November 2017 – PanahonTV

After a short break last week, the Northeast Monsoon is back and has further intensified.

Today, the Northeast Monsoon or Amihan brings cool breezes and rains in Northern and Central Luzon. Meanwhile, the Intertropical Convergence Zone (ITCZ) and Easterlies dampen Mindanao, and the eastern sections Southern Luzon and Visayas, respectively.

Today, Quezon, the Bicol Region, Eastern Visayas and Mindanao will have cloudy skies with scattered rain showers and thunderstorms. In Metro Manila, Ilocos Region, Cordillera, Cagayan Valley, and Central Luzon, partly cloudy to cloudy skies will be experienced with isolated light rains. In the rest of the country, partly cloudy to cloudy skies with isolated rain showers will prevail.

Gale warning is still raised in the northern seaboards of Northern Luzon. These include Batanes, Calayan, Babuyan, and the northern coasts of Cagayan and Ilocos Norte. Due to rough to very rough seas, fishing boats and other small seacraft are advised not to venture out while larger vessels are alerted against big waves.

Cooler Days Ahead
Temperatures continue to dip as the Northeast Monsoon, the cold and dry air from Siberia, intensifies. Yesterday, a chilling 16.6 degrees Celsius was recorded in Baguio City. In Tanay, Rizal 17 degrees Celsius was recorded, while the temperature dropped to 21 degrees Celsius in Infanta, Quezon. The surge of Amihan is expected in January and February.

Different weather systems prevail within the Philippine Area of Responsibility (PAR). The Tail-end of a Cold Front and Northeast Monsoon or Hanging Amihan are now dominant in the Northern Luzon while the Intertropical Convergence Zone (ITCZ) affects the entire Mindanao.

The Tail-end is the extended part of a frontal system, where cold and warm air masses meet. Meanwhile, Hanging Amihan is cold and dry air coming from the Mainland China or Siberia. The ITCZ, on the other hand, is the boundary of winds coming from the Northern and Southern Hemispheres. These weather systems are expected to bring rains in some parts of the archipelago on the last Sunday of November.

Mindanao, Eastern Visayas, Aurora, Cagayan, Isabela, Nueva Vizcaya and Quirino will experience cloudy skies with scattered rain showers and thunderstorms. Isolated light rains will affect Ilocos Region, Cordillera Administrative Region (CAR), Batanes and Babuyan Group of Islands. Metro Manila and the remaining parts of the country can expect generally fair weather apart from the isolated rain showers or thunderstorms mostly in the afternoon or evening.

Several seaboards in country are now placed under the gale warning, where fishing boats and other small sea craft are not allowed to sail due to rough to very rough sea condition. Wave height ranging from 2.8 to 4.5 meters may be experienced in Batanes, Calayan, Babuyan, Cagayan, Isabela, northern and western coast of Ilocos Norte, Aurora, Camarines provinces, eastern coast of Quezon including Polillo Islands, eastern coast of Albay, Catanduanes, eastern Samar and eastern section of Southern Leyte.

The Northeast Monsoon, or cold and dry air from Siberia is still affecting Extreme Northern Luzon where it brings lights rains. The rest of the country will experience humid weather due to the Easterlies, warm and humid air from the Pacific Ocean.

Today, Batanes and the Babuyan Group of Islands will have cloudy skies with light rains. In the Ilocos Region, Cordillera Administrative Region and the rest of Cagayan Valley, partly cloudy to cloudy skies will prevail with isolated light rains. For the rest of the country, generally fair weather will be experienced only with isolated rain showers mostly in the afternoon or evening.

Rough to very rough conditions are expected off the northern, eastern and western seaboards of Northern Luzon where wave height may reach up to 3.4 to 4.5 meters. Fishing boats and other small seacraft are advised not to venture out while larger sea vessels are alerted against big waves in Batanes, Calayan, Babuyan, the northern coast of Cagayan, Ilocos Norte, Ilocos Sur, La Union, Pangasinan, Isabela and the eastern coast of Cagayan.

La Niña Looms
Based on PAGASA’s 96th Climate Outlook Forum held yesterday, the La Niña Watch is still in effect.
La Nińa is characterized by unusually cool ocean surface temperatures in the Central and Eastern Equatorial Pacific (CEEP).

Since September 2017, cold ocean conditions persisted, indicating that La Niña is developing. According to PAGASA, the La Niña Advisory or the actual Weak La Niña phenomenon may begin next month, but is not expected to last beyond March 2018. During this event, above-normal rainfall in different parts of the country may occur. Impacts also include slightly warmer air temperatures, though the Amihan may bring surges of cold temperatures in the northern and eastern parts of Luzon.

The country may also experience a higher chance of tropical cyclone occurrences that may bring much rainfall during the remaining days of 2017 until the first quarter of 2018.

Three weather systems including the Northeast Monsoon, Tail-end of Cold Front and Intertropical Convergence Zone (ITCZ) are expected to affect the country. The Northeast Monsoon, locally known as Hanging Amihan, prevails in the Extreme Northern Luzon. Apart from the slightly colder weather, it will bring partly cloudy to cloudy skies with isolated light rains in the province of Batanes and the Babuyan Group of Islands.

The extension of the cold front, where the boundary of warm and cold air converge, is still expected to bring cloudy skies with scattered rains and thunderstorms in the provinces of Cagayan, Isabela, Aurora and Quezon. Residents should watch out for possible flooding in low-lying areas and landslides in mountainous zones.

The same weather condition is expected in the Autonomous Region in Muslim Mindanao (ARMM), South Cotabato, Cotabato, Sultan Kudarat, Sarangani and General Santos City (SOCCSKSARGEN). Meanwhile, Metro Manila and the rest of the country will have partly cloudy to cloudy skies with isolated rain showers or thunderstorms mostly in the latter part of the day.

No gale warning is up today but sea travelers in Luzon are advised to be cautious as moderate to rough sea conditions may prevail today. Slight to moderate seas will be experienced in Visayas and Mindanao, where coastal waters are favorable for sailing.

The Philippine National Police Anti-Cybercrime Group (PNP-ACG) warned trolls spreading forged information online.

Yesterday, Department of Education (DepEd) called on the public to be vigilant against fake news as it disowned posts circulating on social media regarding the supposed suspension of classes.

In an interview with PanahonTV, PNP-ACG Public Information Office Head Chief Inspector Jay Guillermo said that online misinformation is a violation of the Republic Act 10175.

Known as the Cybercrime Prevention Act of 2012, the law addresses crimes committed by means of computer systems, and focuses on the preemption, prevention, and prosecution of cybercrimes, among them offenses against confidentiality, integrity, and the availability of computer data and systems.

According to Guillermo, perpetrators could face six to 12 years of imprisonment and fine amounting to P60,000 to P120,000, depending on the effect of the online misinformation.

Stressing that the agency is capable of locating culprits, Guillermo however admitted that no one has been jailed in spreading misinformation online as no one has ever filed a formal complaint.

According to PAGASA Weather Forecaster Samuel Duran, no other weather disturbance is expected to enter or develop within the Philippine Area of Responsibility (PAR) within the next 2-3 days. However, three rain-inducing weather systems prevail including the Tail-end of a Cold Front, Trough of Low Pressure Area (LPA) and Northeast Monsoon.

The Tail-end of a Cold Front is the boundary of two different air masses, where the cold air mass dominates the warm air mass. When winds converge, convective clouds are formed, bringing rains in affected areas. In the next hours, cloudy skies with scattered rain showers and thunderstorms will prevail in the provinces of Cagayan, Isabela, Aurora and Quezon.

The same weather condition is expected in Mindanao due to the trough or extended part of an LPA. Meanwhile, Hanging Amihan will continue to bring isolated light rains in Batanes and the Babuyan Group of Islands. Metro Manila and the rest of the country will experience partly cloudy to cloudy skies with isolated rain showers or thunderstorms mostly in the afternoon or evening.

Sea travelers and fisherfolk are not advised to venture out into the northern seaboard of Northern Luzon, where gale warning remains hoisted. Batanes, Calayan, Babuyan, coasts of Cagayan and Ilocos Norte will have rough to very rough sea conditions with wave height ranging 3.1 to 4.5 meters.

Apart from the light rains and bumpy coastal waters, Amihan is also responsible for the slight drop in temperatures, mostly in the northern parts of Luzon. Here are the lowest temperatures recorded yesterday, November 20, 2017.

Baguio City – 17.0°C
Itbayat and Basco, Batanes – 21.0°C
Tanay, Rizal – 21.3°C

Baguio City – 17.0°C
Itabayat and Basco, Batanes – 21.0°C
Tanay, Rizal – 21.3°C

Three weather systems are dominant in the Philippine Area of Responsibility (PAR) today. These include Tail-end of a Cold Front bringing scattered rains in the eastern section of Northern and Central Luzon; the Northeast Monsoon dampening Extreme Northern Luzon; and an extension of a Low Pressure Area (LPA) causing rains in southern parts of Mindanao.
Today, Cagayan, Isabela, Quirino, Nueva Vizcaya, Aurora and Quezon will have cloudy skies with scattered rains and thunderstorms. In Davao Region and Soccsksargen, cloudy skies with scattered rains and thunderstorms will be experienced. Meanwhile, partly cloudy to cloudy skies with isolated light rains will prevail in Batanes and the Babuyan Islands. In the rest of the country, including Metro Manila, generally fair weather will start the week. Partly cloudy to cloudy skies will prevail only with isolated rain showers or localized thunderstorms.
Rough to very sea condition is expected in the northern seaboards of Northern Luzon. These include Batanes, Calayan, Babuyan, Cagayan and Ilocos Norte. According to PAGASA, fishing boats and other small seacraft are prohibited from venturing while larger sea vessels are alerted against wave height that can reach up to 4.5 meters.

Colder Days Ahead
Temperatures are dropping as the Northeast Monsoon or Amihan continues to prevail in the Extreme Northern Luzon.
Yesterday, a chilling 17 degrees Celsius was recorded in Baguio City while temperatures dropped to 17.5 in Tanay, Rizal.
The Amihan is expected to peak in January and February.

The Tropical Depression Tino has exited the Philippine Area of Responsibility (PAR).

At 3:00 AM, the weather disturbance with international name Kirogi was spotted at 275 kilometers west of Pag-asa Island, Palawan. It has maximum winds of 60 kilometers per hour (kph), gustiness of 80 kph, moving westward at 20 kph. Last week, Palawan was placed under tropical cyclone warning signal as the cyclone persisted. No immediate damage was reported.

The Tail-end of a Cold Front continues to bring rains in the eastern section of Northern Luzon, while the Northeast Monsoon dampens the Extreme Northern Luzon.

Today, Cagayan, Isabela, Aurora and Quezon will have cloudy skies with scattered rains and thunderstorms. In the Ilocos Region, Cordillera and Batanes, partly cloudy to cloudy skies with isolated light rains will be experienced. In the rest of the country including Metro Manila, fair weather will prevail only with isolated rain showers.
