The unit's crews attended seven jobs with five related to fallen trees and two for damaged roofs.

The jobs were mainly in the areas of Yatte Yattah, Conjola and west of Milton in Croobyar and Woodstock, an Ulladulla SES Unit spokesperson said.

There will no injuries.

Wind gusts peaked at 59km/h at the Ulladulla Area Weather Station between 8am and 8.30am on July 11.

Peak gusts slowed over the morning before reaching 52 km/h at 11.32am and 50km/h at 1pm.

With winds expected to continue to lash the area over the next day or so the SES has again reminded residents to secure or put away loose items around your house, yard and balcony; move vehicles under cover or away from trees and to keep at least eight metres away from fallen power lines or objects that may be energised, such as fences.

A cold front is currently crossing southern NSW, with a second cold front forecast to cross the state overnight Friday into Saturday morning.

"We are expecting winds to abate slightly tomorrow, but the second cold front is likely to keep the atmosphere stirred up," the spokesperson said.

Power was restored to more than 500 properties between Ulladulla and Lake Conjola about noon. Five customers remain affected in Milton.

You can report fallen power lines to Endeavour Energy (131 003) and for emergency help ring your local SES Unit on 132 500.
