New York ( CNN ) -- A pregnant woman was killed Thursday after being struck by a privately owned tractor clearing snow in a parking lot , but her baby boy was delivered by cesarean section , authorities said . The nearly full-term boy -- weighing 6.6 pounds -- was in critical condition at Brooklyn 's Maimonides Medical Center , where his 36-year-old mother was pronounced dead on arrival after being struck as she was loading groceries into her car . The victim was identified as Min Lin , a Brooklyn resident , police said . Lin arrived at the hospital within 10 minutes of the accident , and the baby was delivered in less than a minute , hospital spokeswoman Eileen Tynion said . Police said the Bobcat compact tractor equipped with a snowplow was backing up and struck the woman about 10:40 a.m. in a parking lot in the rear of Fei Long Market . Her husband was with her . The 42-year-old operator of the private snowplow was being questioned , police said . The incident occurred during New York City 's sixth winter storm of the season . The latest storm was expected to dump up to 14 inches on some parts of the city . Fast-falling snow caused tractor-trailers to jacknife and prompted state authorities in New York to ban commercial traffic on Interstate 84 , a major east-west highway . Storm sweeps north .
