CHICAGO - The National Weather Service has confirmed two tornadoes touched down in the Chicago suburbs during Monday's severe weather outbreak.

What we know:

One tornado tracked through Lansing before lifting just east of the Illinois-Indiana state line in Munster, Indiana. The storm was rated EF-1 on the Enhanced Fujita Scale, with estimated peak winds of 110 mph, according to the NWS. 

Meteorologists also confirmed an EF-0 tornado struck Glen Ellyn in DuPage County, producing peak winds of about 80 mph.

In addition to the tornadoes, survey teams found evidence of damaging straight-line winds exceeding 70 mph in both Carol Stream and Downers Grove, where strong thunderstorms caused wind damage but no tornadoes.

The National Weather Service also reviewed video showing what appeared to be a possible tornado near Watseka in Iroquois County. However, investigators said they were unable to confirm that the funnel cloud actually touched the ground, so it will remain classified as a funnel cloud rather than a tornado.

Storm survey crews are still assessing damage in Glenwood, Hazel Crest, Homewood, Markham and Orland Park.

Meteorologists said the damage path near Hazel Crest has been especially challenging to analyze because the storm's rotation appeared to loop back on itself, making it more difficult to determine exactly what happened.

What's next:

The National Weather Service said it expects to release additional survey findings once crews finish evaluating the remaining damage.
