Under the storm-in-progress rule, a property owner or a tenant in possession will not be held responsible for accidents caused by snow or ice that accumulates during a storm until an adequate period of time has passed following the cessation of the storm to allow an opportunity to ameliorate the hazards caused by the storm. However, once a landowner or a tenant in possession undertakes snow removal during a storm in progress, it must act with reasonable care so as to avoid creating a hazardous condition or exacerbating a natural hazard created by the storm. The mere failure of a defendant to remove all the snow and ice, without more, does not establish that the defendant increased the risk of harm.
