Freezing fog will blanket Britain tomorrow, causing sparking transport chaos on the roads and in the air, forecasters warn New yellow weather warnings for freezing fog from 4am to 11am have been issued and it’s feared the dense fog will cause mayhem – especially at rush hour “Some dense fog and freezing fog patches on Tuesday morning likely leading to some travel disruption,” the Met Office spokesman said People are being told to expect “slower journey times with delays to bus and train services possible ” Meanwhile “there is a chance of delays or cancellations to flights.” The worst-affected areas include most of the Midlands, Home Counties and southeast of England Temperatures in these regions will struggle to exceed 5C. The Met Office warns: “Travelling in fog can be extremely dangerous Fog can drift rapidly and is often patchy.” Advice for road users when travelling in fog Avoid travel if possible Drive very slowly with dipped headlights, full-beam lights reflect off the fog causing a ‘white wall’ effect Keep an eye on your speed, fog can give the illusion of moving in slow motion Use fog lights, but remember to turn them off when the visibility improves Don’t hang on the tail lights of the car in front, rear lights can give a false sense of security Watch out for freezing fog which is made of water droplets that freeze on contact with objects such as the pavement, road, car, etc It can quickly form a layer of ice.
