A warning of "torrential rain" has been issued for large portions of Götaland and southeastern Svealand in Sweden due to warm, humid air moving over the region. Thunderstorms may arise from southern latitudes or develop over the sea, but their exact locations and intensity are challenging to predict, says Ida Dahlström, a meteorologist at SMHI.
The anticipated rainfall quantities are hard to predict, as a true downpour is defined as one millimeter of rain per minute or 50 millimeters in an hour—conditions uncommon in Sweden. SMHI characterizes the storm as "torrential rain-like" due to the significant short-term rainfall it may bring.
SMHI's warnings extend to Öland and the southernmost parts of the country, cautioning against flooding on roads and in basements. The alerts are in place from 08:00 to 15:00 on Tuesday for southern Götaland, and from 11:00 to 23:00 for central Götaland to southeastern Svealand.
