Walkers in Snowdonia are set to receive tweets to keep them up-to-date with weather conditions.
Hikers heading for the mountains in their winter jackets
will learn if they need waterproofs
or sun cream as the national park authority has launched an update surface that those with smartphones can access.
Regular updates are available under the twitter names @safesnowdonia in English and @eryridiogel in Welsh.
Llanberis Mountain Rescue team is backing the service, noting that it regularly helps out walkers who have gone up the hills without checking the weather forecast.
National park warden Gruff Owen who runs the service said it also helps if people know how to use equipment like crampons
and ice axes in winter.
He commented: "The mountains of Snowdonia are there to be enjoyed, but you will not enjoy the experience if you haven't prepared yourself adequately."
Other enhancements aimed at helping walkers in the hills at this time of year include earlier daily updates by the Mountain Weather Information Service.
This winter has seen it updating its morning forecast at 13:30 GMT, six hours earlier than previously.
