Southern Queensland is on alert for severe thunderstorms that could be the worst of the season.
A severe thunderstorm warning has been issued for damaging winds and large hailstones.
Emergency Management Queensland is warning residents to stay indoors and be wary of fallen trees and power lines.
The Bureau of Meteorology says towns in the Darling Downs, including Toowoomba, and the Granite Belt, towards the NSW border, are in the firing line.
Heavy rain, winds of up to 90km/h, and hail are also forecast for Brisbane and the Gold and Sunshine coasts.

Bureau of Meteorology forecaster Michael Knepp says the storms have the potential to be the worst of the season.
"There will be damaging winds, possibly destructive winds and the possibility of hail and of course storms bring heavy rainfall," he told AAP.
It's anticipated the storms will develop in the Darling Downs and Granite Belt by 1pm. They are expected to roll into Brisbane later in the afternoon.
Mr Knepp said a trough moving through the southern part of Queensland had created enough moisture in the air to cause potentially damaging conditions.
Those conditions are expected to ease late Tuesday evening as the southerly change begins moving up the coast towards Fraser Island.
