Significant Flooding Not Expected Saturday

Friday, October 4, 2019 - 4:46pm

City engineers expect Lake Monona to remain near the 100-year flood stage through Sunday, and dry weather early next week will be helpful and welcome. However, some rain is expected on Saturday.

The National Weather Service expects about less than a half of an inch of rain to arrive on Saturday, Oct. 5. The heaviest rain is expected late afternoon to early evening with lighter rain before and after. The storms will be progressive. Moderate rain is possible at times. If the forecast holds, this rain is not expected to cause significant flooding, but residents and visitors should monitor the weather for changing conditions. If conditions change, the City is prepared to respond. Even a prolonged moderate rain could cause some minor flooding given how high the lake levels are.

It takes a team

During the past week, City agencies have put in a lot of hours to keep the community safe and informed. City managers monitored the changing weather, the Madison Police Department blocked flooded intersections and crews from the Traffic Engineering Division put up barricades for road closures. The Streets Division supplied other departments with needed materials. The Engineering Division and Parks Division protected property and kept flooded paths open.  Information Technology coordinated digital outreach to keep the public informed. While we anticipate the next rain moving in on Saturday, the coordination between agencies has been vital and smooth, and will continue to be until drier weather arrives next week.
