Weather Today – May 19, 2017 | Rainy Season not official yet


Though rains and thunderstorms are now becoming frequent, PAGASA has clarified in an interview with Panahon TV that Rainy Season is not yet official.

Weather Forecaster Chris Perez says there are certain factors to be considered first before they declare the onset of “tag-ulan”. “Mayroon tayong tinitingnan na synoptic stations sa western side ng Luzon. Dapat sa five out of eight stations, maobserbahan ang at least 25 millimeters of rain sa loob ng three to five days. Bukod dito, ‘yung umiiral na hangin dapat ay Southwest Monsoon o Hanging Habagat.” (We are monitoring synoptic stations in the western section of Luzon. Out of 8 stations, there should be five stations wherein at least 25 millimeters of rain are observed in a period of three to five days.) Last year, the Rainy Season was declared on May 24, 2016.

Today, the Frontal System continues to bring cloudy skies with light to moderate rains and isolated thunderstorms in the regions of Ilocos, Cagayan Valley, Cordillera and Central Luzon. This weather system is the boundary of warm and cold air masses, where convective clouds are
formed. Metro Manila and the rest of the country will experience generally fair weather apart from the isolated rain showers or thunderstorms.

Meanwhile, high temperatures are still expected in several parts of the country. Here are the highest heat indices possible in the next hours.

Metro Manila – 39. 4°C
IloIlo/Bacolod City – 39.3°C
Tuguegarao City – 39.1°C
Metro Cebu – 38.3°C
Legaspi – 38.1°C
