Guam experienced substantial impacts as Champi's northern eyewall grazed the island, causing tree damage and some roofs to be torn off buildings. The storm's peak winds of 185 mph (296 km/h) pose a significant threat to any landmass in its path. However, Champi is expected to continue moving northwest and gradually weaken, reducing the immediate risk to populated areas. The storm's earlier proximity to Guam highlights the potential for severe wind damage and disruption in affected regions.
