In Trion...portions of the parking lot at Mount Vernon Mills including the personnel office...yards and homes on First and Second Streets near the levee...and athletic fields and other structures off Dalton and Cooper Streets are flooded with up to 3 feet of water. Also near Lyerly...large portions of Lyerly Dam Road near the river are flooded with up to 3 feet of water.
19 Significant flooding expands further into woodlands and fields along the river upstream and downstream from the gage on Rome Boulevard. In Trion...portions of the parking lot at Mount Vernon Mills...yards of homes on First and Second Streets near the levee...and athletic fields off Dalton Street are flooded with two feet of water. The water reaches the personnel office foundation at Mount Vernon Mills. Also near Lyerly...portions of Lyerly Dam Road near the river are flooded with two feet of water.
18 Significant flooding expands further into the woodlands and fields along the river upstream and downstream from the gage on U.S. Highway 27 or Rome Boulevard. In Trion...portions of the parking lot by the river at Mount Vernon Mills...Second Street near the levee...and athletic fields off Dalton Street are flooded with a foot of water. Also near Lyerly...portions of Lyerly Dam Road near the river are flooded with around one foot of water.
17 Moderate flooding begins. The flooding expands further into the woodlands and fields along the river upstream and downstream from the gage on U.S. Highway 27 or Rome Boulevard.
