On Monday, Länsförsäkringar in Skåne had received around a hundred claims reports. Most of them concern damage to buildings due to high flows from outside. But so far, there have been few reports of the homeowner's nightmare – that stormwater systems become too full and wastewater begins to flow into the basement.

If you live in an area that is sensitive to flooding, you should now do what you can to minimize the damage, says Joel Lith at Länsförsäkringar in Skåne.

"Then you can prepare by trying to cover floor drains and remove expensive and emotional things from the floor in the basement. They cannot be saved if wastewater were to come in," says Joel Lith.

Worst in Jönköping and Örebro

On Monday, the insurance company Folksam had received about 150 claims linked to the storm Han's rampage. Most reports have come in from Jönköping and Örebro and concern both the rain that has fallen and damage caused by strong winds and fallen trees.

In western Sweden, the amount of rain was lower and the problems fewer than forecast predicted, but it is too early to breathe a sigh of relief.

"So far, we have managed but we are preparing for the coming days. Then there will be large amounts of water in combination with wind. It's the combination that makes it difficult," says Caroline Josefsson at Länsförsäkringar in Västra Götaland and Bohuslän.

Heightened readiness

The insurance company If had not received more claims than usual on Monday morning, but has increased its preparedness for Tuesday and Wednesday. Trygg-Hansa has not received any large numbers of notifications at the moment either, but the company is monitoring developments.

"This low pressure moves over large geographies, so it will take a while before we see the full effect of it," says Håkan Franzén at Trygg-Hansa.
