Notre Dame Warnings, Watches and Advisories

Do not drive vehicles through flooded areas. The water depth or fast flowing water/mud/debris from a flash flood will make road conditions unsafe. Do not rely soley on data presented here or other third-party websites - always check your official national and local weather service agency website, socials, radio and/or TV stations for making critical decisions related to weather events.

Please carefully read each posted Warning and Alert as it relates to the area(s) being affected. We may provide a wider range of issued severe weather warnings for surrounding cities and counties, so some alerts may not directly impact this location. This is done to help with preparing for severe weather that may overlap or be heading towards Notre Dame.

Special Weather Statement issued January 18 at 3:28PM EST by NWS Louisville KY

A quick-moving system will bring an area of light snow showers to the region late tonight into early Sunday morning. Minor snow accumulations up to around an inch are possible. Breezy winds late Sunday morning into Sunday afternoon combined with snow could lead to reduced visibility in the heaviest snow showers. Additionally, sub-freezing temperatures could allow for slick spots and light snow accumulations on untreated surfaces.

Extreme Cold Watch issued January 18 at 3:16PM EST until January 22 at 10:00AM EST by NWS Northern Indiana

* WHAT...Dangerously cold wind chills between 15 and 25 below zero possible. * WHERE...Portions of northern Indiana, southwest Michigan, and northwest Ohio. * WHEN...From late Sunday night through Wednesday morning. * IMPACTS...The dangerously cold wind chills as low as 20 below zero could cause frostbite on exposed skin in as little as 30 minutes. Frostbite and hypothermia will occur if unprotected skin is exposed to these temperatures. * ADDITIONAL DETAILS...A period Monday into Monday night will be able to warm into the single digits below zero which provides additional uncertainty around wind chill magnitude. Time duration of this relatively warm period and individual alignment of wind and temperatures during the watch period are still uncertain. Lake effect snow and accompanying cloud cover will also impact wind chills during this time period insulating them like a blanket and keeping those areas relatively warm.

Hydrologic Outlook issued January 18 at 9:12AM CST by NWS Chicago IL

ESFLOT Favorable conditions for river ice development and possible ice jams are expected tonight through early next week, impacting the Rock, Fox, Des Plaines, and Kankakee river basins. Bitterly cold temperatures will return to the region tonight and persist through early next week. This will make conditions favorable for the rapid formation of river ice on area rivers and tributaries. River ice spotters and river gauge data indicate that most area rivers already have some areas of heavy river ice including a few minor ice jams. New ice jams will be possible along the Rock, Fox, Des Plaines, and Kankakee rivers, including their tributaries. Any ice jam that develops will have the potential to cause rises on area rivers with little warning and isolated areas of flooding are possible. This outlook means that elevated water levels and potential impacts are possible, but not yet certain. Persons along area rivers should continue to monitor the latest forecasts into next week. This product will be updated by Sunday afternoon.
