE REST OF TODAY.
THE STANDBY SIGNAL, NO. 1 WILL REMAIN IN FORCE FOR MOST OF
TODAY. THE TROPICAL CYCLONE IS EXPECTED TO INTENSIFY
GRADUALLY. IT IS MORE LIKELY TO LINGER OVER THE
NORTHEASTERN PART OF THE SOUTH CHINA SEA OVER THE WEEKEND
AND TURN NORTHWARDS IN THE GENERAL DIRECTION OF THE
VICINITY OF TAIWAN STRAIT TO THE COAST OF EASTERN
GUANGDONG. HOWEVER, THERE ARE STILL UNCERTAINTIES IN ITS
MOVEMENT. DEPENDING ON THE DISTANCE BETWEEN THE ASSOCIATED
STRONG WINDS AND THE PEARL RIVER ESTUARY AS WELL AS ITS
INTENSIFICATION, THE OBSERVATORY WILL ASSESS THE NEED OF
ISSUING HIGHER TROPICAL CYCLONE WARNING SIGNALS. LOCALLY,
THERE WILL BE SWELLS IN THE NEXT COUPLE OF DAYS. MEMBERS OF
THE PUBLIC SHOULD STAY AWAY FROM THE SHORELINE AND NOT
ENGAGE IN WATER SPORTS, AND TAKE NOTE OF THE LATEST WEATHER
INFORMATION 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.
