Field notes
The homepage organizes coverage by country and offers state- and province-level browsing, alongside search. Its “vs normal” measure compares a reading with the middle of that gauge’s historical range for the same date; the site calls this a statistical guide, not advice. Flood listings use NOAA National Weather Service labels, including major and minor flooding.
