Planning Outlook

Very wet across many mountains this week. Worst conditions focused on the Lakes and Wales by Wednesday-Thursday, where a slow-moving front brings prolonged heavy rainfall and a likelihood of flooding. Staying unsettled through into the weekend, often windy, periods of gale or severe gales continuing on the mountains. Above freezing through midweek, then becoming cooler. By the weekend into next week, colder conditions are expected to prevail, with higher Munros sub-zero for a run of days into the start of November. A marked lowering of freezing level is likely for a few days next week with showers of snow and hail on the hills at times.
