MANILA, Philippines — Tropical cyclone ‘Rolly’ (International name Goni) has entered the Philippine Area of Responsibility (PAR) and has rapidly intensified into a typhoon, according to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA).

It may continuously intensify over the Philippine Sea and is likely to make landfall at peak intensity of 165 to 185 kilometers per hour.

PAGASA said, in anticipation of the arrival of strong breeze to near-gale conditions due to the typhoon, tropical cyclone wind signal (TCWS) No.1 may be raised over several provinces in the Bicol Region today. 

Given that it is likely for this typhoon to continue intensifying prior to landfall, the highest possible TCWS that will be raised throughout its passage will be TCWS No.3 or TCWS No.4 associated with destructive to very destructive typhoon-force winds.

Thus, the public especially in areas though the typhoon path to take precautionary measures and constantly monitor updates for its development.

MANILA, Philippines – A low pressure area (LPA) has entered the Philippine area of responsibility (PAR) and is expected to bring rains over some parts of Luzon and the Visayas.

As of 3:00 AM Tuesday (December 1), the LPA is located at 375 km East of Legazpi City, Albay.

PAGASA sees possible ‘back-to-back’ La Niña

Marje Pelayo   •   November 30, 2020

MANILA, Philippines — The country has faced some of the strongest typhoons in history this year.

According to the Philippine Atmospheric, Geophysical and Astronomical Services Administration (PAGASA), this can also be associated with the prevailing episode of La Niña phenomenon, a weather condition where above normal rains are experienced in the country.

The onset of  La Niña in the country started since mid of this year but the state weather agency announced it is likely to extend until next year.

If this happens, PAGASA said, the country will likely experience a ‘back-to-back’  La Niña where the phenomenon prevails for two consecutive years.

“Most models show further strengthening ng  La Niña in November, December, January, and will likely to continue through March, April, and May 2021,” said Anna Solis, PAGASA’s chief of Climate Monitoring and Prediction Section.

“So kung ito ang ipa-follow natin, during the past 15 years baka magkaroon ng ‘back-to-back’  La Niña,” Solis said.

Based on PAGASA’s data, six episodes of ‘back-to-back’  La Niña have been recorded in the country since 2017, the worst one was in 2010 to 2011. MNP (with reports from Rey Pelayo)

MANILA, Philippines — The Philippine Atmospheric, Geophysical and Astronomical Services Administration  (PAGASA) said it is decommissioning four tropical cyclone names this year.

PAGASA decommissions or removes names from list of tropical cyclones when they are particularly destructive, specifically if it caused more than P1 billion worth of damage or claimed at least 300 lives.

This year, the following names of tropical cyclones that will be removed due to their corresponding accumulated amount of damage caused to the country are:

  • ‘Ambo’ (International Name Vongfong) – P1.57 billion
  • ‘Quinta’ (International Name Molave) – P4.22 billion
  • ‘Rolly’ (International Name Goni) – P17.6 billion
  • ‘Ulysses’ (International Name Vamco) – P18.62 billion

Overall, the four cyclones caused a total of P42.09 billion worth of damage to the country’s infrastructure and agriculture according to government records.

After decommissioning, PAGASA will replace the names with new ones to prevent psychological relapse or to prevent the victims from recalling the traumatic experiences the strong cyclones caused to them. MNP (with inputs from Rey Pelayo)
