Wind may knock down loose tree limbs or blow over lawn furniture -- but that will likely be the worst of the effects felt in the Louisville area from a major storm pummeling the northeast United States, according to the National Weather Service in Louisville.A wind advisory is in effect until 8 p.m. Tuesday, the National Weather Service said.Until then, Louisville and nearby areas will endure sustained winds between 20 and 30 miles per hour, with gusts as strong as 45 miles per hour, said Ryan Sharp, a meteorologist for the National Weather Service in Louisville.Drivers of high-profile vehicles -- such as tractor-trailers -- may struggle in those sorts of crosswinds, Sharp said.The worst of the wind will be during the day on Tuesday, Sharp said. The Louisville area may get rain from Sandy, but the greatest possibility is in the eastern portion of Kentucky, where snow may even be possible, Sharp said.Meanwhile, Louisville International Airport flights to and from cities including New York City, Newark, N.J., Philadelphia and the Washington, D.C., area have been canceled, said Trish Burke, spokeswoman for the Louisville Regional Airport Authority.
