Storm summary for January 28-30, 2012

January 31, 2013
tags:

Total Precipitation: 2.74″
Greatest One-Day Total: 1/29 7:00a – 1/30 7:00a, 1.84″

Impacts

  • The northern flood pool in Armstrong Park is full, and spreading into the northern baseball field.
  • The Veterans Park pedestrian bridge is under about 3′ of water.
  • Illini Drive had about 2-3″ of water depth near the curbs at Armstrong Park.

Discussion

According to the National Weather Service, our ground was mostly frozen (at depths > 8″ deep) during the event. As a result most of the rain that fell converted directly to runoff. A similar storm in June would cause minimal impacts.

Very fortunately, there was no snow cover on the ground for this storm. In December 2008, over 2″ of water was locked in the snowpack, and another 2″ of rain fell, causing much greater impacts.

No significant precipitation is expected for the rest of the week, into next week.
