Over 1300 customers in Door and Kewaunee Counties remain in the dark Monday after Sunday's winter storm knocked out the power for thousands of Wisconsin Public Service customers. It is a drastic improvement from Sunday afternoon when at around 1:30 p.m. nearly 4900 customers were without power. The most affected area remains to be situated in northern Door County where hundreds of residents in Sister Bay, Ephraim, and Baileys Harbor were still without power as of 6:30 a.m. Monday. The extended period of time without heat has forced the Sister Bay/Liberty Grove Fire Department to turn its fire station on Mill Road into a warming shelter until the power returns potentially this afternoon. You can find more details about the warming shelter below.
