MANILA, Philippines – Tropical cyclone wind signal (TCWS) number 1 is raised over the province of Batanes and the Babuyan group of islands as severe tropical storm (STS) Hanna (international name Lekima) intensifies while moving northwest.

Under such condition, winds of 30 kph to 60 kph may be expected in at least 36 hours or intermittent rains may be expected within 36 hours, according to state weather service PAGASA.

As of 4:00 AM Wednesday (August 7), the center of STS Hanna was located at 610 km East of Basco, Batanes. It is moving west northwest at a speed of 10kph with sustained winds of 110 kph and gustiness of up to 135 kph.

STS Hanna continues to enhance the southwest monsoon which is expected to bring moderate to heavy rains over the northern portions of Palawan including Calamian and Cuyo Islands), Occidental Mindoro, Oriental Mindoro, Romblon, Zambales, Bataan, Aklan, and Antique.

Meanwhile, cloudy skies with scattered rain showers and thunderstorms will be experienced over Metro Manila, the rest of Luzon, Central Visayas and Western Visayas.

These areas were identified as highly or very highly susceptible to floods and rain-induced landslides thus residents are advised to take precautionary measures and continue monitoring for updates about the weather conditions from PAGASA.

STS Hanna is less likely to make landfall in any part of the country.

Fisherfolks with small sea vessels are advised not to venture out over the seaboards of areas under TCWS No. 1 as well as the seaboards of Luzon and Visayas, and the northern and eastern seaboards of Mindanao due to potentially rough sea conditions.

TS Auring slightly weakens as it moves northwestward

MANILA, Philippines — Tropical Storm Auring is now bringing light to moderate with at times heavy rains on Saturday over Caraga and Eastern Visayas. The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) said in its 5:00 PM weather update that heavy rains will be felt until Saturday evening.

Moderate to heavy rains, on the other hand, will be felt over Dinagat Islands, Surigao del Norte, and Eastern Visayas. Light to moderate with at times heavy rains over Northern Mindanao, Bicol Region, Mimaropa, Quezon, and the rest of Visayas and Caraga on Sunday (February 21).

Light to moderate with at times heavy rains will be expected over Bicol Region, Mimaropa, Western Visayas, Cagayan, Isabela, Aurora, and the southern portion of Quezon due to the combined effects of the weather disturbance and the Shear Line until Monday.

PAGASA said that under these conditions, scattered to widespread flooding (including flash floods) and rain-induced landslides are likely during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards as identified in hazard maps.

Adjacent or nearby areas may also experience flooding in the absence of such rainfall occurrence due to surface runoff or swelling of river channels. PAGASA Regional Services Divisions may issue local thunderstorm/rainfall advisories and heavy rainfall warnings while the Hydrometeorology Division and River Basin Flood Forecasting and Warning Centers may issue General Flood Advisories and Basin Flood Bulletins as appropriate, the state weather bureau said.

PAGASA added that in the next 24 hours, “the combined effects of the surge of the Northeast Monsoon and Tropical Storm Auring will bring strong to gale-force winds over the areas where Tropical Cyclone Wind Signal (TCWS) #1 is in effect, as well as over the rest of Visayas, Bicol Region, Calabarzon, and Mindoro Provinces, Marinduque, Romblon, and the northern portion of Palawan (including Calamian, Cuyo, and Kalayaan Islands). A strong breeze to near-gale conditions is also likely over the rest of Luzon.

The weather station also said that “rough to high seas (2.8 to 6.0 m) will be experienced over the seaboards of areas under TCWS in the next 24 hours.”

Rough to very rough seas (2.8 to 5.0 m) will prevail over the eastern and southern seaboards of Southern Luzon and the remaining seaboards of Visayas. Rough seas (2.5 to 4.0 m) will prevail over the northern and western seaboards of Mindanao and the remaining seaboards of Luzon. Sea travel is risky for all types of sea vessels over these waters, the advisory said.

Pagasa also warned that moderate to rough seas (1.2 to 3.0 m) will be experienced over the remaining seaboards of the country. Mariners of small sea crafts are advised to take precautionary measures when venturing out to sea. Inexperienced mariners should avoid navigating in these conditions.

TS Auring is forecast to continue moving generally northwestward throughout the forecast period. Its center is forecast to make landfall over the Dinagat-Homonhon-Leyte area on Sunday evening or Monday early morning then cross Visayas and Mimaropa, PAGASA added.

TS Auring is more likely to weaken to tropical depression before it makes landfall over Caraga. It will likely further weaken to Low Pressure Area by Monday due to significant terrain interaction and persistent vertical wind shear during this passage over the archipelago, the weather bureau said.

Wind signals lifted as ‘Ulysses’ weakens, moves to exit PAR

Marje Pelayo   •   November 13, 2020

MANILA, Philippines – The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) announced Friday (November 13) that no tropical cyclone wind signals remain in effect following the onslaught of Typhoon Ulysses.

Based on PAGASA’s 5:00 AM bulletin, the weather disturbance has weakened into a severe tropical storm (STS) while moving away from the country.

As of 3:00 AM, the center of STS Ulysses was estimated at 405 km West of Iba, Zambales with maximum sustained winds of 110 km/h near the center and gustiness of up to 135 km/h. It is moving Westward at 20 km/h and is expected to exit the Philippine Area of Responsibility (PAR) this morning or afternoon.

Based on PAGASA’s forecast, the combined effects of STS Ulysses and the surge of the Northeast Monsoon will continue to bring the following hazards in several areas of Luzon:

Gusty weather conditions

  • Batanes, Babuyan Islands, Cordillera Administrative Region, Ilocos Region, Zambales, Bataan, and northern Occidental Mindoro including Lubang Island.

Moderate to heavy with at times intense rains 

  • Batanes, Babuyan Islands, northern and eastern portions of mainland Cagayan, eastern portion of Isabela, Aurora, Nueva Vizcaya, Quirino, and Apayao. 

Light to moderate with at times heavy rains 

  • Ilocos Region, the rest of Cordillera Administrative Region, the rest of Cagayan Valley, the northern portion of Quezon including Polillo Islands, Zambales, and Bataan.

Generally, the tail-end of the frontal system will bring Cloudy skies with scattered rainshowers and thunderstorms over Cordillera Administrative Region and Cagayan Valley.

Meanwhile, the Northeast Monsoon will cause Partly cloudy to cloudy skies with isolated light rains over the entire Ilocos Region.

Metro Manila and the rest of the country, PAGASA said, will have a generally fair weather with at times partly cloudy to cloudy skies with isolated rainshowers due to localized thunderstorms.

Goni intensifies into severe tropical storm while moving westward

Maris Federez   •   October 29, 2020

MANILA, Philippines — Tropical Storm Goni has rapidly intensified into a severe tropical storm (STS) while moving westward at 10 km/h, the Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) said Thursday.

The center of STS Goni was estimated at 1,545 kilometers East of Central Luzon outside the Philippine Area of Responsibility (PAR) 16.6°North ,136.6°East, based on all available data.

The state weather bureau said STS Goni packed a maximum sustained winds of 95 km/h near the center and gustiness of up to 115 km/h.

Once it enters the PAR, Goni will be renamed Rolly, PAGASA said.

It added that STS Goni was forecast to intensify into a typhoon within 24 hours and will continue to intensify while moving over the Philippine Sea.

State meteorologists said Goni may bring heavy rains over the eastern sections of Central and Southern Luzon either by Friday or the weekend as it moves closer.

Tropical Cyclone Wind Signal (TCWS) No. 1 may be raised over some provinces in the Bicol Region and in Northern Samar by Friday evening. —/mbmf
