FOG could cause travel disruption this morning, the Met Office has warned.
A yellow weather warning has been issued for much of Hampshire, and will remain in force until 11am.
Parts of the of the A34 and A303 are expected to be affected, as well as the M4 to the west of Reading.
The Met Office says the fog could cause slower journey times with delays to buses and train services possible.
It also says there is a chance of delays and cancellations to flights.
A spokesperson for the Met Office said: "Freezing fog patches affecting some areas. Not everywhere will see fog, but there are some dense patches with visibility as less than 100 metres in some spots.
"Fog patches will be slow to clear and may last into the afternoon in a few places though visibilities should gradually improve during the morning."
