typhoon mangkhut wind speed
Many incidents of blowing down and falling objects as well as building damages were reported. [86] Schools in Beihai, Qinzhou, Fangchenggang, and Nanning were closed on September 17. 10, the highest level of tropical cyclone warning signals in Hong Kong.
Mangkhut brought damaging winds and severe storm surge to the coast of Pearl River estuary, leading to damages of many buildings and coastal structures, as well as serious inundation of low lying areas. With Mangkhut moving away from Hong Kong and weakening gradually, hurricane force winds no longer affected the territory. Super Typhoon Mangkhut(1822) Maximum gust peak speeds and maximum hourly mean winds with associated wind directions recorded at various stations when the tropical cyclone warning signals for Mangkhut were in force. [77], A storm surge of up to 1.9 metres (6 ft 3 in) affected Macau. MANGKHUT Current Status. Maximum gust peak speeds and maximum hourly mean winds with associated wind directions recorded at various stations when the tropical cyclone warning signals for Mangkhut were in force Maximum 60-minute mean wind speeds and maximum gusts recorded during the passage of Mangkhut and the tropical cyclones necessitating the issuance of No. Typhoon Mangkhut (known locally as Ompong) made landfall in the north-eastern Philippines in the early hours of 15 September 2018. Super Typhoon Mangkhut(1822) 10-minute mean wind direction and speed recorded at various stations in Hong Kong at 2 p.m. on 16 September 2018.
On the other hand, weaker convection and doppler radial wind were observed near the eyewall of Mangkhut comparing with those in its spiral rainband. Mangkhut weakened after entering the northern part of the … The T‐number of Hato rose rapidly, from 5.0 to 6.5, between 0850 and 1000 HKT when an eye was forming, and dropped to 5.5 at 1050 HKT. Satellite images showed that the eyewall near the centre of the storm was considerably disrupted by the terrain of Luzon (Figure 4b). The intense convection at the eyewall of Mangkhut was significantly weakened after it moved across Luzon because of its interaction with land (Figures 8a,b). As Hato's eye moved across the weather station at Huangmao Zhou, the wind speed and pressure data of this station provided a valuable ground truth for the intensity assessment. Electricity supply to over 40,000 households in Hong Kong was interrupted (Figure 2.2.13), including Sai Kung, Cheung Chau, Kat O, Tung Ping Chau, individual buildings in Tseung Kwan O and Heng Fa Chuen, and rural areas in the western and northern New Territories. Maximum wind speed and minimum central pressure could then be estimated from the assigned T‐number and CI. Basic Dvorak enhanced satellite images of Himawari‐8 of (a) Hato (1000 HKT 23 August 2017) and (b) Mangkhut (1200 HKT 16 September 2018). A numbered TC warning system had been introduced in Hong Kong to warn the public about TC‐related hazards since 1917, and the current 1‐3‐8‐9‐10 numbering scheme for TC warning signals has been adopted since 1973 (HKO, 2012; Lui et al., 2018). In fact, the wind strength over Hong Kong was the strongest among the Pearl River Delta region.
[10] The depression soon intensified into a tropical storm, upon which it received the name Mangkhut. The doppler weather radars of the HKO also consistently depicted the well‐defined and intense eyewall of Hato when it came within the 256‐km range of Hong Kong (Figures 5a,c). A second bout of rapid intensification took place as the storm consolidated significantly; a well-defined 39 km (24 mi) eye became established during this time. [19] The typhoon made landfall in Baggao, Cagayan at 2:00 a.m. PST on September 15 (18:00 UTC on September 14), as a Category 5-equivalent super typhoon, with 10-minute sustained winds of 205 km/h (125 mph) and 1-minute sustained winds of 260 km/h (160 mph). There is no tracking data for this storm. 10 at 9:40 a.m. when Mangkhut was about 160 km south-southeast of the territory", "Mangkhut latest: signal No 10 raised as Hong Kong braces for waves up to 14m", "the Hurricane Signal No. Mangkhut reached its peak intensity with a maximum 10‐min sustained wind speed near its centre of about 250kmh–1, before hitting the northern part of Luzon on 15 September 2018. Radar images at an altitude of 3km of Hato (a) at 0730 HKT on 23 August 2017 and Mangkhut (b) at 0900 HKT on 16 September 2018. The No. An air conditioning unit was crashed into an apartment in Lai King, injuring a person inside. This also hints that the maximum sustained wind speed of Hato may have reached 174–185kmh–1 at the time. Local winds were light to moderate northeasterlies during the day of 15 September. 3 Strong Wind Signal was issued at 4:20 p.m. on 15 September when Mangkhut was about 650 km southeast of Hong Kong", "With Mangkhut maintaining its course towards the Pearl River Estuary, the Observatory issued the No. [15][10], Substantial intensification ensued on September 11, as Mangkhut traversed the Philippine Sea. The JTWC analyzed Mangkhut as a Category 2-equivalent typhoon with one-minute sustained winds of 165 km/h (105 mph) as it tracked near Rota, around 12:00 UTC on September 10. The number shown in brackets is assigned by the Japan Meteorological Agency, which is the international identification number of a TC given in four digits. A conclusion is given in Section 4. Figure 3(b) shows the 3‐hourly intensity (maximum sustained wind speed) of Mangkhut based on the best track of the HKO from 14 to 17 September 2018. In Macao, 40 people were injured and more than 5 500 people were evacuated. [69] Insurance claims in Hong Kong amounted to HK$7.3 billion (US$930 million). truetrue.
Mangkhut made landfall over the vicinity of Taishan of Guangdong before dusk.
Time series of 10‐min mean wind speed at HMZ and HM2 and 1‐min mean sea‐level pressure (MSLP) at HMZ on 23 August 2017. The automatic weather station at Clear Water Bay is located on a complex terrain, with the anemometer at an elevation over 70m above sea level. A maximum 10‐min mean wind of 124kmh–1 was also registered on the North Point anemometer located inside the Victoria Harbour, the first time sustained hurricane force winds were recorded at the station since the start of its operation in 1998. Local winds strengthened at night, becoming fresh to strong northerlies. Mangkhut is characterized by its extensive circulation, ferocious winds and fast movement as well as special wind structure.
The height of the inundation in Inner Harbour once reached 1.9 metres or higher above ground. 10 signals in the recent three decades, including York in 1999, Vicente in 2012 and Hato in 2017 (Table 2.2.2). The maximum 60-minute mean wind speeds recorded at Waglan Island and Cheung Chau were 161 km/h and 157 km/h respectively. Mangkhut weakened after crossing the northern part of Luzon and continued to track northwestwards quickly across the northern part of the South China Sea towards the coast of Guangdong. Reconnaissance flights for Mangkhut were conducted by Hong Kong (the HKO in collaboration with the Hong Kong Government Flying Service) and a nearby meteorological organisation on 15 September 2018.
[23][24] In Shenzhen, the storm caused power failures in 13 locations, flooded the Seafood Street, and caused 248 tree falls.
