Notice
Notice is the time between Met publishing a warning and the warning starting. It is recorded for every warning, and again whenever an area is added, the level is raised, or the start moves earlier.
There are not yet enough warnings to read any pattern from this.

How this works
- Every 10 minutes, the archive reads Met Éireann's warnings pages, its RSS feed and its open data on met.ie. Everything shown here comes from those sources.
- Each warning is kept as Met published it. When Met changes a warning, the change is added to its history. Nothing is overwritten.
- Times. The warnings pages give Met's Issued time and the original start, to the minute. The RSS feed gives the time of each change, to the second.
- Notice is the start time minus the time Met published it. Anything up to one minute counts as zero notice. That includes warnings published after they had already started, which are also counted separately as already started.
- Notes mark anything unusual, such as two met.ie sources that disagree. They are shown, never quietly resolved.
- Coverage. met.ie keeps no history, so the archive starts on the day collection began. A change that Met makes and undoes within 10 minutes may be missed.
