MANILA, Philippines – Super Typhoon Rosal (Champi) weakened further while moving east of Batanes before dawn on Thursday, October 22, but it remains a powerful tropical cyclone.

In a bulletin issued at 5 am on Thursday, the Philippine Atmospheric, Geophysical, and Astronomical Services Administration (PAGASA) said Rosal’s maximum sustained winds slightly decreased from 205 kilometers per hour to 195 km/h. Its gustiness eased from 250 km/h to 240 km/h.

At its peak, Rosal had maximum sustained winds of 215 km/h. PAGASA’s latest forecast shows it is likely to be downgraded to a typhoon on Thursday.

As of 4 am, Rosal was already 495 kilometers east of Basco, Batanes, moving northwest at 20 km/h.

It remains unlikely to make landfall in the Philippines, but it will be closest to extreme Northern Luzon between Thursday afternoon and Friday morning, October 23.

On Thursday, moderate to intense rain may hit at least three provinces in Northern Luzon. Here is the weather bureau’s updated rainfall outlook for the next 48 hours, also released at 5 am:

Thursday, October 22

• Heavy to intense rain (100-200 millimeters): Batanes
• Moderate to heavy rain (50-100 mm): Cagayan, Apayao

Friday, October 23

• Heavy to intense rain (100-200 mm): Batanes
• Moderate to heavy rain (50-100 mm): Cagayan

Aside from the provinces mentioned above, Ilocos Norte and Isabela are also likely to have rain with gusty winds from Rosal on Thursday.

The rest of Cagayan Valley, the rest of the Cordillera Administrative Region, Bicol, Ilocos Sur, La Union, Aurora, Northern Samar, and Eastern Samar may have scattered rain and thunderstorms as well, still due to the super typhoon.

PAGASA added that Rosal’s trough or extension might cause scattered rain and thunderstorms in the Zamboanga Peninsula, Western Visayas, Negros Island Region, Lanao del Norte, Misamis Occidental, and Palawan.

Winds from the super typhoon are already reaching portions of Northern Luzon, too. Tropical cyclone wind signals are in effect in the following areas as of 5 am on Thursday:

Rosal might exit the Philippine Area of Responsibility by Friday evening or early Saturday morning, October 24. It entered PAR on Tuesday, October 20.

After leaving PAR, Rosal is likely to be downgraded to a severe tropical storm on Saturday.

Rosal is the Philippines’ 18th tropical cyclone for 2026, and the first for October. PAGASA earlier estimated the country may have one or two tropical cyclones during the month.

The Philippines is currently in a transition period to the northeast monsoon or amihan, following the end of the southwest monsoon or habagat, which was announced last October 5.

The northeast monsoon typically brings surges of cold temperatures, but the upcoming amihan period could be warmer as the existing strong El Niño in the tropical Pacific Ocean is predicted to become very strong in the fourth quarter of 2026. – Rappler.com
