WEATHER ALERT: Storm 'cyclone' to drag in wintry showers warns Met Éireann #sneactha #snow

Weather Advisory issued by the forecaster

Hot on the heels of Storm Arwen stormy weather is coming and this time Ireland looks set to be directly in the path of what Met Éireann terms 'cyclone' which will drag in polar weather and wintry showers.

Met Éireann has issued a Weather Advisory with warnings likely to follow for stormy conditions caused by weather driven across the Atlantic.

A commentary says this storm depression will develop in the mid-Atlantic on Monday as a result of dynamic forcing from jet streaks in the upper atmosphere. Forecasters say the depression will rapidly deepen upon its approach to Ireland as it tracks northeastwards over the Atlantic.

Meteorologists Emer Flood & Paul Downes said the associated wind field will reach Ireland from Monday night. 

"The exact track and timing of the cyclone is not definite at this stage as there have been small differences between successive model runs. Therefore, the location and timing of the strongest gusts is not certain yet, but Atlantic coastal counties will likely experience the strongest winds during Tuesday.

"The depression will likely move slowly eastwards over or near Ireland overnight Tuesday and during Wednesday as it starts to fill and weaken. It will likely track eastwards away from Ireland overnight Wednesday pull in a cold polar airmass in its wake.

The forecasters also outlined the possible impacts.

"This cyclone will bring gales across much of Ireland during Tuesday, with damaging gusts likely in some areas, and gales or strong gales developing in most sea areas, with storm force winds possible for a time at times on Tuesday.

"The strengthening winds will be accompanied by a spell of heavy rain on Tuesday, followed by heavy showers. Showers will continue overnight Tuesday and through Wednesday. With colder air wrapping around the depression centre and pulled over Ireland on Wednesday, there is potential for some of the showers to fall as sleet, or snow on high ground.

"We are currently entering a period of Spring tides with the peak expected on Monday; however coastal levels are expected to remain normal over the weekend and into Monday due to low surge levels forecast. Coastal levels are expect to be elevated later on Monday night and Tuesday as a deep low pressure system approaches from the Atlantic and due to the coincidence of high spring tides, strong and gusty winds, and expected large surge levels.

"There is still uncertainty between model runs on the timing and path of the low pressure system, which should improve as future model runs become available," said the weather experts.

The Met Office, Met Éireann's storm forecasting partner, has also said the weather patterns in the Atlantic show the potential to generate 'really powerful' conditions. 

Storm Barra would be the name of the next Atlantic storm. The Met Office correctly forecast Storm Arwen which caused a lot of damage in Britain and Europe.

The weather on its way caused Met Éireann to issue a Weather Advisory on Friday, November 3. It also says there is also the potential for "wintry precipitation" on Tuesday night and Wednesday which may lead to further travel disruptions.

Met Éireann said this advisory will be updated on Saturday while warnings will likely be issued on Sunday. More BELOW tweet.

Met Éireann's weather overview for the weekend is dry but cold weather. It says the weather will turn unsettled again early next week, with a spell of windy and showery weather developing on Monday night and Tuesday. MORE BELOW TWEET.
