Heavy rain following dry weather flooded streets in the east coast town of Kalmar, with 1,700 lightning strikes recorded in the area.
Up to 40 millimeters of rain fell in Kalmar on Tuesday, leaving about 24,000 households without electricity for three hours.
On Wednesday, the streak of rain was supposed to move north through central Sweden, but by morning all heavy rain warnings previously issued by the national meteorological agency, SMHI, had been canceled and the heavy rain seemed to be subsiding.
However, SMHI meteorologist Matthias Lind warned of sudden localized downpours. "If they hit populated areas, it could have serious consequences if the water cannot be absorbed when such a large amount falls in a short time, so it all depends on where these showers end."
Stockholm is expected to receive about four millimeters of precipitation on Wednesday, but sunny weather is forecast in northern Sweden, where wildfire warnings are still in effect.
