A yellow weather warning has been issued for most of Scotland - including parts of West Lothian - starting at 8am Friday morning and lasting until 2pm in the afternoon.
The UK Met Office has warned of heavy rains bringing a chance of flooding and disruption and likely traffic, train and bus delays across the country.
The weather forecasters said bus and train services will “probably be affected with journey times taking longer,” and warned that “spray and flooding on roads will probably make journey times longer.”
