22 Major flooding with widespread innundation expands further into the woodlands and fields near the river upstream and downstream from the gage on Alcovy Trestle Road. The water level reaches the top of the bridge with erosion likely to the road on either side of the bridge. Portions of Hamby Lane and Alcovy Trestle Road will be under two feet of water. The bridge and roads will be closed by local officials.
