GENERAL SITUATION:
A BROAD TROUGH OF LOW PRESSURE WILL AFFECT THE NORTHERN
PART OF THE SOUTH CHINA SEA TO THE SEAS EAST OF LUZON IN
THE NEXT FEW DAYS. THERE ARE TWO AREAS OF LOW PRESSURE OVER
THE TROUGH OF LOW PRESSURE. HOWEVER, THERE ARE
UNCERTAINTIES IN THEIR SUBSEQUENT DEVELOPMENTS AND
MOVEMENTS. THE AREA OF LOW PRESSURE OVER THE NORTHERN PART
OF THE SOUTH CHINA SEA IS EXPECTED TO DEVELOP SLIGHTLY, AND
HAS A HIGHER CHANCE TO MOVE TOWARDS THE VICINITY OF HAINAN
ISLAND TODAY AND TOMORROW. MEANWHILE, UNDER ITS COMBINED
EFFECT WITH A RIDGE OF HIGH PRESSURE OVER SOUTHEASTERN
CHINA, IT WILL BE WINDIER WITH SHOWERS OVER THE COAST OF
GUANGDONG. BESIDES, THE AREA OF LOW PRESSURE TO THE EAST OF
LUZON WILL MOVE IN THE GENERAL DIRECTION OF THE VICINITY OF
TAIWAN. WITH THE WHOLE LOW PRESSURE SYSTEM EDGING CLOSER TO
THE VICINITY OF THE COAST OF SOUTHEASTERN CHINA TO SOUTHERN
CHINA, THE WEATHER OVER THE REGION WILL BE UNSETTLED IN THE
LATTER PART OF THIS WEEK.
