Winter Temporary Weather Havens
For individuals needing to escape adverse cold conditions (real or wind chill air temperature at 20 degrees or below) before continuing on their destination; temporary weather havens are available.  These sites are for all Washtenaw County residents and will be activated when the weather reaches extreme temperatures, requiring public school closings. Temporary weather havens are identified through outreach to public and private human services providers, county government, and local hospitals who are asked to volunteer their space for residents in need of a warm place during severe cold weather.  A current list of weather haven locations and hours are available here.

Wireless Emergency Alerts
Mobile devices are an important communications tool that can be used to alert people as soon as possible that their lives or property are seriously at risk.

CTIA and the wireless industry, along with the Federal Communications Commission (FCC) and Federal Emergency Management Agency (FEMA), developed the Wireless Emergency Alerts (WEA) to send concise, text-like messages to users’ WEA-capable mobile devices. This ensures as many Americans as possible are alerted to the dangerous situations.
