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., THE TROPICAL DEPRESSION OVER THE NORTHEASTERN
PART OF THE SOUTH CHINA SEA WAS ESTIMATED TO BE ABOUT 690
KILOMETRES EAST-SOUTHEAST OF HONG KONG (NEAR 19.0 DEGREES
NORTH 119.8 DEGREES EAST) AND IS FORECAST TO MOVE NORTHWEST
AT ABOUT 18 KILOMETRES PER HOUR IN THE GENERAL DIRECTION OF
THE COAST OF EASTERN GUANGDONG.

 

THE TROPICAL CYCLONE WILL MOVE ACROSS THE NORTHEASTERN PART
OF THE SOUTH CHINA SEA AND INTENSIFY GRADUALLY TODAY AND
TOMORROW (18 AND 19 SEPTEMBER). THE TROPICAL CYCLONE HAS A
RELATIVELY SMALL CIRCULATION, AND WILL MAINTAIN A DISTANCE
OF OVER 400 KILOMETRES FROM HONG KONG THIS MORNING. THE
STANDBY SIGNAL, NO. 1 WILL REMAIN IN FORCE BEFORE NOON
TODAY.
 
ACCORDING TO THE PRESENT FORECAST, THE TROPICAL CYCLONE
WILL EDGE CLOSER TO THE COAST OF EASTERN GUANGDONG
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 TO ISSUE
HIGHER TROPICAL CYCLONE WARNING SIGNALS LATER TODAY TO
TOMORROW.
 
THE LOCAL WEATHER IS EXPECTED TO REMAIN VERY HOT TODAY.
THERE WILL BE MORE SHOWERS AND WINDS WILL STRENGTHEN
GRADUALLY LATER TOMORROW. THERE WILL BE OCCASIONAL SQUALLY
SHOWERS AND THUNDERSTORMS OVER THE WEEKEND. SHOWERS WILL BE
HEAVIER AT TIMES, AND THERE WILL BE SWELLS.

1. PRECAUTIONS SHOULD BE TAKEN. DRAINS SHOULD BE CLEARED OF
OBSTRUCTIONS, AND WINDOWS AND DOORS SHOULD BE CHECKED.
