A severe weather warning has been cancelled for the ACT, as heavy rainfall and damaging winds eased on Sunday afternoon.
Earlier, the Bureau of Meteorology issued a severe weather warning that included parts of the ACT.
The warning has since been cancelled, however a severe thunderstorm warning remained for parts of NSW.
The bureau will continue to monitor the situation and will issue further warnings if necessary.
Lightning was reported in southern parts of the ACT at around midday on Sunday and a storm passed through the territory in the early afternoon.
A second storm was possible, likely closer to 6pm, that could bring heavy rain or damaging wind gusts, Jake Phillips, senior meteorologist at the Bureau of Meteorology, said on Sunday afernoon.
"As is always the case with thunderstorms, we can't guarantee that you're going to see [them] in any given location, but they will be in the region and there is potential for them to become severe as well," he said.
While there could be no guarantees, the ingredients for a thunderstorm were in the atmosphere, Mr Phillips said.
"We've got a lot of warmth and a lot of moisture and they're a couple of the key ingredients we need for storms," he said.
"That's all being kicked off by a trough of low pressure that's moving across from western NSW towards the east and across the ACT."
Mr Phillips said Canberrans should keep an eye on the weather radar and for any further warnings.
