It says the area – which includes Aberdeen and most of Aberdeenshire, as well as parts of eastern Moray – will receive persistent heavy rain for most of the day.

This may result in some local flooding and travel disruption, as rainwater collects on roads and train services are impacted.
A small patch of the southern Highlands will also be covered by Friday’s thunderstorm warning, which affects most of mainland Great Britain between Fort William and Nottingham and will last from 4am until a minute before midnight.
On Saturday, that thunderstorm warning will stretch to include the entirety of mainland Scotland, as well as most of the Inner Hebrides.
This warning will also come into effect at 4am and last until a minute before midnight.
The Met Office website forecasts: “Heavy, slow-moving showers, some thundery, may cause travel disruption and flooding in a few places.”
Flooding and lightning strikes may cause delays and some cancellations to train and bus services, while the same conditions may cause damage to homes and businesses.
