Warm Weather on Rizal’s Birth Anniversary
The Ridge of a High Pressure Area (HPA) continues to bring generally fair weather in the country. This weather system suppresses cloud formation, causing lesser chance of rains. As it prevails today, partly cloudy to cloudy skies prevail in Luzon, Visayas and Mindanao though isolated rain showers and thunderstorms are still possible.
In an interview with PAGASA Weather Forecaster Samuel Duran, he mentioned that no weather disturbance is expected to affect the country within the next two to three days.
While it’s a back-to-work Monday in most areas of the country, some provinces are enjoying an extended vacation today. These include Ifugao, which celebrates its provincial foundation anniversary, and Laguna, the birthplace of Dr. Jose Rizal whose birth we commemorate today.
Here are expected weather conditions and temperatures in these areas:
Warm Wednesday and Monsoon Break
In the midst of the Rainy Season, generally fair and warm weather is expected with the presence of the Ridge of a High Pressure Area (HPA) today.
“Ridge” refers to the extended part of an HPA or an anticyclone. Unlike a Low Pressure Area, this indicates an area where the atmospheric pressure is higher than its surroundings. Formation of clouds is usually suppressed, thus, less chance of rains. As it extends across Luzon, partly cloudy to cloudy skies will prevail in Metro Manila and the rest of the country only with isolated rain showers or thunderstorms.
In an interview with PanahonTV, PAGASA Weather Forecaster Robert Badrina said that the country is on a monsoon break.
Badrina also said that the country will experience a storm-free week.
Potential LPA spotted
A possible weather disturbance was spotted in Mindanao today.
Based on an interview with PAGASA Weather Forecaster Meno Mendoza, the possible Low Pressure Area (LPA) is embedded along the Intertropical Convergence Zone or ITCZ.
“Ang nakapaloob dito sa ating Intertropical Convergence Zone ay mga maliliit na vortices ng Low Pressure Area at posible itong panggalingan nga ng sama ng panahon.” (Embedded within the Intertropical Convergence Zone are small vortices of Low Pressure Area, which may develop into a weather disturbance.)
Considered to be a breeding ground of weather disturbances, the ITCZ refers to the area where winds from the Northern and Southern Hemispheres meet and create interaction. Meanwhile, vertices are mass of whirling air that may develop into weather disturbances.
Today, Mindanao and Eastern Visayas will continue to experience light to moderate rains and thunderstorms this Thursday. In the rest of the country including Metro Manila, partly cloudy to cloudy skies will prevail with isolated rain showers or thunderstorms.
ITCZ soaks parts of Mindanao
The Intertropical Convergence Zone (ITCZ) continues to affect Southern Mindanao.
ITCZ is characterized as an area where winds coming from the Northern and Southern Hemispheres meet; this interaction results to rains in the affected areas.
As this weather system prevails, cloudy skies with light to moderate rains and thunderstorms will be experienced in Mindanao today. Rains have been affecting the region since last week, prompting the cancellation of classes and declaration of State of Calamity in Kabuntalan and other areas in Maguindanao due to widespread flooding.
Light to moderate rains will also affect the regions of Central Visayas and Negros Island. In the rest of the country including Metro Manila, partly cloudy to cloudy skies will prevail only with isolated rain showers or thunderstorms.
Rainy first day of school in parts of Luzon and Mindanao
According to the Department of Education, an estimated 28 million students officially opens the school year 2017-2018 today. As students and teachers head back to school, rains will prevail in some parts of Luzon and Mindanao.
According to PAGASA, the Southwest Monsoon or Habagat is still affecting the western section of Northern and Central Luzon, while the Intertropical Convergence Zone (ITCZ) is affecting Southern Mindanao. Due to these weather systems, cloudy skies with light to moderate rain showers and thunderstorms will be experienced in the Ilocos Region, Zambales, Bataan, Maguindanao, Soccsksargen and Davao Del Sur including Davao City. In the rest of the country including Metro Manila, partly cloudy to cloudy skies will prevail except for isolated rain showers or thunderstorms.
In an interview with PAGASA Weather Forecaster Samuel Duran, he mentioned that morning rains will be more frequent as Habagat prevails.
However, Duran clarified that there is no weather disturbance in the county within the next three days.
Moderate rains continue in Palawan
The Southwest Monsoon, locally known as Habagat continues to affect the eastern section of Luzon.
As this weather system prevails, Palawan will continue to experience light to moderate rain showers and thunderstorms. In the rest of the country including Metro Manila, partly cloudy to cloudy skies will prevail only with isolated rain showers or thunderstorms.
With rains concentrated in Palawan, humid weather is still expected to prevail in most parts of the country.
Get to Know Habagat
Every year, when the rainy season begins, Habagat begins to affect the country. Due to its warm and moist characteristics, Habagat causes monsoon rains that could last for a couple of days or even a week. Here are things you must know about this weather system:
Light to moderate rains in Palawan
On the first Saturday of June, the Southwest Monsoon, which is warm and moist air locally known as Habagat is still affecting the western section of Luzon.
As this weather system prevails, cloudy skies with light to moderate rain showers and thunderstorms will be experienced in the province of Palawan. In Metro Manila and the rest of the country, partly cloudy to cloudy skies with isolated rain showers or thunderstorms will prevail.
While the Habagat dumps rains on some parts of Luzon, residents are alerted against heavy rains, which may trigger flash floods and landslides. It can be recalled that five persons perished in a landslide that occurred in Puerto Princesa City, Palawan last Monday night. According to reports, the victims were composed of a family of four and an infant.

However, PAGASA Weather Forecaster Meno Mendoza clarified that there is no weather disturbance affecting the country.
In a press statement, the weather bureau said that widespread rainfall has been observed these past few days. Most parts of the country are likely to experience near to above-normal rainfall conditions in June to July. However, breaks from the rains will occur, possibly lasting for several days to weeks due to the persistence of the Ridge of High-Pressure Area in the North Pacific.
In an interview with PAGASA Weather Forecaster Gener Quitlong, the following criteria for declaring the onset of tag-ulan have been satisfied:
– A total rainfall amount of 25 millimeters or more in three consecutive days which must be recorded at no less than five of these stations: Laoag, Vigan, Dagupan, Iba, Mindoro Occidental, Ambulong, Iloilo, and Metro Manila
– Widespread rainfall due to the prevailing winds brought by the Southwest Monsoon or Hanging Habagat
– Daily thunderstorm activity
To help you stay protected on rainy days, make sure you have the following:
Frontal system and Habagat bring rains to Luzon
Rains will prevail in most parts of Luzon on the last Sunday of May 2017.
According to PAGASA, the Frontal System is affecting the extreme Northern Luzon, while the Southwest Monsoon dominates the western section of Northern and Central Luzon. Frontal System refers to the boundary of two different air masses. Once this weather system becomes dominant in an area, it will generate convective clouds which will bring thunderstorms. Southwest Monsoon is defined as warm and moist winds moving in a southwest direction. Due to these characteristics, Habagat can cause monsoon rains that can last for a couple of days or even a week
As these weather systems prevail today, Ilocos Region, Cordillera and Batanes will experience moderate to occasionally heavy rains and thunderstorms. Residents of these areas are alerted against flash floods and landslides. In Central Luzon and the rest of Cagayan Valley, light to moderate rains and thunderstorms will be experienced. For the rest of Luzon, down to Visayas and Mindanao, partly cloudy to cloudy skies will prevail, only with isolated rain showers or thunderstorms.
While the present Habagat is categorized as weak, this, along with the Frontal System, has brought significant rainfall to some areas in Luzon. According to PAGASA Weather Forecaster Gener Quitlong, last week’s top three highest rainfall were recorded in these areas;
Batanes – 232 millimeters (mm) of rain in 24 hours – May 26, 2017
Calapan – 75.2 mm of rain in 24 hours – May 25, 2017
Casiguran – 76.2 mm of rain in 24 hours – May 24, 2017
