According to the National Center for Hydro-Meteorological Forecasting, in the past 12 hours (from 7:00 p.m. on May 28 to 7:00 a.m. on May 29), heavy rain has appeared in many northern provinces, including places with rainfall exceeding 200mm.
Some major rain points include: Tam Thanh (Phu Tho) 209.8mm, Tan Minh (Lang Son) 170.4mm, Tan Pheo (Hoa Binh) 138.6mm, Yen Binh (Yen Bai) 123mm...
Soil moisture models show that in many areas of these provinces, the humidity is close to or reaches a saturated state (over 85%), increasing the risk of landslides when the rain continues.
In the next 3-6 hours, the rain will continue to be widespread. It is forecasted that the provinces of Lao Cai, Ha Giang, Tuyen Quang, Yen Bai, Phu Tho, Cao Bang, Bac Kan and Thai Nguyen will have common rainfall from 20-40mm, some places over 90mm.
