The Masters has been suspended during the third round with Brooks Koepka leading by four shots.
Play was suspended at a drenched Augusta National following a sustained downfall throughout Saturday.
Koepka led Jon Rahm by four shots, with amateur Sam Bennett a further three strokes behind.
There was then an evacuation siren sounding around the property, alerting the spectators to leave the course.
A statement read: “Due to inclement weather conditions, the third round has been officially suspended for the rest of the day as of 3:15 p.m. EDT.”
The break in play should help the leaders, especially Rahm, after a lengthy day saw the Spaniard finish half his second round after play was suspended on Friday too.
