Michigan Ice Storm Slams Houghton Lake, Cadillac and St. Helen as Freezing Rain Knocks Out Power to 90,000 Residents
MICHIGAN — A dangerous ice storm is causing widespread damage across north-central lower Michigan early Monday morning, where freezing rain and sleet have coated trees and power lines and left around 90,000 residents without electricity statewide.
The heaviest icing has been reported along the M-55 corridor, where communities are experiencing accumulating ice that is snapping branches and bringing down power lines as precipitation continues through the morning hours.
Major communities currently facing the worst conditions include Houghton Lake, Cadillac, St. Helen, and Harrisville, where thick ice buildup is already being reported.
Ice Accumulation Continues to Grow
Storm reports indicate that ice totals are already approaching around 0.3 inches, with some locations potentially nearing 0.4 inches of accumulation as of approximately 1:45 a.m. EDT Monday (March 16, 2026).
This level of icing is enough to cause significant stress on trees and utility infrastructure, especially as freezing rain continues to fall across the region.
Emergency officials warn that even small increases in ice accumulation can dramatically increase the likelihood of:
- Falling tree limbs
- Downed power lines
- Road hazards
- Expanding power outages
Power Outages Climbing Across the State
Power outage numbers have climbed rapidly overnight, with approximately 90,000 customers without electricity across Michigan.
Many of those outages are concentrated across north-central lower Michigan, where the heaviest freezing rain has occurred.
Communities along and near the M-55 corridor, including areas surrounding Cadillac and Houghton Lake, appear to be among the hardest hit by the ice storm.
As freezing rain continues, officials expect outages could increase further through the morning.
Tree Damage and Falling Limbs Becoming Major Hazard
The weight of the ice is already producing widespread tree damage, with limbs breaking and falling in several areas.
Authorities warn residents to stay indoors and avoid areas near exterior walls, where falling branches could potentially damage structures.
Trees weakened by ice may continue to break even after precipitation slows, meaning hazards could persist for several hours after the storm.
Travel and Safety Concerns Across the Region
In addition to tree damage and outages, roads across north-central Michigan are becoming slick and hazardous due to freezing rain and sleet accumulation.
Motorists traveling through areas near Houghton Lake, St. Helen, Harrisville, and Cadillac are being urged to use extreme caution.
Emergency management officials are advising residents to limit travel and remain indoors where possible until conditions improve.
Freezing Rain Expected to Continue Through Morning
Forecasters say freezing rain may continue through the remainder of the morning, meaning additional ice accumulation is still possible before temperatures begin to change later in the day.
As long as freezing precipitation persists, the risks of additional outages, falling trees, and dangerous travel conditions will remain elevated.
