In Rhostryfan and, more broadly, across Gwynedd:
This morning, skies are mostly cloudy with cool temperatures ranging from 15 to 17 degrees Celsius. The wind is noticeable, coming from the southwest at around 22 mph, with gusts reaching up to 35 mph, which may cause some movement of loose objects. During the afternoon, the cloud cover will persist, and there is a high likelihood of rain, with an approximate accumulation of 3.4 mm. The wind is expected to remain gusty, possibly reaching similar speeds as in the morning. Conditions could feel quite breezy and damp throughout the day, so it's advisable to keep an umbrella handy if planning to be outdoors. Temperatures are unlikely to rise significantly, maintaining a cool and rather unsettled atmosphere.
