More than a month's worth of rain fell on Chicago in 90 minutes on Tuesday evening, according to the National Weather Service (NWS).

"There were numerous reports of flooded viaducts, several reports of water rescues, and a few reports of flooded basements," the NWS said.

A flash flood warning was issued until 12.45 a.m. on Wednesday for Chicago and Cicero.


Why It Matters

The extreme rainfall in Chicago follows deadly floods in Texas' Hill Country last week that have led to the deaths of more than 100 people.

In New Mexico, flash floods also killed at least three people on Tuesday, including two children in the resort village of Ruidoso, according to Reuters.

What To Know

According to the NWS forecast office in Chicago, more than five inches of rain fell within the space of 90 minutes west of the United Center on Tuesday evening.

This exceeds the largest average amount of monthly precipitation that the city receives — around 4.5 inches — according to data from the Illinois State Climatologist.

Chicago's West Side, including Homan Square, Douglass Park, and Tri-Taylor, faced especially challenging conditions, according to CBS Chicago.

It added that a total of 6.6 inches of rain fell on Douglass Park, while emergency crews conducted rescues at Western and Ogden avenues and Ashland Avenue and Kinzie Street.
