Forecast For Abersoch Issued: Wednesday 19th September, 2018 at 8.05am By Chas

   

 

Headline Summary: Severe Gales.

General Situation: Good morning - bore da... After the gales from ex-hurricane Helene, the winds are expected to become stronger today due to a Met Office named storm - storm Ali. Gusts over 50mph from the south / south-southwest have already been recorded on the peninsula today and theese could increase to between 60mph and 70mph during the morning, perhaps exceeding 70mph. There is nothing particularly unsual about this, but such high wind speeds do bring some issues if they occur during the daytime. Looking ahead, and after some less windy but rather wet weather on Thursday, the gales return for Thursday night Friday, before a potentially decent spell on Saturday morning. Eyes then turn to Saturday night / Sunday when a really rather unpleasant looking storm system is set to bring another spell of severe gales, with the track of this low looking a bit further south, which could bring some disruptive winds to Wales and England...

Today (Wednesday): Cloudy this morning with south-southwesterly to southwesterly severe gales with winds gusting potentially between 60mph and 70mph for a time, possibly a touch higher. The cloud is expected to bring some showery outbreaks of drizzle or rain. Brighter and drier this afternoon and evening with winds gradually easing down in relative terms, though remaining gale force. Mild temperatures, despite the winds. Rain arriving late evening.

Tonight: Winds easing further but persistent rain overnight, possibly heavy.

Thursday: A wet day with cloud and rain or drizzle, perhaps lasting through much of the day! Winds may become light and variable for a time before winds pick uo from a southerly quarter later in the day, when gales are possible, veering to the west or northwest during the evening, when some brighter weather may arrive for a time. Chance of some heavy rain late in the day, perhaps with some thunder, as a front passes through, along with some squally winds.

Friday: Strong to gale force west to west-northwesterly winds on Friday, bringing a mixed bag of conditions with one or two showery spells possible, along with brighter and drier spells, when there should be some sunshine. Feeling fresher.

Outlook: OK on Saturday morning, cool, with light to moderate winds from a westerly quarter, with some bright weather at times, with variable amounts of cloud. Cloud may increase later in the afternoon, with some evening and overnight rain. Winds may become gale force overnight from the southeast or south, depending on the track of a nasty looking low that could bring severe gales later in the night and into Sunday. Stormy winds a possibility on Sunday with squally showers and some sunny periods too. Note that the wind strengths on Sunday could be disruptive. Bright and breezy on Monday with some pleasant spells of sunshine, with the shower risk generally fairly low.

Extended Outlook: The outlook this morning for the period from 25th September 2018 to 29th September 2018 - remains up in the air this morning, however, there does continue to be hints of high pressure perhaps bcoming more influential at times, perhaps bringing a couple of days of decent weather, in a generally changeable outlook.
