Summary

Super Typhoon Rosal, also known as Champi, entered the Philippine Area of Responsibility on October 20, 2026, with maximum sustained winds of 185 kph and gusts up to 230 kph, later intensifying to 215 kph winds and 265 kph gusts before weakening as it tracked northwestward. Tropical Cyclone Wind Signal No. 2 remained in effect over Batanes throughout the storm's passage, with Signal No. 1 raised over multiple areas of northern Luzon including Cagayan, Ilocos Norte, Apayao, and the Babuyan Islands. The typhoon caused power failures, building damage, landslides affecting homes and farms, and transit disruptions, including the temporary closure of Basco Airport which resulted in the cancellation of two flights affecting 148 passengers. Rosal exited the Philippine Area of Responsibility by October 24, 2026, with the Intertropical Convergence Zone subsequently bringing scattered rains to other parts of the country.
