NWS Detroit/Pontiac will no longer issue Frost Advisories or Freeze Warnings as of October 21 2017
for the remainder of the cold season.  The growing season has come to an end across Southeast 
Lower Michigan. While Southeast Lower Michigan has yet to receive a killing freeze, the lowering 
sun angle has all but ended the growing season across the region.  In addition, we have reached 
the climatological average for first freeze for most locations across Southeast Lower Michigan.  
Frost Advisories and Freeze Warnings will be issued again at the start of the next growing 
season in the Spring of 2018.
