The country remains storms-free as the new week sets in.

According to PAGASA Weather Forecaster Samuel Duran, no weather disturbance is expected in the next three days.

Today, Ridge of a High Pressure Area extends over Northern Luzon, while Easterlies affect the rest of the country. These will bring partly cloudy to cloudy skies or a generally fair weather will prevail in the entire country only with chances of isolated rain showers or localized thunderstorms in the latter part of the day.

 
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.

 
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
 
 

This weekend, remember to bring your umbrellas as you make your “huling hirit sa tag-init,” because the prevailing Southwest Monsoon or Habagat brings possibilities of rains. According to PAGASA Weather Forecaster Loriedin dela Cruz, the habagat is in effect in the western section of Luzon and Visayas.

 

With its warm and moist characteristics, the habagat will bring cloudy skies with light to moderate rain showers and thunderstorms to the regions of Ilocos, Cordillera, MIMAROPA, CALABARZON, Bicol, Western Visayas and the provinces of Batanes, Cagayan, Zambales and Bataan. In the remaining parts of the country including Metro Manila, partly cloudy to cloudy skies prevails only with isolated rain showers or thunderstorms.

Dela Cruz adds that no weather disturbance is expected to affect the country in the next two days.

Generally fair weather prevails today. According to PAGASA Weather Forecaster Chris Perez, partly cloudy to cloudy skies will affect the archipelago only with isolated rain showers or thunderstorms mostly in the afternoon or evening as Easterlies, or warm and humid air from the Pacific Ocean, dominates.
 

 
Perez said, warm and humid weather is still expected today and heat index can soar up to 39.6 degrees Celsius.
 

 
If this good weather continues, we can enjoy various festivals this month.
 
In the Philippines, each city or municipality has a local festival of its own. The celebration includes the feast of the town’s patron saint, as well as an abundance of local products. Some of the festivals celebrated in May are the Bawang Festival of Ilocos province, the Hundred Islands Festival in Pangasinan, the Pahiyas Festival in Quezon, and the Flores de Mayo in almost every town.

A new weather disturbance is forecast to enter the Philippine Area of Responsibility (PAR) this week.
 

 
According to PAGASA, the Low Pressure Area (LPA) previously spotted outside PAR has developed into a tropical depression. As of 10 AM, it was located 1,540 kilometers east of Mindanao. It has maximum sustained winds of 45 kph and gustiness of 60 kph, slowly moving at a west-northwest direction.
According to PAGASA Weather Forecaster Loriedin dela Cruz, the LPA can possibly enter PAR within 24 hours. If this happens, the tropical depression will be given the local name “Dante,” this month’s second tropical cyclone.
 

Today, Easterlies or warm and humid air from the Pacific Ocean prevail in the eastern sections of the country. This weather system will bring partly cloudy to cloudy skies or generally fair weather in the entire archipelago except for isolated rain showers or thunderstorms. Humid weather is still expected to prevail.
 

Have you been complaining about the humid weather these past days? Well, the surge of the Northeast Monsoon may give you a break.
 
Yesterday, PAGASA recorded an air temperature of 36.5°C in Sinait, Ilocos Sur. With the humid weather, heat indices also continue to increase. Heat index refers to temperature obtained from the high air temperature and relative humidity. It also describes how the human body perceives the heat or the warm weather.
 

 

 
PAGASA Weather Forecaster Chris Perez reminded the public through an interview with Panahon TV that when the computed heat index value is between 30-40°Celsius, a person may experience exhaustion and stroke.
 

 
However, Amihan has slightly intensified today and is now affecting Northern and Central Luzon. This Tuesday, cloudy skies with light to moderate rains and isolated thunderstorms will prevail in the regions of Caraga and Davao. Cloudy skies with isolated light rains are also expected in the regions of Cagayan Valley and Cordillera, and the provinces of Aurora and Quezon. Partly cloudy to cloudy skies with isolated light rains will be experienced in the Ilocos Region and the rest of Central Luzon. Partly cloudy to cloudy skies with isolated rain showers or thunderstorms will prevail in Metro Manila and the rest of the country.
 
Strong to gale force winds associated with the surge of the Amihan are causing rough to very rough seas in the seaboards below. Fishing boats and other small seacraft are advised not to venture out while larger sea vessels are alerted against big waves.
 

 

PAGASA has yet to declare the start of the Hot and Dry Season but the heat has become increasingly intense in some parts of the country.
Yesterday, PAGASA recorded a scorching 36°C in Cabanatuan.
 

 
Today, a maximum of 34°C air temperature is expected in Metro Manila. For Baguio City, it will be between 16-26°C, 26-32°C in Iloilo and a maximum of 34°C in Zamboanga City.
 
While temperatures are expected to spike, the Northeast Monsoon in the Northern Luzon is still bringing cloudy skies with isolated light rains in Cagayan Valley Region. Partly cloudy to cloudy skies with isolated light rains will be experienced in the regions of Cordillera and Ilocos.  Caused by the warm and humid air from the Pacific called Easterlies, partly cloudy to cloudy skies with isolated rain showers or thunderstorms will prevail in Metro Manila and the rest of the archipelago.
 
Despite the warm temperatures, gale warning is hoisted in the seaboards of Northern Luzon where sea travel may be risky due to rough to very rough sea conditions.
 

 

 
Temperatures are beginning to rise in most parts of the country but the Northeast Monsoon, locally known as Amihan, has yet to end its dominance in Luzon.
 

 
This midweek Wednesday, Amihan has again intensified, affecting Northern and Central Luzon. As an effect, cloudy skies with light rains are expected in the Batanes Group of Islands. It will also bring partly cloudy to cloudy skies to the Ilocos Region, Cordillera, Central Luzon and rest of Cagayan Valley. In Metro Manila, the rest of Luzon, down to Visayas and Mindanao, generally fair weather will prevail only with chances of isolated rain showers or thunderstorms.
 
Despite the increasing temperatures in the country, PAGASA has yet to declare the commencement of the Hot and Dry season.
 
“’Yung warm and humid air ng Easterlies ang isa sa mga pangunahing characteristics para mag-declare po tayo ng tag-init. Hindi lang tayo makapag-terminate ng Amihan sa kadahilanang bumabalik ito.” (The warm and humid characteristics of Easterlies are one the factors before declaring the Hot and Dry Season. We can’t still announce it because Amihan has yet to be terminated.)
 

 It can be recalled that PAGASA announced the termination of Amihan on March 18 last year, signaling the start of the Hot and Dry Season or tag-init.
