Parts of north Queensland are on flood alert with heavy rain triggering a landslide and causing school and road closures.
The Mackay region has been the worst hit by thunderstorms that have drenched Queensland since the weekend, with Paget copping 304mm in a 24 hour period up to 9am on Monday.
The downpour flooded the Mackay Christian College campus and grounds - forcing the school's closure on Monday - along with roads throughout the region.
Heavy rain has also been blamed for causing a landslide near Sarina, south of Mackay, that restricted access to a northbound lane.
The State Emergency Service have helped Mackay residents sandbag their properties.
The Bureau of Meteorology says showers and thunderstorms are expected to continue throughout the state until Wednesday.
Senior meteorologist Helen Reid the rains could cause more rivers to break their banks.
Drivers have been urged not to try to cross flooded areas with the RACQ saying that about 280 roads had been closed due to heavy rain at 11am on Monday.
"Heavy falls from thunderstorms could lead to flash flooding in addition to the riverine flooding throughout much of southern and eastern Queensland at the moment," Ms Reid said.
"Many rivers are in flood, lots are at moderate level, some are at major as well, particularly in the south.
"Rivers that don't already have a minor flood warning have a flood watch covering most of eastern and southern Queensland."
Severe thunderstorms with heavy rainfall, she said, are possible across the state except the southeast and far west in the next 48 hours.
The Central Highlands near Rockhampton and the central west are expected to be some of the hardest hit areas.
BOM also "wouldn't rule out the possibility" of damaging wind gusts and large hail in southern Queensland in the coming days.
