A giant puddle of water cleared after causing traffic chaos on the Southeastern Freeway

Peak hour commuters have been disrupted by a giant puddle blocking a lane on the Southeastern Freeway as the BOM cancels much of its severe weather warnings.

A pool of water on the Southeastern Freeway has disrupted traffic during peak hour.

Cars were queued behind the giant puddle blocking traffic heading away from the city near the Mt Barker exit about 3.20pm.

Traffic was down to one lane while the puddle blocked the road, with one car unsuccessfully attempting to drive through it.

Police provided traffic management while SA Water were called to the scene.

The drains were cleared about 5.30pm and the puddle dissipated.

It comes as the Bureau of Meteorology issued multiple warnings earlier Monday, with severe thunderstorms expected across the state.

The warnings have since been cancelled across the Adelaide region but the situation will continue to be monitored and further warnings will be issued as necessary.

About 21mm of rain was recorded at Athelstone in half an hour to 3.05pm with about 19mm in the same time frame at Verdun.

The State Emergency Services advised South Australians to keep clear of fallen power lines, beware of debris on the road and do not drive through flood water.
