Some Chicago-area counties will be under a Red Flag Warning Monday as dangerous fire conditions threaten numerous suburbs.
The warning takes effect at noon in Winnebago, Boone, McHenry, Lake, Ogle, Lee, DeKalb, Kane, LaSalle and Kendall counties. It remains in effect until 8 p.m.
According to the National Weather Service, “the combination of strong winds, very low relative humidity, exceptionally dry fuels and warm temperatures will promote extremely dangerous behavior of any fires.”
With winds gusting up to 30 mph and relative humidity as low as 15 to 25 percent, “critical fire weather conditions” will likely be seen, officials said.
NWS said outdoor burning is “strongly discouraged.”
