Storms smash Sydney in another day of wild weather

Sydney and other parts of NSW are being smashed by yet another storm.

Weather warnings for severe thunderstorms have been issued all the way from the Northern Beaches to the Illawarra Coast with the BOM warning of one massive storm cell merging.

Hail and "squally" winds are also possible, forecasters say.

Hail fell in Camden in the city's south-west, carpeting gardens in white.

Sydney's Harbour Bridge almost disappeared in the dreary mist.

Thursday in the city will see a return to sunny weather, with temperatures expected to hit 30 degrees.

Showers will then return from Friday and into the New Year.

Multiple people have died in storms in Queensland and Victoria over the past few days, as wild weather hit Christmas.

Three people have been found dead after a large boat with 11 people on board capsized on Boxing Day near Brisbane.
