Practice rounds at The Masters have been pushed back a couple of hours due to lightning and heavy rain on the eve of the tournament's 81st edition getting underway.
Organisers were left with little choice but to evacuate the course at 10am local time, which could also affect the traditional pre-tournament Par 2 contest.
As well as seeing matters on the course disrupted, flights to the closest major airport have also been temporary halted, with severe weather forecast for a number of Southern States.
The weather is due to improve slightly in the early afternoon but more rain, as well as winds of up to 60mph, has been predicted for later in the day.
A statement released by Masters organisers read: "The warm front is moving through Augusta with rain and thunderstorms to the west. The front lifts to the north and will allow for a break in the weather with sun peeking through the clouds.
"But the sunshine will further destabilise the atmosphere and lead to additional thunderstorm development towards the middle part of the afternoon.
"Thunderstorms are expected to become severe and conditions will be favourable for heavy rain, frequent lightning, hail, damaging winds of 40-60mph, and tornadoes."
