Another typhoon is starting to gather momentum and so are Kiwi 49erFX sailors Alex Maloney and Molly Meech at the Enoshima Olympic Week regatta in Japan.
The Rio Olympic silver medallists had a poor first day by their standards but roared back with three firsts and a second place on day two.
The 22nd typhoon to hit Japan this year is due to make landfall late on Sunday, although it's not expected to be as powerful as last weekend's Typhoon Lan.
Maloney and Meech have jumped from seventh to first, level on points with the German pair of Victoria Jurczok and Anika Lorenz.
New Zealand's Erica Dawson and Kate Stewart round out the top three.
"We had a pretty average start to the regatta but it was also really good learning," Meech said.
"It was cool to suss it out and try to get a feel for what it's going to be like."
Maloney likened it to sailing on Auckland's North Shore, with a fresh breeze and reasonably flat water at the venue for the 2020 Tokyo Olympics.
Paul Snow Hansen and Dan Willcox also made a big move up the leaderboard of the men's 470, three top-five finishes - including a win in the first race of the day - propelling them into fifth.
In 49er racing, Logan Dunning Beck and Oscar Gunn banked three top-five scores and are level on points with James Peters and Fynn Sterritt of Britain in second place.
Tom Sanders scored his second win of the regatta and is third overall in the Laser fleet, only seven points off leader Lorenzo Brando Chiavarini of Britain, while fellow Kiwi Sam Meech is fourth.
