The rain is expected to continue through the weekend, and the National Weather Service has declared a Flood Watch from 1:00 AM - 1:00 PM. on Saturday for portions of south-central Wisconsin.
Madison is expected to receive up to 3 inches of rain starting tonight, and some areas could receive more. The heaviest rain is expected tonight and into tomorrow morning. City staff are monitoring lake levels, but they are not a concern since they are low.
City Engineering crews have been clearing debris from storm grates. Crews clear debris from priority drainage areas ahead of the storms to make sure the system functions as well as it can.
