Every figure here is a weather model’s estimate for an area, not a rain gauge and not a road camera. A model cannot see a landslide, a rockfall, roadworks or a closure.
Rain and landslides do not line up neatly here. In August 2024 the Halsema's roadbed gave way at Pilando, Buguias, after days of rain; in November 2025, Super Typhoon Uwan cut the Baguio–Bontoc road and the Dantay–Sagada road at the same time. A clear morning in Sagada says nothing about a slide two hours down the road — and no weather model can see one coming.
This page describes the weather along the corridor. It cannot say whether the road is open, and it is never a judgement that driving is safe.
