La Niña Looms
Based on PAGASA’s 96th Climate Outlook Forum held yesterday, the La Niña Watch is still in effect.
La Nińa is characterized by unusually cool ocean surface temperatures in the Central and Eastern Equatorial Pacific (CEEP).
Since September 2017, cold ocean conditions persisted, indicating that La Niña is developing. According to PAGASA, the La Niña Advisory or the actual Weak La Niña phenomenon may begin next month, but is not expected to last beyond March 2018. During this event, above-normal rainfall in different parts of the country may occur. Impacts also include slightly warmer air temperatures, though the Amihan may bring surges of cold temperatures in the northern and eastern parts of Luzon.
The country may also experience a higher chance of tropical cyclone occurrences that may bring much rainfall during the remaining days of 2017 until the first quarter of 2018.
