Tropical Storm Nida (2016)

Meteorological history

During July 28, the Japan Meteorological Agency started to monitor a tropical depression that had developed about 1,020 km (635 mi) to the east-southeast of Manila in the Philippines. The system had a broad low level circulation center which was consolidating, with atmospheric convection developing to the north and south of the depression. The system was also located within a favorable environment for further development with low vertical wind shear and very warm sea surface temperatures. Over the next day as the system moved north-northwestwards under the influence of a subtropical ridge of high pressure, deep atmospheric convection started wrapping into the system's low level circulation center. The United States Joint Typhoon Warning Center subsequently issued a tropical cyclone formation alert during July 29, as the system rapidly consolidated further, while the global models indicated that tropical cyclogenesis would take place during the next 24 hours. During that day as the system consolidated further, both PAGASA and the JTWC initiated advisories on the system, with the former naming it Carina, while the latter classified it as 06W.

On July 31, Nida made landfall over the area between Baggao and Gattaran of the Cagayan province in the Philippines at 13:20 PST (05:20 UTC) as a severe tropical storm. At 03:35 CST on August 2 (19:35 UTC on August 1), Nida made landfall over Dapeng Peninsula of Shenzhen, Guangdong, China as a severe tropical storm.

In post-analysis, the JMA downgraded Nida's peak intensity into a severe tropical storm with winds of 110 km/h. However, most other agencies consider Nida as a minimal typhoon at peak intensity.

Philippines

Before tropical storm Nida (known as Carina in the Philippines) made its landfall through Cagayan province, PAGASA raised a public signal warning number 2 throughout the Cordillera Administrative Region. While it lashes the Northeastern part of the Philippines, the provinces of Isabela, Cagayan, Quirino Province, Abra, Mt. Province, Benguet, Kalinga Province, and Ifugao Province reported that some of their major roads was not passable due to landslides. Despite the local governments of the said areas reported that there are no casualties, they still reported that some of them are injured during the typhoon.

Mainland China

The typhoon impacted five provinces across southern China (Guangdong, Guangxi, Guizhou, Hunan, and Yunnan), affecting 495,000 people. Of those affected, 37,000 required evacuation and 2,100 needed emergency assistance. Approximately 300 homes and 2,700 hectares (6,700 acres) of crops were destroyed while another 2,400 homes and 16,900 hectares (42,000 acres) of crops were damaged. Total economic losses reached ¥510 million (US$76.9 million).

Hong Kong

The typhoon led to the cancellation of over 180 flights at the Hong Kong International Airport. Gale to storm force winds of up to 100 kilometres per hour downed numerous trees during the passage of the eyewall. Although the city was hit directly by the typhoon, the highest tropical cyclone warning signals were not necessary as the wind strength did not justify the issuing of higher signals, due to Nida weakening after landfall. However, the No. 8 tropical cyclone signal was kept in force for 16 hours.

Vietnam

Nida killed 4 people in Northern Vietnam and left 7 others missing. A suspension bridge in Bát Xát district was washed away, leaving 16 households isolated. The storm also destroyed 17 homes in the country and damaged substantial areas of crops. Internet services in Vietnam were also slowed down after a submarine cable was cut during the storm.
