Context & protective measures

Background: dry spells are becoming more frequent and longer in Switzerland. Prolonged drought lowers groundwater and spring levels, strains the drinking-water supply of smaller municipalities and agriculture, and markedly increases the risk of forest and field fires. The FOEN rates the situation by region across several warning levels.

Recommendation

Likelihood of occurrence is low, but the potential impact is high. Prepare using the linked guide on protection against heat and drought.

What to do now

Use drinking water sparingly, observe municipal water-use restrictions and fire bans, avoid open fires outdoors and barbecuing in the forest, and keep a drinking-water reserve. Follow the guidance of your municipality and the authorities.
