Lansing, Michigan – Residents across Michigan should be prepared for sudden loud cracking or booming sounds Friday as lingering Arctic cold renews the risk of the “exploding tree” phenomenon, particularly across western parts of the state.
According to the National Weather Service, subzero temperatures combined with bitter wind chills Friday morning are creating ideal conditions for frost cracking, also known as cryoseismic booming. This occurs when sap inside trees freezes rapidly and expands while the outer wood contracts, causing intense internal pressure that can split trunks suddenly with a sharp, explosive sound.
The risk is highest in Western Michigan, including areas from Muskegon and Holland through Grand Rapids, Big Rapids, and inland toward Mount Pleasant. Prolonged cold near Lake Michigan and inland hardwood forests continues to stress mature trees, increasing the likelihood of cracking during the coldest pre-dawn hours. Parts of central and southern Michigan, including the Lansing and Kalamazoo areas, may also experience isolated events.
While exploding trees are uncommon, splitting trunks and falling limbs can damage vehicles, sidewalks, roofs, and power lines. Residents are advised to avoid standing beneath large trees during extreme cold and to park vehicles away from tree-lined streets when possible.
The same cold driving tree stress also increases the risk of frostbite on exposed skin within minutes, frozen pipes, and vehicle issues. Officials urge limiting outdoor exposure Friday, wearing insulated layers, covering all exposed skin, and keeping pets indoors. Cold-related advisories remain in effect, with additional updates possible if conditions persist.
