Not documented

  • no time of issue: a row does not say when the warning was issued or changed (the file's Last-Modified header is the nearest thing)
  • the time zone of startTime and endTime (the documentation says forecasts are in UTC; for warnings it says nothing)
  • the areas MCN, MRM (in the feed) are in no id table: distrits-islands.json has MCS and MPS only
  • no identifier for a warning: a changed warning is a different row, not an update of the same one
