Freezing fog is expected to develop across parts of southeast England on Thursday night before clearing on Friday morning. Visibility could fall below 100 metres in places. Additionally, following rainfall during Thursday daytime, a few patches of ice could form on untreated surfaces. What Should I Do? Give yourself the best chance of avoiding delays by checking road conditions if driving, leaving extra journey time, or amending plans if necessary. Make sure you know how to switch on your fog lights, and check they are working before setting off on your journey. Bus and train services, as well as flights may also be affected; check for updates from your travel company and follow their advice. Be prepared for weather warnings to change: when a weather warning is issued, the Met Office recommends staying up to date with the weather forecast in your area.
