A thick blanket of haar descended on the Capital this morning and as the sun rose, the scale of the foggy substance could be seen across the city.
These pictures show just how thick the harr was heading out to the east coast.
When mild and moist air sits over chilly waters, you often get low cloud, mist, fog and drizzle.
The haar is then blown inland by the wind.
What is haar?
Typically it forms in spring and summer over eastern Scotland and England
Variants of the term in Scots and northern English include har, hare, harl, harr and hoar.
