ComEd power – A fast-moving storm toppled tree limbs and damaged power lines across Chicago’s suburbs, leaving 61,000 ComEd customers without electricity before restoration efforts ramped up.
More than 61,000 ComEd customers lost power Monday evening as storms with damaging winds moved through the Chicago area.
The outages were concentrated in the suburbs, with Elgin and Rockford hit hardest, according to ComEd.. By Tuesday morning. power had been restored to about 98% of customers. though several hundred still remained without service into the afternoon.. At 3:30 p.m., ComEd reported 283 customers were still without power, with the largest concentrations around Wheaton and Carpentersville.. The utility said full restoration was expected by 6 p.m.
Officials tied the widespread outages to the storm’s wind-driven damage.. Gusts reaching about 70 mph knocked down tree limbs onto power lines, a pattern that can quickly overwhelm local distribution systems.. For customers. that usually means more than inconvenient darkness—safety risks rise when traffic signals and home power-dependent services go offline. and cleanup efforts often extend for days.
How 70 mph winds knocked out power across Chicago’s suburbs
ComEd spokesperson Tom Dominguez said storms packing high winds were the main cause of the outages. pointing directly to fallen branches striking power infrastructure.. Those impacts are often what turn a weather event into a prolonged restoration timeline. especially when crews have to address downed lines. blocked access roads. and damaged equipment before power can safely be restored.
In many neighborhoods. the immediate aftereffects of the storm were visible in everyday ways—downed limbs. obstructed driveways. and debris that made roads difficult to navigate.. On Monday afternoon. branches sat on top of cars and blocked a street in the Albany Park area. a snapshot of the kind of physical damage that can compound electric outages.
Why the storm’s “wake low” mattered
Weather experts described the winds as linked to a wake low. a pressure disturbance that can form along the edge of a decaying band of thunderstorms or rain.. In simple terms. warm air sinking and dropping pressure near the system helps create a strong contrast with surrounding colder air.. That pressure difference can then generate damaging winds.
A National Weather Service meteorologist, Ricky Castro, said the winds led to both tree damage and some minor structural damage. The storm’s rainfall totals were also uneven. At O’Hare, nearly nine-tenths of an inch of rain fell on Monday, while more than an inch was recorded at Midway.
While those totals weren’t the worst the storms could have produced. they still mattered because the timing came during periods when flooding concerns have already been present in some areas.. Castro said central Illinois ended up taking the hardest hit from the rain.. For Chicago specifically. the region “missed out on the worst of the rain. ” which helped prevent worsening flooding from ongoing conditions and potential renewed river rises.
What residents should expect next as service returns
Tuesday brought milder temperatures, reaching into the mid-60s before lighter showers moved back through the area Tuesday night into early Wednesday. Forecast highs were expected to remain in the 50s through the rest of the week, with conditions gradually settling after the initial storm passage.
Even after power is restored, the broader impact often lingers.. Storm debris can remain a public-safety concern—downed limbs and weakened trees may require evaluation before they’re cleared. and residents may find that landscaping damage or minor roof impacts take time to assess.. For households that rely on refrigeration, medical devices, or internet service, the restoration window can still affect daily routines.
There’s also a practical lesson in how quickly wind can convert a short-lived storm into a multi-hour or longer outage.. The same dynamics that make these systems fast and intense can challenge restoration efforts. since crews must prioritize safety and verify line integrity before power is switched back on.. Areas with the longest wait—such as the zones around Wheaton and Carpentersville—often reflect where damage was concentrated or where access to affected infrastructure was most complicated.
Looking ahead, the key question for residents is how many outages remain beyond the expected restoration deadline.. If additional gusts or follow-on showers intensify conditions, cleanup work and utility response can both slow.. But based on ComEd’s update that restoration was nearly complete by Tuesday morning and targeted remaining outages by early evening. the priority now appears to be finishing the final repairs and preventing secondary complications.
For Chicago-area residents, the storm’s immediate aftermath is a reminder that even a few minutes of extreme wind can disrupt daily life on a large scale—turning downed branches into power outages that crews then work through step by step.
