SMHI Issues Orange and Yellow Warnings for Heavy Rain and Flooding in Central Sweden

On July 18, 2026, the Swedish Meteorological and Hydrological Institute (SMHI) issued severe weather warnings for central and eastern Sweden, particularly highlighting the risks of heavy rainfall and flooding. An orange warning for heavy rain is active in parts of Östergötland, including areas from Norrköping to Linköping and Kisa, where rainfall between 60 to 80 millimeters is expected between 3 PM and 9 PM. This intense rain raises the risk of flooding and potential property damage. In addition, a yellow warning covers broader parts of central Sweden, including Sörmlands län and northern and western Götaland, where 30 to 60 millimeters of rain may fall with ongoing thunderstorms throughout the day.

SMHI meteorologist Sandra Fyrstedt noted that heavy showers had already started by early afternoon in Sörmlands län. Residents are advised to clear gutters and drainage systems to prevent damage and secure belongings prone to water damage. Motorists should expect poor visibility and adjust their driving speed accordingly to allow for longer travel times due to flooded roads and water accumulation.

The severe weather has already led to significant impacts along Sweden’s west coast, including flooding, power outages affecting 21,000 customers on Orust and Tjörn, and lightning-caused barn fires in Trollhättan and Vänersborg. Rescue services report numerous calls due to water damage in residential and commercial properties.

SMHI recommends caution and staying informed as the weather conditions evolve, with heavy rain potentially continuing into Sunday. The warnings extend from Östergötland through much of Götaland and up to Södertälje in Stockholm County but do not include Stockholm city itself.
