   # Group Warning
   
   ## Retrieve severe weather warnings [/warnings?location={latitudeInDegree,longitudeInDegree}]
  
positive.code: ### Forecasted weather for a given *latitude* and *longitude* [GET]
  
  + Parameters
      + locatedAt: `48.2047,11.4513` (string, required) - longitude,latitude; can occur multiple times for multiple locations
      + fields: `dewPointTemperatureInCelsius,maxAirTemperatureInFahrenheit,relativeGlobalRadiationInPercent,evaporationMakkinkInMillimeter,visibilityProbabilityLessThan200MeterInPercent,weatherCode,locatedAt,saturationDeficitInHectoPascal,precipitationProbabilityMoreThan4_4MillimeterInPercent,validFrom` (string, required) - comma separated list of parameters to be contained inside response 
      + validFrom: `2016-11-24T11:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
      + validUntil: `2016-11-29T11:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
      + validPeriod: `PT0S,PT1H,PT3H,PT12H,PT24H` (string, required) - comma separated list of periods to be retrieved. use iso8601 time duration notation. PT1H refers one hour forecast periods.
  
  + Response 200 (application/json)
  
  
negative.code: 
  + Parameters
      + locatedAt: `qx4x68in6Bmpug19Ew902zmk2C` (string, optional) - compressed list of station locations, using Microsoft Point Compression Algorithm, is efficient for up to 400 locations  
      + fields: `dewPointTemperatureInCelsius,maxAirTemperatureInFahrenheit,relativeGlobalRadiationInPercent,evaporationMakkinkInMillimeter,visibilityProbabilityLessThan200MeterInPercent,weatherCode,locatedAt,saturationDeficitInHectoPascal,precipitationProbabilityMoreThan4_4MillimeterInPercent,validFrom` (string, required) - comma separated list of parameters to be contained inside response 
      + validFrom: `2015-11-24T11:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
      + validUntil: `2015-11-24T12:00:00Z` (string, optional) - ISO8601 timestamp notation, means incl. this timestamp; always provide a time offset, e.g. 'Z' for UTC; optional: a request may provide correct offset (so that server can convert to UTC).
      + validPeriod: `PT0S` (string, required) - comma separated list of periods to be retrieved. use iso8601 time duration notation. PT1H refers one hour forecast periods.
