***************************************

HOURLY READINGS

 

AT 4 P.M. AT THE HONG KONG OBSERVATORY THE AIR TEMPERATURE
WAS 27 DEGREES CELSIUS AND THE RELATIVE HUMIDITY 89 PER
CENT.
DURING THE PAST HOUR THE MEAN UV INDEX RECORDED AT KING'S
PARK WAS 0.2. THE INTENSITY OF UV RADIATION WAS LOW.

 

ACCORDING TO THE PRESENT FORECAST, WIPHA WILL ENTER WITHIN
800 KILOMETRES OF HONG KONG AROUND MIDNIGHT TONIGHT. 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 TOMORROW
AND ON SUNDAY (19 AND 20 JULY). WINDS WILL STRENGTHEN
GRADUALLY LATER TOMORROW. SHOWERS WILL BE HEAVY WITH
SQUALLY THUNDERSTORMS. THE OBSERVATORY WILL CONSIDER
ISSUING THE STRONG WIND SIGNAL, NO. 3 DURING THE DAY
TOMORROW. 
 
WIPHA WILL BE RATHER CLOSE TO THE VICINITY OF THE PEARL
RIVER ESTUARY ON SUNDAY (20 JULY), AND EXPECTED TO SKIRT
AROUND 50 KILOMETERS FROM HONG KONG. THE WEATHER WILL BE
ADVERSE ON SUNDAY WITH HEAVY SQUALLY SHOWERS AND
THUNDERSTORMS. 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. 
 
DEPENDING ON THE DISTANCE BETWEEN WIPHA AND THE PEARL RIVER
ESTUARY, THE INTENSITY OF WIPHA AND THE CHANGE IN LOCAL
WINDS, THE OBSERVATORY WILL ASSESS THE NEED OF ISSUING
HIGHER TROPICAL CYCLONE WARNING SIGNALS AT FIRST ON SUNDAY.
MEMBERS OF THE PUBLIC SHOULD PAY CLOSE ATTENTION TO THE
LATEST WEATHER INFORMATION FROM THE OBSERVATORY.
