CHICAGO, Ill. (WCIA) – The National Weather Service in Chicago says they believe yesterday’s rare and powerful dust storm across Central and Northern Illinois could be classified as a “Haboob” based on how things played out.
A Haboob is an intense dust storm caused by strong winds lofting a wall of dust as high as 5,000 feet, leading to a significant reduction in visibility and an increase in wind speed following the passage of the leading edge of the haboob. They also usually lead to blowing dust that lasts for tens of minutes or even several hours.
Typically, Haboobs occur in desert and semi-arid areas, but an extremely unique combination of ingredients with very dry air aloft caused intense downbursts to crash to the ground well ahead of storms combined with low relative humidity, low soil moisture and farming activity that regularly occurs at this time of year.
This dust storm/haboob was a wall of dust running east-west that stretched from along I-55 and I-39 near Bloomington all the way into Western Indiana, lifting north quickly and making it all the way into Lake Michigan.
Top wind gusts included 78 mph on Lake Michigan by Chicago, 75mph in Oxford, IN, 69 mph at Willard Airport, 64 mph in South Chicago, 61 mph in Decatur, 60 mph at Midway Airport and 55 mph in Joliet.
It was the first time the National Weather Service Office in Chicago had issued a dust storm warning for the city. They issued a total of four dust storm warnings. The last time they issued a dust storm warning for their county warning area was on May 7th, 2023 for parts of Ford, Livingston and Iroquois Counties.
The National Weather Service in Lincoln has issued dust storm warnings before. There’s been a number of dust storm warnings used since a massive fiery pile-up killed 8 people on I-55 south of Springfield in 2023.
The dust storm caused many crashes and a few pile-ups, including some on I-55, I-74, US-136, IL-10 and IL-165 in Central Illinois according to state police and local fire departments.
State Police closed part of I-74 west of Farmer City for a period of time to respond to the crashes Friday evening. It has since reopened.
One crash west of Fisher sent 4 people to the hospital. Officials in Ford County also responded to a 7 vehicle pile-up on IL 165 west of Sibley involving a tow truck, 5 cars and an RV. No one was hurt there.
The last time Chicago was impacted by such a significant dust storm was during the Dust Bowl on May 10th, 1934.
