An ice storm warning that was in effect from 6 p.m. Tuesday to 6 a.m. Wednesday for McHenry and several other counties caused most schools to cancel evening activities Tuesday.
Harvard School District 50 and Community School District 300 announced schools would delay their start times Wednesday because of the weather.
Both districts will begin two hours later than normal. Half-day preschool programs in District 300 and the morning program at Washington Elementary School are canceled. District 50’s before-school programs also are canceled.
The National Weather Service warned of significant ice from freezing rain. Ice accumulations between one-tenth and four-tenths of an inch were estimated, with the highest amounts coming along a line from Streator to Morris to Joliet to downtown Chicago.
Power outages and tree damage is possible because of the ice, according to the agency.
Travel also may be difficult on untreated roads. For those who must travel, the National Weather Service recommends keeping an extra flashlight, food and water in vehicles.
In addition to McHenry County, the ice storm warning was in effect for DeKalb, Lake, Kane, DuPage, Cook, La Salle, Kendall, Grundy and Will counties.
