MADISON, Wis. (AP) -- Fires at two Madison Gas and Electric substations have knocked about power to more than 11,000 customers on what is promising to be a sweltering day of heat and humidity.
An explosion and fire at the utility's main power center sent a plume of thick, black smoke over Madison's east side about 7:40 a.m. Friday. A second fire near the University of Wisconsin-Madison campus caused police to evacuate Ogg Hall, Smith Hall and the UW Safety Building. Shelter was being made available at the Kohl Center on campus.
Some streets have been blocked off, including East Washington Avenue. There are no immediate reports of injuries.
The National Weather Service issued an excessive heat warning for the area Friday when temperatures in the 90s and high humidity.
