Status yellow wind warning for Donegal and Mayo as mixed week ahead

A status yellow wind warning covers Donegal and Mayo until 12:00p.m today (Tuesday, October 27), as Met Éireann forecasts a largely mixed week of rain, showers and breezy conditions punctuated by spells of dry weather.

The warning, in effect from midnight last night, flags very strong and gusty southwesterly winds early today. Residents in the two counties should expect displaced debris and loose objects, difficult travelling conditions, large coastal waves and some fallen trees and branches.

For farmers in the northwest, that means machinery moves, slurry spreading and any haulage on exposed roads carry real risk until midday. After that, the wind picture eases — but the showers do not.

What does Tuesday look like nationwide?

Cool and blustery, with widespread showers. Many will be heavy, and Met Éireann warns of isolated thunderstorms and possibly hail. Hail is the one to watch: it can shred remaining leaf on late crops and bruise stock out at grass.

Winds reach gale force along western and northwestern coasts this morning. Elsewhere, winds stay moderate to fresh from the west or southwest. Top temperatures sit at just 9°C to 12°C — cold enough to slow grass growth to a crawl.

Tonight, most areas start dry with clear spells as showers retreat to northern areas. But rain soon develops in the west and northwest and pushes eastwards overnight, lingering in the north until morning while clearing to isolated showers elsewhere. Lowest temperatures of 6°C to 11°C will occur early in the night, with moderate to fresh and gusty west to southwest winds, stronger towards Atlantic coasts.

Is there a spraying and harvesting window this week?

Wednesday (October 28) offers the best one. The morning starts mostly cloudy with outbreaks of rain in the north and well-scattered showers elsewhere, but from late morning onwards it turns largely dry with just isolated showers and some sunny spells.

Temperatures recover to 13°C to 15°C, with moderate to fresh southwesterly winds in the morning decreasing light to moderate and turning southerly later. Wednesday night stays dry apart from isolated light showers, partly cloudy, with lows of 9°C to 12°C on light to moderate southerly winds.

Thursday (October 29) is a different story. Mostly cloudy, with isolated patches of light rain or drizzle and the best of any sunny spells in the east and northeast. From the evening, more persistent rain or drizzle moves into the southwest and west as a moderate to fresh southerly wind develops, strong in coastal areas. Highs: 13°C or 14°C.

Thursday night stays cloudy and breezy as rain tracks eastwards across the country. Western areas turn drier and calmer overnight once the rain clears. Lows of 9°C to 13°C come with fresh to strong and gusty southerly winds, easing to light to moderate westerlies over the western half of the country by morning.

What about the weekend?

Friday (October 30) begins the improvement. Cloud and rain gradually clear from the east in the morning, leaving dry and bright conditions for most. More cloud pushes in from the south during the afternoon and evening, possibly bringing a few showers. Highs climb to 13°C to 16°C — the warmest of the week — with moderate to fresh southerly winds in the east at first, otherwise light and variable.

The bigger signal sits beyond that. Met Éireann has indicated higher pressure will build next weekend, possibly bringing drier and clearer weather. That's the window farmers should be planning for: if fieldwork can wait until then, the forecast currently argues for holding off.

The practical read on the week: take care in Donegal and Mayo before midday today, use Wednesday afternoon for anything weather-sensitive, expect rain to sweep east Thursday night, and watch Friday's clearing trend as the setup for a drier weekend.
