At 1:13pm the a fallen tree on the M1 Princes Motorway (just past Picton Road) at Bellambi Creek was causing closures northbound due to a fallen tree. Motorosts should allow extra travel time.

As of 2pm, the State Emergency Service has received 47 calls for assistance in the Illawarra since late Monday. Public Affairs Officer Ilana Pender-Rose said they were mainly for trees down because of strong winds and plenty of damage to roofs.
She said the SES advises people to park their car under cover during severe weather events and tie down anything in their backyards which could blow away, like trampolines.
Albion Park had recorded wind gusts up to 92 km/h at 9:12am, with gusts about 85 km/h elsewhere around the Illawarra.
A severe weather warning remains in place for NSW coast - from the South Coast and Illawarra up to Coffs Harbour - on Tuesday.
An intense Tasman low and an associated cold front is producing strong, gusty winds, which are also whipping up heavy surf conditions - making coastal activities dangerous, and bringing the potential for coastal erosion.
