PAGASA warns of 4 tropical cyclones entering RP in June
by Rutchie Cabahug-Aguhob
Cagayan de Oro City (2 June) -- At least four tropical cyclones are expected to enter/develop in the Philippine Area of Responsibility (PAR) in the month of June, this year.
This is indicated in the "Seasonal Climate Outlook for the Philippines from January to June, 2009" of the Climate Monitoring and Prediction Center (CLIMPC), Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) that monitors and gives updates on the atmospheric and oceanic conditions affecting the country.
"The southwest monsoon (SW) is expected to set in completely this month and rainfall conditions during the period are likely to be near normal," Ricardo Mercado, Officer-in-Charge of PAGASA, Region 10, said.
Per CLMPC, the months from April-June, represent the first half of the SW monsoon season, commonly known as "Habagat" and winds gradually shifted from the North East NE to the South East that extended up to mid May when the onset of the rainy season followed.
During April, above-normal rainfall conditions were detected mostly over the areas of the Bicol Region, Eastern and Central Visayas, Agusan del Norte, Agusan del Sur and Southern Tagalog Regions while that of May was expected to be near-normal in most parts of the country with some patches of below normal rainfall over Southern Luzon and Visayas.
However, normal onset of the rainy season associated with the SW monsoon prevailing in areas under Type 1 climate was also predicted to start from the second half of May up to the first half of June.
On the other hand, the neutral El Niņo Southern Oscillation (ENSO) condition has continued during December 2008, although equatorial sea surface temperatures (SST) significantly cooled across parts of the central and eastern equatorial Pacific Ocean.
The CLMPC said colder SST anomalies developed along the equatorial zone due to stronger-than-normal trade wind flow during the later part of 2008.
Despite this recent cooling in the equatorial Pacific, however, most international coupled climate models predicted neutral conditions up to the middle of 2009 likely enhancing the rainfall in some areas of the country, particularly, the Visayas and Eastern and Northern Mindanao, Mercado added.
