Good morning. Bundle up on your way out, most areas had a freezing start to the day with cold wave advisories re-issued in some areas. Seoul also had a low of minus 10 degrees Celsius but felt more like minus 15... but it was nice to breathe in some fresh, clean air.

The sudden drop in temperatures can make many come down with colds and flu... so dress warmly and turn on the humidifier as the air is getting drier too.

What's more, biting winds are making things colder. Daily highs will be 3 to 4 degrees lower than yesterday, Seoul will only see a high of minus 1 degree, but fresh air will be with us throughout the day.

Despite icy cold temperatures, be sure to open the windows and let the fresh air in today because with a rise in temperatures expected for Thursday, it's likely we'll see another round of bad air in most areas.

Highs will be hovering around 5 degrees in Seoul... many would agree that this winter has been milder than average so far, in fact, we could see a similar weather pattern for another 5 days or so.

That's Korea for you and here's the international weather for viewers around the world.
