CHICAGO, IL — The National Weather Service has confirmed that the derecho that hit the Chicago area and other parts of Illinois Monday brought with it a total of 14 tornadoes to the state, plus a 15th tornado that hit northwest Indiana. All of them rated an EF1 or EF0 on the tornado rating scale. The Fujita scale, or Fujita–Pearson scale, rates tornado intensity based primarily on the damage tornadoes inflict on structures and vegetation.

Here's where the 14 Illinois tornadoes hit:

Rogers Park/Lincolnwood: In the midst of the storm, the weather service confirmed that a "brief tornado" touched down Monday afternoon in Chicago's Rogers Park neighborhood before moving out over Lake Michigan and becoming a waterspout. This EF1 tornado initially touched down south of the intersection of Crawford and Touhy Avenues in the suburb of Lincolnwood. The most intense damage, consistent with that of a high-end EF1 tornado, occurred about a mile from the lakefront.

Yorkville, South Plainfield: At around 3:15 p.m. Monday, this EF1 tornado "started on the far south side of Yorkville near Walsh Drive where a pergola was destroyed, siding was ripped off a house, and parts of a fence and a tree were thrown over a roadway. Eyewitness accounts indicate the debris was lifted and twirled," trees were mangled, a farm building was destroyed and a grain bin was bent inward. Six power poles were snapped along Ridge Road, and a 1,000 to 1,500-pound auger was moved about 50 feet. Winds hit 105 mph as the tornado continued into Plainfield neighborhoods south of Renwick Road.

Wheaton: A very brief EF1 tornado touched around 3:35 p.m. Monday down near the intersection of Seminary Avenue and Scott Street before moving northeast where it knocked a roughly 50-foot steeple around to the north side of the College Church in Wheaton. The tornado then produced minor tree damage before lifting near College Avenue and Howard Street.

Oak Forest/Midlothian: An EF1 tornado hit Cook County around 3:54 p.m. Monday, touching down east of South Harlem Avenue in Oak Forest, then moving along 151st Street, producing mainly minor tree and structural damage before lifting near the I-57/I-294 interchange in Midlothian. The worst and most concentrated damage happened near Midlothian in the region between Cicero Avenue and Pulaski Road. Several large trees and power poles were snapped near their bases in this region, producing damage consistent with an EF1 tornado.

Park Forest: The brief EF0 tornado touched down very close to the Cook County/Will County line, and "very little structural damage was noted in this area."

Lombard/Villa Park: The same storm that produced the Wheaton tornado also hit nearby Lombard around 3:39 p.m. Monday, causing tornado damage immediately east of I-355. The EF1 tornado uprooted trees, snapping some at the trunk, as well as causing some house damage including a few with substantial roof damage. The worst damage occurred near and around the Lombard Common, just south of St. Charles Road.

Kane County: Kane County officials also said Tuesday that the weather service confirmed that an EF1 tornado touched town in northwest Elburn near Kaneville around 3:12 p.m. Monday. A photo taken by an employee of the Kane County Sheriff's Office of Emergency Management shows the small and "very weak" vortex stretching from the clouds to a farm near Interstate 88.

Grant Park: This EF0 tornado touched down in Kankakee County just after 4 p.m. Monday, producing 80 mph winds and "considerable tree damage."

Marengo: On Wednesday, the weather service confirmed another EF1 tornado near Marengo in McHenry County. The tornado hit just after 3 p.m. Monday. Tree damage consistent with winds around 95 mph occurred immediately northeast of I-90. The tornado heavily damaged a single family home near Maple Street before heading northeast and lifting near Coral and Dunham Roads.

Southwest Rockford: This EF0 tornado hit around 2:57 p.m. Monday, touching down near the intersection of Pierpont Avenue and Montague Road and continuing northeast into the southwest side of Rockford. All damage was to trees along the tornado path.

Winnebago/Boone County: At 2:47 p.m., an EF1 tornado "associated with the same supercell thunderstorm that produced an initial brief EF0 tornado immediately southwest of Rockford" hit Winnebago and Boone Counties.

DeKalb County: Just before 4 p.m. Monday, another EF0 tornado hit Kirkland, Illinois. "This brief tornado crossed Buck Road and Pearl Street before lifting in a field east of Myelle Road," the weather service said.

Ottawa: This EF1 hit LaSalle County at 2:59 p.m. Monday, impacting "several businesses (and) ripping off well-anchored roofing material and snapping a power pole at its base." Winds hit 100 mph as the tornado continued east, ripping shingles off roofs of buildings and houses just west of Route 23 and shredding trees.

Spring Grove: This EF1 tornado hit around 3:41 p.m. Monday, moving from northwest Lake County, Illinois, to Camp Lake, Wisconsin.

According to the weather service, the Rogers Park tornado touched down in the neighborhood around 4 p.m.

"It was crazy, madness, really dark," Rogers Park resident Jasman O'Connell told NBC Chicago. "I was really scared."

Another neighbor said he came outside to find his car "in half" due to storm damage.

The strong storms left more than 500,000 households without power in the Chicago area Monday, and ComEd warned customers it could take until Saturday afternoon to restore power to all areas.

The weather service said there were more than 100 severe storm reports Monday in northern Illinois and northwest Indiana, including some reports of significant damage.

Five people were hurt, and a disaster was declared in Forreston, Illinois, where winds of up to 100 mph roared through the village. Village President Mark Metzger told the Rockford Register Star there were widespread reports of damaged trees and downed wires, as well as structural damage. A mobile home park near Illinois 72 was hardest hit.

Despite the intense winds, there were no reported storm-related deaths, the weather service said.
