BATAVIA,Ill. — National Weather Service personnel routinely conduct storm surveys after tornadoes and wind storm events that move through areas of the nation. Information gathered from conducting storm surveys not only provides one with valuable information approximately the storm structure, but also approximately the failure and quality of construction of structures. This information can lead to ways of mitigating the effects of damaging winds either by strengthening the existing structure or by constructing a secure room.
