The Filipinos were warned about high waves, strong winds and very heavy rains over the weekend with storm signal 4 raised in parts of the Nation.

The typhoon hardly moved in 24 hours bringing relentless rains to the archipelago causing the retaining wall of Baguio's dump facility to collapse.

[4] Later that day, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) started monitoring the system as a tropical depression and named it Mina.

This prompted the JTWC to change its forecast on the system, from turning east and interacting with Talas, to move west and hit the Philippines.

The typhoon developed a large eye with a diameter of 18 nautical miles (33 km; 21 mi) with highly symmetric deep convective bands wrapped into it.

[13] Nanmadol continued to drift north west and made landfall over Gonzaga, Cagayan, Philippines with strong winds of over 95 knots (176 km/h; 109 mph).

[14] After interacting with land, the eye of Nanmadol became cloud filled and the eyewall in the northern semicircle became eroded causing the system to weaken.

At that time, it was located approximately 245 nautical miles (454 km; 282 mi) south of Taipei in the periphery of a mid-level subtropical ridge.

[24] Soon, Nanmadol accelerated towards the northwest and entered the Taiwan Strait, with fragmented convective bands wrapped into an adequately defined center.

Landfall weakened the system rapidly prompting the JTWC to downgrade Nanmadol to a tropical storm with winds of under 50 knots (93 km/h; 58 mph).

[28] After its third landfall over Fujian, China, Nanmadol weakened rapidly prompting both the JTWC and the JMA to issue their final warnings on the system.

[31] On the next day, as the Nanmadol became dangerously strong, storm warning signal 3 was raised over the provinces of Isabela and Cagayan, including the Babuyan Islands.

[33] The Philippine Department of Health issued a white alert to its subordinates all along Nanmadol's path, ordering them to stock up on medicines and supplies so that the victims need not purchase them at the time of need.

[36] Also, the Philippine Atmospheric, Geophysical and Astronomical Services Administration reported that though Nanmadol was intensifying rapidly, heavy rains were no longer expected.

[38] On August 26, the Central Weather Bureau issued a sea warning as they were no longer expecting a Fujiwhara effect, which could possibly pull Nanmadol away from Taiwan.

[40] On August 27, the Central Emergency Operation Center of Taiwan announced that they were completely prepared for any kind of contingencies triggered by the typhoon.

[43] On August 28, Ma Ying-jeou, the President of the Republic of China ordered evacuations of thousands of people from vulnerable areas, saying that a slow moving typhoon could result in more damages and casualties than normal.

[46] Also, the Taiwan Railway Administration halted services on the South-Link Line in fear that heavy rain could trigger landslides and cause rail-accidents.

[48] The Maritime affairs bureaus of Fuzhou, Putian, Quanzhou, Xiamen and Zhangzhou cities activated the red warning, the highest level on the Chinese scale, ordering all ships to return to the harbor as soon as possible.

[49] The storm was expected to bring heavy torrential rains and flash flooding as is makes landfall on the southern part of Fujian province.

[50] For safety insurance, bullet trains along the Wenzhou-Fuzhou and Fuzhou-Xiamen high-speed rail lines were ordered to either operate slowly or suspend services completely if the surveillance system detects any hazards.

Also, the shipping route linking Xiamen, in east China's Fujian Province, and Kinmen (Quemoy), in Taiwan was closed at 14:00 local time as the storm entered the strait.

[51] The seawalls originally built to resist Nanmadol's strong storm surge were discovered with several cracks, each measuring two meters in length along Jinjiang's coast in the village of Weitou.

[52] On August 23, the system's rainbands caused heavy rains in the Philippines's Zamboanga del Sur province triggering a landslide.

[58] Another big issue was that the typhoon slowed down after landfall and did not move much in six hours, leaving the northern half of the nation in danger for a longer period of time.

[63] The typhoon hardly moved in 24 hours bringing relentless rains to the archipelago causing the retaining wall of Baguio's dump facility to collapse.

[75] The Council of Agriculture soon issued a red-alert for six riverside areas advising people that are at a high risk of mudslides after heavy torrential rains dumped by the typhoon.

[78] Some 30,000 households in southern and eastern Taiwan did not have electricity, 8,000 people were evacuated and several roads and bridges were closed due to the heavy rain.

[82] Nanmadol made landfall in China as a weak tropical cyclone bringing heavy rains, prompting local authorities to issue flood and landslide warnings.

[88] On September 1, Chinese state owned news agency Xinhua reported that The storm has caused direct economic loss of 130 million yuan or US$20,354,807 with two deaths, twenty injuries and six missing in the Fujian Province.
