雪灾给安大略部分地区带来突然的、危险的冬季天气,引发警报和安全警告。 Snow squalls bring sudden, dangerous winter weather to parts of Ontario, prompting alerts and safety warnings.

雪阵雨是短暂而强烈的暴雪爆发，伴有强风，有时还会有闪电，持续时间不到一小时，由冷空气穿越温暖的五大湖或冷锋引起。 Snow squalls are short, intense bursts of heavy snow with strong winds and sometimes lightning, lasting less than an hour, caused by cold air moving over warm Great Lakes or cold fronts. 它们可严重降低能见度并造成危险的驾驶条件,即使在传统雪带区域以外的地区,如多伦多,视风向和风速而定。 They can severely reduce visibility and create hazardous driving conditions, even in areas beyond traditional snowbelt regions like Toronto, depending on wind direction and speed. 加拿大环境部为安大略中部和北部受影响地区发布警报,建议居民在极端寒冷期间留在室内,防范冻伤,并监测天气最新情况。 Environment Canada issues alerts for affected areas in central and northern Ontario, advising residents to stay indoors during extreme cold, protect against frostbite, and monitor weather updates.
