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 NOON, THE TROPICAL DEPRESSION OVER THE NORTHEASTERN PART
OF THE SOUTH CHINA SEA WAS ESTIMATED TO BE ABOUT 500
KILOMETRES EAST-SOUTHEAST OF HONG KONG (NEAR 20.0 DEGREES
NORTH 118.3 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.
 
LOCALLY, THE WEATHER IS EXPECTED TO REMAIN VERY HOT THIS
AFTERNOON. WINDS WILL STRENGTHEN WITH MORE SHOWERS
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.

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