During Storm Opheila in October 2017, the M5 Data Buoy recorded a wave off the south-east coast of Ireland measuring a height of 17.81 metres – that’s almost the height of a six-storey building!

#StormEowyn is now beginning to show the first ominous signs of cyclogenesis. The Airmass imagery shows a cloud head beginning to develop to the North of the wide baroclinic zone to the south of Newfoundland (highlighted below) This cloud head marks the 1st sign that a deepening low pressure is under cloud mask. The Low will cross through the Jet Core tonight and move into the highly divergent left exit region on Thurs Morning.
The 12Z Models have maintained the track and depth of the 00Z Run. The 12Z GFS Ensemble showing excellent agreement to support the earlier 06Z ECMWF Ensemble.
It must be reiterated again that #StormEowyn is likely to be one of the strongest storms to hit Ireland in many many years with wind gusts to 90-95mph even inland to the East of Galway Bay, and winds gusting to over 100mph along the coast, perhaps as high as 110mph along places like Mace Head.
Risk has increased for strong 90mph winds through the Central Belt of Scotland and winds to 100mph around the North Channel, Solway Firth. Winds also higher in parts of SW Scotland & extending slightly further north into the area north of Glasgow/Edinburgh.
Peak depth down to around 938mbs as the storm slams into the British Isles, likely to brush close to Belmullet Island.
Gusts in the Isle of Man and around the Irish Sea will be around 85-90mph, Inland gusts over Northern Ireland to 90mph.
I see nothing to downplay any aspects of this storm in tonight's guidance. I expect RED Danger to life warnings to be issued on Thursday Morning for parts of SW Scotland, Northern Ireland, Northern Irish Sea coasts.
#StormEowyn will be an extremely dangerous storm. We are very fortunate to have the NOAA Hurricane Hunters in Shannon where they will be flying NOAA42 KERMIT into #StormEowyn to gather extremely rare and extremely valuable research into this storm over the next couple of days. Currently in Shannon it will be flying research missions to help our understanding of such powerful cyclogenesis. I look forward to seeing their valuable research.
#StormEowyn is forecast to be an extremely powerful and violent storm across much of Ireland.
Widespread disruption and damage property and infrastructure is likely.
Please heed the warnings
