A yellow winter storm warning in Canada means a combination of hazardous winter weather may cause moderate, localized or short-term impacts. Snow, ice and strong winds can create difficult travel conditions, transportation delays and disruptions to daily activities.
The severity of the impacts depends on the combination, intensity and duration of the expected conditions. This guide explains what a yellow winter storm warning means, how serious it is, the potential impacts and what you should do when one is issued.
What Is a Yellow Winter Storm Warning?
A yellow winter storm warning means a combination of hazardous winter weather is expected to cause moderate, localized or short-term impacts. Conditions may include snow, freezing rain, ice and strong winds.
Winter storms can create multiple hazards at the same time, resulting in difficult travel conditions, reduced visibility and transportation disruptions.
When a yellow winter storm warning is issued, people should monitor current conditions, prepare for possible travel delays and take precautions based on the specific combination of winter hazards expected.
How Serious Is a Yellow Winter Storm Warning?
A yellow winter storm warning can create hazardous conditions because multiple types of winter weather may occur during the same event. Snow, freezing rain, ice and strong winds can affect travel and daily activities.
The seriousness of the warning depends on the combination, intensity and duration of the expected conditions. Multiple hazards occurring together may create greater disruptions than a single type of winter weather.
People should monitor current conditions, prepare for possible transportation delays and take precautions based on the specific hazards expected.
Yellow Winter Storm Warning vs Orange Winter Storm Warning
A yellow winter storm warning indicates the potential for moderate, localized or short-term impacts, while an orange winter storm warning indicates that significant impacts are likely.
Yellow warnings may involve hazardous travel and disruptions caused by snow, ice or strong winds. Orange warnings indicate the potential for more serious or widespread impacts, including major transportation problems and prolonged disruptions.
Yellow Winter Storm Warning vs Red Winter Storm Warning
A yellow winter storm warning represents the lowest level of potential impact, while a red winter storm warning represents the highest level in Canada’s colour-coded weather alert system.
Yellow warnings may create hazardous conditions and localized disruptions. Red warnings indicate very dangerous conditions and significant, widespread impacts that may make travel extremely difficult or impossible and cause major disruptions to infrastructure and essential services.
