The RACQ is warning motorists in bayside and riverside suburbs to avoid parking in low-lying and flood-prone areas as higher than normal high tides have been expected since yesterday.

RACQ spokesperson Lucinda Ross says the Bureau of Meteorology is predicting a peak tide of 2.7 metres on Thursday. 

Mrs Ross says people driving through suburbs such as Albion and Newmarket should keep in mind there may be water over the road, adding it is never safe to drive through flood water.
