The biggest difference between the two systems is that the new one, which was introduced on October 26, takes greater account of the consequences of the weather than before.
In the old system, the criteria for warnings were the same across the country, even if, for example, heavy snowfall causes significantly greater problems in central Stockholm than in more sparsely populated areas, explains Fredrik Linde, head of the forecast and warning service at SMHI.
- The basis is that we want to give both individuals and local actors in society better conditions to prepare for a difficult weather situation.
We want to provide a better decision-making basis, he says.
In order to better understand the geographical differences, SMHI has collaborated with a wide range of actors in the work on the new warnings, says Linde.
- The old system was good, but even what is good can be made even better.
This is not something we have been able to come up with ourselves.
It is actors above all at local and regional level who have knowledge of the consequences.
