Three adults phoned 999 and reported themselves in difficulty in the Scafell area, reporting sleet and strong winds and being very cold. Wasdale MRT attempted to locate them from around 3:30pm, but could find them, or re-contact them. When there was still no trace of them by 8pm the attempts to locate them was widened. Car parks in valleys in Borrowdale, Eskdale and Langdale were checked for a vehicle reported as belonging to them. During this time they were located by police heading back to Lincolnshire, seemingly not thinking it important to respond to the voicemail or text message attempts to contact them, or notify the police that they were safe... hey ho
The weather can change unexpectedly and you should be prepared for this. If you are immobilised because you or companion are injured, or because you become cragfast or benighted you will cool down very rapidly. A bivvi bag is useful (essential) to protect you in these circumstances.
