With flood warnings in force locally, organizers kept spectators out for safety reasons until after the session had finished.
The governing International Automobile Federation (FIA) decided, however, that it was safe for the drivers to venture out and the session started on schedule despite the poor visibility and heavy spray.
With Friday's second practice entirely washed out, and qualifying looking uncertain with heavier rain forecast for later, the final session could prove crucial for Sunday's potentially title-deciding race.
While qualifying was still scheduled for 1400 local, it could also be held on Sunday if conditions are too bad on Saturday. Failing that, final practice positions will be used to determine the grid.
If so, Hamilton will be even more the favorite to take his third title on Sunday.
The Briton lapped with a best time of one minute 59.517 seconds, with Ferrari's Sebastian Vettel second fastest on 2:00.380. Nico Hulkenberg was third for Force India and Finland's Valtteri Bottas fourth for Williams.
