An amber weather for extreme heat has been extended to cover the whole of Edinburgh, according to the Met Office.
Previously, the rare warning was only issued to parts of Midlothian and the Borders, but on Sunday, July 17, forecasters updated the warning to spread across the capital and most of Scotland, including East and West Lothian.
The Met Office say: "A hot spell is likely to develop from Sunday (July 17), likely peaking early next week, leading to widespread impacts on people and infrastructure."

Temperatures are expected to climb as high as 28c in Edinburgh on Monday and Tuesday, with the Met Office warning locals to expect "adverse health effects for those vulnerable to extreme heat," as well as noting that the wider population are likely to experience some adverse health effects including dehydration, nausea and fatigue.
The news comes just days after SEPA warned that the Firth of Forth was at 'moderate' risk of water scarcity due to the continuous dry weather in Edinburgh and the Lothians.
They said that the situation is being monitored, but advised businesses in the area to limit their water use and for locals to do the same while the rare conditions continued.
For Monday, July 18, the Met Office say: "Any morning low cloud around western coasts clearing to a fine day with very warm or hot sunshine and mainly light or moderate winds. Maximum temperature 29 °C."
Looking on to Tuesday and the rest of the week, they added: "Hot and sunny on Tuesday before conditions breakdown overnight and on Wednesday, perhaps in a thundery way, giving cooler, cloudier, conditions thereafter. Breezy at times by Irish Sea coasts."
The Met Office added that during the extreme weather warning, covering Monday and Tuesday, locals can also expect: "Some changes in working practices and daily routines likely to be required, an increased chance that some heat-sensitive systems and equipment may fail, potentially leading to localised power cuts and the loss of other services to some homes and businesses."
They added that people are expected to travel to coastal areas such as lakes and rivers, leading to an increased risk of water safety incidents, as well as some delays to road, rail and air travel, with potential for welfare issues for those who experience prolonged delays.
