The National Civil Defense Committee calls on local authorities to prepare for heavy rain and thunderstorms expected from the evening of 8 June to the night of 9 June 2026.
Key forecast
Moderate to very heavy rainfall (30–80 mm on average, locally >200 mm) with a risk of intense downpours (>100 mm/3h).
Required actions for local authorities
- Monitor weather bulletins continuously and quickly relay alerts to the population.
- Preemptively evacuate residents from high-risk areas (slopes, hillsides, riverbeds, low-lying areas, urban flood-prone zones).
- Mobilize and deploy response teams to clear blocked waterways and provide immediate assistance in case of incidents.
- Strengthen local communications to inform residents about protective measures and evacuation procedures.
- Maintain operational duty shifts and send regular reports to the national level via the Directorate in charge of dike management and disaster prevention.
