Risk maps

Risk

Risk (last 24h)

These maps show the distribution of weather related risk conditions (temperature, wind, precipitation) of the previous 24 hours. Each weather event is visualised with a specific colour as shown in the map legend.

Frost

Danger of frost is shown by a blue surface on the map. Risk of frost occurs, when the air temperature (at 2 m height) sinks below the freezing point of 0°C for at least one hour during the indicated period. Frost in connection with precipitation is counted as snow.

Wind

There are 3 levels for wind risk, which are represented in different colours on the maps. A wind risk is indicated, if within the indicated period, the gusts of wind in the selected area exceed the threshold speed during at least one hour. The following stages are valid:

  • Yellow: Gusts of wind with a speed of over 50 km/h.
  • Orange: Gusts of wind with a speed of over 70 km/h.
  • Red: Gusts of wind with a speed of over 115 km/h.

Precipitation

There are 3 stages for precipitation risk, represented on the maps in different colours. The symbols indicate the predicted intensity of the precipitation.

  • Yellow surface: Greater than 50 mm within the preceding 24 hours.
  • Orange surface: Greater than 70 mm within the preceding 24 hours.
  • Red surface: Greater than 90 mm within the preceding 24 hours.
