Ice storms By shirali padaliya

Ice storms form when a layer of warm air is between 2 layer of cold air. Frozen precipitation melts while falling into the warm layer, and then it proceeds to refreeze in the cold layer above the ground. This creates freezing rain or a glaze ice.
- Get an emergency supply kit. Update family emergency supply kit that includes :- rock salt, sand to improve traction, some snow removal equipments, and adequate clothing and blankets to keep warm. Make family emergency plan and include how to get back in ease of emergency. Plan places of where to meet in/outside neighborhood. When a winter STORM WARNING is issued, stay indoors during the storms
Supply/Emergency kit should contain :- 3 day water supply, Non perishable food, flashlight, battery, first aid kit, 7 day medication supply, multi purpose tools, sanitation items, cell phones with chargers, family emergency contact information, extra cash, warm clothing, baby supplies and pet supplies(if you have any).
The ice storm of 1998 was one of the largest disaster in Canadian history. Between 4 - 10 January 1998, sections of the St.Lawrence Valley from Kingston to Québec's Eastern Twonship received up to 100 mm of ice pellets and freezing rain - more than double the ice precipitation normally in those area in a whole year. The storm claimed as many as 35 lives, injured 945 and, resulted in the temporary displacement of 600,000 people. Massive power outages occurred cutting off electricity for nearly 1.4 million customers in Québec and over 240,000 in eastern Ontario. The total financial cost of the storm was estimated at $5.4 billion.

When meteorologists forecast a winter storm one of the important predictions they make is the type, or types, of precipitation that are likely to fall.Will freezing rain cause an ice storm? Will ice pellets called sleet leave the ground covered in slush? Will it rain or snow? To answer these questions, they look at the temperature of air masses in the storm.When a warm air mass is pushed above a cold air mass with freezing temperatures, various types of icy precipitation can form. This type of collision of air masses is called a warm front. If the cold air mass is thick, raindrops will freeze into ice pellets called sleet. Sleet pellets are smaller than snowflakes and do not have crystal shapes. If the cold air mass is thin, the rain will be super-cooled on its way down allowing it to freeze instantly when it gets to the ground leaving a layer of ice. This super-cooled rain is called freezing rain, and the resulting icy conditions are often called an ice storm. If the cold air mass near the ground moves out of the way, then the rain will not freeze as it falls. If the warm air mass moves out of the way and it is cold between the storm clouds and the ground, then snowflakes will fall. A single winter storm can produce several different types of precipitation - sleet, ice, show, and rain - as the air masses change and move during the storm.
