Drivers are being urged to take care this morning as strong winds and unsettled weather are affecting many areas of Wales. The Met Office has issued a yellow warning for wind from 20:00 on Sunday 14 September until 18:00 on Monday 15 September. Wind gusts are expected to reach 45-55 mph inland, and up to 60-70 mph in exposed coastal and hilly zones.
Rush-hour traffic is likely to be especially difficult: bridges and exposed routes are under strain, and several closures and restrictions are already in force. If you’re travelling this morning, especially on major trunk roads or over bridges, allow extra time, check conditions, and avoid high-sided or vulnerable vehicles where advised.
