Rain threatens to ruin T20 World Cup final

Victoria's unpredictable weather is threatening to ruin the blockbuster Twenty20 World Cup final at the MCG.

Up to 25mm of rain is forecast for Melbourne on Sunday when resurgent Pakistan will face India or England in front of more than 90,000 people.

Most concerning for organisers is showers and a predicted thunderstorm are expected to arrive in the afternoon and evening. The match is scheduled to begin at 7pm AEDT.

To constitute a match a minimum of 10 overs is required per team, unlike the group stage when only five overs per-side was needed to complete a game.

If the final is washed out the ICC has left Monday as a reserve day with play beginning at 3pm.

But Melbourne's weather is looking just as ominous then, with a 95 per cent chance of showers and up to 10mm of rain forecast for Monday.

If play starts on Sunday and is later stopped the game will resume on Monday from where it left off.

Melbourne has an indoor venue, Marvel Stadium, only 5kms away from the MCG but there is no chance the ICC will consider moving the game to the Docklands ground.

In the event rain washes out any prospect of play the competing teams will be forced to share the T20 trophy in what would be a bizarre situation.

It comes after three games at the MCG during the group stage were abandoned due to wet weather and another match was shortened because of rain.

Australia's monster showdown with England at the famous venue was washed out without a ball being bowled as the teams shared the points.

The hosts missed out on qualifying for the semi-finals and defending the title they won in the UAE last year on net run-rate.

The opening match of the tournament at the MCG was an all-time classic as India defeated Pakistan on the final ball in front of a pulsating crowd of 90,293.

A rematch between the famous rivals in the final could mean the MCG's record attendance at a cricket match - 93,013 at the 2015 ODI World Cup final - is broken.
