Fourteen flood warnings remain in place across the state.

Earlier today, meteorologist Pieter Claassen said a trough separate to Imogen was moving through the west of the state and would intensify this afternoon.

"We'd be seeing that system make its ways to the southeast corner around the early evening on Wednesday, with thunderstorms possible to follow suit," Mr Claassen said.

"We could see isolated falls in excess of 60-80mm plus.

"We should expect those falls to hang around overnight and even early into Thursday, though we shouldn't expect prolonged thunder activity."
