A yellow weather warning is the lowest level of alert from Environment and Climate Change Canada. It means conditions could be hazardous, but are not extreme. You should stay informed and plan for possible delays or minor disruptions, especially if you are driving or spending time outdoors.
What does a yellow weather warning mean?
A yellow warning signals that weather may cause local disruptions. For snow, it often means 10–15 centimetres possible. For rain, it means steady precipitation that could cause ponding on roads. The key is that the event is manageable — not dangerous for most people — but still worth paying attention to if you have travel or outdoor plans.
Yellow vs orange weather warning: which is worse?
Orange is worse. An orange warning means severe weather is likely — for example, heavy snow or freezing rain. Yellow is a heads-up. Orange is a call to change plans. Knowing the difference helps you decide whether to proceed normally or take precautions.
What should you do during a yellow weather warning?
Check local weather conditions and daily 10 day forecast before heading out. Drive slower than usual, especially on highways. If the warning is for rain, watch for standing water in low areas. No need to cancel events, but allow extra time.
What does yellow warning snowfall mean?
It means Environment Canada expects 10 to 15 centimetres of snow over 12 hours. Roads may become slushy and visibility can drop briefly. Plows will be out, but expect slower commutes.
What does yellow warning rainfall mean?
It means steady rain with totals of 25 to 50 millimetres in 24 hours. Low-lying areas and poor drainage spots may flood. Driving through deep water is not recommended.
Is a yellow weather warning serious?
Not usually. It is an advisory, not a danger call. Most people will notice only minor delays. However, it is a good time to check weather warning updates in your area.
