A microburst occurred in Cornwall, downing several large hardwood trees, some falling on power lines, a house and a shed. The microburst was confined to an area bounded by Jacquelin Street, Briarcliff Place, Mill Street and Bede Terrace. One tree was sheared off just above the ground. Wind speeds were estimated to be between 86-96 mph with the microburst, with a maximum path width of 1/4 mile and a path length of one mile.
Waters from the Moodna Creek washed away the bridge at Forge Hill Rd. in New Windsor, which resulted in the indefinite closure of the road. A vehicle parked on Old Forge Hill Rd. also near Moodna Creek slid into the creek after rising water eroded the surrounding area.
