SMHI's new system for weather warnings focuses on the consequences that the weather can have, so that society can have better crisis preparedness.

The renewed system will make it easier to understand what problems the weather can cause.

Regional consequences of the weather

SMHI cooperates with the county administrative boards before a decision on a warning is made so that the warnings become more relevant and adapted to regional conditions.

Warning level is set based on the consequences that the weather is expected to have in a certain area.

Risk factors are regionally adapted.

Class 1, 2 and 3 warnings disappear

Today, a snow warning looks the same, no matter where in the country it snows.

But the consequences of a couple of decimetres of snow are not the same in the interior of Norrland as in a city in southern Sweden.

The current class 1, 2 and 3 weather warnings disappear and yellow, orange and red warnings are introduced instead, of which red is the most serious level.

All levels in the new warning system mean that difficult weather can have consequences.
