Frost/Freeze Products Begin May 19th for Northern Lower

Temperatures throughout the spring months have been quite cold all throughout northern Michigan, with vegetation roughly 2 to 3 weeks behind schedule. However, recent rains and some warmth have resulted in the beginning of the growing season, with sensitive plants becoming more vulnerable to freezing temperatures. As such, the National Weather Service will begin issuing frost and freeze products (frost advisories and/or freeze warnings) for all of Northern Lower Michigan on Monday, May 19th.

These products will begin at a later date for Eastern Upper Michigan.

If you have any questions about this, please contact Jim Keysor at (989) 731-3384.
