The announcement is valid until Sunday and applies above all to the southern part of the county, where the maximum daytime temperature is expected to exceed 26 degrees.
With a maximum daily temperature of at least 26 degrees three days in a row, it means an increased strain on the body, which can cause problems, especially for risk groups, writes SMHI.
If the forecast changes to a maximum daily temperature that reaches at least 30 degrees for at least three consecutive days, the message is updated to a warning.
