The Observatory predicts that there will be 4 to 7 tropical cyclones affecting Hong Kong this year. There have been 5 of them so far. The wind season seems to be unfinished.
Typhoon "Molafi" traversed central Vietnam today (28th). The Observatory predicted that an area of low pressure in the Northwest Pacific would gradually develop into a tropical cyclone in the next few days and move towards the Philippines.
With reference to European and American forecasting systems, one tropical cyclone will enter the South China Sea early next week or be upgraded to tropical storm level; another tropical cyclone is even stronger and will linger east of the Philippines later in the next week or reach super typhoon level.

With reference to the European Center for Medium-Range Weather Forecast (ECMWF), a tropical cyclone will enter the South China Sea next Monday (November 1), and then may intensify to tropical storm level, with the lowest central sea level pressure of 995 hPa, and then move towards Vietnam.
However, another tropical cyclone hovered east of the Philippines later in the next week. The lowest pressure at the center of the sea level was 931 hPa, which could reach the super typhoon level.
As for the Global Forecast System (GFS), it is predicted that the tropical cyclone can reach a strong typhoon level and will hit Kaohsiung, Taiwan next Friday (November 6).

The blue moon appears on Halloween, the minimum is 21 degrees in the city
Looking back at the weather in Hong Kong, a strong northeast monsoon is affecting Hong Kong, so today it is generally cloudy with a few rain patches. Later, the rain will be more frequent. The wind will be fresh from the east to the northeast, strong offshore winds, and occasionally highlands. Gale.

The minimum temperature in the urban area will further drop to 20 degrees.

The observatory expects to be cold this winter
In addition, the Observatory pointed out yesterday (27th) that in the past month or so, the water temperature in the central and eastern equatorial Pacific continued to drop, and by September the water temperature in this area was already below normal.
Based on the latest ocean observation data and forecasts from multiple climate models around the world, it is expected that the central and eastern parts of the equatorial Pacific will remain cold in the winter of 2020/21 (from December 2020 to February 2021), and may develop into one La Nina incident.
