With nine regular first-graders sidelined through injury or Origin duties, the Storm put together an impressive defensive display and scored the only try of the match late in the second half.
The result sees the competition favourites maintain top position on the NRL ladder.
In a match played in greasy conditions, and dotted with numerous handling errors from both sides, the Warriors were able to take the lead with a penalty goal in the ninth minute through centre Tony Martin.
The Warriors had the chance to go further ahead when they were awarded a penalty in easy kicking range just before the half time break. Surprisingly, the home side opted to take the tap, and lost possession soonafter thereby passing up a handy four point lead.
The second half saw more possession go the way of the Warriors but the Storm defence held firm with hooker James Aubusson putting in a sterling display with over 50 tackles.
An effective kicking game from half back Cooper Cronk kept the visitors in the match, while new Melbourne recruit and second row forward Clint Newton was also a standout just wide of the ruck both in defence and with the ball in hand.
A try to lock Jeremy Smith in the 71st minute gave Melbourne a valuable 4-2 lead - which in the conditions proved to be a match winner.
Warriors skipper Ruben Wiki tried to rally his troops but in the end it wasn't enough, the Warriors crashing to their sixth successive loss and in danger of losing touch with the top eight.

23 min: Storm forced into a second line drop out but the Warriors unable to complete the set, the ball being passed into touch.
30 min: Half an hour gone we have match dotted with a few handling errors from both sides. Rain easing but still slippery conditions. A close tussle mainly being played in the middle of the park, but the Warriors having a little more field position and possession.
34 min: Again, the Warriors pressing and the Storm line holding but forced into consecutive line drop outs.
35 min: Warriors get a penalty right in front after a player is held back by a defender. They take the tap, amazingly passing up a gift two points. Warriors then lose possession. Great defence from the Storm.
Half time: Warriors 2-0 A real arm wrestle at times with the Warriors more dominant in the first half, throwing the ball around and quite entertaining albeit slightly disorganised. Unfortunately, they were unable to convert it into any four-pointers. The decision not to take the penalty goal in 35th minute was a little baffling considering the conditions and that points are hard to come by. The Storm looking very solid in defence with Cronk employing a long and high kicking game when they have the ball. Both sides guilty of handling errors in the greasy conditions. Anyone's game.
