Flooding in northern Luzon caused damage to buildings and infrastructure. According to NDRRMC, 103,662 people were impacted when Nesat moved through, with 4,459 displaced; there were no fatalities. A final report by PDRRMO estimated infrastructure and agricultural damage at ₱474.2 million (US$8.15 million). Tropical Storm Haitang Since October 14, a non-tropical low with subtropical characteristics started to persist north of Minamitorishima and northwest of then-degenerating Tropical Depression 21W. The low remained stationary, slowly weakened and acquired more tropical characteristics next three days, and JTWC eventually declared a tropical depression early on October 18 when the system had been deepening again and became compact. Although the JMA reported a gale-force non-tropical low at the same time, the system was soon analyzed as a tropical storm and named Haitang. The center of the storm soon became weakly-defined as extensive dry air entrained the storm, prompting the JTWC to downgrade the storm into a tropical depression and issue their final advisory late on the same day. The JMA, however, continued to issue advisories on the storm as it moved northeastwards, and transitioned into an extratropical cyclone on October 19. Tropical Depression 25W (Obet) A tropical depression formed northeast of the Philippines on October 18, given the name Obet by PAGASA. The following day, the JTWC upgraded it to a tropical depression, designating it 25W. It was initially expected to be a tropical storm, but never intensified as expected. According to Municipal Disaster Risk Reduction & Management Office (MDRRMO), two deaths, a fisherman and his wife, were reported due to 25W. Severe Tropical Storm Nalgae (Paeng) On October 26, the JTWC reported in its TCFA (Tropical Cyclone Formation Alert) that a low pressure area near the Philippines was able to develop because of warm waters and low wind shear. The agency designated it as Invest 93W. The JMA and the PAGASA then classified the disturbance as a tropical depression, with the latter assigning the name Paeng to the system. The JTWC upgraded the system to a tropical depression a day later, at 00:00 UTC on October 27, and it was given the designation 26W. At the same time, the JMA upgraded the typhoon to a tropical storm, and was named Nalgae. The following day, PAGASA and JTWC classified it as a severe tropical storm approaching the northeast of the Philippines. PAGASA issued danger alerts (Signal No. 3), informing that damage could be registered as
