LONDON, Feb. 1 (UPI) -- Heavy snow fell over much of England and Wales Saturday, messing up travel by ground and air, officials said.
What could turn out to be the region's heaviest and most widespread snowfall in six years was expected to clog roads and force schools to close Monday, the BBC reported.
Forecasters said up to 6 inches of snow could pile up overnight in Kent, London, Surrey and Hampshire, the British network said.
An unidentified driver said several trucks had jack-knifed on the M25 highway and the M20 was closed at Kent because of treacherous conditions. Buses were pulled off the streets of London, as well.
A BAA spokesman said the runway at London Gatwick Airport was closed for two hours, forcing the cancellation of 23 flights and the diversion of 18 to other airports. Train and taxi service out of the airport also was at a standstill.
London City Airport also closed temporarily while the runway was de-iced.
Heathrow or Stansted airports reported normal activities.
