Maidir le Rabhaidh Aimsire an Met Office

Tugann an Met Office rabhaidh don phobal agus do fhreagróirí éigeandála faoi dhálaí aimsire diana nó contúirteacha a bhféadfadh beatha daoine a bheith i mbaol nó cur isteach forleathan a bheith mar thoradh orthu tríd an tSeirbhís Náisiúnta Rabhaidh Dálaí Aimsire Diana (NSWWS).

Eisíonn an Met Office rabhaidh faoi fhearthainn, sneachta, gaoth, ceo agus leac oighir. Tugtar dathanna ar na rabhaidh seo ag brath ar mheascán den dóchúlacht go dtarlóidh siad agus an tionchar a d'fhéadfadh a bheith ag na dálaí.

Tá tuilleadh eolais ar Met Office Weather Warnings Guide.

Lively week of weather at home and away

Our weather had a distinctly autumnal feel this past week, in stark contrast to the same week last year. We had our warmest day of 2016 on the 13th of September when Gravesend in Kent reached 34.4 Celsius. On the same day this year we struggled to reach 19.6 Celsius at Manston in Kent with the rest of the country much cooler.

We also saw our first named storm of the season on Tuesday when Storm Aileen brought severe gales across the central swathe of the British Isles.
We cannot talk about named storms over past week without a mention of Hurricane Irma.

Irma was the second strongest ever Atlantic hurricane with sustained winds of 185mph and gusts of over 200mph. For three days it was at the highest hurricane level, category five; the longest period of time for any Atlantic hurricane. It followed Hurricane Harvey as being the first year we have seen two category four hurricanes make landfall in continental USA since hurricanes were first recorded back in 1851.

And now back to a much quieter period of weather coming up for the British Isles.

Weather starting to settle down

We will see the first signs of something more settled during the first half of this week. A ridge of high pressure will continue to edge in from the west during Monday and Tuesday and bring a lot of dry and bright weather with sunny spells. There will still be some showers running down the east coast of Scotland and England with scattered showers developing inland on Monday and Tuesday afternoons. Still quite cold at nights too and daytime temperatures also a little below normal.

Towards the middle part of the week, we lose the cold northerly winds and instead begin to pick up a milder southwesterly breeze. This will be one of the main changes during the week as night times become much milder and temperature during the days also a few degrees higher.

The drier, warmer weather will continue in the east on Wednesday and into Thursday but western areas will see some wet and windy weather. The rain will edge eastwards to many places later on Thursday. Over next weekend, south and eastern areas will be mostly dry with sunny spells. Northwestern areas will be cloudier and breezy for time with a little rain.

September to end on a high

The last week of September is looking more promising with the possibility of high pressure dominating our weather. There is still some uncertainty due to active storms in the tropical Atlantic and the remnants of some of them will move northwards into the mid latitudes. This can quite often have a beneficial effect on our weather by helping to reinforce high pressure close to the British Isles. So the weather looks set to be mostly dry with some sunshine but perhaps occasional rain and stronger winds at times towards the northwest. However, high pressure at this time of year does bring its own set of problems. The combination of clear skies and light winds will lead to quite cold nights. Also there is likely to be some overnight mist and fog patches. As the strength of the sun becomes less, it will take longer after sunrise for the fog patches to disperse and some areas could well see some fog lingering till the middle part of the morning. However, as daytime temperatures will be on the warm side and with light winds, ingredients are there for some fine late September days.

How long will the settled weather last?

As we move into October and the second month of the meteorological autumn, we look set to start off on a fairly settled note. At this stage, high pressure is still expected to be close to the British Isles maintaining a lot of dry and quite warm weather. There are indications that weather fronts bringing rain and strengthening winds will begin to edge into more north and western parts of the British Isles, with the driest, brightest and warmest weather becoming confined to more southern and eastern areas.

An tseachtain seo chugainn

Will the second half of October turn cold and wintry or wet and windy?

Réamhaisnéisiú míosúil
Ní furasta an aimsir a thuar níos faide ná seachtain nó mar sin chun tosaigh, fiú don réamhaisnéiseoir is mó taithí. Déantar samhaltáin uimhriúla casta a fháil ón Oifig Meitéareolaíochta agus ón Lárionad Eorpach do Réamhaisnéisí Aimsire Meánraoin (ECMWF) agus déantar iad a rith a lán uaireanta don mhí (agus don séasúr) atá le theacht. Ar an dóigh sin, cruthaítear pictiúr den dóchúlacht go rachadh cineálacha éagsúla aimsire i bhfeidhm ar an RA.
