Typhoon RAI (Odette)
On the night of 14 December 2021 Typhoon Rai (Odette in the Philippines), which had originated from a tropical disturbance near the equator on 10 December, forming near the site of another low-pressure area that had dissipated on the previous day, entered the Philippine Area of Responsibility (PAR). The next day the system’s intensity was raised to a low-end Category 1-equivalent typhoon. However, while approaching the Philippines, Rai unexpectedly and rapidly intensified into a Category 5 super typhoon.
