In Pagasa’s latest climate monitoring bulletin as of January 21, most of Luzon is still getting less than normal rainfall.
Observed rainfall in most parts of Luzon for the period of January 1 to 21 is less than 50 millimeters which state meteorologists say is below normal.
This is despite the effects of the northeast monsoon, which has been bringing light rains in Luzon in the past few days.
In a previous El Niño advisory, Pagasa said that a strong El Niño phenomenon will be experienced in the country until February.
