Fair weather to prevail until Friday -- Pagasa

MANILA -- Fair weather will continue in most parts of the country as the easterlies affect the eastern section of the country, the Philippine Atmospheric Geophysical and Astronomical Services Administration (Pagasa) said on Thursday.

Pagasa weather forecaster Aldczar Aurelio said that for the next two days, most parts of the country will remain to have good weather condition.

Aside from possible afternoon or evening rains due to localized thunderstorms or convections, he said that the whole country will continue to experience sunny to partly cloudy skies until Friday.

He added that Filipinos can now expect warmer days ahead as the state weather bureau officially declared the onset of the dry or summer season on Wednesday.

Aurelio said the “cold” northeast monsoon has ended and that the easterlies or warm winds from the Pacific Ocean are now affecting the country.

He said the termination of the northeast monsoon was the agency’s primary indicator of the onset of summer.

The northeast monsoon or “hanging amihan” is the cold wind from Siberia that blows into the country, usually from mid-October until March.

Aurelio said they have observed that the northeast monsoon stopped blowing into the country since early this week.

During summer months, Aurelio said the easterlies and the high-pressure area (HPA), which is the opposite of a low pressure area (LPA), will be the dominant weather systems in the country.

He noted that the North Pacific HPA, which is a weather system consisting of warm air circulating over the Pacific Ocean, is the one that blocks the entry of the northeast monsoon towards the country.

He said this North Pacific system would become more active during these times of the year.

On Tuesday, Aurelio said the agency has already monitored the establishment of a ridge of an HPA over the north Pacific Ocean, near south of Japan.

With the presence of a ridge of the North Pacific HPA that extended to north of the country, Aurelio noted that wind pattern shifted its direction from northeasterly to easterly.

“And this shift in wind pattern signifies the start of warmer days,” he explained.

Aurelio noted that both the HPA and the easterlies will bring high temperatures and good weather conditions to the country in the coming days.

With the onset of summer, Aurelio said temperatures in the country could climb up to 37 degrees Celsius in the coming days.

However, he noted that passing rains, especially in the afternoon or evening, is still possible due to localized thunderstorms or convections.

Aurelio said the dry or summer season in the country usually lasts until middle of June.

Temperature

Meanwhile, Metro Manila’s temperature has already sizzled to 34.2 degrees Celsius Wednesday afternoon.

So far, Aurelio said this was the hottest temperature recorded in Metro Manila this year.

He said the maximum temperature was monitored around 1:50 p.m. at the Pagasa’s Science Garden in Diliman, Quezon City.

He said this latest reading surpassed the previous high of 33.8 degrees Celsius, which was recorded on March 19.

For Thursday, temperature will range to 23-33 degrees Celsius in Metro Manila.

He said the hottest temperature in the country so far for this year was recorded in Subic, Zambales at 36.1 degrees Celsius last March 21.

Based on the Pagasa’s climatological record, the hottest temperature in Metro Manila was recorded on May 14, 1987 at 38.5 degrees Celsius.

The hottest temperature ever recorded in the country was in Tuguegarao, Cagayan at 42.2 degrees Celsius on May 11, 1969.

‘LPA’

Aurelio said Pagasa spotted a new cloud cluster over the Pacific Ocean that is moving towards the country.

The Japan Meteorological Agency (JMA) has already categorized the cloud cluster as a low pressure area (LPA).

However, Aurelio said that based from the agency’s criteria, it is just a cloud cluster and it has a slim chance of becoming an LPA.

Citing Pagasa’s numerical models, he added that it also has a slim chance of entering the country and is projected to dissipate in the next few days.

In its advisory, Pagasa said that the entire archipelago will have partly cloudy to cloudy skies with isolated rainshowers or thunderstorms mostly over the eastern section.

It added that moderate to occasionally strong winds from the east will prevail over the eastern section of the country and the coastal waters along this area will be moderate to occasionally rough.

Elsewhere, winds will be light to moderate blowing from the east with slight to moderate seas. (PNA)
