Severe weather warning for Canberra for heavy rain, strong wind and possible flash flooding cancelled

It had earlier warned of damaging winds and heavy rainfall that could lead to flash flooding.

The bureau has forecast a very high chance of rain heading into the weekend, with 35 to 50mm of downpour expected.

Friday afternoon is expected to have easterly winds of 15-20km/h, shifting to northwesterly winds at about 20-30km/h.

Rain on Saturday and Sunday will likely keep people indoors, though the downfall is tipped to decrease, with Saturday getting up to 15mm of rain, and up to 4mm to close out the weekend.

ACT Emergency Service Agency (ESA) teams have been notified of 12 storm-related incidents overnight, all of them leaking roofs.

An ESA spokesperson said they were still tending to six of these, and that crews conducted assessments of damage and would assist with temporary repairs.

The spokesperson encouraged people to be cautious of falling trees and powerlines as the wet weather continued.

On Thursday, forecaster Gabrielle Woodhouse said the weekend would feel "like a little blast of winter".

Meanwhile, NSW is in for another day of heavy rain and thunderstorms ahead of conditions predicted to ease over the weekend, as some parts receive more than a month's worth of rain in a matter of days.

The Bureau of Meteorology has warned sheep graziers around the state the weather may be so bad that their stock might not survive the day.

Colder temperatures, showers, and gusty west to northwesterly winds are expected around the state on Friday, continuing a cold and wet week that has delivered intense rainfall and thunderstorms.

On Thursday Dubbo was hit with 40mm, with most of it falling in just 30 minutes.

Narrabri already received more rain than it typically expects for the month of November after 76mm fell overnight on Wednesday into Thursday.

The heavy rain trapped an empty school bus and three 4WD between two fast-rising creeks near Narrabri on Wednesday afternoon, however the SES was "heartened" to see they called for assistance and did not try to drive through the floodwaters.

Tibooburra, near the NSW, South Australia and Queensland borders, was hit with a 104km/h wind gust shortly after midday on Thursday, which also brought an intense torrent that dumped 13mm of rain in 20 minutes.

Flood warnings are in place for the Lachlan River at Nanami, and for the Gwydir and Mehi Rivers at Gravesend, Pallamallawa, Yarraman Bridge and Moree.
