HOURLY READINGS


 

AT 2 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 27 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 90 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 0.1. THE INTENSITY OF UV RADIATION WAS LOW.

 

ACCORDING TO THE PRESENT FORECAST, WIPHA WILL ENTER WITHIN
800 KILOMETRES OF HONG KONG TONIGHT TO EARLY TOMORROW (19
JULY). THE OBSERVATORY WILL ISSUE THE STANDBY SIGNAL, NO. 1
BY THEN. WIPHA IS EXPECTED TO INTENSIFY PROGRESSIVELY AND
EDGE CLOSER TO THE VICINITY OF THE PEARL RIVER ESTUARY AND
THE COAST OF WESTERN GUANGDONG AFTERWARDS. UNDER THE
INFLUENCE OF ITS OUTER SUBSIDING AIR, THE WEATHER WILL
STILL BE VERY HOT IN HONG KONG AT FIRST TOMORROW. WINDS
WILL STRENGTHEN GRADUALLY LATER TOMORROW. THE WEATHER WILL
WORSEN WITH HEAVY SQUALLY SHOWERS AND THUNDERSTORMS ON
SUNDAY. SEAS WILL BE VERY ROUGH WITH SWELLS. MEMBERS OF THE
PUBLIC ARE ADVISED TO STAY AWAY FROM THE SHORELINE AND NOT
TO ENGAGE IN WATER SPORTS. THE OBSERVATORY WILL CONSIDER
ISSUING THE STRONG WIND SIGNAL, NO. 3 DURING THE DAY
TOMORROW.
 
WIPHA WILL BE CLOSEST TO THE VICINITY OF THE PEARL RIVER
ESTUARY ON SUNDAY. THE OBSERVATORY WILL ASSESS THE NEED OF
ISSUING HIGHER TROPICAL CYCLONE WARNING SIGNALS AT THAT
TIME DEPENDING ON WIPHA’S DISTANCE TO THE PEARL RIVER
ESTUARY, ITS INTENSITY AND THE CHANGE IN LOCAL WINDS.
MEMBERS OF THE PUBLIC SHOULD PAY CLOSE ATTENTION TO THE
LATEST WEATHER INFORMATION FROM THE OBSERVATORY.

THOUGH RAINSTORM WARNING HAS BEEN CANCELLED, PEOPLE SHOULD
STAY ALERT TO THE DANGER THAT MAY BE BROUGHT ABOUT BY RIVER
FLOODING.

 

PLEASE BE REMINDED THAT:

 

THE THUNDERSTORM WARNING HAS BEEN ISSUED. IT WILL REMAIN
EFFECTIVE UNTIL 5:00 P.M. TODAY. A FEW THUNDERSTORMS ARE
EXPECTED TO OCCUR OVER HONG KONG.
THE SPECIAL ANNOUNCEMENT OF FLOODING IN NORTHERN NEW
