HOURLY READINGS


 

AT 1 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 33 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 70 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 8. THE INTENSITY OF UV RADIATION WAS VERY HIGH.

 

AN AREA OF LOW PRESSURE WITHIN THE BROAD TROUGH OF LOW
PRESSURE OVER THE NORTHERN PART OF THE SOUTH CHINA SEA WILL
DEVELOP GRADUALLY AND EDGE CLOSER TO THE COAST OF
GUANGDONG. SINCE THE CONVECTIVE CLOUDS ASSOCIATED WITH IT
ARE MAINLY LOCATED AT ITS SOUTHERN SIDE CURRENTLY, IT IS
EXPECTED TO TAKE SOME TIME TO CONSOLIDATE. WHETHER IT WILL
DEVELOP INTO A TROPICAL DEPRESSION CAN ONLY BECOME MORE
CERTAIN WHEN IT IS RELATIVELY CLOSE TO THE COAST OF
GUANGDONG. IF THE AREA OF LOW PRESSURE DEVELOPS INTO A
TROPICAL DEPRESSION, THE OBSERVATORY WILL ASSESS THE NEED
FOR ISSUING THE STANDBY SIGNAL, NO. 1 THIS EVENING (13
JULY) TO TOMORROW MORNING (14 JULY).
 
ACCORDING TO THE PRESENT FORECAST, THE LOW PRESSURE SYSTEM
WILL BE CLOSEST TO HONG KONG TOMORROW MORNING, SKIRTING
WITHIN 100 KILOMETRES OF THE TERRITORY. HEAVY SHOWERS,
THUNDERSTORMS AND SQUALLS WILL AFFECT HONG KONG TOMORROW.
THERE MAY BE A NEED TO ISSUE RAINSTORM WARNING SIGNALS OR
LOCALISED HEAVY RAIN ADVISORY. STRONG WINDS WILL PREVAIL
OFFSHORE. FLOODING MAY OCCUR IN SOME LOW-LYING AREAS.
SHOWERS WILL BE HEAVY AT TIMES AT FIRST ON WEDNESDAY (15
JULY) AND THERE WILL STILL BE STRONG WINDS OFFSHORE. THE
OBSERVATORY WILL CLOSELY MONITOR THE DEVELOPMENT AND
MOVEMENT OF THE LOW PRESSURE SYSTEM. MEMBERS OF THE PUBLIC
SHOULD 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.
