Southeastern has said some of its services could have to go slower while lines are checked for fallen trees.

Speed restrictions are in place on some routes due to the adverse weather.

Drivers across the region are being urged to check weather and driving conditions before setting out on journeys and pay particular attention to exposed locations such as coastal and high lying areas and bridges which could be affected by the high winds.

Gary Webb from Highways England said: “We are working closely with the Met Office to monitor weather conditions and would encourage drivers, especially those driving high sided vehicles, motorcycles or considering a trip with a caravan, to consider driving conditions before setting off as they could be difficult.

“If you do have to make a journey by road be prepared, plan your journey in advance and check the latest weather conditions along your route.

“Be aware of sudden gusts of wind, and give high-sided vehicles, caravans, and motorbikes plenty of space. In the event of persistent high winds we may need to close bridges to traffic for a period, so please be alert for warnings of closures and follow signed diversion routes.”

Road users are being advised to follow messages on the overhead signs and listen to radio updates. Further information can be found by visiting Highways England or calling its Information Line on 0300 123 5000.
