Word for "someone who warns"

Question

I'm trying to write out an document of sorts though I need the word for "someone who warns". I've done a bit of searching but couldn't find anything.

I initially thought it was "warner" though it doesn't show up in the English dictionary and doesn't exactly sound right.

So I ask, what is the correct word if there even is one. If there isn't a correct word, what would be best to use as surely, "someone who warns" can't be?

1. One who admonishes; one who warns of faults, informs of
    duty, or gives advice and instruction by way of reproof or
    caution.

    school in the absence of the instructor, to notice the
    absence or faults of the scholars, or to instruct a

3. someone who gives a warning so that a mistake can be avoided

It has the same root as admonish but describes the person and their authority.

Not a very common term, but close to what you are looking for:

forewarner:

one that forewarns

to forewarn :

to warn (someone) before something happens

also: premonitor:

One who, or that which, gives premonition, a warning in advance; a forewarning.

(from M-W)

A harbinger is

a person who goes ahead and makes known the approach of another; herald.
anything that foreshadows a future event; omen; sign: Frost is a harbinger of winter.
a person sent in advance of troops, a royal train, etc., to provide or secure lodgings and other accommodations.

If your "warner" is able to warn, but is not believed, then a classical reference to being a Cassandra might be in order.

Gerger · Answer

Could you use watchdog? It focuses on the watching as opposed to the warning, so it might be a little off. If we're talking "watchdog agencies" though (my experience with the word), the warning is strongly implied.

Warner is a word and it appears in dictionaries. It sounds right to me. Warner Bros. makes it harder to search though.

One who warns or gives warning to others.
  
  [OED]

One who warns.
  
  [Wiktionary]

someone who gives a warning to others
  
  [TFD] and [Vocabulary.com]

An example from a news article:

Müller is a warner. He warns against running Europe into the ground "out of convenience," merely for the purpose of preserving the euro, which, according to Müller, is much too strong for the weak countries in the south but too weak for the strong German economy.

It usually appears in religious contexts though and prophets are considered as a warner:

In other words, a messenger and prophet is a warner but a warner isn’t necessarily a messenger or prophet.
  
  http://www.answering-islam.org/Quran/Contra/only_warner.html

Warner can be used for objects too, like a warning system:

The helicopter's electronic warfare systems include a radar warning receiver, laser warning receiver, missile approach warner and chaff and flare dispensers.

Giant Leap · Answer

Watchman
In ancient days, these were soldiers assigned to the towers that surrounded the city walls. They warn of people approaching, most often, raiding parties. Sometimes, they are sent out to ask if the arriving party comes in peace or not if someone travels alone. Their function also includes identifying people who come near the walls, and relay the message to another person (usually a runner/messenger) to ask permission from authorities for entry. Sometimes, they sound a trumpet to warn the citizens within the walls about imminent danger, or provide another signal of what lies outside the walls.

My suggestion is a Sentry.
Admonish has the connotation of scolding, telling off. If the usage is someone who is on the lookout, then Sentry is more appropriate in my view.
