Curtis was at 22-under-par through 16 holes when the Booz Allen Classic was suspended Monday for the second consecutive day because of heavy rain and thunderstorms.
The PGA TOUR is looking at its first Tuesday finish since the 1980 Tucson Open, although showers and thunderstorms are in the forecast for tomorrow as well.
Of course, the outcome is pretty much a fait accompli.
Looking for his first win since claiming the 2003 British Open as a rookie, Curtis holds a seven-shot lead over four others.
Only two of the players closest to Curtis are still on the course.
Nick O'Hern (17 holes) and 1996 champion Steve Stricker (16 holes) will return to the TPC at Avenel at minus-15. Billy Andrade completed a 7-under 64 Monday and shares the clubhouse lead with Padraig Harrington (66) at 15-under-par 269.
The final round was originally scheduled to resume at 8:00 a.m. local time on Monday, but soggy course conditions pushed that start time back until 11:15. Players returned to the course for about five minutes before play was suspended again until 12:20.
The horns sounded once more around 1:45, and the round was eventually suspended for good more than three hours later.
Curtis held an eight-shot lead through 11 holes and had just knocked his second shot at the par-4 12th into the water when play was halted on Sunday.
He finished the 12th with a double bogey on Monday, then recovered one of those shots with a birdie at the par-4 16th.
At 22-under-par, Curtis is on pace to shoot a 262 -- which would break the tournament scoring record of 263 set by Andrade and Jeff Sluman in 1991 and matched by Adam Scott in 2004.
Standing in the way of that record: a 29-foot par putt for Curtis on the 17th green when play resumes on Tuesday.
Since his win at Royal St. George's three years ago, Curtis has made just 32 cuts in the 66 events on the PGA Tour calendar in which he made a start. His best finish during that period was third place at last year's Western Open.
During one particularly poor stretch, Curtis missed eight straight cuts early in the 2005 season.
'Hopefully [a win] will be the start of something good for me,' Curtis said Sunday.
Ben Crane and Jeff Gove are in the clubhouse at 14-under-par 270 following rounds of 66 and 68, respectively. They currently share sixth place with Robert Allenby, who is through 17 holes.
