A flood alert has been issued for the Sunshine Coast and hinterland as heavy rain intensifies in south-east Queensland.
The Bureau of Meteorology warns overnight rainfalls of over 100mm on the Sunshine Coast are likely to cause flash flooding and stream rises.
SES crews were called out to carry out precautionary sandbagging operations at Bli Bli on the Sunshine Coast overnight, while there were a small number of calls for leaking roofs near Caloundra and in Brisbane's north, an Emergency Management Queensland (EMQ) spokesman said.
"There's more rain on the way through that part as well, which is going to push through Brisbane later today," senior forecaster Vikash Prasad said.
Flash flooding is also possible on the Gold Coast later Monday as the heavy rain shifts down the coast, he said.
The heavy rain is the result of a trough moving onto the coast from the east, which has also caused dangerous surf conditions for much of the south-east.
Beaches on the Sunshine Coast and Gold Coast will again be closed on Monday.
The rain is good news for the region's parched dams, with the Somerset catchment north of Brisbane receiving the best of the overnight falls.
"This rain is starting to push through the north part of the Somerset catchment, and the Wivenhoe dam area has started to receive some falls," Mr Prasad said.
SEQ Water has said consistent falls of up to 45mm are needed before levels begin to rise.
As of 6am (AEST) Monday the Wivenhoe catchment had received up to 15mm, the bureau said.
The rain is predicted to weaken to showers on Tuesday.
