After Friday's stormy deluge, parts of Sydney copped another drenching on Saturday night and there's more wet weather on the way. Over the last few days a slow-moving low pressure trough fed by moist southeasterly winds has brought rain and storms to the Sydney Basin. The North Shore and Northern Beaches copped the brunt of Saturday's rain, with widespread falls of 20-50mm. Castle Cove had 44mm to 9am on Sunday, adding to Friday night's deluge to bring their two-day total to 200mm. The city had 41mm to 9am on Sunday, pushing the weekly total over 130mm, more rain than the city has seen in last four months combined. This makes it the wettest November week in 16 years after what was the driest July-to-October in 11 years. Such a drastic turn around from dry to wet weather at this time of the year hasn't been seen in Sydney since the 1950s. Other notable two-day totals include 125mm at Avalon, 53mm at Terrey Hills and 71mm at Frenchs Forest. But while northern locals are mopping up, those in the southwest may be wondering what the fuss is about, with places like Campbelltown and Camden having seen less than 10mm. A low pressure system has now developed off the Hunter Coast and is expected to edge closer to the coast during Sunday afternoon and evening. This system will cause showers to become heavy on Sunday night. Once again the Northern Beaches and North Shore are likely to see the heaviest falls, with the potential for a further 50-100mm over the next 48 hours. The low will also deliver powerful winds and dangerous surf, with a severe weather warning in place for Sydney, as well as the Hunter, which is expected to cop the full brunt of the low. By Tuesday conditions will ease, with sunnier skies and warmer conditions. The brighter weather won't last long though, with more rain arriving on Wednesday night or Thursday as another trough moves over the state.
