After brushing Luzon, seven people perished, over 30,000 homes were damaged, 100 houses were destroyed, and 7,000 individuals were left homeless.

Even though Lynn passed a bit south of Taiwan, the storm brought widespread damage to the nation.

Typhoon Lynn originated from a broad, poorly organized area of convection situated within the monsoon trough roughly 370 km (230 mi) north-northeast of the Marshall Islands in the middle of October 1987.

The Joint Typhoon Warning Center (JTWC) started monitoring the system on October 14,[2] and later that day, the Japan Meteorological Agency (JMA) followed suit.

[3][nb 1] Following an increase in convection and outflow, the JTWC issued a Tropical Cyclone Formation Alert (TCFA) for the system at 0300 UTC on October 15 about 670 km (415 mi) north-northwest of Pohnpei of the eastern Carolina Islands at the time.

Three hours later, the JTWC classified the system as Tropical Storm Lynn based on Dvorak estimates of 65 km/h (40 mph).

[3] At midday, Lynn made its closest approach to Guam, passing around 150 km (95 mi) northeast of the island.

[2] After moving away from the Mariana Islands,[2] Lynn initially maintained its intensity, but on August 19,[3] it began to rapidly intensify.

[2] Meanwhile, the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) also monitored the storm and assigned it with the local name Pepang.

Roughly 24 hours later, the JMA reduced the intensity of Lynn to 145 km/h (90 mph);[3] by this time, the typhoon entered the Luzon Straits.

Over the next two days, Lynn interacted with mountainous terrain of the Philippines; however, at its closest approach, the core of the system remained over 200 km (120 mi) offshore.

[7] Increased wind shear took toll on Lynn, and the next day, satellite imagery indicated that all of the storm's deep convection was confined north-northeast of the center.

At 0000 UTC on October 27, the JTWC ceased watching the system,[2] though the JMA continued tracking it until the morning of August 28.

[17] A few weeks later, the Northern Marianas Islands were declared a major disaster area by the Federal Emergency Management Agency (FEMA).

[25] Due to the threat of both storm surge and high waves, low-lying residents were advised to evacuate their homes.

[26] A total of five towns were flooded in Cagayan and Ilocos Norte provinces, while Lynn triggered landslides in Benguet.

[30] Despite not striking the country directly, Typhoon Lynn brought torrential rains to much of the island from October 24–26, including a maximum of 1,700 mm (67 in) in Taipei.

[35] In Taipei, torrential rains deluged the city and resulted in landslides that destroyed numerous dwellings and took 13 lives.
