Thunderstorms, hail and damaging winds have prompted severe weather warnings for the regions surrounding the ACT.
Meteorologists are expecting storms to continue to hit parts of Canberra in the next hour.
But so far the capital has avoided the severe weather warning issued for much of NSW.
A trough of low pressure has caused an "extensive line" of thunderstorms stretching right across NSW, meaning heavy rainfall and dangerous weather conditions this afternoon.
Hail has been reported in parts of Canberra, including at Floriade.
ACT Policing have warned of dangerous conditions on the Federal Highway north of the ACT border due to hail and water on the road.
Residents in much of NSW are being warned of dangerous flash flooding and hailstones, and are being urged to keep clear of drains, creeks, and fallen power lines.
That warning has not yet been issued for the ACT, but Bureau of Meteorology meteorologist Nick Bright said that could change at any point.
"At the minute [the warning] covers everywhere around us, but it doesn't actually cover Canberra itself," he said.
"You need to keep checking the [Bureau of Meteorology] website to keep updated, right now it's not on us, but I would expect it might change in the future."
The Queanbeyan State Emergency Service has warned residents to stay indoors, away from windows, creeks and drains.
The bureau expects the storm activity to weaken by this evening.
