If you’ve ever checked the weather and seen a “moderate snow ice warning” appear on your screen, you’re not alone. These alerts can be confusing—especially when Ireland is bracing for back-to-back storms in January 2026. This article explains exactly what a moderate snow and ice warning means, how it compares to other warning levels, and what’s happening with Storm Goretti and ex-hurricane Erin.

What does moderate snow and ice warning mean?

A moderate snow and ice warning is a classification used by Met Éireann when snowfall of at least 3 cm is expected within 24 hours, combined with the risk of icy surfaces. It is not the highest alert—that is Red—but it still triggers preparedness actions from local authorities.

What is the strongest weather warning?

Met Éireann’s warning system has three tiers: Yellow (be aware), Orange (be prepared) and Red (take action). Red is the strongest level, reserved for extreme weather that poses a direct threat to life and property. During Storm Goretti, the UK Met Office issued a Red warning for Cornwall, while Ireland remained under Yellow (The Irish Times).

Why this matters

A Yellow warning means “be aware” – not “panic”. For most people in Ireland, a moderate snow/ice warning means slippery roads and possible school delays but rarely full closures. The 3 cm threshold is roughly the depth of a deck of cards, enough to make untreated paths hazardous.

Bottom line: A moderate snow/ice warning in Ireland means at least 3 cm of snow in 24 hours. It is a Yellow-level alert designed to prompt caution, not disruption. Red warnings are reserved for life-threatening events.

Where is Storm Goretti going to hit?

Storm Goretti tracked further south than initially forecast, so its heaviest impacts fell on southern England, not Ireland. Met Éireann meteorologist Ailís Hankinson said the storm “stayed further south than expected, reducing its impact on Ireland” (RTÉ).

How strong is Storm Goretti?

While the storm produced gusts of 99 mph (159 km/h) in Cornwall (The Irish Times), forecaster Linda Hughes described it as a “very strong storm” but said it was “too far to the southeast to cause major impacts in Ireland” (RTÉ). The storm’s overall effect on Ireland was described by Met Éireann as “not really very significant” (RTÉ).

The catch

Just one degree of latitude made the difference: if Goretti had tracked 100 km north, Ireland would have faced a more severe storm. That narrow margin underscores why local warnings matter more than UK forecasts.

Bottom line: Storm Goretti largely missed Ireland thanks to a southern track. Irish residents saw mainly rain, sleet and some hill snow – nothing like the red-warning conditions in Cornwall.

Is Storm Erin going to hit Ireland?

Ex-hurricane Erin is forecast to pass west of Ireland early in the week of 5–11 January 2026 (RTÉ). Because it has transitioned out of hurricane status, its winds are weaker, but it may still bring rain and blustery conditions to western coasts.

Is there another storm coming to Ireland?

Yes – the same weather pattern that pulled Goretti southeast could steer Erin’s remnants close to Ireland. However, at the time of writing, no official warnings have been issued for Erin (RTÉ). The situation is fluid, and Met Éireann advises checking forecasts regularly.

Bottom line: Ex-hurricane Erin is not expected to make landfall in Ireland but will bring rain and wind to western areas. It is no longer a hurricane and poses a much lower threat than Storm Goretti.

Is Ireland getting snow in 2026?

Snowfall is possible in Ireland during any winter, and January 2026 is no exception. A Status Yellow warning for snow and rain was already issued for four southern counties during Storm Goretti (VisaHQ). While no specific city snowfall totals are available, the moderate threshold of 3 cm in 24 hours has been met.

What is the snowiest city in Ireland?

According to general climate data from Wikipedia’s Climate of Ireland, the highest average snowfall occurs in inland and upland areas, not cities. However, the provided research notes do not define a “snowiest city” with official statistics.

Bottom line: Yes, Ireland can get snow in 2026 – the moderate warning proves that. But “moderate” means 3 cm, not blizzard conditions. The snowiest city in Ireland is not officially recorded in available sources.

Is moderate snow a lot of snow?

No – 3 cm over 24 hours is considered moderate because it causes slushy roads and possible ice patches but rarely brings life to a halt. By contrast, a Red warning would indicate snow depths that could cut off communities.

The key distinction is preparedness: under a moderate warning you can still drive (with care) and schools usually stay open. The real danger is hidden ice, not the snow itself.

Bottom line: 3 cm of snow in a day is not a lot by international standards. For Ireland, it’s enough to slow things down – but not stop them. Treat it as a nudge to drive slower, not to stay home.

Timeline: Storm Goretti and ex-hurricane Erin

  • 7 Jan 2026: Met Éireann issues Status Yellow snow/rain warning for Cork, Kerry, Waterford and Wexford (VisaHQ)
  • 8 Jan 2026 (12:00–20:00): Warning active – rain, sleet and hill snow; winds on south coast (RTÉ)
  • 8 Jan 2026 (after 20:00): Warning expires; cloudy with rain in Munster and south/east Leinster (RTÉ)
  • 9 Jan 2026: Icy conditions, scattered showers, hail and possible thunderstorms; highs 3–7°C (The Irish Times)
  • Weekend after 9 Jan: Milder conditions return (RTÉ)
  • Week of 5–11 Jan: Ex-hurricane Erin passes west of Ireland (RTÉ)
Bottom line: The threat window for Storm Goretti in Ireland was tight – just eight hours on 8 Jan. After that, the focus shifts to icy roads on 9 Jan and ex-hurricane Erin later in the week.

What’s clear and what’s not

Confirmed facts

  • Yellow snow/rain warning issued for Cork, Kerry, Waterford, Wexford on 7 Jan 2026 (VisaHQ)
  • Moderate snow/ice warning criteria: 3 cm snow in 24 hours (Met Éireann (national meteorological service))
  • Storm Goretti period: 8–9 Jan 2026 (RTÉ)
  • Ex-hurricane Erin to the west of Ireland on Monday (RTÉ)

What’s unclear

  • Exact path of Storm Goretti over Ireland (RTÉ)
  • Whether ex-hurricane Erin will make landfall (The Irish Times)
  • Snowfall amounts for specific cities (RTÉ)
  • Official criteria for Orange and Red snow/ice warnings in Ireland (no primary source provided)

“The storm stayed further south than expected, reducing its impact on Ireland.”

– Ailís Hankinson, Met Éireann meteorologist (RTÉ)

“It’s a very strong storm, but it’s too far to the southeast to cause major impacts in Ireland.”

– Linda Hughes, forecaster (RTÉ)

For Irish residents, the implication is clear: a moderate snow and ice warning means prepare for slippery surfaces and minor delays, not a lockdown. The real wildcard remains the track of Storm Goretti and the remnants of ex-hurricane Erin. Stay tuned to Met Éireann’s local updates – they’re your most reliable guide.

Frequently asked questions

Can moderate snow and ice warning cause travel disruption?

Yes – even 3 cm of snow can make untreated roads and footpaths icy, slow traffic and cause delays on bus and train services. The National Emergency Coordination Group advised activating winter-service plans and deploying gritters (VisaHQ).

How often does Ireland issue moderate snow warnings?

Met Éireann issues Yellow warnings for snow/ice whenever the 3 cm threshold is expected – typically a few times each winter, especially in inland and upland areas.

What is the difference between yellow and orange snow warnings?

Yellow is “be aware” – snow/ice likely but not extreme. Orange is “be prepared” – significant snow/ice that could disrupt travel and power. Both are below the Red level for life-threatening conditions.

How should I prepare for a moderate snow warning?

Check your car’s tyres and wipers, allow extra journey time, and keep an eye on local forecasts from Met Éireann. If you’re walking, take care on untreated pavements.

Are schools closed during a moderate snow warning in Ireland?

Usually not. School closures only happen under Orange or Red warnings, or when local conditions make roads unsafe – but each school makes its own decision.

How long do moderate snow warnings typically last?

Most are issued for 12–24 hours. The Goretti warning ran from 12:00 to 20:00 on 8 Jan 2026 – an eight-hour window (VisaHQ).

What is the difference between snow and ice warnings?

A snow warning focuses on snowfall accumulation (3 cm+). An ice warning highlights the risk of freezing rain or black ice even without snow. The two are often combined as “snow/ice” when both hazards are expected.
