Status Orange rain warnings issued as Storm Austen tracks towards Ireland

Met Éireann has upgraded its Status Yellow warning for Storm Austen to Status Orange for rain, with the first alert covering Cork, Kerry and Waterford from 10:00pm on Thursday, October 22, until 5:00am on Friday, October 23. A second Status Orange rain warning for Dublin, Wexford and Wicklow runs from 2:00am until 8:00am on Friday.

Storm Austen is the first named storm of the season. Met Éireann has forecast intense rain associated with the system which, the forecaster warns, could have serious impacts. For farmers in the affected counties, that timing matters: the worst of the rain arrives overnight and in the early hours, precisely when intervention options are limited and livestock, fodder and machinery are most exposed.

What does an Orange warning mean?

Met Éireann operates a three-tier colour-coded alert system. Status Yellow is the lowest level, advising the public to be aware of potential impacts. Status Orange sits above it, signalling weather that could have serious impacts on people and property. It is the level at which transport disruption and flooding become genuinely likely rather than merely possible.

For the Orange counties, Met Éireann has set out three principal risks:

• Disruption and delays to public transport, both rail and bus;
• Flooding;
• Very difficult travelling conditions.

Those travelling to co-ops, marts or veterinary appointments on Friday morning in Dublin, Wexford and Wicklow should expect the tail end of the warning period to coincide with the start of the working day. The alert expires at 8:00am, but surface water and localised flooding may persist beyond it.

Where do the wider warnings apply?

Alongside the two Orange alerts, a Status Yellow rain and wind warning covers all of Ireland from 7:00pm on Thursday until 10:00am on Friday. Heavy rain associated with Storm Austen will spread eastwards across the country, while strong easterly winds will back north-westerly and strengthen further, especially in the south and south-east.

The Yellow-level impacts Met Éireann lists are:

• Difficult travelling conditions;
• Localised flooding possible;
• Outdoor events impacted;
• Debris and loose objects displaced;
• Some fallen trees and branches.

That combination of saturated ground and strengthening wind is the practical concern for landowners. Windthrown branches and displaced debris can block farm roadways and laneways, while localised flooding threatens low-lying fields, yards and any stores sited near watercourses.

How will the weather develop?

Very heavy rain will develop in the southwest on Thursday afternoon and extend north-eastwards through the evening. Localised flooding is possible, especially in Munster and Leinster. Light to moderate east to north-east winds will strengthen later in the day.

Thursday will be very wet and windy across southern counties, with highest temperatures of 10°C to 14°C. Thursday night will be very wet and windy, and stormy in the southeast. Widespread, heavy and persistent rain will affect much of the country, with some flooding expected across southern and eastern counties. Isolated thunderstorms will occur.

Overnight, cyclonic variable winds will veer north-west and strengthen further, reaching gale force in places. Lowest temperatures will range from 5°C to 8°C. Gale-force winds on top of persistent rain raise the risk of damage to sheds, sheeted stacks and any loose materials stored in the open.

What happens on Friday?

Lingering wet and windy weather will clear eastern counties by around mid-morning. Sunshine and well-scattered blustery showers will follow for the rest of the day, mainly affecting western counties. Highest temperatures of 9°C to 13°C are forecast. Fresh and gusty north-west winds will moderate before evening.

That means Friday afternoon should offer the first real window for checking stock, clearing debris and assessing any flood damage. Ground conditions will remain difficult well beyond the warning periods, and farmers in Munster and Leinster should watch Met Éireann updates as Storm Austen tracks across the country.
