Super Typhoon Rosal Triggers Wind Signal No. 1 Ahead of PAR Entry

Super Typhoon Champi has been given the Philippine name Rosal as PAGASA raised Tropical Cyclone Wind Signal No. 1 over several areas in Northern and Southern Luzon on Tuesday, October 20, 2026.

In Tropical Cyclone Bulletin No. 1 issued at 11:00 AM, PAGASA reported that Rosal remains outside the Philippine Area of Responsibility (PAR), but its approaching circulation is already prompting wind warnings in parts of the country.

PAGASA also forecasts strong to gale-force gusts over the Cordillera Administrative Region, including Baguio City and Benguet, beginning Wednesday, October 21.
