London (and the rest of UK) got one of the worst snow storms in the last two decades. Travel was hit the worst with canceled trains, canceled buses, canceled flights and "miles of tailbacks on motorways". Heathrow had the worst day for flights with regards to delays and cancellations since September 11 2001. Some areas of London saw 8 inches of snow. For a city which boasts one the best and well-used public transportation system (train, tube and buses), the city is in utter chaos.

And it is still not over. Sources say that there is more snow to come.

From BBC News -

Further snowfall in northern England and the Pennines could be made worse by strong winds which will cause snow to drift, he added.

In the late afternoon, more heavy snow is forecast to hit the eastern part of England, including East Anglia, London and the Home Counties, accompanied by strong winds. This will work its way up through the Midlands, northern England and eastern Scotland.

Monday evening will see the snow falling briefly to sleet in East Anglia and the south-east of England, before it freezes.

Parts of the Midlands, East and South will experience temperatures between -4C and -7C on Monday night

"Our message is still don't travel unless your journey is essential," a spokeswoman for the Highways Agency said. "If you do have to travel, be prepared".

The weather will turn icy by the Tuesday morning, making road travel treacherous and pavements hazardous.
