In December 2022, a series of floods began to severely affect the provinces of Misamis Occidental and Misamis Oriental, and some parts of the southern island of Mindanao in the Philippines. The floods were caused by intense rain, which poured down on the central and southern parts of the country.^[4]^[5]^[6]^[7]

Cause

The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said in a statement that the widespread rains were triggered by the shear line collision located within the regions of Visayas and Mindanao. The shear line then persisted towards the Eastern Visayas and CARAGA regions in the central and northern parts of the country.^[8]^[9] Low pressure areas and northeast monsoon also contributed.^[10]

Impact

The provincial government of Misamis Occidental declared a state of calamity (SOC) as they received the full brunt of the flooding. The cities of Gingoog, Ozamiz, and provincial capital of Oroquieta, as well as surrounding municipalities were most affected by the floods.^[11] Samar, Northern Samar and Eastern Samar also declared SOC.^[12]^[13]^[14]
