How to read DMI's warnings
DMI has three warning levels and a risk notice. Each level has its own colour, and category 3 is the most serious. An early warning (forvarsel) can come up to five days ahead, while the warning itself is issued at most 36 hours ahead.
| Level | Colour | What to do |
|---|---|---|
| Risk of severe weather (risk notice) | Blue | Not a warning yet. Keep an eye on the forecast. |
| Category 1 – Severe weather (voldsomt vejr) | Yellow | Be aware: the weather may affect you. Take care outdoors. |
| Category 2 – Dangerous weather (farligt vejr) | Orange | Be prepared: follow the authorities' advice and take extra care outdoors. The weather may disrupt traffic and supplies. |
| Category 3 – Very dangerous weather (meget farligt vejr) | Red | Follow the authorities' advice: there is a high risk that the weather will affect you. It may disrupt the normal functioning of society. |
On this page the warnings come from MeteoAlarm, the shared European warning service, which uses yellow, orange and red. DMI's category 1 is shown as the yellow level. Risk notices and early warnings are on dmi.dk/varsler and in DMI's app. We haven't linked the warnings to municipalities yet; each warning's title names the area.
When does DMI issue a warning?
DMI warns according to fixed criteria agreed with the Danish Emergency Management Agency and the national police. A selection:
| Weather | Category 1 | Category 2 | Category 3 |
|---|---|---|---|
| Cloudburst (in 30 minutes) | 15–25 mm | 25–35 mm | over 35 mm |
| Heavy rain (in 6 hours) | 25–35 mm | 35–50 mm | over 50 mm |
| Wind (mean wind) | strong gale, over 20.8 m/s | storm, over 24.5 m/s | hurricane force, over 32.6 m/s |
| High water, inner Danish waters | 125–140 cm | 140–160 cm | over 160 cm |
| High water, west coast | 190–250 cm | 250–300 cm | over 300 cm |
| Heavy snow (in 6 hours) | – | 15–20 cm | over 20 cm |
DMI also warns of freezing rain, snowstorms, drifting snow, dense fog (visibility under 100 metres), severe thunderstorms, heatwaves and cold spells. Since 1 September 2025 DMI has also warned of flooding from rivers and lakes; categories 1, 2 and 3 correspond to events that statistically occur once every 5, 20 and 50 years. Wind warnings can cover an area as small as a single municipality, and a cloudburst is local: most people in a warned area won't get one.
