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 A.M., SEVERE TROPICAL STORM MATMO WAS ESTIMATED TO BE
ABOUT 640 KILOMETRES SOUTHEAST OF HONG KONG (NEAR 17.7
DEGREES NORTH 117.9 DEGREES EAST) AND IS FORECAST TO MOVE
WEST-NORTHWEST AT ABOUT 25 KILOMETRES PER HOUR ACROSS THE
CENTRAL AND NORTHERN PARTS OF THE SOUTH CHINA SEA AND
INTENSIFY GRADUALLY.

 

MATMO IS EXPECTED TO MAINTAIN A DISTANCE OF ABOUT 500
KILOMETRES OR MORE FROM HONG KONG ON SATURDAY MORNING (4
OCTOBER). THE STANDBY SIGNAL, NO. 1 WILL REMAIN IN FORCE
UNTIL NOON ON SATURDAY.
 
ACCORDING TO THE PRESENT FORECAST, MATMO WILL INTENSIFY
PROGRESSIVELY AND EDGE CLOSER TO THE VICINITY OF LEIZHOU
PENINSULA AND THE EASTERN PART OF HAINAN ISLAND. LOCAL
WINDS WILL STRENGTHEN GRADUALLY LATER ON SATURDAY. THE
OBSERVATORY WILL CONSIDER ISSUING THE STRONG WIND SIGNAL,
NO. 3 IN THE EARLY AFTERNOON ON SATURDAY. DEPENDING ON THE
INTENSITY OF MATMO, THE DISTANCE OF ITS ASSOCIATED GALE
FORCE WINDS FROM THE PEARL RIVER ESTUARY AND THE CHANGE IN
LOCAL WIND CONDITIONS, THE OBSERVATORY WILL THEN ASSESS THE
NEED OF ISSUING HIGHER TROPICAL CYCLONE WARNING SIGNALS.
 
LOCALLY, IT WILL STILL BE VERY HOT DURING THE DAY ON
SATURDAY. UNDER THE INFLUENCE OF THE OUTER RAINBANDS OF
MATMO, THERE WILL BE A FEW SQUALLY SHOWERS AND
THUNDERSTORMS LATER ON SATURDAY AND MORE SHOWERS AT FIRST
ON SUNDAY (5 OCTOBER). SEAS WILL BE ROUGH WITH SWELLS.
MEMBERS OF THE PUBLIC ARE ADVISED TO STAY AWAY FROM THE
SHORELINE AND NOT TO ENGAGE IN WATER SPORTS.
