Above-normal rainfall to ease as La NiAa decays

MANILA-- The country will experience in the forthcoming days a lesser incidence of above-normal rainfall that has characterized the La NiAa-like conditions in previous weeks.

Such rainfall will not continue to linger as the 2016-2017 La NiAa has decayed, according to the state weather bureau, PAGASA.

"Latest data indicate such La NiAa is over," said Analiza Solis, OIC of PAGASA's Climate Monitoring and Prediction Section.

Some rains that may still occur will just be remnants of the La NiAa-like conditions previously seen in the country, she noted.

Solis said latest data show that La NiAa conditions no longer exist in the central and eastern equatorial Pacific (CEEP).

"La NiAa-like patterns of above-normal rainfall in some flood- and landslide-prone areas, especially in Mindanao, aren't likely to linger as noted in forecasts," PAGASA also said in a Feb. 28 statement.

PAGASA does not expect either La NiAa or El NiAo conditions to develop in the equatorial Pacific basin within the next three months.

Solis said several international dynamical models indicate El NiAo's possible recurrence later this year.

The bureau will continue monitoring conditions in the Pacific and update the public on developments there that can affect the country, she added.

According to experts, La NiAa and El NiAo are the warm and cool phases of the El NiAo-Southern Oscillation (ENSO) cycle.

They said ENSO is a naturally occurring phenomenon of the climate system resulting from ocean-atmosphere interaction in CEEP.

"ENSO-neutral conditions are present in tropical Pacific and are favored to continue through at least the March-April-May 2017 season," Solis said Wednesday at a forum in Metro Manila.

With the transition to ENSO-neutral conditions, PAGASA announced the termination of its La NiAa watch.
