The Civil Protection Department has urged motorists to avoid low-lying areas tonight because of the possibility of flooding.
It said heavy rainfall is forecast overnight over parts of the Maltese islands.
Motorists should drive with caution, especially when visibility is reduced because of the rain, and they should not park in flood-prone areas.
Flooding was reported in Msida and Birkirkara this afternoon, with several cars stalling because of the rising water.
