Snow or freezing precipitation

The emergency response plan (PIU) in the event of extreme weather conditions defines the actions the government should take in the event of six different weather conditions, including snow or freezing precipitation.

Orange vigilance - moderate snow or ice warning

between 11 and 25 cm of snow in 12 hours or freezing precipitation across the country

The possible consequences include:

• large quantities of snow or ice for the region concerned;
• very difficult traffic conditions throughout the network, in particular in wooded areas (trees may fall);
• increased risk of road traffic accidents.

Red vigilance - heavy snow or ice warning

more than 25 cm of snow in 12 hours or freezing precipitation across the country based on expected damage

The possible consequences include:

• substantial snowfall or ice which could seriously affect economic life and human activity;
• roads that swiftly become impassable over the whole network;
• a very great risk of air and rail traffic disruptions.

In the event of freezing precipitation:

• significant risk of damage to the high voltage electricity distribution networks.
