AN AREA OF LOW PRESSURE IS MOVING ACROSS THE VICINITY OF
THE PEARL RIVER ESTUARY. ITS INTENSE RAIN BAND IS AFFECTING
HONG KONG. WHETHER THE RED RAINSTORM WARNING SIGNAL NEEDS
TO BE ISSUED DEPENDS ON THE DEVELOPMENT OF THE AREAS OF THE
RAIN BAND. MEMBERS OF THE PUBLIC SHOULD BE ON THE ALERT AND
TAKE NOTE OF THE LATEST WEATHER INFORMATION.
  
A BROAD TROUGH OF LOW PRESSURE OVER THE NORTHERN PART OF
THE SOUTH CHINA SEA IS BRINGING SHOWERS AND THUNDERSTORMS
TO THE COAST OF GUANGDONG, AND THERE IS AN AREA OF LOW
PRESSURE LOCATED AT ABOUT 40 KILOMETRES EAST-NORTHEAST OF
THE HONG KONG OBSERVATORY OVER THE TROUGH OF LOW PRESSURE.
ITS WIND STRENGTH AND CONVECTIONS NEAR THE CENTRE ARE
RELATIVELY WEAK. IT HAS NOT YET REACHED THE INTENSITY OF A
TROPICAL CYCLONE. IT IS FORECAST TO MOVE WESTWARDS IN THE
GENERAL DIRECTION OF THE VICINITY OF THE PEARL RIVER
ESTUARY TO THE COAST OF WESTERN GUANGDONG. WHEN THE AREA OF
LOW PRESSURE EDGES CLOSER TO HONG KONG, LOCAL WINDS IN SOME
AREAS MAY PICK UP WITH SQUALLY THUNDERSTORMS. THE
OBSERVATORY WILL CLOSELY MONITOR ITS DEVELOPMENT AND
MOVEMENT. MEMBERS OF THE PUBLIC PLEASE BE AWARE OF THE
CHANGE IN WEATHER.
