What's happened
The Met Office has warned of dense fog with visibility potentially dropping to 50 metres or less, disrupting travel across much of England, Wales and parts of Scotland. The fog is expected to clear gradually on Monday, but patches could linger into the afternoon. Drivers, commuters and travelers are urged to allow extra time and check updates from operators.
What's behind the headline?
Analysis
- Dense fog is a predictable seasonal risk that is now affecting multiple transport modes, including road, rail and air.
- The convergence of long nights and light winds is driving a rapid temperature drop, which increases frost risk and reduces visibility.
- This update will force operators to adjust schedules and could create knock-on delays in travel and logistics.
- Readers should plan ahead for potential disruptions and monitor operator advisories for real-time changes.
How we got here
A cold snap and clear nights have created the perfect conditions for dense fog. Long nights, clear skies and light winds have contributed to widespread fog formation across the UK, with the southwest already experiencing drought relief from slow-moving rainfall forecast later in the week.
