Adelaide hit with city's wettest November day in nearly 60 years

Heavy thunderstorms have lashed South Australia, causing flash flooding in parts of the state and resulting in Adelaide's wettest November day in 59 years.

Spectacular lightning was seen across the sky throughout the storms.

Flights were grounded while flash flooding plagued the state from Flinders Ranges to Adelaide on November 28.

By 9am, 33.6mm of rain had been recorded in the CBD, while Adelaide Airport reported 35.8 mm of rainfall.

The intense storms knocked the iconic Moby Dick sculpture free from its post at the Riverbank Christmas Lights Display.

The thunderstorm is expected to hit New South Wales over the next few hours.

A fast-moving storm swept a NSW town overnight, leaving spectators stunned. 9news.com.au reader Crystal captured an incredible lightning strike at Mullumbimby rugby club oval around 8.30pm on Thursday. The oval is also used as camp grounds.

After a week of being threatened by bushfires, residents living in Gippsland in Victoria's east have been warned to remain vigilant for flash flooding following heavy rainfall.

Farms have been seen partially underwater in the town of Maffra.

Paddocks have also been inundated with water after more than 150 millimetres of rain fell within a 24 hour period in the Gippsland region.

Residents have been told to move to higher ground in some areas of Victoria's east.

Cattle have been forced to move to their highest access point to stay dry.

Wild winds and thunderstroms also lashed parts of Victoria on October 4, keeping emergency services on their toes.

Bushfires were also threatening homes and lives in Gippsland on October 3.

Parts of NSW were also in danger from bushfires after extreme heat was recorded.

Three homes were lost and a person was rushed to hospital after a blaze near Bermagui in the Bega Valley.

It's the same area that was devastated by the 2019-20 Black Summer bushfires.

Bushfires are burning across Queensland as the state experiences extreme heat for the month of September.

Water bombing planes were called in to assist with the fight against fires that sprung up yesterday.

The Queensland Fire and Emergency Service said support from above "played an important part in bringing bushfires under control," in a Facebook post.

The post also said that observing bushfires from above helps "paint a timely picture of fire behaviour," to help firefighters plan their response.

Temperatures are expected to ease in the state tonight, before another scorcher tomorrow.

The smoke from pre-bushfire season hazard reduction burns around Sydney severely degraded the air quality in some regions.

Here, 9honey reporter Chloe-Lee Longhetti is confronted with smoke so thick in Menai it was unsafe to drive to work.

Residents have been urged to keep their doors and windows closed and limit outdoor activity during the burns.

The burns were delayed because of rain and so the smoke is expected to linger for days.

Here's the city's early morning lights highlight the smoke casting a ghostly pall over the CBD.
