Typhoon Damrey (2017)

Formation and track

Typhoon Damrey formed as a tropical depression over the South China Sea on 31 October 2017 and intensified as it moved west toward the Vietnamese coast^[1][2][3]. Japan's Meteorological Agency tracked it as a typhoon before landfall; Wikidata catalogues the storm as a Pacific typhoon of 2017 and records the same formation date^[3]. The system dissipated over land on 4 November 2017 according to Vietnamese reporting^[2], or on 5 November 2017 according to the English language Wikipedia account and Wikidata^[1][3].

Landfall in Khanh Hoa

Sources disagree on the precise time and place of landfall. Vietnamese meteorological and press reporting places it at Ninh Hoa town, on the Khanh Hoa coast, at about 06:30 local time on 4 November 2017^[2]. The English language Wikipedia article instead places landfall in Van Ninh district, also in Khanh Hoa, at 03:00 UTC on 4 November 2017, about 10:00 local time^[1]. Ninh Hoa and Van Ninh are both on the Khanh Hoa coast, a short distance apart.

Japan's Meteorological Agency measured the maximum sustained wind, averaged over ten minutes, at 130 km/h, with a minimum central pressure of 970 hPa; the United States Joint Typhoon Warning Center measured a one minute sustained wind of 165 km/h and a minimum pressure of 967 hPa^[1]. Vietnamese reporting described gusts of level 12 to 13 near the coast at Ninh Hoa, with the storm's peak gust given elsewhere as level 15^[2].

Casualties and damage

The storm killed 44 people and left 1 person missing in Khanh Hoa province, with 229 injured, according to the Vietnamese Wikipedia account^[2], a figure repeated in the English language Wikipedia article^[1]. Economic losses in the province were estimated at more than 15,500 billion dong, about US$696 million^[1][2].

Across Vietnam as a whole the storm killed 107 people, injured 342 and left 16 missing, with total damage of about 22.68 trillion dong, or roughly US$998 million to US$1 billion^[1][2]. The English language Wikipedia infobox gives a combined total of 142 fatalities across every country the storm affected, including 8 deaths in the Philippines and 1 in Cambodia; those per country figures add to 116, and no fetched source explains the remaining difference^[1].

Impact on Nha Trang

Same day reporting described thousands of trees uprooted or snapped in Nha Trang, with shopfronts on Trần Phú street losing their roofs or collapsing outright, and Vĩnh Hòa ward flooded badly enough to cut off some households^[5]. A separate report gave 46 houses collapsed and more than 5,200 with roofs torn off in the city, alongside damage to dozens of irrigation channels and to telecommunications masts^[4].

Casualty counts reported on the day of landfall were provisional and lower than the final toll. One report gave 12 dead in Khanh Hoa province as of 17:30 on 4 November 2017, rising to 20 dead and 17 missing in a later update the same day^[5]; another put the toll at 11 dead and 10 missing across Phu Yen, Khanh Hoa and Binh Dinh combined at a similar hour^[4]. Both were superseded by the final count of 44 dead in Khanh Hoa province^[1][2]. About 30,000 residents and tourists were evacuated from the Nha Trang resort area ahead of and during landfall^[1].
