9-DAY WEATHER FORECAST


9-DAY WEATHER FORECAST
 
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. TWO AREAS OF LOW PRESSURE MAY EXIST 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 IN THE NEXT COUPLE OF DAYS. UNDER THE COMBINED
EFFECT OF THE AREA OF LOW PRESSURE AND A RIDGE OF HIGH
PRESSURE OVER SOUTHEASTERN CHINA, IT WILL BE WINDIER WITH
SHOWERS OVER THE COAST OF GUANGDONG MIDWEEK THIS WEEK.
MEANWHILE, THE AREA OF LOW PRESSURE TO THE EAST OF LUZON
WILL GENERALLY MOVE TOWARDS 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.
