Wild weather to hang about for another day

Sydney is in for another day of wild weather, with the downpour causing some delays on major roads during the morning commute as motorists are urged to slow down in the wet.

A total of 20 millimetres of rain is expected.

Although showers will hang about for most of Wednesday, winds are expected to ease but there is the chance of a thunderstorm during this afternoon and evening.

Large and powerful surf conditions are expected to be hazardous for coastal activities such as rock fishing, swimming and surfing.

Thursday will be slightly warmed at 21 degrees but the chance of any rain remains high at 80 per cent, though only up to 6mm is predicted to fall.
