Expect colder days ahead with the onset of the northeast monsoon, locally called “amihan,” the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said on Monday, Oct. 25.
For the past several days, PAGASA observed the prevalence of strong to gale-force northeasterly winds over Northern Luzon due to the strengthening of the high-pressure system over Siberia and enhancement by the passing of low pressure areas.
Moreover, PAGASA observed the gradual cooling of the surface air temperature over the northeastern part of Luzon.
“These meteorological conditions indicate the onset of northeast monsoon (amihan) season in the country,” PAGASA Administrator Dr. Vicente Malano said in a statement.
“With these developments, the northeast wind flow is expected to gradually become more dominant over Northern Luzon, bringing cold and dry air,” he added.
As such, surges of cold temperatures will likely prevail in the coming months.
Meanwhile, PAGASA said that with the ongoing La Niña, rains associated with the northeast monsoon will likely be enhanced, which could trigger floods, flash floods, and rain-induced landslides over susceptible areas.
PAGASA advised the public, as well as government agencies concerned, to take precautionary measures to mitigate the potential impact of extreme rainfall events.
