What do you tune in during severe weather? Twitter’s #miwx hashtag is useful, as is the amateur radio SKYWARN service which in Ann Arbor and Washtenaw County uses the N8DUY repeater on 145.15. If you don’t have a ham radio, you can tune in to that repeater via Broadcastify.

Of course, no storm would be complete without a watch for power outages. My big list of power outage maps can be helpful; you will want to be watchful for DTE Energy,Consumers Energy, and Indiana Michigan Power outage maps in southern Michigan.
