Aside from cold temperatures, PAGASA warns the ongoing La Niña may enhance the northeast monsoon, which could trigger floods and landslides

The state weather bureau declared the onset of the northeast monsoon or hanging amihan in the Philippines on Friday, November 6.

“Surges of cold temperatures” are now expected in the coming months, said the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) in a statement.

“The northeast windflow is expected to gradually become more dominant over Northern Luzon, bringing cold and dry air,” PAGASA explained.

The declaration was made based on these observations in the past several days:

  • “strong to gale-force northeasterly winds have prevailed over Northern Luzon due to the strengthening of the high pressure system over Siberia and enhanced by passing tropical cyclones”
  • “gradual cooling of the surface air temperature over the northeastern part of Luzon”

It’s not just cold temperatures, however, that would be seen in the coming months.

PAGASA warned that due to the ongoing La Niña, the northeast monsoon may be enhanced, and it could trigger floods as well as landslides.

“Therefore, all concerned government agencies and the public are advised to take precautionary measures,” said the state weather bureau.

In early October, PAGASA warned that La Niña would cause more rain than usual.

“Above normal rainfall” is expected in most areas of the country during the last quarter of 2020 and early months of 2021. (READ: FAST FACTS: Tropical cyclones, rainfall advisories) –
