A lightning strike exploded the chimney of a home and launched debris into neighboring yards in Wauwatosa. It happened near 72nd Street and Hillcrest Drive late Tuesday afternoon. Debris shattered car windows in the driveway, and bricks ended up inside a neighbor's home. Firefighters were able to extinguish the flames before the fire spread, and no one was hurt. Emma Hermsen, who lives next door, thought it was a gunshot, but then she saw smoke. "All of a sudden, the entire house started shaking, and it was like the lightning was almost in the house," Hermsen said. "There was purple light everywhere." The Wauwatosa Fire Department said this was the third lightning-related fire so far this year.
