The National Steering Committee for Disaster Prevention and Control recommends localities in the affected areas in the Northern and Central regions to proactively ban sea activities based on the actual situation, call for and arrange for ships to seek safe shelter; evacuate people while ensuring COVID-19 safety.
Localities should check and review areas at high risk of flash floods and landslides in low-lying coastal areas; check and review, proactively implement plans to ensure the safety of dikes and reservoirs, especially in vulnerable key areas, reservoirs that are already full, and construction sites that are under progress.
Localities should be ready with working groups to direct on-site, maintain rescue forces, and respond promptly when required; organize 24/7 duty shifts…
