DON'T forget to pack a primrose and blue rain mac and umbrella when you head to the Grand Final. 

Fans are facing the strong possibility of getting drenched on their way into the ground as Warrington Wolves take on Wigan in the Old Trafford final. 

Kick off is 6pm for the match tomorrow, Saturday, with a 75 to 82% chance of rain between 2pm and 6pm. 

Gusty winds are also predicted between 3pm and 5pm as Storm Callum sweeps across the country. 

While the high winds will have dropped by the time the game kicks off, light rain is predicted throughout the match and for the journey home. 

TRAVEL: 

Don't forget there's a train strike this weekend so there will be no Northern Rail trains after the game. 

Limited services will be run by East Midlands Trains and Arriva Trains Wales.

There is some good news for fans travelling to the game as ticket holders can get free tram travel on the day.
