Heavy, wet snow accumulates on power lines and tree branches, causing them to snap under the weight and leading to widespread power outages. Flying debris, such as loose garbage cans, signs, or broken tree limbs, becomes projectiles in the high winds, posing a serious threat to people, vehicles, and windows.
Blizzard Infrastructure Failure: How Snow and Wind Compromise Structural Integrity
Structural Damage and Property Hazards The physical force of a blizzard can cause direct structural damage to buildings and property. Beyond the weight of snow and ice accumulation, the powerful winds associated with these storms can exert significant pressure on structures, leading to roof damage or even partial collapses, particularly on older or poorly maintained buildings.
Defined by a combination of sustained winds or frequent gusts of 35 miles per hour or greater, and blowing snow that reduces visibility to less than a quarter mile for a duration of three hours or more, these storms create hazardous conditions that impact safety, infrastructure, and public health. These outages can disable heating systems in homes and businesses, disable sump pumps, and disrupt communication networks.
Blizzard Infrastructure Failure: Causes and Risks
Blizzards are far more than picturesque scenes of snow swirling against a winter sky; they represent a serious meteorological phenomenon capable of disrupting entire regions. The danger doesn't end when the storm passes, as melting snow can lead to flooding and the refreezing of surfaces creates treacherous, slick conditions.
