FLASH floods, thunderstorms and hailstones may be heading to East Lothian over the next two days.
The Met Office has issued a yellow warning for the county saying some areas could see torrential rainfall with up to 30mm in an hour.
It said the soaring temperatures and humidity meant warnings had to be issued with the worst of the weather expected to hit the county overnight tomorrow.
A spokesperson for the Met Office said: "While most places will miss the worst, please be aware of the risk of flash flooding.
"Frequent lightning, large hail and strong winds could be additional hazards.
"All of this could lead to some flooding of homes, businesses and transport networks. Disruption to power is also possible."
The yellow warning comes into effect from 7pm tomorrow and will remain in place until 6pm on Wednesday.
