About this section

How we keep it honest.

This page keeps ordinary inconvenience separate from life-safety alerts. Official notices retain their wording and source, each stream shows its own freshness, and “unavailable” is never presented as “all clear.” Everything here is subscribable: the combined feed at /alerts.xml carries every category, and each category — weather, marine, power, earthquakes, tropical — has its own feed with full details per entry.
