Advice from the General Secretariat of Citizens Protection

* Ensure that drains work properly and aren’t clogged.

* Avoid crossing over flooded areas or streams either as pedestrians or with cars even after the rain stops.

* Avoid working outdoors or taking part in sea sports at coastal areas while there are extreme weather conditions.
