Part of the 2024 Pacific typhoon season

Typhoon Man-yi, known in the Philippines as Super Typhoon Pepito, is a weakening tropical cyclone which recently emerged off the coast of Ilocos Sur after making landfalls in Aurora and Catanduanes. Closely following Tropical Storm Trami and Typhoons Kong-rey, Yinxing, Toraji and Usagi, Man-yi became the sixth consecutive tropical system to cross the country in less than a month. Additionally, it was the first time since records began in 1951 that four storms—Yinxing, Toraji, Usagi, and Man-yi—had existed simultaneously in November.

The twenty-fourth named storm, the third violent typhoon of the season, and the sixth super typhoon of the annual typhoon season, Man-yi originated from an area of convection 220 km (140 mi) east of Kwajalein Atoll on November 8. Satellite imagery showed a more organized low-level circulation center and persistent deep convection on the southwestern periphery. As the system moved northwestward, the Japan Meteorological Agency (JMA) upgraded it to a tropical storm, naming it Man-yi, as the system passed Guam on November 13. Later, on November 15, the JMA upgraded it to a minimal typhoon, with the Joint Typhoon Warning Center (JTWC) following shortly thereafter. Early the next day, the JMA reported that the storm reached its peak intensity with ten-minute sustained winds of 195 km/h (120 mph) and a central pressure of 920 hPa (27.17 inHg). It subsequently peaked as a Category 5-equivalent super typhoon on the Saffir-Simpson scale, with one-minute sustained winds of 260 km/h (160 mph). As it moved west-northwestward, Man-yi made its first landfall in Panganiban, Catanduanes, later the same day. After making landfall in Catanduanes, the system slightly degraded in appearance, with the western half becoming less organized as it passed north of the Calaguas Islands. The typhoons eye had become more distinct, and its structure seemed to have recovered, with the development of a secondary eyewall, suggesting that the system was undergoing an eyewall replacement cycle, although the cycle could not be completed. The following day, Man-yi made its second landfall in Dipaculao, Aurora, on Luzon Island. The typhoon accelerated northwestward over the South China Sea, with its low-level circulation center partially exposed and fragmented convective bands occurring along the southern and eastern edges of the system.

A tropical storm watch was issued for the Mariana Islands, prompting Guam to declare a state of emergency in preparation for the storm's arrival, while a flood watch was also issued for parts of Guam and the Northern Marianas. PAGASA issued Tropical Cyclone Wind Signals for several areas, while PHIVOLCS issued warnings about potential lahar flows from Taal, Pinatubo, and Mayon volcanoes. Mandatory evacuations were ordered in vulnerable areas of Camarines Sur, Catanduanes, Calabarzon and Eastern Samar. Panic-buying occurred in several locations, while multiple events and transportation services were suspended. Overall, Man-yi was responsible for eight deaths, five injuries, three missing, and approximately US$17,367 in damages, particularly in Catanduanes and Nueva Vizcaya.
