Storm Erik brings 'weather bomb' conditions
by BBC News NI Weather Presenter Cecilia Daly
Erik is the sixth named storm this season, after Ali, Bronagh, Callum, Diana and Deirdre
Storm Erik will approach Ireland and the UK bringing severe and damaging gusts.
The low pressure area was deepening rapidly as it approached the north west of Ireland and north-west Scotland on Friday morning.
This is known as rapid cyclogenesis, or explosive cyclogenesis, because the centre of the low pressure drops quickly over a short period of time and therefore the storm intensifies rapidly.
This is also sometimes known as a weather bomb.
Peak gusts across Northern Ireland will be 60 to 70mph but could be close to 80mph towards the west coast of Ireland and this is why Met Éireann issued an orange warning for Counties Galway, Mayo and Donegal.
