In the next 3 - 6 hours (from 7:30 a.m. on June 23), the Northern provinces will continue to have rain with common rainfall from 5 - 15mm, some places over 40mm.
In the next 6 hours (from 7:30 a.m. on June 23), there is a risk of flash floods on small rivers and streams, landslides on steep slopes in many districts.

The meteorological agency warns that the risk of natural disasters due to flash floods, landslides, and land subsidence due to heavy rain or water flow is level 1.
Flash floods and landslides can have a very negative impact on the environment, threatening people's lives; causing local traffic congestion, affecting the movement of vehicles; civil and economic works, causing damage to production activities and socio-economic activities.
The meteorological agency recommends that local authorities pay attention to reviewing bottlenecks and vulnerable locations in the area to take preventive and response measures.
