ICE STORMS!! By: Casey Searl and Gillian Manantan

What is an Ice Storm? An ice storm is a type of winter storm characterized by freezing rain- cold ground, conditions can become dangerous. Cold rain freezes as it touches the ground and other surfaces

How are Ice Storms Produced? Ice storms typically begin with snow and strong easterly winds conditions well ahead of an approaching warm front. The snow, however, changes briefly to sleet and then to rain that freezes on impact, coating all exposed surfaces with a growing layer of ice.

Why are Ice Storms classified as severe Weather? Driving becomes extremely hazardous causing devastating car crashes and pile ups. pedestrians are severely affected sidewalks and stairs become slippery, Power lines and trees fall due to ice/ lose of power

Where/when do ice storms occur? The North American Ice Storm of 1998 was a massive Ice Storm that struck a relatively narrow swath of land from Eastern Ontario to southern Quebec to Nova Scotia in Canada, and bordering areas from Northern New York in January It caused massive damage to trees and electrical infrastructure all over the area, leading to widespread long term power outages. Millions were left in the dark for periods varying from days to weeks, leading to more than 30 fatalities, a shut down of activities in large cities like Montreal and Ottawa and an unprecedented reconstruction effort of the power grid. Ice Storms usually happen in the north and could strike in a snow storm.
