Wind gusts to exceed 60 mph
October 25, 2010
A high wind warning for the DeKalb area is in effect from 7 a.m. today until 7 p.m. Wednesday, according to the National Weather Service of Chicago.
Wind gusts are expected to exceed 60 mph during the most severe thunderstorms this morning, said NIU meteorologist Gilbert Sebenste.
This afternoon, wind gust speeds will reach up to 60 mph and will diminish tonight to between 40 and 50 mph, he said. Wednesday night, the system will intensify to 60 mph gusts again.
This upcoming cyclone, or low pressure system, is expected to rank second among a list of other notable cyclones over the Great Lakes as far back as 1913.
Sebenste said low pressure systems are caused by a temperature difference on either side of a storm system. The warm, moist air moving into the DeKalb area will create a “very intense” contrast with cooler air moving in from Canada.
According the National Weather Service, non-secure objects may become airborne and falling trees limbs and occasional power outages can be expected.
If students have any outdoor furniture like patios or grills, they should bring them inside, Sebenste said.
Students should also use caution when driving today and Wednesday, he said.
