TROPICAL CYCLONE WARNING BULLETIN (SIGNAL NO. 1)


 

TROPICAL CYCLONE WARNING BULLETIN
 
HERE IS THE LATEST TROPICAL CYCLONE WARNING BULLETIN ISSUED
BY THE HONG KONG OBSERVATORY.
 
THE STANDBY SIGNAL, NO. 1 IS IN FORCE.
 
THIS MEANS THAT A TROPICAL CYCLONE NOW CENTRED WITHIN ABOUT
800 KILOMETRES OF HONG KONG MAY AFFECT US.
 
AT 2 P.M., THE TROPICAL DEPRESSION OVER THE NORTHEASTERN
PART OF THE SOUTH CHINA SEA WAS ESTIMATED TO BE ABOUT 460
KILOMETRES EAST-SOUTHEAST OF HONG KONG (NEAR 20.1 DEGREES
NORTH 117.9 DEGREES EAST) AND IS FORECAST TO MOVE NORTHWEST
AT ABOUT 18 KILOMETRES PER HOUR IN THE GENERAL DIRECTION OF
THE COAST OF EASTERN GUANGDONG.

 

IN THE PAST FEW HOURS, THE TROPICAL CYCLONE CONTINUED TO
MOVE ACROSS THE NORTHEASTERN PART OF THE SOUTH CHINA SEA.
THE CIRCULATION OF THE TROPICAL CYCLONE IS RELATIVELY SMALL
AND IT WILL MAINTAIN A DISTANCE OF ABOUT 300 KILOMETRES OR
MORE FROM HONG KONG FOR MOST OF THE TIME TODAY. THE STANDBY
SIGNAL, NO. 1 WILL REMAIN IN FORCE TODAY. 
 
ACCORDING TO THE PRESENT FORECAST, THE TROPICAL CYCLONE
WILL INTENSIFY GRADUALLY WHILE EDGING CLOSER TO THE COAST
OF EASTERN GUANGDONG TODAY AND TOMORROW. UNDER THE
INFLUENCE OF THE NORTHEAST MONSOON, IT WILL THEN TURN
WESTWARDS, MOVING CLOSER TO THE VICINITY OF THE PEARL RIVER
ESTUARY. HOWEVER, THERE ARE UNCERTAINTIES IN ITS LANDFALL
POSITION AND INTENSITY. DEPENDING ON THE INTENSITY OF THE
TROPICAL CYCLONE, THE DISTANCE OF ITS STRONG WINDS FROM
HONG KONG AND THE CHANGE IN LOCAL WIND CONDITIONS, THE
OBSERVATORY WILL ASSESS THE NEED OF ISSUING HIGHER TROPICAL
CYCLONE WARNING SIGNALS TOMORROW. 
 
THE OUTER RAINBANDS OF THE TROPICAL CYCLONE ARE AFFECTING
THE COAST OF GUANGDONG. AS THE TROPICAL CYCLONE FURTHER
APPROACHES, LOCAL WINDS WILL STRENGTHEN AND SHOWERS WILL
INCREASE GRADUALLY TOMORROW. THERE WILL BE OCCASIONAL
SQUALLY SHOWERS AND THUNDERSTORMS ON SATURDAY. SHOWERS WILL
BE HEAVY AT TIMES. THERE WILL BE SWELLS. MEMBERS OF THE
PUBLIC ARE ADVISED TO STAY AWAY FROM THE SHORELINE AND NOT
TO ENGAGE IN WATER SPORTS.

1. PRECAUTIONS SHOULD BE TAKEN. DRAINS SHOULD BE CLEARED OF
OBSTRUCTIONS, AND WINDOWS AND DOORS SHOULD BE CHECKED.
 
2. PEOPLE IN AREAS OF EXPOSED TO HIGH WINDS OR IN LOW-LYING
