The Bureau of Meteorology has cancelled a severe thunderstorm warning for the Sydney metropolitan and surrounding area that it had issued on Tuesday night.
About 9.15pm, the bureau warned that it had detected severe thunderstorms on the weather radar near Parramatta, Cessnock, Bucketty and Berry.
It advised Sydneysiders to prepare for heavy rainfall, large hailstones and damaging winds.
“These thunderstorms are moving towards the east to northeast,” the warning said. “They are forecast to affect Kiama, Penrith and Kurri Kurri by 9:45pm and Hornsby, Liverpool and Maitland by 10:15pm.”
At 8pm, residents in Metropolitan, Illawarra and parts of Mid North Coast, Hunter, Central Tablelands, Southern Tablelands, Northern Tablelands and South Coast Forecast Districts were warned to be prepared for the risk of flash flooding, large hailstones and damaging winds over the next several hours.
“Locations which may be affected include Penrith, Parramatta, Wollongong, Nowra, Bowral and Katoomba,” the BOM said in a statement.
However, close to midnight, the bureau cancelled the warning, saying thunderstorms had eased across the state.
“Humid and unstable air triggered thunderstorms today, however they have now eased,” it said.
