Severe Storms and Heatwaves in Germany: How to Stay Safe

Introduction

Germany is experiencing a volatile week of extreme weather. Following hailstones the size of tennis balls that caused significant property and infrastructure damage in parts of northern Germany, meteorologists are warning that severe thunderstorms, heavy rain, and intense heat could affect other regions of the country in the coming days. For expats living in Germany, especially those who are new to the country, understanding how to access weather warnings and what to do during extreme events is essential. Germany has reliable public warning systems, but knowing how to use them — and what they mean — makes a real difference.

Understanding Germany's Weather Warning System

The Deutscher Wetterdienst (DWD) is Germany's national meteorological service and the primary authority for weather warnings. It uses a four-level colour-coded alert system:

• Level 1 (yellow): Preliminary information, low-impact weather possible
• Level 2 (yellow/amber): Significant weather event expected, some disruption likely
• Level 3 (orange): Severe weather event, potential danger, take precautions
• Level 4 (red/violet): Extreme weather event, serious danger, follow official instructions immediately

You can access DWD warnings through the WarnWetter app (free, available in English interface), the DWD website (www.dwd.de), or the NINA app, Germany's official civil protection warning app, which also covers other emergencies like floods and industrial accidents.

Many German municipalities also broadcast warnings via loudspeaker vehicles, SMS alert systems, or local radio. If you hear sirens, tune immediately to a local radio station or check NINA for instructions.

What to Do During a Severe Storm in Germany

During the kind of thunderstorm system currently affecting parts of Germany, standard safety advice includes:

Indoors:

• Stay inside and away from windows during heavy lightning and hail
• Unplug sensitive electronics to protect against power surges
• Do not use landline telephones during lightning storms
• If your building has a basement and flooding is possible, move valuables upstairs

Outdoors:

• Avoid open fields, hilltops, and isolated trees — all attract lightning
• If caught outside, crouch low with feet together; do not lie flat
• Move away from water bodies immediately
• If driving, pull over safely and avoid flooded roads — even 30 cm of fast-moving water can carry a car

Hail:

• Move vehicles under cover if possible when a hail warning is issued
• Stay indoors — large hailstones cause serious injury
• Do not attempt to rescue garden furniture or outdoor items during a hail storm

Heat and Storms: A Dangerous Combination

The current weather pattern — intense heat building up followed by sudden violent storms — is a classic Central European summer scenario that is becoming more frequent and severe. Heat stress weakens the body and reduces reaction time, which can compound the risk during rapid weather changes.

If you are spending time outdoors in the heat and receive a storm warning on your phone, take it seriously and find shelter promptly. The window between a calm sunny afternoon and a severe thunderstorm can be very short — sometimes under 30 minutes.

Frequently Asked Questions

How do I get weather warnings in English in Germany?

The DWD WarnWetter app can be set to English. The NINA app is primarily in German, but its alert icons and maps are easy to interpret regardless of language. Google Weather and Weather Channel apps also pull DWD data and display it in your phone's language. Setting your phone's emergency alert system to receive German cell broadcast alerts (Katastrophenschutzmeldungen) is also recommended.

What should I do if my home is damaged by hail or flooding?

Document all damage immediately with photos and video before moving or removing anything. Contact your Hausratversicherung (contents insurance) and, if applicable, your Gebäudeversicherung (building insurance) as quickly as possible — most policies require prompt notification. If you are a tenant and the building itself is damaged, notify your landlord immediately in writing (email is acceptable). For emergency situations where your home is uninhabitable, contact your local municipality (Gemeinde or Stadtverwaltung) for emergency accommodation options.

Conclusion and Next Steps

Extreme weather is an increasing reality in Germany, and this week is a reminder of how quickly conditions can change. Download the WarnWetter or NINA app now if you have not already, and make sure notifications are enabled. Share warning information with family members or flatmates who may not be aware of the alerts. Being informed in advance is the single most effective safety measure available to you.
