Per Stenborg is a meteorologist at SVT. He says it is unusual for it to rain so much during this time of year.

- To be in the winter season is 40 millimeters very much, he says.

SMHI warns

And the rain is expected just a week after the Ciara storm. After Sunday's heavy rain, SMHI has issued a Class 1 warning for high flows for the upper parts of Viskan and Ätran from Åsunden and downstream towards Vessigebro.

- Since it is already high flows and saturated in the ground, this rain learns to do more than Sunday, says meteorologist Per Stenborg.

The rescue service is rusting

When Ciara blew through on Sunday, Södra Älvsborg's Rescue Services Association went out on 27 alarms linked to the storm. Now the rescue service is preparing for Dennis and has brought in extra staff this weekend.
