Sydney awoke to rain this morning, after experiencing the most rainfall in a 24-hour period since September last year. And it’s going to get even wetter this weekend, with a coastal trough in northern NSW set to move south late this afternoon. Up to 130 millimetres of rain is forecast to fall in Sydney today, with up to 90 millimetres on Saturday and 80 millimetres on Sunday. The Bureau of Meteorology (BoM) has issued a severe weather warning for much of coastal NSW, with flash flooding possible. It’s also warning of damaging winds of up to 90kmh tonight. There’s also the possibility of thunderstorms. Rain is expected to continue until at least Thursday next week.

Showers have already caused issues across Sydney, with lane closures at Boundary Street in Roseville, Victoria Road in Drummoyne, Pennant Hills Road in Thornleigh, Hume Highway in Yagoona and Pittwater Road in Dee Why due to flooding.

Some train lines – including the T1 North Shore & Western line and T2 Inner West & Leppington line – have been delayed due to slower boarding times caused by the wet weather. In the west, the Parramatta weir has overflowed, causing buses to replace ferries between Parramatta and Rydalmere. And in the Blue Mountains, the road to the Jenolan Caves has been closed due to landslide concerns.

The BoM advises people to park their cars away from trees, secure loose items around their houses and balconies, and keep clear of creeks and storm drains.
