"In the last 24 hours, we've seen some widespread showers and thunderstorms through the length of NSW," said BOM's acting NSW state manager, Grahame Reader.

"The storms that we've had are localised and slow-moving, so that means the rainfall pattern has been a little sporadic ... We've seen a number of centres in the north and north-eastern parts of the state recording over 100 millimetres." Bulahdelah recorded 112 millimetres and Bundarra notched 105 millimetres, the latter the highest in the area since 2011. Commuters queued at the light rail stop at Central Station due to wet weather.

WaterNSW is monitoring the rainfall and said there was a minor increase in flow in the Kedumba River to Warragamba Dam.

A statement from WaterNSW said there were no "current concerns about rain washing ash or other debris into dam storages from catchments affected by the bushfires at this point". WaterNSW is conducting an inspection of Lake Burragorang, which supplies about 80 per cent of Sydney’s water through Warragamba Dam, to assess any other potential impacts and to take water samples for analysis. Since Wednesday, the SES has received over 320 calls for assistance, most about leaking roofs. "We haven't had anything of particular significance," said acting NSW SES Commissioner Paul Bailey. "We're not expecting there to be significant issues going forward."

Mr Bailey said that people in fire-affected areas should be "vigilant, but not terribly alarmed" of the potential of falling trees, debris in bodies of water, and an increase chance of flooding due to a lack of vegetation. "This rain is welcomed in those areas, so we are expecting there to be only a few issues regarding this rain going forward," Mr Bailey said. The falls could be heavier on Saturday, with the prediction of 20-50 millimetres potentially the most rain since mid-September. At 6pm, 89 fires were still burning across NSW, with more than 30 yet to be contained. NSW RFS Deputy Commissioner Rob Rogers told Channel Seven's Sunrise program: " We have had rainfall on most fires now, at least 10 millimetres.
