Residents of Palawan are advised to be vigilant against localized flooding in urbanized and near river areas as the intertropical convergence zone (ITCZ) is forecast to bring heavy rainfall to the province.
In an advisory issued at 11 a.m., the Philippine Atmospheric, Geophysical and Astronomical Administration (Pagasa) said Palawan may expect at least 50 to 100 millimeters of rain from October 31 to November 1 due to the ITCZ.
‘Forecast rainfall may be higher in mountainous and elevated areas. Moreover, impacts in some areas may be worsened by significant antecedent rainfall,’ the weather bureau added.
According to Pagasa, localized flooding is possible mainly in urban, low-lying, or riverine areas. Landslides are also possible in highly susceptible locations.
The ITCZ is a global band near the equator where trade winds from both hemispheres converge. It is a weather disturbance that serves as a breeding ground for low-pressure areas and also triggers rain.
Apart from Palawan, Pagasa earlier said that Metro Manila, Calabarzon, Mimaropa, Western Visayas, Negros Island Region, Zamboanga Peninsula, BARMM, Soccsksargen, Davao Region, and Lanao del Norte are also affected by the ITCZ.
