Auring weakens into tropical depression

Maris Federez   •   February 22, 2021   •   369

The Philippine Atmospheric Geophysical and Astronomical Services Administration (PAGASA) has lowered the category of Auring into a Tropical Depression as it is forecast to continue moving generally northwestward in the next 24 hours, according to the weather bureau’s 11:00 pm update.

On the forecast track and its probability cone, the tropical depression may initially make landfall over the Dinagat Islands-Eastern Samar (southern portion including Homonhon Island)-Leyte area in the next 6 to 12 hours.

The state weather center said there is an increasing likelihood that Auring will further weaken before it makes landfall due to persistent high vertical wind shear associated with the surge of the Northeast Monsoon.

Post-landfall, Auring is forecast to weaken considerably due to significant terrain interaction and the increasing wind shear, leading to deterioration into a remnant low within 24 hours, possibly sooner.

As of 10:00 pm on Sunday, the center of Tropical Depression Auring was estimated based on all available data at 210 km East of Surigao City, Surigao del Norte (09.9 °N, 127.4 °E ), and is moving West Northwestward at 15 km/h with maximum sustained winds of 55 km/h near the center and gustiness of up to 70 km/h.

Tropical Cyclone Wind Signal (TCWS) #1 is hoisted over the following areas.

Luzon:

  • Sorsogon
  • Masbate including Ticao and Burias Islands
  • Albay
  • Catanduanes
  • Camarines Sur (Caramoan, Presentacion, Sagnay, Buhi, Iriga City, Nabua, Bato, Balatan)

Visayas:

  • Northern Samar
  • Eastern Samar
  • Samar
  • Biliran
  • Leyte

  • Agusan del Sur (Bayugan City, Prosperidad, Sibagat)
  • Misamis Oriental (Gingoog City, Magsaysay, Medina, Talisayan, Claveria, Balingasag, Lagonglong, Balingoan, Kinoguitan, Sugbongcogon, Binuangan, Salay)
  • Camiguin

The state weather center also said that in the next 24 hours, the combined effects of the Northeast Monsoon and Auring will bring strong breeze to near-gale conditions with occasionally higher gusts over the areas where TCWS #1 is in effect, as well as over the southern portion of Aurora, Quezon, Marinduque, Romblon, Oriental Mindoro, Cuyo Islands, Cagayancillo Islands, and the rest of Visayas and Bicol Region.

PAGASA advisory added that rough seas will be experienced over the seaboards of areas under TCWS #1 (2.5 to 4.0 m), the eastern seaboard of Central Luzon, the eastern seaboard of Southern Luzon not under any TCWS (2.5 to 3.5 m), the southern seaboard of Luzon and the remaining seaboards of Visayas (2.5 to 3.0 m). Sea travel is risky especially for those using small seacrafts.

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

Tropical Depression Crising forecast to weaken within 24 hours

MANILA, Philippines — Tropical depression Crising is expected to weaken in the next 24 hours, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) latest bulletin Friday (May 14).

Based on PAGASA’s forecast track, TD Crising will continue moving westward or west northwestward and emerge over the Sulu Sea in the next 6 to 12 hours.

Currently, the weather disturbance is still affecting most parts of Mindanao.

Specifically, light to moderate with at times heavy rains prevail over Zamboanga Peninsula, Davao Oriental, Davao de Oro, Davao del Norte, Davao City, Davao del Sur, Cotabato, Maguindanao, Bukidnon, Lanao del Norte, Lanao del Sur, and Misamis Occidental.

Residents in the said areas are reminded that isolated flash flooding and rain-induced landslides are possible during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards.

Strong breeze conditions are likely over the localities where Tropical Cyclone Wind Signal (TCWS) Number 1 is in effect, especially in the coastal and mountainous areas of these localities.

These areas include:

Visayas

The southeastern portion of Negros Oriental (Dumaguete City, Valencia, Sibulan, Santa Catalina, Siaton, Zamboanguita, Dauin, Bacong) and Siquijor

Mindanao

The western portion of Misamis Oriental (Jasaan, Villanueva, Tagoloan, Cagayan de Oro City, Opol, City of El Salvador, Alubijid, Manticao, Lugait, Naawan, Initao, Libertad, Gitagum, Laguindingan), the western portion of Bukidnon (Manolo Fortich, Sumilao, Pangantucan, Kalilangan, Talakag, Baungon, Libona), the northwestern portion of Cotabato (Banisilan, Alamada), the northern portion of Maguindanao (Matanog, Barira, Buldon), Lanao del Sur, Lanao del Norte, Misamis Occidental, the northeastern portion of Zamboanga del Sur (Midsalip, Sominot, Dumingag, Molave, Mahayag, Josefina, Tambulig, Ramon Magsaysay, Aurora, Tukuran, Labangan), and the northeastern portion of Zamboanga del Norte (Sergio Osmeña Sr., Katipunan, Pres. Manuel A. Roxas, Jose Dalman, Manukan, Dipolog City, Polanco, Piñan, Mutia, Dapitan City, Sibutad, Rizal, La Libertad)

PAGASA said tropical depression Crising will cause moderate to rough seas over the seaboards of areas under TCWS #1 in the next 24 hours.

Thus, mariners of small sea vessels are advised not to venture out over these waters and inexperienced mariners of these vessels should avoid navigating in these conditions.

TD Crising aims for Surigao del Sur-Davao Oriental area tonight or Friday — PAGASA

Marje Pelayo   •   May 13, 2021

MANILA, Philippines – The Low Pressure Area (LPA) over the Philippine sea east of Davao City has developed into tropical depression ‘Crising’ at 2:00 AM Thursday (May 13), based in the latest weather bulletin from the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

On the forecast track, TD Crising is likely to make landfall over Surigao del Sur-Davao Oriental area between tonight and Friday (May 14) early morning.

Although a slight intensification remains likely, TD Crising is forecast to remain as a tropical depression prior to landfall.

Throughout tomorrow, the tropical depression is expected to traverse the rugged landmass of Mindanao and may emerge over the Sulu Sea on Saturday (May 15) early morning.

It is seen to weaken into a remnant low on Sunday (May 16) early morning.

On Thursday, the state weather agency PAGASA hoisted tropical cyclone wind signal (TWCS) number 1 over the areas of Surigao del Sur, Davao Oriental, Davao de Oro, and the eastern portion of Agusan del Sur (Prosperidad, San Francisco, Rosario, Bunawan, Trento, Santa Josefa, Veruela).

This means, winds of 30 km/h to 60 km/h may be expected in at least 36 hours or intermittent rains may be expected within 36 hours in the affected areas between today and Friday (May 14).

Also under these conditions, isolated to scattered flooding and flash floods as well as rain-induced landslides are possible during heavy or prolonged rainfall.

PAGASA also warned that strong breeze to near gale conditions is likely over the localities covered by TWCS No.1 especially in the coastal and mountainous areas of these localities.

In the next 24 hours, moderate to rough seas will be experienced over the eastern seaboard of Mindanao due to the impact of TD Crising.

Mariners of small seacrafts are advised not to venture out over these waters.

Inexperienced mariners of these vessels should avoid navigating in these conditions.

PAGASA monitors low pressure area east of Davao City

Marje Pelayo   •   May 12, 2021

MANILA, Philippines – The Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA) is monitoring a low pressure area (LPA) brewing near the southern section of the country.

As of 10:00 AM Wednesday (May 12), the LPA was estimated at 595 kilometers East of Davao City.

It is forecast to move generally westward or west-northwestward towards Mindanao but is less likely to develop into a tropical depression in the next 24 hours.

PAGASA said the trough of LPA will bring light to moderate with at times heavy rains over Surigao del Sur and Davao Oriental in the next 24 hours.

Under these conditions, isolated to scattered 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.

The public and disaster risk reduction and management offices concerned are advised to take appropriate measures and monitor regular updates on this weather disturbance through the agency’s official website.
