Cebu, Philippines

known in the Philippines as Typhoon Odette, was a powerful and catastrophic tropical cyclone that struck the Philippines. Rai became the first Category 5-equivalent super typhoon to develop in the month of December since Nock-ten in 2016, and the third Category 5 super typhoon recorded in the South China Sea, following Pamela in 1954 and Rammasun in 2014. The 22nd tropical storm, the ninth typhoon, and the fifth super typhoon of the 2021 Pacific typhoon season, the system originated from a tropical disturbance near the equator on December 10, forming near the site of another low-pressure area that had dissipated on the previous day. Conditions around the system were favorable for further development, and it slowly developed into a tropical depression on December 12. On the same day, the United States Joint Typhoon Warning Center (JTWC)[nb 1] issued a Tropical Cyclone Formation Alert (TCFA) on the consolidating depression. Further intensification ensued, and Rai was upgraded to a tropical storm the next day, before passing south of Ngulu Atoll. After passing near Palau and impacting the island nation, Rai entered the Philippine Area of Responsibility (PAR) by the night of December 14, where the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) named it "Odette". On the next day, both the JMA and JTWC raised the system's intensity to a low-end Category 1-equivalent typhoon, as an eye continued to appear. While approaching the Philippines, Rai unexpectedly rapidly intensified into a Category 5 super typhoon[nb 2] just before its first landfall across Siargao. It then slowly but steadily weakened as it traversed the Visayas, exiting into the Sulu Sea. After making its last landfall over Palawan, Rai continued to weaken before unexpectedly re-intensifying into a Category 5-equivalent typhoon by December 18, while nearing Vietnam. On the next day, Rai entered yet another weakening phase, dissipating on December 22, southeast of Hong Kong.
