Overview
- Meteorological agencies say Chan-hom is approaching northeastern Honshu on a northwest track and is expected to cross the main island before weakening over the Sea of Japan.
- Forecast peak intensity is near 60 mph sustained winds with gusts over 100 kph and hourly rainfall rates up to about 40 millimeters, raising landslide and flash‑flood risk in Fukushima and northern Kanto/Tohoku.
- All Nippon Airways warned flights at Haneda, Narita, Fukushima and Sendai may be affected and ferry operator MOL Sunflower canceled services between Oarai and Tomakomai for the coming days.
- U.S. bases in Japan have maintained their seasonal tropical cyclone readiness posture as local authorities prepare likely heavy‑rain, strong‑wind and landslide warnings.
- Chan-hom is developing alongside other northwest Pacific systems, increasing forecast uncertainty and heightening disruption risk for residents, holiday travelers and coastal communities.
