Four Australians are readying for world surf title bids after officials placed the WSL Finals on yellow alert at California's Lower Trestles.
The window for the top-five shoot-out opened on Saturday morning (AEST) in San Clemente, where Tyler Wright, Molly Picklum, Ethan Ewing and Jack Robinson are all shooting for the crown.
But the call was made to delay action for at least a day, with swells from Hurricane Jova set to deliver sizeable waves at the reliable break in the next 48 hours.
Third-seed Ewing has overcome a broken back in two places suffered a month ago to shoot for a maiden title, while Robinson too has overcome an injury lay-off to sneak in as fifth seed.
Second-ranked Wright is aiming for a third world title and first since a debilitating form of chronic fatigue threatened to end her career.
Twenty-year-old Molly Picklum will have to come from fourth to win a title in her second season on the Championship Tour.
Fourth and fifth surf in a sudden-death heat to begin proceedings, the winner progressing to face the higher-ranked surfer and the final a best-of-three affair against the top seed.
