The Los Angeles region is bracing for a series of potential thunderstorms and heavy snowfall this week with additional winter storms predicted for the following week, according to the National Weather Service.

There was heavy snowfall, occasional blizzards and a biting easterly wind.

Officials said rescue operations were continuing in extreme weather amid heavy snowfall.

In a stable climate, they remain roughly the same size, gaining about as much ice through snowfall as they lose through melting.

Toronto Pearson Airport had been experiencing weather-related delays over the last few days, with heavy snowfall and freezing temperatures battering parts of Ontario.
