Fast Facts

  • A quick-moving weather system brought southwest winds on Thursday morning the 5th gusting to 35-44 mph, and these winds then turned westerly in the afternoon and more northerly later Thursday night.
  • The strong northerly winds into Friday the 6th resulted in rapidly building waves across the southern part of Lake Michigan, reaching an estimated 15+ ft along parts of the northwest Indiana shore, and at least occasionally reaching 10+ ft along the Illinois shore including Chicago.
  • Lakeshore flooding resulted in parts of southern Cook County and northwest Indiana. Some of this was caused damage in northwest Indiana as relayed in media reports.
  • The potential for lakeshore flooding was mentioned in NWS graphics as early as Monday the 2nd, and a Lakeshore Flood Watch was issued Wednesday the 4th. This was upgraded to a Warning for northwest Indiana early Thursday morning and for central and southern portions of the Cook County shore on Thursday evening.
