A WEATHER warning for ice has been upgraded to amber, as freezing rain looks set to cause "very dangerous travelling conditions".

The amber warning, which will last from 10am on Saturday until 6am on Sunday, warns of freezing rain which will cause widespread ice.

The Met Office said: "Freezing rain is expected to result in the rapid development of widespread ice, with very dangerous travelling conditions likely."

It said injuries from slipping and danger to life on icy surfaces are likely, and pavements and cycle paths are likely to become "instantly impassable because of the sudden formation of black ice".

Quickly forming black ice may also affect bus, train and air travel, and driving conditions are also likely to become dangerous, leading to a greater chance of crashes, road closures and increased journey times.

Powercuts and interruptions to phone coverage may also take place.

A yellow warning for snow and ice, which runs from 9am tomorrow until 9am on Sunday, remains in place.

The Met Office chief forecaster said: "Heavy freezing rain is expected to develop during Saturday.

"This will result in the rapid formation of widespread ice on roads, pavements, trees and other structures.

"Freezing rain is rare in the United Kingdom but when it does occur the impacts can be very severe. This is due to the fact that it can form very quickly, it can be difficult to see and is incredibly slippery.

"Some sleet and snow is possible over the very highest ground and the freezing rain may also be followed by a spell of sleet and snow as the precipitation clears from the west.

"The freezing rain and sleet and snow will be accompanied by strong southeasterly winds which will pose an additional hazard to travel, in particular over high ground."
