Typhoon Bawei Triggers 'Rockfall Rain' in Nantou, Taiwan; Early Road Closure Averts Disaster

Authorities in Nantou, Taiwan, successfully averted disaster by preemptively closing a section of Provincial Highway 14 in Ren'ai Township as Typhoon Bawei approached, bringing strong winds and heavy rain. The road section near Yunlong Bridge experienced a significant "rockfall rain" event on the afternoon of July 11, but the timely closure prevented any injuries or vehicle damage.

Ren'ai Township saw intensified winds and rain after noon due to the typhoon, with accumulated rainfall reaching approximately 100 millimeters. While other mountain roads experienced fallen trees and scattered rocks, the stretch of Provincial Highway 14 near kilometer marker 86.4 at Yunlong Bridge became the site of a dramatic "rockfall rain." Stones continuously tumbled down from the slope onto the road, creating a startling scene.

The Puli Works Office of the Directorate-General of Highways reported that sporadic rockfalls had begun earlier in the morning. Considering the forecast for increased rainfall in the afternoon and the risk of slope instability, the office issued an advance warning and closed sections of Provincial Highway 14 from kilometer 86 to 92, and from 94 to 99, starting at 11 a.m. This proactive measure proved effective in preventing potential harm to people and vehicles. The public is reminded to avoid mountainous areas during typhoons to ensure their safety.
