Pack: jma · Endpoint: https://gateway.pipeworx.io/jma/mcp

Current weather warnings and advisories (警報・注意報) for a Japanese region, from the Japan Meteorological Agency (JMA). Returns the headline bulletin plus per-area status (issued / continuing / lifted / no warnings in effect) for every warning/advisory category JMA tracks (heavy rain, storm, flood, wave, storm surge, dense fog, thunderstorm, avalanche, frost, etc.), at both the sub-prefecture and municipality level. Sourced from www.jma.go.jp/bosai/warning/data/warning/.json. Accepts a place name (English or Japanese) or a JMA office code, resolved the same way as jma_resolve_area. Category and status names are native Japanese with an English gloss from JMA’s fixed warning-code table.
