Because thunderstorms often develop very suddenly and quickly, and their path is not easy to predict, there is potentially very little time to prepare. In stormy weather, you should therefore be prepared for sudden, heavy precipitation (rain or hail), as well as wind gusts and lightning.
Information on the potential effects and danger levels of storms can be found here.
What to do in the event of an approaching thunderstorm:
- Keep an eye on local weather developments, and act appropriately, according to the information you receive on the conditions;
- Heed the push notifications on the MeteoSwiss App;
- Don’t go hiking in the mountains or walking in forests;
- Stay away from water;
- Don’t leave potted plants, sun umbrellas, awnings, light-weight plastic chairs etc. unsecured and out in the open (hail and wind damage);
- If possible, park the car in a garage (hail damage);
- Cover sensitive plants with a protector (for hail);
- Unplug electrical appliances (e.g. TV, computer) from the main outlets.
