The BOM has issued a warning for severe thunderstorms to hit south-east Queensland and north-east NSW on Tuesday and Wednesday.
The agency noted that the storms could affect areas such as Gladstone in Queensland as well as the Hunter in NSW.
The agency noted that the most severe storms are expected to hit the Northern Rivers and Mid North Coast regions of NSW. They will then move into south-east Queensland.
Miriam Bradbury, a senior meteorologist, said that the Gold Coast and Brisbane may not be affected by the storms.
The agency noted that the most dangerous weather will be accompanied by large hail and powerful winds.
Although brief downpours may occur in some areas, such as on the Queensland border, the storms are the main risks.
The BOM also warned that the powerful winds could cause tree limbs to fall and create hazardous driving conditions.
The combination of heavy rain and large hail can reduce visibility. According to Bradbury, the storms are expected to develop as a trough moves up the Central and Southern NSW coast.
These storms are expected to hit the coastal regions of NSW during the afternoon and evening. They will also affect south-east Queensland and north-east NSW.
The storms are expected to develop as the strong southerly winds push through the trough line. They will then affect south-east Queensland and the central and southern regions of the state.
These storms are likely to continue until Wednesday. Although the weather will be less likely on Thursday, coastal showers are possible in NSW and southern Queensland.
According to Bradbury, the situation is still unfolding. She said that the agency is closely monitoring the development of the thunderstorm.
