“But we are still seeing persistent showers coming across the coast, and they’ll continue much of today and really for the foreseeable future, with a wet week ahead.”
Ms Woodhouse said Sydneysiders “could be incredibly lucky and have a sunny break” but conditions would generally be cloudy, with showers and storms on and off for the next week.
She said the ground was “incredibly wet” from Tuesday’s activity and presented the risk of further water over roads and flooding “here and there”.

“Trains will run every 30 minutes on some Sydney Trains lines, and services will be stopping at all stations, so expect longer journey times. Buses replace trains on some lines as well,” Transport for NSW said on Wednesday.
