Drivers are being warned to expect difficult travelling conditions as fog is forecast to develop across parts of North Wales from this evening.
The Met Office has issued a yellow weather warning covering Conwy, Denbighshire, Flintshire and Wrexham, as well as Powys, from 6pm on Monday, 9 November, until 10am tomorrow.
Forecasters say fog is expected to redevelop during the evening and become dense in places overnight, with visibility potentially falling below 100 metres.
The warning means there could be slower journey times and disruption to transport services, including possible delays to buses and trains.
The wider Wales forecast also points to fog reforming overnight, with northern parts of the country expected to be particularly affected. Conditions are forecast to improve gradually during Tuesday morning.
The Met Office is advising motorists to check road conditions before setting out and allow extra time for journeys. Drivers should reduce their speed, use dipped headlights and leave a greater distance between vehicles. Fog lights should only be used when visibility is seriously reduced and switched off again when conditions improve.
Fog can be particularly difficult for drivers because it may be patchy, with visibility changing quickly over relatively short distances.
The yellow warning is classed as a moderate-impact alert, with the Met Office assessing the likelihood of the forecast conditions at between 50 and 75 per cent.
People planning journeys overnight or during Tuesday morning are being advised to keep up to date with the latest local forecast and travel information.
