Weatherzone: ACT storm tracker

Up to 50mm of rainfall could fall over the ACT region in the next 24 hours despite the cancellation of a severe weather warning.

The Bureau warning was issued for the territory and south-east NSW on Thursday afternoon, but was lifted by authorities at 4.16am on Friday morning.

Canberra recorded 24mm of rain in the 24 hours to 9am Friday, and can expect between 10 and 50mm through the rest of the day.

Tuggeranong was drenched with 48.6 millimetres of rain in the 24 hours to 9am Friday.

Weatherzone meteorologist Kim Westcott said Canberra is well on the way to reaching its April rainfall average of 45mm.

She said it is difficult to tell how much rain Canberra will receive given instability in the region and that it will depend on whether thunderstorms materialise.

“Saturday could be a little miserable in Canberra although conditions should improve by Sunday once the low pressure system begins to move north,” she said.

The rain should ease by Saturday with a few showers expected before clearing completely on Sunday and Monday.

As of 2.30pm, the ACT State Emergency Service has responded to 43 calls for assistance since 7am Friday.

Only two calls were made to the ESA overnight before 7am.

An Emergency Services Agency spokesman said the majority of calls related to leaking roofs, fallen branches, or minor flooding incidents and the calls came from all over the Canberra region.

The SES warned flash flooding might still occur in some areas of the ACT despite the cancellation of the severe weather warning.

The SES also also warned people to take care over the next day, advising residents to check if their gutters and rains were clear and reminding Canberrans to have regular roof maintenance.

The deluge of rain has caused the closure of dams, reserves and roads around Canberra.

The Tidbinbilla Nature Reserve visitor centre has been closed after minor storm damage although the reserve is still open to the public.

The Googong Dam is closed to boats as is southern access to the Googong Foreshores.

The Angle Crossing in Tuggeranong is now closed to traffic and police are urging motorists to take additional care on wet roads. 

The campsite for the Mont 24 hour mountain bike race has been closed due to heavy rain overnight.

The event, which is the largest of its type in Australia, is based in the East Kowen Forest near Queanbeyan.

"In the interests of campers and the land managers we have made the decision to close the campsite until the rain event passes," said a spokesperson.

Weatherzone meteorologist Brett Dutschke said on Thursday that there was a good chance the ACT and southern NSW would see the heaviest falls they've had in one or two years.

"The heaviest falls will occur over [Thursday night] and [Friday] morning and between now and Saturday morning there's likely to be widespread falls of 30 to 100mm," he said.

Mr Dutschke said thunder and lightning was unlikely however, given the thickness of the cloud, the biggest issue could be a huge amount of rainfall.
