BECAUSE OF FOGGY CONDITIONS. MANY HONG KONG-MACAU FERRIES WERE EITHER DELAYED OR CANCELLED. THREE OUTGOING FLIGHTS WERE ALSO DELAYED.
THE APPROACH OF A TROUGH OF LOW PRESSURE FROM THE NORTH BROUGHT OVERCAST SKIES AND LIGHT RAIN ON JANUARY 9. THESE CONDITIONS PREVAILED UNTIL JANUARY 11 WHEN THE SKY GRADUALLY CLEARED.
HOWEVER, RAINY WEATHER RETURNED EARLY ON JANUARY 12 AS A COLD FRONT REACHED THE SOUTH CHINA COAST. THE INTRUSION OF COLD AIR FROM THE NORTH COUPLED WITH OCCASIONAL LIGHT RAIN RESULTED IN TEMPERATURES FALLING CONTINUOUSLY FOR THE NEXT TWO DAYS.
BY THE MORNING OF JANUARY 14, THE TEMPERATURE HAD FALLEN TO A MINIMUM OF 7.6 DEGREES WHICH WAS THE LOWEST FOR THE MONTH. TEMPERATURES OVER THE NEW TERRITORIES WERE EVEN LOWER.
COLD AND CLOUDY WEATHER LASTED UNTIL JANUARY 17 WHEN THE WINDS TURNED EASTERLY. THE SKY THEN CLEARED DURING THE DAY BUT BECAME CLOUDY WITH SOME LIGHT RAIN PATCHES AT NIGHT. THESE ALTERNATE FINE AND CLOUDY CONDITIONS CONTINUED FOR THE NEXT TWO DAYS.
FRESHENING OF WINDS FROM THE EAST EARLY ON JANUARY 21 BROUGHT
BACK OVERCAST AND RAINY WEATHER.
THEN A SURGE OF THE WINTER MONSOON FROM THE NORTH IN THE AFTERNOON OF JANUARY 22 BROUGHT COLD AND MUCH DRIER AIR TO SOUTH CHINA AND THE SKY TURNED CLEAR.
FINE WEATHER PERSISTED UNTIL JANUARY 24 WHEN A SLIGHT STRENGTHENING OF THE EASTERLIES BROUGHT GENERALLY CLOUDY CONDITIONS TO THE TERRITORY, OCCASIONAL LIGHT RAIN ALSO OCCURRED DURING THE NEXT TWO DAYS.
OVERNIGHT ON JANUARY 26, A SURGE OF THE WINTER MONSOON REACHED THE SOUTH CHINA COAST AND RAIN BECAME HEAVIER.
THE OVERCAST AND RAINY CONDITIONS CONTINUED UNTIL JANUARY 30 WHEN THE RAIN STOPPED. SOME BRIEF INTERVALS OF SUNSHINE ALS OCCURRED DURING THE DAY ON JANUARY 31.
ONLY ONE TROPICAL CYCLONE DEVELOPED OVER THE WESTERN PACIFIC IN JANUARY, AN AREA OF LOW PRESSURE WHICH ORIGINATED THE INTERNATIONAL DATELINE MOVED WEST-SOUTHWESTWARDS INTO THE NORTH PACIFIC ON JANUARY 15.
