Met Éireann uses three categories of weather warnings: status yellow, status orange and status red.

Status Yellow

Weather alert | Be aware

Met Éireann says a status yellow weather alert is issued "to notify those who are at risk because of their location and/or activity, and to allow them to take preventative action.

"It is implicit that 'yellow' level weather alerts are for weather conditions that do not pose an immediate threat to the general population, but only to those exposed to risk by nature of their location and/or activity."

Status Orange

Weather warning | Be prepared

Met Éireann says the "orange" category is "for weather conditions which have the capacity to impact significantly on people in the affected areas".

It says the issuing of an "orange" level weather warning implies that all recipients in the affected areas should prepare themselves in an appropriate way for the anticipated conditions.

Status Red

Severe weather warning | Take action

This is the highest level of warning.

Met Éireann says the issuing of "red" level warnings implies that "recipients take action to protect themselves and/or their properties; this could be by moving their families out of the danger zone temporarily; by staying indoors; or by other specific actions aimed at mitigating the effects of the weather conditions".
