We may have thought La Nina is not coming after all. But we are all wrong. Please see PAGASA's latest update courtesy of the Daily Inquirer.

MANILA, Philippines—The Philippine Atmospheric, Geophysical, and Astronomical Services Administration (Pagasa) on Monday declared the start of the La Niña weather phenomenon, noting that the country will experience above-average rainfall until early 2011.
Pagasa said the cold temperature in the Pacific Ocean that started in July 2010 has persisted, reaching the La Niña threshold.
It described this year's La Niña as “weak to moderate” that will “likely continue at least until 2011, as suggested by the dynamical and statistical model forecasts.”
The La Niña phenomenon refers to the abnormal cooling of ocean surface temperatures in the equatorial Pacific whose effects are usually the opposite of El Niño’s.
The El Niño phenomenon, which the country experienced last year, is the abnormal warming of sea surface temperatures that can result in drought in some areas of the world and storms and extreme wet weather in other parts.
In the Philippines, La Niña brings more rains than usual. The country last entered La Niña in 2007, which brought heavy rains that caused massive landslides in the eastern part of the country.
Pagasa officer-in-charge Graciano Yumul Jr. said the country will experience more rains in the coming months.
“With the persistent anomalous strength of the easterlies over the central and western tropical Pacific, enhanced rainfall during October-December season is likely, coinciding with the start of the northeast monsoon period,” Yumul said in the bulletin.
“Near normal to above normal rainfall condition is expected over most areas of Luzon and general, near normal over the rest of the country,” he added.
