Civil Protection’s recommendations to citizens in view of bad weather

The Civil Protection is making recommendations to citizens, in view of the worsening weather, to be particularly careful, ensuring that they take measures to protect themselves from the risks arising from the onset of severe weather phenomena.

The General Secretariat of Civil Protection (civilprotection.gov.gr) of the Ministry of Climate Crisis and Civil Protection has informed the relevant government departments involved, as well as the regions and municipalities of the country, in order to be in increased readiness for civil protection, in order to deal immediately with the effects of the outbreak of severe weather phenomena.

At the same time, according to a statement by the Fire Department, operational plans are being implemented to address the risks of flooding and snowfall and their accompanying phenomena, while the Fire Services of the areas where the phenomena are expected to occur have been put in a state of increased readiness and further escalation if required, in order to immediately address any problems.

In particular, in areas where heavy rainfall, thunderstorms or gusty winds are expected, the General Secretariat of Civil Protection recommends that citizens:

* To secure objects which, if carried away by severe weather phenomena, may cause damage or injuries.

* Ensure that residential gutters and downspouts are unclogged and functioning properly.

* Avoid crossing streams and creeks, on foot or by vehicle, during storms and rainstorms and for several hours after they have ended. Particular attention is needed at road crossings where the road crosses streams and there is no bridge.

* Avoid outdoor work and activities in marine and coastal areas during the outbreak of severe weather events (risk of lightning strikes).

* Take shelter immediately during a hailstorm. Take shelter in a building or car and do not leave the safe area until they are sure the storm has passed. Hail can be very dangerous for animals as well.

* Avoid crossing under large trees, under posted signs, and generally from areas where light objects (e.g., pots, broken glass, etc.) can become detached and fall to the ground (e.g., under balconies).

* Strictly follow the instructions of the local authorities, such as traffic police etc.

In areas where snow and frost is forecasted:

If they are to travel by car:

* To be informed about the weather and the condition of the road network

* Have anti-slip chains and a full tank of fuel in their vehicle

* Travel, if necessary, preferably during the day, preferably on main roads

* Inform their relatives about the route they are going to take

* Use the main roads as much as possible

* To change their travel schedule in order to avoid the peak of the weather

* To follow strictly the instructions of the local authorities, such as the traffic police, etc.

If moving on foot:

* Dress in several layers of light clothing instead of one heavy garment and wear appropriate shoes to avoid injuries due to slipperiness

* Avoid unnecessary travel during peak weather conditions (heavy snowfall, freezing conditions)
