Met Office yellow fog warning for Friday morning, with possible travel disruption

The Met Office has issued a yellow weather warning for fog, in force on Friday 30 October 2026. The warning was issued at 04:18 UTC and runs until 10:00 UTC.

What the warning covers

According to the Met Office, fog, dense in places, may cause some travel disruption to begin with. The most extensive and disruptive fog is expected during the morning rush hour, when many people are travelling to work.

The forecaster rates the likelihood as very high (above 75%) and the impact as moderate. That combination is what makes the warning yellow.

In the version of the warning page we could access, the areas listed were in the East Midlands: Leicester and Leicestershire, Lincolnshire, Northamptonshire, Nottinghamshire and Rutland. The full list of areas may be longer, so it is worth checking the current Met Office warnings map.

What happens next

The Met Office forecast says the fog will slowly lift on Friday, followed by some sunshine. On Saturday 31 October, fog may linger in parts of England and Wales, although some sunny spells are expected. The Met Office says a more settled weekend is on the way as high pressure becomes increasingly dominant across the UK. No warnings are in force for Saturday and the days that follow.

What this means for you

People travelling to work or school on Friday morning should expect slower traffic and possible delays. The Met Office reminds drivers to know how to switch on their fog lights and to check that they work before setting off. Buses, trains, flights and ferries may also be affected, so it is worth checking for updates from your travel company before you set out.
