Age above which a warning feed counts as stale: 60 minutes. DWD republishes the feeds
every few minutes (on 2026-10-06 the nowcast feed was 4 minutes old, the Gemeinde and
coast feeds 10), so a feed an hour old means publishing has stopped or a mirror serves
an old copy, and warnings issued since are missing from it.
