Meanwhile, parts of Sydney copped it on Saturday night, with Narellan in the south and Malabar in the southeast hard hit by torrential and winds gusting close to 100km/h, and minor flooding expected in the west on Sunday. The SES took about 85 calls for help from Narellan. "There was a retirement village out there where a number of the units had some minor roof damage," the SES spokesman said. One home at least out there had some very extensive roof damage, with two bedrooms destroyed. Thunderstorms and destructive winds, described by locals as "mini-tornadoes" hit Sydney's eastern suburbs, damaging an RSL club and a primary school and ripping part of the roof off Fox Studios. The SES received about 40 calls for help from Malabar, Chifley and Randwick in the city's east. They were among 1200 calls to the SES overnight, from the north coast, down to Sydney and the Illawarra region. About 80 homes and a fire station were damaged at Kiama on the state's south coast. And there were two rescue missions during the night, one at Toongabbie and another at the Central Coast, taking the total from this spate of wild weather to 66. About 20,000 people remained isolated along the NSW coast on Sunday, the SES said. Electricity supplier Ausgrid said about 17,000 people were without power throughout the night in Sydney, the Central Coast and the Hunter regions. Kempsey Shire Mayor Liz Campbell said the predicted peak would be just below the 2001 flood which would mean shops and some houses would have water in them. Evacuation centres had been opened at two high schools and an Anglican hall in Kempsey.
