Weather Today – May 10, 2017 | Warm mid-week

Warm weather is expected but rains are still possible today, Wednesday. The Low Pressure Area (LPA) previously monitored outside the Philippine Area of Responsibility (PAR) is now embedded along the Intertropical Convergence Zone (ITCZ), the boundary of winds coming from the Northern and Southern Hemispheres. When these winds converge, convective clouds are formed, bringing high chances of rains.

The ITCZ is expected to dump light to moderate rains and isolated thunderstorms in Mindanao, Central and Western Visayas, and Negros Island. Residents are advised to monitor updates as PAGASA may issue rainfall warnings in the next hours.

Prevailing in the eastern section of the country are Easterlies or winds coming from the Pacific Ocean that becomes dominant during “tag-init”. This weather system is responsible for the warm and humid weather that we experience in most parts of the country. In the next hours, Metro Manila and the rest of the archipelago will experience partly cloudy to cloudy skies with chances of isolated rain showers or thunderstorms mostly in the afternoon or evening.

Along with the prevailing Easterlies are the rising temperatures and heat indices. Heat index determines how the human body perceives the heat. It’s how we feel when the air temperature is combined with the relative humidity in a specific location. Below is the heat index forecast:


(SBMA, Olongapo – 37.1 °C
Tuguegarao City – 36.5 °C
Metro Manila – 36.4 °C
Ilo-Ilo / Bacolod – 36.2 °C
Metro Davao – 36.1 °C)

Question of the Day

While the heat is still on, thunderstorms are also becoming more frequent. One of Panahon TV’s followers, Dan Joshua Apura, asked “Kailan mag-uumpisa ang Rainy Season sa bansa?”(When can we expect the onset of Rainy Season in the Philippines?)

According to PAGASA Weather Forecaster Chris Perez, the onset of “tag-ulan” usually occurs during the second half of May until the early part of June. “Itong mga nararanasan nating thunderstorms, hindi pa ito ‘yung actual na onset ng Rainy Season. Pero ito po ay indicator na sa mga darating na araw o linggo ay posible nga na tuluyan nang magdeklara ang PAGASA na umpisa na ng tag-ulan dito sa ating bansa.”, Perez explained.(Frequent thunderstorms don’t signify that Rainy Season has begun. However, this may be an indicatorfor PAGASA to declare “Tag-ulan” in the coming days or weeks.)
