Heavy rain lashed the Sedgefield CC course in the early afternoon with the decision to cancel play for the day coming at 5.15pm.
Golfers will return to the course at 8am Sunday to complete their third rounds with the final round scheduled to begin around 11am local time.
The final round will be played in groups of three and using both tees in an effort to avoid a Monday finish.
Snedeker, who opened with the Tour’s 10thsub 60 round when he posted a 59 Thursday, was at 16-under for the tournament through seven holes when play was called, good for a three-shot lead over a charging Brian Gay.
Gay is 6-under for his round through 12 holes and holding second alone, one ahead of Trey Mullinax, Keith Mitchell, C.T Pan and D.A Points sharing third.
The two Australians who made the cut, Aaron Baddeley and Cameron Percy, will both likely be glad of the break in play as both were struggling in the third round.
Baddeley was T10 at the start of the day but more importantly projected 126th on the FedEx Cup standings and one spot outside full exemption for 2019.
Needing a good weekend to climb into the all exempt category he got off to a poor start with a bogey at the second and while he recovered with a birdie at the next gave away a further two strokes with a clumsy double bogey after losing a ball off the 9thtee.
The four-time Tour winner had just holed form 20 feet for a birdie at the 11thwhen play was halted but will now have the chance to regroup overnight.
He is currently 7-under and T35, the same score as Percy but 25 places further down the leaderboard than where he began the day.
Percy has little chance of qualifying for the top 125 but at 169thin the FedEx Cup will be trying to climb inside the top 150 who earn partial exemption for 2019.
He will face a tricky shot from the left rough on the 18thwhen play resumes in the morning having already driven when the horn sounded.
