A yellow freezing rain warning in Canada means freezing rain is expected to create hazardous conditions and moderate, localized or short-term impacts. Rain that freezes on contact with cold surfaces can cause ice to accumulate on roads, sidewalks, trees and other exposed surfaces.
Even small amounts of ice can make driving and walking dangerous. Depending on the amount and duration of freezing rain, conditions may also lead to transportation disruptions, fallen branches and power outages.
What Is a Yellow Freezing Rain Warning?
In simple terms, a yellow freezing rain warning means ice accumulation may make roads, sidewalks and other exposed surfaces slippery and dangerous. Travel delays and localized disruptions may occur, while ice can also accumulate on trees, branches and power lines.
The severity of the conditions depends on factors such as the amount and duration of freezing rain, surface temperatures and local conditions. Even relatively small amounts of ice can make driving and walking hazardous.
When a yellow freezing rain warning is issued, monitor current weather and road conditions, allow additional travel time and take extra care when driving or walking outdoors.
How Serious Is a Yellow Freezing Rain Warning?
A yellow freezing rain warning can create hazardous conditions, particularly for drivers and people walking outdoors. Ice accumulation can make roads, sidewalks, parking lots and other exposed surfaces slippery and difficult to navigate.
Although yellow represents a lower level of potential impact than orange, freezing rain can still cause dangerous conditions. Vehicle collisions, slips and falls, transportation delays and localized disruptions may occur.
The seriousness of a yellow freezing rain warning depends on factors such as the amount and duration of freezing rain, surface temperatures and local conditions. Even relatively small amounts of ice can create significant hazards, particularly on untreated roads and sidewalks.
People in affected areas should monitor current weather and road conditions, allow additional travel time and take extra precautions when driving or walking outdoors.
Yellow Freezing Rain Warning vs Orange Freezing Rain Warning
A yellow freezing rain warning indicates a lower level of potential impact than an orange freezing rain warning.
Yellow warnings indicate the potential for moderate, localized or short-term impacts, including slippery roads and sidewalks, hazardous travel and localized disruptions. Orange warnings indicate that freezing rain is expected to cause more significant impacts that may be major, widespread or prolonged.
Can a Yellow Freezing Rain Warning Be Upgraded to Orange?
Yes. A yellow freezing rain warning can be upgraded to orange if conditions worsen and more significant impacts are expected. This may occur when forecast changes indicate the potential for greater ice accumulation, more widespread disruptions or more serious effects on transportation and infrastructure.
Yellow Freezing Rain Warning vs Red Freezing Rain Warning
There is no red freezing rain warning in Canada’s colour-coded weather alert system. The applicable warning levels for freezing rain are yellow and orange.
Yellow indicates the potential for moderate, localized or short-term impacts, while orange represents the highest freezing rain warning level and indicates the potential for significant impacts that may be major, widespread or prolonged.
Can a Yellow Freezing Rain Warning Be Upgraded to Red?
No. A yellow freezing rain warning cannot be upgraded to red because there is no red warning level for freezing rain. A yellow warning may be upgraded to orange if more significant impacts are expected.
Yellow Warning – Freezing Rain FAQs
A yellow freezing rain warning means freezing rain is expected to create hazardous conditions and moderate, localized or short-term impacts. Ice may accumulate on roads, sidewalks, trees and other exposed surfaces.
Driving may be possible during a yellow freezing rain warning, but roads can become slippery and hazardous. Drivers should check current road conditions, reduce their speed, increase following distance and allow additional travel time.
A yellow freezing rain warning can create dangerous travel and walking conditions. Even relatively small amounts of ice can increase the risk of vehicle collisions, slips and falls, transportation delays and localized disruptions.
The amount of ice accumulation varies depending on the intensity and duration of the freezing rain, surface temperatures and local conditions. Check the specific warning issued for your area for forecast details.
Yes. Ice can accumulate on trees, branches and power lines, adding additional weight that may contribute to damage and power outages. The risk generally increases with greater ice accumulation and prolonged freezing rain.
A yellow freezing rain warning can be upgraded to orange if more significant impacts are expected. It cannot be upgraded to red because there is no red warning level for freezing rain in Canada’s colour-coded weather alert system.
