WEST ALTON, Mo. (KMOV.com) -- Officials in St. Charles County continue to warn West Alton residents they may need to evacuate at a moment’s notice due to flooding.
Two levees have been breached in the St. Charles County town since Monday, bringing water up to homes and businesses along Highway 67.
Most businesses have water up to the door and even some windows.
Police said about 15 percent of people who live in West Alton have left the flooded area.
Only one lane of Highway 67 is open Wednesday morning in each direction.
The flooding water began to affect residents when warning sirens were activated at 8:30 p.m. Monday to advise residents that they should evacuate. The evacuation was ordered after a temporary flood barricade put up by MoDOT in the area near Highway 67 and Lincoln Shields Access Road was breached, according to St. Charles County officials.
Authorities said the water levels were higher than the temporary barricade made of sandbags was designed to handle, causing them to break shortly after 8 p.m.
On Tuesday, a levee broke in West Alton on along Wise Rd. just east of Highway 67 on the Missouri River side.
It appeared that mainly farm land was being affected by the breach, which is about 100 feet long.
