"Ulysses" re-intensified from a severe tropical storm to a typhoon before leaving the Philippine Area of Responsibility Friday.
The Philippine Atmospheric, Geophysical, and Astronomical Services Administration said fair weather could now be expected in the coming days as no weather disturbance has been monitored near the country.
Consecutive tropical cyclones lashed the Philippines in a span of two weeks, causing massive destruction amid the COVID-19 pandemic.
PAGASA said Ulysses left the PAR Friday morning and was last located 500 kilometers west of Iba, Zambales.
Ulysses briefly weakened into a severe tropical storm before dawn Friday but re-intensified into a typhoon at 8 a.m. with maximum sustained winds of 120 kilometers per hour near the center and gustiness of up to 150 kph and moving west-northwest at 10 kph towards central Vietnam.
The State weather bureau said Ulysses is likely to maintain its strength in the next 12 hours and is expected to gradually weaken due to "increasingly unfavorable conditions" caused by the surge of the northeast monsoon or "amihan."
Ulysses left a trail of destruction in Luzon, including areas that have yet to fully recover from super typhoon "Rolly," after making three landfalls in Quezon Wednesday night and early Thursday morning.
PAGASA said the typhoon made its first landfall near Patnanungan 10:30 p.m. Wednesday, followed by a second landfall near Burdeos at 11:20 p.m., then near Gen. Nakar at 1:30 a.m. Thursday.
It slightly weakened while crossing Central Luzon Thursday due to its interaction with the Sierra Madre and Zambales mountains.
Although outside PAR and not directly affecting the country, PAGASA said the typhoon and the surge of amihan will continue to bring gusty conditions over Batanes, Babuyan Islands, Cordillera Administrative Region, Ilocos region, Zambales, and Bataan.
Moderate to heavy rains will still be experienced over Batanes and Babuyan Islands Friday while light to moderate with at times heavy rains may prevail over the rest of Cagayan Valley, CAR, Ilocos Norte, and Aurora.
Flooding, including flash floods, rain-induced landslides, and sediment-laden streamflows such as lahar could also occur during heavy or prolonged rainfall especially in areas that are highly or very highly susceptible to these hazards and or those that received significant antecedent rainfall, PAGASA added.
Meanwhile, the combined effects of Ulysses and the surge of the northeast monsoon will bring rough to very rough seas over the seaboards of Batanes, Babuyan Islands, Ilocos Norte, Ilocos Sur, La Union, Pangasinan, and Zambales, the northern seaboard of mainland Cagayan, and the western seaboards of Bataan, Batangas, Occidental Mindoro (including Lubang Island), and Palawan (including Calamian and Kalayaan Islands).
Ulysses is the 21st tropical cyclone in the country this year and the third this month following tropical storm "Tonyo" and Rolly – already above the annual average of 20 tropical cyclones.
PAGASA said more rains are expected in the coming months due to the onset of the La Niña weather phenomenon.
