The National Weather Service Offices across the region have begun scheduling Spotter Trainings with local county emergency managers.
I threw the map (to the left) together that roughly shows where classes have already been posted. By visiting the page (I've added the links below) that corresponds to the respective NWS Office, you can find out more details (i.e. Where & When) about each training. Nothing has been posted concerning NWS Marquette.
