A triple threat of rain, sleet and snow caused dangerous driving conditions and several accidents across Long Island Friday.

The snow, rain and sleet continued throughout the day, with about 1 to 4 inches of an icy mix of accumulation. Road crews were prepared for the worst, and had been out salting and sanding area roadways since the early morning hours.

The storm caused hundreds of cancellations at Kennedy airport. JetBlue alone has canceled more than 200 flights at JFK due to the snow. There have also been a handful of power outages across the Island, mostly in the Lake Ronkonkoma and Franklin Square area. Click here for the latest News 12 Long Island weather update.
