On the last day of this year, the Philippine Atmospheric Geophysical and Astonomical Services Administration (PAGASA) continues to monitorTropical Storm Seniang with international name Jangmi. It was locatedat 245 kilometers south southeast of Cuyo, Palawan at 9:00 AM today.
It has weakened into a tropical depression with maximum sustained winds of 55 kilometers per hour.

With its continuous movement in a west-southwest direction at 13 kilometers per hour, Seniang is expected to leave the Philippine Area of Responsibility (PAR) on Friday, January 2, 2015.

Public Storm Warning Signal Number 1 is up over Palawan where winds of 30 to 60 kilometers per hour are expected. Residents are alerted against possible flash floods and landslides.

The combined effect of the northeast monsoon or amihan and the winds
associated with Seniang will bring rough to very rough sea conditions in the seaboards of Northern, Central and Southern Luzon and Visayas. Fishing boats and other small seacraft are still prohibited from venturing out into the mentioned seas.

Palawan will experience rains with gusty winds. Cloudy skies will dump light to moderate rain showers and thunderstorms over Visayas, Bicol Region and the provinces of Quezon, Mindoro and Marinduque. Metro Manila and the rest of Luzon will experience light rains, while Mindanao will have improved weather. Still, partly cloudy to cloudy skies with isolated rain showers or thunderstorms are expected.

PAGASA issues special weather outlook for New Year

Based on the outlook, rains will continue on the first day of 2015. Seniang may bring rains with gusty winds over Palawan, while the Bicol Region, CALABARZON, Western Visayas and the provinces of Mindoro, Marinduque and Romblon will have cloudy skies with light to moderate
rain showers and thunderstorms. Metro Manila and Central Luzon will be cloudy with light rains and the rest of the country will have a generally fair weather aside from the isolated cases of rain showers or thunderstorms.

Changes may still occur depending on the weather systems that will prevail within the PAR. All are advised to monitor updates.

Prior to making landfall, Seniang intensified into Tropical Storm category this morning with maximum sustained winds of 65 kph near the center and gustiness of up to 80 kph. The storm continues to move in a west-northwest direction at 11 kph.

PAGASA Weather Forecaster Jori Loiz says Seniang hit Baranggay Bakulin in Hinatuan, Surigao del Sur at 3:45 am today. The storm will move towards Agusan del Norte before traversing Bohol Sea, he added.

As it continues to cross the archipelago, more provinces in Visayas and Mindanao are placed under Public Storm Warning Signals:

Areas under Signal #2 will experience stormy weather whereas rains with gusty winds will be felt over the provinces under signal #1. Residents living near low-lying and mountainous areas are alerted against possible flashfloods and landslides.

Meanwhile, Cagayan Valley, Cordillera and Ilocos Regions, as well as Central Luzon, can expect cloudy skies with light rains. Metro Manila and the rest of Luzon will be partly cloudy to at times cloudy with isolated light rains.

PAGASA has also released gale warnings over the eastern seaboards of Luzon and Visayas, where rough to very rough sea conditions are expected due to the surge of the northeast monsoon and tropical storm Seniang. The latest weather bulletin also shows the possibility of ocean waves reaching up to 5 meters, making sea travel very risky also in the northern and eastern seaboards of Mindanao.

Residents of Palawan will be experiencing a stormy new year. Loiz states if the storm maintains its current speed and direction, it will exit the Philippine Area of Responsibility by January 1 or 2.

Before departing from the Philippine boundary, Ruby has intensified into Tropical Storm category with maximum sustained winds of 65 kph near the center and gustiness of about 80 kph. PAGASA weather forecaster Benison Estareja said that this because Ruby is within the vicinity of the West Philippines Sea–it’s increase in intensity due to the moisture it had gathered from the ocean.

Tropical storm Ruby was last located at 505 kilometers west southwest of Calapan City, Oriental Mindoro, moving at a speed of 20 kph. If it maintains its velocity, Ruby will exit the Philippine Area of Responsibility (PAR) tonight according to PAGASA weather forecaster Aldczar Aurelio. Because of its distance, it will have no direct effect on any part of the country, confirmed Estareja.

Cold Weather awaits

The northeast monsoon has found its way again to Northern Luzon. Cold weather with lights rains will be experienced mostly in Cagayan Valley, Cordillera and Ilocos Region.
Baguio City’s temperature will range from 15 to 23 degrees Celsius.

Meanwhile, with the intrusion of winds from the east, fair weather is expected over Metro Manila and the rest of the country. Partly cloudy to cloudy skies with isolated rain showers are possible in the afternoon or evening.

Top 3 places with highest amount of rainfall

During the passage of Ruby, areas in Southern Luzon has recorded the highest amount of rainfall.

Ruby continues to weaken as it traverses the landmass of Southern Luzon. With maximum sustained winds of 60 kph, Ruby is now downgraded to Tropical Depression, the lowest category of Tropical Cyclones.

PAGASA Weather Forecaster Glaiza Escullar said the weakeaning of Ruby is due to the friction between the landmass and the weather disturbance, and the intrusion of the northeast monsoon or amihan–cold and dry air mass that is not favorable to cyclone intensification.

Tropical Depression Ruby made its fifth landfall over Lubang Island at 5 AM today. Its first landfall was in Dolores, Eastern Samar last Saturday at past 9 PM. Its second landfall was in Cataingan, Masbate last Sunday morning. The third was in Torrijos, Masbate yesterday at 11:05 in the morning. Its fourth landfall was in Laiya, Batangas yesterday at 5:45 PM.

At 4 AM today, Ruby was located at 80 kilometers southwest of Ambulong, Tanuan City in Batangas, moving westward at 13 kph. (FOR REVISIONS PAG MAY LATEST LOCATION)

Escullar confirmed that if Ruby maintains its velocity, it is expected to exit the Philippine Area of Responsibility on Wednesday.

Public Storm Warning Signal

Areas included under Public Storm Warning Signal no. 1 will experience occasional rains with gusty winds.

Meanwhile, Public Storm Warning Signals elsewhere have been lifted.

Tuesday rainy weather

Apart from those under Public Storm Warning Signal no. 1, the rest of Central Luzon, Bicol Region and MIMAROPA will have cloudy skies with light to moderate rains and thunderstorms.

Because the amihan is now affecting Northern Luzon. cold weather and light rains are expected over Cagayan Valley, the Cordillera and Ilocos Regions.

Rainfall Data as Ruby crawl along PH islands.

Here is a list of areas that accumulated the highest rainfall during the passage of Ruby.

Natural disasters, particularly typhoons, have earned special attention and mention throughout our nation’s history because of the devastation they leave behind, causing immense losses to infrastructure, agriculture and human lives.

This year alone, several typhoons have left their mark on the public consciousness, including Tropical Storm Fung-Wong (local name: Mario), which caused severe flooding in Greater Luzon, including Metro Manila, affecting more than 118 thousand families.

Meanwhile, Typhoon Rammasun (local name:Glenda) crossed Southern Luzon in July with maximum winds of 150 kilometers per hour. It made its landfall in Albay, claiming more than one billion pesos worth of infrastructure and more than six billion pesos worth of agricultural products and facilities.

Luckily in October, when Super Typhoon Vongfong (local name: Ompong), tagged as the strongest typhoon that entered Philippine Area of Responsibility this year, packing maximum sustained winds of 215 kilometers per hour, it kept its distance from the country as it moved outside our boundary. Though Vongfong did not do damage to the Philippines, Japan was not able to evade the rage of the super typhoon. 31 people were injured, 90,000 households in Okinawa had to evacuate, and more than 400 flights were cancelled. It also knocked out power supply in Okinawa.

It seems that the names of the tropical cyclones are as unique as their characteristics and effects on the areas they have gone through. In the Philippines, PAGASA has a ready list of Filipino names for tropical cyclones.

Just as local names are important for easy communication among PAGASA, the media and the public, so are international names since these weather disturbances can affect more than one country. Through constant correspondence with other nations, we can gauge the cyclone’s track and projected effects—an important tool in increasing preparedness on both national and community levels.

How the naming process began

The areas where tropical cyclones are formed are divided into seven basins: North Atlantic Ocean, Northeastern and Northwestern Pacific Ocean (where the Philippines is located), Southwestern and Southeastern Indian Ocean, North Indian Ocean and Southwest Pacific Ocean.

According to the National Oceanic and Atmospheric Administration, Australian forecaster Clement Wragge introduced the use of proper names in naming cyclones in the late 19th century. When the Australian national government failed to establish the federal weather bureau and appoint Wragge as director, the forecaster took matters in his own hands and started naming cyclones after political figures whom he disliked and described as “causing great distress and wandering aimlessly about the Pacific.”

It took 40 years before the idea inspired George Stewart, a junior meteorologist in the United States to name Pacific tropical storms after his former girlfriends in his 1941 novel “Storm.”

It was in 1945 when the US armed services formally embraced the practice of using women’s names for typhoons in the Western Pacific. Eight years later, the US Weather Bureau finally adopted the use of women’s names for cyclones in the Northwest Pacific basin. It was in 1979 when men’s names were used.

Meanwhile, cyclones in the Southwest Indian Ocean started using names during the 1960s, while the North Indian Ocean cyclones were formally named in 2006.

According to the Weather Philippines Foundation, a new list of Asian names was contributed by all member nations of the World Meteorological Organization‘s (WMO) Typhoon Committee in January 1, 2000. These names are allocated to developing tropical storms by the Tokyo Typhoon Center of the Japan Meteorological Agency, and are arranged in alphabetical order of contributing countries. The majority of names includes flowers, animals, birds, trees, food and adjectives.

Currently, the Economic and Social Commission for Asia and the Pacific Typhoon Committee (ESCAP/WMO), which promotes the order and implementation of procedures required for minimizing the losses caused by typhoons, has 14 members: Cambodia; China; Democratic People’s Republic of Korea; Hong Kong, China; Japan; Lao People’s Democratic Republic; Macao, China; Malaysia; Philippines; Singapore; Thailand; Socialist Republic of Vietnam, and the United States of America.

Regardless of the year, international names are used per column. Below are the lists of names for developing tropical cyclones in the Northwest Pacific basin within a six-year time frame.

Retiring of Names

Tropical cyclone names are retired if they have caused significant damage and casualties in an area. A new list of names is discussed during the annual meeting of the WMO’s regional committee.
