The overview table shows forecast warnings for all locations within a country. It uses threshold values to warn of medium (yellow) and high (red) risks
Data and Warnings
The overview table shows 3 levels of risk for 4 parameters. A warning is issued if the value for one parameter exceeds the thresholds set.
For minimum temperature, a medium risk warning is shown, if the temperature forecast at the specified location drops below 5°C once during the date. If the temperature forecast drops below 0°C, the high risk warning is shown.
For maximum temperature, medium or high risk warnings are shown, if the temperature forecast at the specified location exceeds 30°C or 35°C once during the date.
For precipitation, medium or high risk warnings are shown if the amount of precipitation forecast at the specified location during the date exceeds 5 or 15 mm of water. This warning is applied to both rain and snow equally. Snow amounts are converted into the equivalent amount of water, where 1 mm of water corresponds to approximately 10 mm of snow cover.
For wind speed, medium or high risk warnings are shown, if the maximum wind speed forecast at 10 meter above ground for the specified location exceeds 25 or 75 km/h during the entire date. The local wind speed is an indication of expected air movement, which may differ depending on topography, exposition or particular conditions.
For special service, the warnings thresholds can be selected by the customer to give a general indication of important risks, and are applied to all locations covered by the service.
