The summer of storms continues for NSW with large swathes of the state – including the western Sydney metro region – facing another bout of thundery weather.
The Bureau of Meteorology issued a severe thunderstorm warning for western parts of the metropolitan area, the Illawarra and a region stretching from Goulburn to Tibooburra in the state's far north-west.
The alert said the storms were "likely to produce heavy rainfall that may lead to flash flooding, damaging winds and large, possibly giant hailstones over the next several hours".
David Wilke, a bureau duty forecaster, said Camden in Sydney's south was one area in the line of the storms.
"The severe ones at this stage are staying mostly out of the Sydney metro area," Mr Wilke said.
However, there is some risk "we could see a storm in Sydney" later on.
Earlier on Wednesday afternoon, parts of the Blue Mountains copped hail and rain as a storm moved northwards over the region.
While the bureau said the prospect of storms had eased, "further severe thunderstorms are still possible".
Eastern NSW, in particular, has endured a very active storm season.
Among the most severe was a storm that hit Sydney on December 20, prompting the Insurance Council of Australia to declare the event a "catastrophe". By the following day, some residents had already lodged some 25,000 claims for losses particularly from hailstones of more than $125 million, with the final figure likely to be much higher.
