Global baseline comes first
Every supported country keeps the global weather, earthquakes, disaster discovery, public dates, civic dates, Country Now, sports and structured-event baseline. Country packs are additions, not replacements.
Canada, England and New Zealand add official depth
Canada can add ECCC weather alerts and AQHI observations; England can add Environment Agency flood warnings; New Zealand can add GeoNet earthquake and volcano context. These layers are only queried for matching selections.
The United States gets river context too
NOAA National Water Prediction Service gauge status joins the existing U.S. warning, wildfire, tropical, severe-storm, volcano, tide and FEMA layers. Routine gauges stay hidden unless a meaningful flood category is present.
