Stockholm - The Swedish weather service SMHI on Monday warned of more local thunder storms and lightning in parts of central Sweden, the day after two people were killed by lightning.

Two people who suffered severe burns and have yet to be identified were found Sunday in the province of Dalarna, north-west of Stockholm.

Police believed they had sought shelter during a thunder storm when the temporary shelter was hit by lightning.

Falun, the main city in Dalarna, registered the unusually high temperature of 33 degrees Celsius on Sunday.

In addition to thunder storms, the Swedish Meteorological and Hydrological Institute, SMHI, has warned of forest fires. (dpa)
