ACCORDING TO THE PRESENT FORECAST, SUPER TYPHOON RAGASA

MOVING ACROSS THE VICINITY OF LUZON STRAIT AND ENTERING THE
NORTHERN PART OF THE SOUTH CHINA SEA, EDGING CLOSER TO THE
COAST OF GUANGDONG. ALTHOUGH LOCAL WEATHER WILL IMPROVE
BRIEFLY AND WILL BE VERY HOT ON MONDAY, THERE WILL BE
SWELLS. THE WEATHER WILL DETERIORATE LATER ON TUESDAY. GALE
TO STORM FORCE WINDS WILL PREVAIL ON WEDNESDAY, AND WINDS
MAY REACH HURRICANE FORCE OFFSHORE AND ON HIGH GROUND. THE
WEATHER WILL BE ADVERSE WITH HEAVY SQUALLY SHOWERS AND
THUNDERSTORMS. SEAS WILL BE VERY HIGH WITH SWELLS. UNDER
THE INFLUENCE OF SIGNIFICANT STORM SURGE, THE SEA LEVEL
OVER COASTAL AREAS BY THEN MAY BE SIMILAR TO THAT OF HATO
IN 2017 AND MANGKHUT IN 2018. MEMBERS OF THE PUBLIC PLEASE
TAKE NOTE OF THE LATEST WEATHER INFORMATION FROM THE
