How to say "advisory" in Japanese

• 注意報ちゅういほうCommon
  nounThe common word for an official advisory, especially a weather advisory issued by authorities to alert the public to hazards such as storms or flooding; this is the word you want for that sense.
• アドバイザリー
  no-adjectiveThe loanword, found mainly in business and financial contexts such as advisory services or advisory roles; being less common, it is not the word for a weather or public-safety advisory.
• 注意書ちゅういしょ
  nounA written caution or notice — text printed or posted to warn readers — so it matches 'advisory' only in that written-notice sense; for advisories in the announcement sense it is seldom the word you want.
