Storm Bram to bring impacts to parts of the UK and Ireland on Tuesday
Storm Bram will bring a burst of powerful winds and heavy rain to parts of the UK and Ireland on Tuesday, with mild, wet and windy weather continuing into the middle of this week in the system’s wake.
This week’s unsettled and mild weather theme is all thanks to a strong jet stream above the North Atlantic Ocean. This strong jet stream will cause a rapidly developing area of low pressure to move northwards to the west of Ireland and Scotland on Tuesday.
This low pressure system has been named Storm Bram by the Irish Meteorological service, Met Éireann, and will bring wet and windy weather to large parts of the UK and Ireland. The stormiest conditions will be across western Ireland, western Northern Ireland, and portions of Scotland. Indeed, the strongest winds will affect the Western Isles and western parts of the mainland of Scotland on Tuesday evening and night.

The UK Met Office has issued an Amber warning for strong winds for western Scotland and part of Northern Ireland for late Tuesday afternoon and Tuesday evening. Winds will gust to 70 or 80 mph for several hours on Tuesday evening, locally up to 90 mph for a time, as the tail of the storm passes by. This may lead to power outages, as well as travel disruption.
Tides are still high after the recent full Moon, and there will be a high tide on Tuesday evening. The strong winds will likely cause a higher tide than normal, and large waves will add to the risk of overtopping in coastal areas. Of particular concern will be the causeways which link some of the islands of the Western Isles, which are likely to be flooded during the peak of the tide and storm.
Storm Bram will soon move away from Wednesday, but further unsettled weather is expected through the rest of the week and into the weekend.

The strong jet stream over the North Atlantic Ocean will also cause Europe-bound flights from North America to get an added boost, shortening journey times but adding a few lumps and bumps along the way.
