Boat of Garten, Scotland, United Kingdom Severe Weather Alertstar_ratehome

Information on update: The likelihood of impacts has been increased, particularly for Orkney, and the end time brought forward. A rapidly deepening area of low pressure, Storm Dave, will cross Scotland on Saturday night before clearing into the North Sea on Sunday. Whilst some uncertainty remains in the exact track and shape of Storm Dave, a spell of strong southwesterly winds is expected to quickly develop during the early hours of Sunday morning. Gusts 60-70 mph are expected fairly widely with a small chance of gusts of 75-85 mph across Orkney briefly. Large waves may lead to some dangerous conditions around windward coasts.

This warning was originally issued as a dual warning for Rain and Snow. Information on update: The warning is now a combined rain and snow warning to cater for possible impacts at lower elevations from heavy rain. The impact level has been lowered with the area reduced to northwest of Great Glen. Rain arriving from the south through Saturday afternoon is likely to turn to sleet and snow over hills as it meets cold air across central and northwest Scotland.

During the evening, snow may turn heavier and, as winds increase, blizzard conditions with drifting and blowing snow are likely to lead to very poor visibility across the hills and mountains of northwest Scotland.

Accumulating snow on roads will mostly be above 200 m elevation, where 5-10 cm is possible and a small chance of 10-20 cm.

Meanwhile at lower elevations, particularly across the Western Isles and Skye, persistent and heavy rain may lead to some impacts from surface water flooding. Following rain on Thursday night, a further 20-30 mm of rain is expected widely with 40-50 mm in places. Most of this will fall in around 6 hours.
