April 27 (UPI) -- Chicago airports have canceled more than 500 flights as springtime snowfall has pounded the area.
The city's O'Hare International Airport listed 581 fights canceled, as of 3:02 p.m. Saturday, as the National Weather Service reported a "significant storm" moving across the region through the evening.
"A swatch of heavy wet snow is expected generally along the north of the Interstate 88 corridor," the NWS said. "Strong northeast winds may further reduce visibility where heavy snow develops. The heavy wet snow may also cause tree damage and power outages."
Total snow accumulations of 5 to 8 inches are expected with snowfall rates of 1 to 2 inches per hour possible, and wind gusts as high as 35 mph through the afternoon, according to the storm warning.
With overnight low temperatures dropping into the lower 20s, a "hard freeze is possible," the NWS said.
