The METAR code for freezing rain is FZRA. A storm that produces a significant thickness of glaze ice from freezing rain is often referred to as an ice storm . Although these storms are not particularly violent, freezing rain is notorious for causing travel problems on roadways, breaking tree limbs, and downing power lines from the weight of ...
Freezing rain advisory WSW (alt.: freezing drizzle advisory) – Freezing rain or freezing drizzle producing ice accretion of up to 1 ⁄ 4 inch (6.4 mm) that may cause significant travel impairments is expected or occurring. Discontinued on October 2, 2017; a winter weather advisory for freezing rain is now issued instead.
Freezing rain sometimes marks the southern edge of wintry precipitation in weather systems. That southern edge can dip into areas not used to dealing with wintry weather, such as the South.
The criteria for this warning vary from state to state, but typically an ice storm warning will be issued any time more than 1 ⁄ 4 inch (6.4 mm) of ice at peak is expected to accumulate in an area, else a freezing rain or drizzle advisory is issued; in some areas, the criterion is 1 ⁄ 2 inch (13 mm) instead.

Liquid forms of precipitation include rain and drizzle and dew. Rain or drizzle which freezes on contact with a surface within a subfreezing air mass gains the preceding adjective "freezing", becoming the known freezing rain or freezing drizzle. Slush is a mixture of both liquid and solid precipitation.
The northeast is also expected to see some freezing rain on Saturday, forecasters said. "Any amount of ice could lead to dangerous travel" on Saturday morning, the weather service in New York said.
An ice storm, also known as a glaze event or a silver storm, is a type of winter storm characterized by freezing rain. [1] The U.S. National Weather Service defines an ice storm as a storm which results in the accumulation of at least 0.25-inch (6.4 mm) of ice on exposed surfaces.
Freezing rain occurs when the wedge of warm air aloft is much thicker, allowing the raindrop to survive until it comes in contact with the cold ground. A coating of ice forms on whatever the ...
