Storms

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 storms.

Orange vigilance - heavy storm warning

hail between 1 and 3 cm, gusts of wind between 90 and 110 km/h or rain between 25 and 35 l/h and CAPE (Convective Available Potential Energy) 1000-2500 J/kg

The possible consequences include:

• significant localised damage to light housing and temporary structures;
• rapid localised flooding of caves and low-lying ground;
• possibility of fires starting as a result of lightening not accompanied by rain;
• considerable material damage or risk of accidents following strong gusts of wind or hail.

Red vigilance - violent storm warning

hail above 3 cm, gusts of wind exceeding 110 km/h or rain over 35 l/h and CAPE (Convective Available Potential Energy) above 2500 J/kg

The possible consequences include:

• several very violent storms, with large hailstones and destructive gusts of wind;
• very significant localised damage to homes, parks, crops and plantations;
• very serious localised damage to forests;
• a risk of fire following a large number of lightening strikes;
• danger to light accommodation and temporary structures;
• flooding of caves and low-lying areas;
• very high water levels around streams and small rivers.
