HOWEVER, THE STRONG MONSOON SIGNAL HAD TO BE HOISTED TWICE ON NOVEMBER 18 DUE TO THE STRONG NORTHERLIES. THE FREQUENT SURGES OF THE WINTER MONSOON SINCE NOVEMBER 7 GAVE RISE TO PROGRESSIVELY COOLER CONDITIONS OVERNIGHT WITH THE DAILY MINIMUM TEMPERATURES REGISTERING A GENERALLY DOWNWARD TREND DURING THIS PERIOD.

MEANWHILE, TYPHOON HUNT WEAKENED AS IT SWEPT ACROSS THE PULIPPINES ON NOVEMBER 22 AND DISSIPATED OVER THE SOUTH CHINA SEA DURING THE NEXT 24 HOURS. FOR DAYS, THE BAND OF CLOUDS BROUGHT

IN BY HUNT LINGERED OVER THE SOUTH CHINA COASTAL WATERS.

BEING ON THE FRINGE OF THIS CLOUD BAND, LOCAL WEATHER TURNED CLOUDY ON NOVEMBER 22. THE RAIN AREA WITHIN THE CLOUD BAND EVENTUALLY MOVED IN ON NOVEMBER 25 AS THE REMNANT OF HUNT DRIFTED TOWARDS THE VIETNAM COAST.

COUPLED WITH THE FRESHENING OF THE EASTERLIES EARLY ON NOVEMBER 26, THE WEATHER KEMAINED CLOUDY WITH INTERMITTENT LIGHT RAIN UNTIL NOVEMBER 27.

LATER IN THE EVENING ON NOVEMBER 27, AN INTENSE SURGE OF THE WINTER MONSOON REACHED THE COASTAL AREAS AND NECESSITATED THE HOISTING OF THE STRONG MONSOON SIGNAL FOR THE FOURTH TIME IN THE MONTH. THE ARRIVAL OF COLD AND DRY CONTINENTAL AIR RESULTED IN A CLEARANCE OF CLOUDS AND A MARKED DROP IN TEMPERATURE.
