Fog warnings cause travel disruption across UK
The Met Office issued yellow fog warnings for much of England, Wales and Northern Ireland, leading to reduced visibility, road accidents and flight delays. Drivers are advised to allow extra time, use fog lights and adjust speed, while airlines warn passengers to check flight status.

Background
The Met Office explained that a large area of high pressure over the UK created ideal conditions for dense fog, with overnight temperatures dropping to 3‑5 °C and light winds allowing moisture to condense into fog with visibility under 100 m [1].
Warnings were issued for much of England, Wales and Northern Ireland, and transport operators such as Heathrow and Bristol Airport advised passengers to allow extra travel time and check flight status due to reduced visibility and flight diversions [1][2].
Questions people ask
Why is there so much fog this week?
Because low overnight temperatures, clear skies and light winds created a perfect recipe for fog, as stated by the Met Office [1].
Should I still travel if a fog warning is in place?
Drivers are advised to allow extra time, use fog lights, reduce speed and increase following distance, while passengers should check with airlines or transport providers for updates [1][3].
What caused the multi‑vehicle collisions on the M20 and A303?
The collisions occurred due to extremely low visibility from dense fog, which made it difficult for drivers to see other vehicles [1].
