Little Let Up in Sydney's Rain It's bad news for Sydney and NSW's Central Coast for the rest of the weekend, with wet weather set to persist across the region. The northern suburbs of Sydney and parts of the Central Coast were the target of most of the rain on Saturday. At Mona Vale Golf Course on the city's northern beaches more than 60mm of rain has been recorded since 9am, while Gosford in the Central Coast has been hit with more than 30mm. Forecaster with the NSW Bureau of Meteorology, Olenka Rudewych said the showers would continue until Monday, before easing into Tuesday. "Mostly sunny conditions are returning towards Wednesday onwards," she told AAP. But while Sydney and its surrounds will see the rain lift into early next week, for those further north more bad weather is forecast. The chance of thunderstorms are predicted on the north coast for the rest of the weekend, with moderate to heavy falls foreshadowed for Monday. People living in coastal areas north of Port Macquarie could see localised falls from 80 to 100mm during this time, Ms Rudewych said. Since Saturday morning the wet weather has seen the NSW State Emergency Service (SES) receive more than 100 calls for assistance, with volunteers responding mainly to leaking roofs and fallen trees in Sydney's north and the Central Coast. SES spokeswoman Sue Pritchard warned those taking a break over the school holidays to keep an eye on their kids. People get a bit crazy in this weather and can get cabin fever ... so make sure they (the kids) aren't mucking around in creeks and around storm water drains. Nor is it time to work out the capabilities of your 4WD through flood waters, she said.
