Met Office Chief Forecaster Neil Armstrong said: “Storm Amy will be an impactful autumn storm for many in Scotland and Northern Ireland, though impacts will also spread to northwest England and Wales, as well as a more widespread windy period for the rest of the UK.

“Within the Amber warning areas, damaging gusts of around 100 mph are possible for a time on Friday evening for parts of western Scotland, especially Skye, Tiree, Barra and western Lochaber. This could lead to significant disruption, and brings the risk of power cuts and damage to buildings and trees. Elsewhere, gusts of 60-80 mph are expected more widely in the Amber warning areas, and slightly lower figures for those covered by Yellow warnings.

“Rainfall is an additional hazard, in particular over western Scotland, where totals could exceed 30-50mm in 6-9 hours, increasing the risk of flooding for some. A number of warnings have been issued covering the rainfall risk for the coming days.”
