Tornado watches through Saturday evening as severe weather batters Chicago area again

CHICAGO - Tornado warnings were issued for a dozen cities and towns in the Chicago area, including Manteno, Peotone, Bourbonnais, and Bradley on Saturday.

Tornado sirens briefly blared in parts of Chicago Saturday afternoon, but a tornado warning was allowed to expire after rotation clouds passed over the North and Lower West sides of the city.

Forecasters say residents still need to "remain vigilant" through the evening with a tornado watch in effect until 7 p.m., as "the ingredients are there for potential severe storms, including rotating ones with a tornado threat."

Additional storm cells have been tracked across the area, bringing with them severe thunderstorms, the weather service said.

The weather service also issued a flash flood watch that will remain in effect until 6:15 p.m. Showers and thunderstorms are expected for the next 24 hours, the weather service said, especially along and southeast of Interstate 55.

The severe weather comes days after a tornado ripped through a few suburbs west of the city.
