TROPICAL CYCLONE WARNING BULLETIN
 
HERE IS THE LATEST TROPICAL CYCLONE WARNING BULLETIN ISSUED
BY THE HONG KONG OBSERVATORY.
 
THE STANDBY SIGNAL, NO. 1 WAS ISSUED AT 12:20 P.M.
 
THIS MEANS THAT A TROPICAL CYCLONE WILL COME WITHIN 800
KILOMETRES OF HONG KONG AND MAY AFFECT US.
 
AT NOON, SUPER TYPHOON RAGASA WAS ESTIMATED TO BE ABOUT 890
KILOMETRES EAST-SOUTHEAST OF HONG KONG (NEAR 19.4 DEGREES
NORTH 122.1 DEGREES EAST) AND IS FORECAST TO MOVE WEST OR
WEST-NORTHWEST AT ABOUT 22 KILOMETRES PER HOUR ACROSS THE
LUZON STRAIT AND ENTER THE NORTHERN PART OF THE SOUTH CHINA
SEA.

 

ACCORDING TO THE PRESENT FORECAST, RAGASA WILL MOVE ACROSS
THE LUZON STRAIT AND ENTER THE NORTHERN PART OF THE SOUTH
CHINA SEA TODAY. WITH RAGASA EDGING CLOSER TO THE COAST OF
GUANGDONG, LOCAL WINDS WILL STRENGTHEN GRADUALLY. THE
OBSERVATORY WILL ISSUE THE STRONG WIND SIGNAL, NO. 3 AT
9:40 P.M. TONIGHT. 
 
THE LOCAL WEATHER IS EXPECTED TO DETERIORATE RAPIDLY LATER
TOMORROW (23 SEPTEMBER). THE OBSERVATORY WILL CONSIDER
ISSUING THE GALE OR STORM SIGNAL, NO. 8 BETWEEN 1 P.M. AND

SQUALLY SHOWERS AND THUNDERSTORMS. SEAS WILL BE VERY HIGH
WITH SWELLS. MEMBERS OF THE PUBLIC ARE ADVISED TO STAY AWAY
