A second amber alert has been forecasted from 3pm to 6pm on Friday 21 July, with gusts of 75 to 80 km/h also likely.
Under an amber alert, speeds may be reduced and some lanes on the bridge may close.
The bridge will remain in a 4x4 configuration overnight.
Motorists are urged to drive to the conditions, look out for the electronic message boards which will indicate lane closures and reduced speeds, and stay within their lane while travelling across the bridge.
