London immobilized after worst storm in 18 years

London was immobilized Monday by the biggest snow storm to hit the city in 18 years, according to the Britain's Meteorological Office.

Air and ground transportation were slowed significantly as the snow reached four to six inches in some parts. Unprecedented traffic jams were seen in several highways near London and the city's underground and rail transportation continued to suffer from disruptions.

The storm which began Sunday night left most of London and southeast England paralyzed. Shops, schools and courts shut down.

Airports re-opened on Monday afternoon but with less flight schedules, according to reports.

The Met Office has issued an extreme weather warning for England, Wales and parts of eastern Scotland.
