2.1 Review of tropical cyclones in 2017

2.1.1 Tropical cyclones over the western North Pacific (including the South China Sea)

In 2017, a total of 32 tropical cyclones occurred over the western North Pacific (WNP) and the South China Sea (SCS) bounded by the Equator, 45°N, 100°E and 180°, slightly more than the long-term (1961 - 2010) average figure of around 30. During the year, 12 of the tropical cyclones attained typhoon intensity or above, less than the long-term average (1961 - 2010) of about 15, with four of them reaching super typhoon intensity (maximum 10-minute wind speed of 185 km/h or above near the centre).

Figure 2.1 shows the monthly frequencies of the occurrence of tropical cyclones in WNP and SCS in 2017.

During the year, nine tropical cyclones made landfall over China, with five of them crossing the south China coast within 300 km of Hong Kong and two crossed Taiwan. Four tropical cyclones made landfall over Japan, nine traversed the Philippines and seven made landfall over Vietnam. With an estimated maximum sustained wind speed of 205 km/h and a minimum sea-level pressure of 925 hPa near its centre (Table 4.1), Super Typhoon Lan (1721) in October (Figure 2.3) was the most intense tropical cyclone over the western North Pacific and the South China Sea in 2017.

2.1.2 Tropical cyclones in Hong Kong's area of responsibility

Amongst the 32 tropical cyclones in 2017, 22 of them occurred inside Hong Kong’s area of responsibility (i.e. the area bounded by 10°N, 30°N, 105°E and 125°E), more than the long-term annual average figure of around 16 ((Table 2.1). 13 of them developed within Hong Kong’s area of responsibility. Altogether, 427 tropical cyclone warnings to ships and vessels were issued by the Hong Kong Observatory in 2017 (Table 4.2).

2.1.3 Tropical cyclones over the South China Sea

18 tropical cyclones affected SCS bounded by 10°N, 25°N, 105°E and 120°E in 2017, more than the long-term annual average of around 12. Eight of them formed within SCS.

2.1.4 Tropical cyclones affecting Hong Kong

In 2017, the typhoon season in Hong Kong started on 11 June when tropical depression Merbok (1702) formed in the central part of the South China Sea and edged closer to the coast of Guangdong, necessitating the issuance of the Standby Signal No. 1. The typhoon season ended with the cancellation of all tropical cyclone warning signals on 16 October as Severe Tropical Storm Khanun (1720) moved towards Leizhou Peninsula and weakened that day.

Seven tropical cyclones affected Hong Kong during 2017 (Figure 2.2), slightly more than the long-term (1961-2010) average of about six in a year (Table 2.2). They were Severe Tropical Storm Merbok (1702) in June, Tropical Storm Roke (1707) in July, Super Typhoon Hato (1713) and Severe Tropical Storm Pakhar (1714) in August, Severe Tropical Storm Mawar (1716) and a Tropical Depression in September, and Severe Typhoon Khanun (1720) in October. The No.10 Hurricane Signal was issued by the Hong Kong Observatory during the passage of Hato on 23 August. It was the highest tropical cyclone warning signal issued in 2017 and for the first time since Severe Typhoon Vicente hitting Hong Kong in July 2012. The No. 8 Gale or Storm Signal was issued during the passage of Merbok, Roke, Pakhar and Khanun. Mawar and the Tropical Depression in September necessitated the issuance of the Strong Wind Signal No. 3 and the Standby Signal No. 1 in Hong Kong respectively.

2.1.5 Tropical cyclone rainfall

Tropical cyclone rainfall (total rainfall recorded at the Hong Kong Observatory Headquarters from the time when a tropical cyclone comes within 600 km of Hong Kong to 72 hours after it has dissipated or moved more than 600 km away from Hong Kong) in 2017 was 922.1 mm (Table 4.8.1). This accounted for approximately 35.9 % of the year’s total rainfall of 2572.1 mm and was about 27 % above the 1961-2010 long-term average of 728.8 mm.

Severe Tropical Storm Merbok (1702) brought 292.9 mm of rainfall to the Hong Kong Observatory Headquarters (Table 4.8.1) and was the wettest tropical cyclone in 2017.

2.2 Monthly overview

A monthly overview of tropical cyclones is given in this section. Detailed reports on tropical cyclones affecting Hong Kong, including reports of damage, are presented in Section 3.

A tropical depression formed over the sea areas in the southern part of the Philippines about 810 km southeast of Manila on the afternoon of 8 January. It moved west-northwestwards at first with an estimated wind of 45 km/h near its centre.

After making landfall over the coast near Macao and Zhuhai shortly after noon time, Hato entered western Guangdong and gradually weakened. It moved across Guangxi the next day and degenerated into an area of low pressure over Yunnan at night.

Hato brought severe storm surge to the coast of Pearl River estuary. Record-high sea levels were recorded at many places. A maximum storm surge of 2.79 m and a maximum sea level of 6.14 m were recorded at Zhuhai station. The coastal areas in Zhuhai including some underground carparks were flooded by sea water.
