World Cup weather: What happens if T20 semi-final is washed out and who will be in final?

The T20 World Cup is turning out to be an absolute thriller, mainly due to unpredictable conditions and playing surfaces.

Not many expected this World Cup to be so competitive, but 'non-traditional' T20 pitches and spirited fight from less established sides have made the tournament and its format memorable, while also providing a template for healthy competition in future events.

USA and Scotland gave an excellent account of themselves, with the co-hosts storming into the Super Eight stage.

Afghanistan, too, showed they must be taken seriously as they thrashed two-format world champions Australia to throw Group 1 of the Super Eight wide open. They then held their nerve against Bangladesh to qualify for the semi-finals against all odds. They join India in the last four after Rohit Sharma's team continued their unbeaten run in the tournament, capping the Super Eight stage with a thumping win over the Aussies.

In the other group, South Africa and England qualified for the semi-finals, with the Proteas continuing an unprecedented unbeaten run in the tournament to grab the top spot.

Jos Buttler's defending champions had an indifferent start to the tournament but have raised their game at important junctures to reach the business end.

But as the tournament gears up for a final flourish, one factor continues to cast a shadow over the remaining teams and the tournament: the weather.

It is rainy season across the Caribbean and hosting matches during this time of the year was always fraught with danger. So what happens if weather plays spoilsport this week?

The last-four clashes will take place at the Brian Lara Stadium, Tarouba, Trinidad, and Providence Stadium, Guyana, Wednesday overnight and Thursday.
