DETROIT (AP) — Michigan residents are bracing for temperatures to dive further to dangerously cold levels as they dig out following a multi-day storm that has shuttered schools and government offices.

The National Weather Service says that as of Monday morning 16.2 inches of snow fell in Flint, 15.5 inches fell north of Jackson, 15.4 inches fell at Howell and 15 inches was reported north of Battle Creek.

Roads are slippery, with numerous crashes. Authorities say weather is a factor in at least two roadway deaths over the weekend.

In the southern Lower Peninsula, temperatures are to drop late Monday or early Tuesday as low as minus 15. Temperatures Monday morning are in the teens in Detroit. A reading of 22 degrees below zero was reported in the Upper Peninsula community of Ironwood.
