  to continue in future. The amount of sea ice in the Arctic and Antarctic can be measured using sea ice ‘extent' - the total area of ocean for which at least 15% of the surface in the immediate vicinity is ice-covered. Sea ice extent is not constant throughout the year; sea ice grows and melts in response

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
