A
weak La Niña has set in, bringing higher rainfall than average
conditions in most parts of Northern Luzon, the Visayas, as well
as central and eastern Mindanao until April this year.
This was announced
by the Philippine Atmospheric, Geophysical and Astronomical Services
Administration (PAGASA) in a meeting at the Department of Science
and Technology headquarters on Tuesday.
According to
Ms. Edna Juanillo of PAGASA, this year’s La Niña is
weak but unusual with its abrupt decrease in sea surface temperatures
(SSTs) compared with the previous episodes wherein the SSTs did
not behave this way.
La Niña
occurs when the SSTs in the central and eastern equatorial Pacific
Ocean become cooler than normal. It recurs, on the average, every
three to seven years and can persist for as long as two years.
According to
PAGASA, Cagayan, Aurora, Quezon, Camarines Sur and Norte, Albay,
Sorsogon, Masbate, Samar, Leyte, Agusan Sur and Norte, Surigao del
Norte, and Davao Oriental will likely have more than average rainfall.
All
government agencies and the public are being advised to prepare
for possible floods, flash floods, and rain-triggered landslides
in hazard-prone areas. (Ofelia F. Domingo, S&T Media Service)
