9-DAY WEATHER FORECAST
 
GENERAL SITUATION:
TROPICAL CYCLONE RAGASA WILL MOVE ACROSS THE NORTHERN PART
OF THE SOUTH CHINA SEA, GRADUALLY EDGING CLOSER TO THE
COAST OF GUANGDONG TODAY. UNDER THE INFLUENCE OF ITS
EXTENSIVE CIRCULATION, THE WEATHER OVER THE COASTAL AREAS
WILL DETERIORATE RAPIDLY WITH WINDS STRENGTHENING
SIGNIFICANTLY LATER TODAY. THERE WILL BE FREQUENT HEAVY
SQUALLY SHOWERS, THUNDERSTORMS AND SIGNIFICANT STORM SURGE
TOMORROW. SEAS WILL BE VERY HIGH WITH SWELLS. WITH THE
DEPARTURE OF RAGASA, SHOWERS WILL EASE OFF GRADUALLY AND
THE WEATHER WILL IMPROVE IN THE LATTER PART OF THIS WEEK.
BESIDES, A BROAD AREA OF LOW PRESSURE OVER THE WESTERN
NORTH PACIFIC WILL DEVELOP GRADUALLY IN THE NEXT COUPLE OF
DAYS. IT WILL MOVE ACROSS THE PHILIPPINES AND ENTER THE
SOUTH CHINA SEA, POSSIBLY BRINGING UNSETTLED WEATHER TO THE
CENTRAL AND NORTHERN PARTS OF THE SOUTH CHINA SEA OVER THE
WEEKEND. HOWEVER, THERE ARE STILL UNCERTAINTIES IN ITS
DEVELOPMENT AND MOVEMENT.
