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 10 P.M., THE TROPICAL DEPRESSION NEAR LUZON WAS
ESTIMATED TO BE ABOUT 760 KILOMETRES SOUTHEAST OF HONG KONG
(NEAR 18.4 DEGREES NORTH 120.1 DEGREES EAST) AND IS
FORECAST TO MOVE NORTHWEST AT ABOUT 18 KILOMETRES PER HOUR
CROSSING THE NORTHEASTERN PART OF THE SOUTH CHINA SEA.

 

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

 

(PRECAUTIONARY ANNOUNCEMENTS WITH NO. 1 SIGNAL)
 
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
AREAS SHOULD TAKE PRECAUTIONS AGAINST STRONG WINDS AND
FLOODING.
 
3. THOSE WHO HAVE DUTIES DURING A TROPICAL CYCLONE SHOULD
NOW REMAIN ON CALL.
 
4. PEOPLE PLANNING TO VISIT GUANGDONG, MACAU, OUTLYING
ISLANDS OR REMOTE PARTS OF HONG KONG SHOULD NOTE THAT
CHANGES IN WEATHER MAY AFFECT YOUR TRIPS.
 
5. FISHING VESSELS AND LOW POWER VESSELS IN OPEN SEA SHOULD
