A storm is named by a National Met Service (Met Éireann, Met Office in the UK and KNMI in the Netherlands) when orange or red level wind speeds are forecast to impact over a wide land area. Orange or red level gust wind speeds can occur in exposed areas without the event being named. Ireland's Weather Warnings will be issued at www.met.ie/warnings/today and on the Met Éireann app.

Notes:

Sustained wind speeds refer to the average (10-minutes) land wind speeds.
Gust wind speeds refer to the average (3-seconds) wind speeds.
Rainfall refers to the rainfall total measured over 24 hours.
MSLP refers to the hourly mean sea level pressure.

The warning colour coding system is explained on https://www.met.ie/weather-warnings and the colours given in the image above indicates if land station observed orange, red levels winds or rainfall amounts. The table above provides details for each storm, including a link (on the storm name) to the named storm statement.

The colour levels given in the table are when the highest station observation for sustained and gust wind speeds, together with rainfall totals over 24 hours, are reached at a station, this is different than the criteria above which is that a warning issued for widespread wind speeds and this difference should be noted.

Yellow. Not unusual weather. Localised danger.
Widespread sustained wind speeds > 50 km/h
Widespread wind gusts speeds > 90 km/h
Rainfall* > 30 mm in 24 hours
Orange. Infrequent. Dangerous/disruptive.
Widespread sustained speeds > 65 km/h
Widespread gusts speeds > 110 km/h
Rainfall* > 50 mm in 24 hours
Red. Rare. Extremely dangerous/destructive. Widespread sustained speeds > 80 km/h
Widespread gusts speeds > 130 km/h
Rainfall* > 80 mm in 24 hours

* Amounts can be up to double on windward upper slopes and impacts vary depending on, for example, soil moisture deficits.
