Sri Lanka has been hit by monsoon downpours since December hampering preparation of the pitches at the newly-built Pallekele venue in the island's central district.

Pallekele was to host practice matches between Sri Lanka and the Netherlands on Saturday and Kenya and the Netherlands on Tuesday. A new venue for the two matches will be announced shortly, the organisers said in a statement.

"The ground staff at Pallekele have had to contend with an extremely high volume of rainfall over a number of weeks, far in excess of what is normal for this time of year," tournament director Ratnakar Shetty said.

"This has proved to be a significant handicap in their efforts to produce pitches for the forthcoming warm-up matches," he said.

Shetty said the decision to move the warm-up matches would give ground staff time to prepare "excellent pitches" for the tournament.

The decision to shift the games will not affect World Cup matches, the ICC said.

Pallekele will be the venue for three World Cup matches, the first between New Zealand and Pakistan is scheduled for March 8.

The showpiece event, being co-hosted by Sri Lanka, India and Bangladesh, starts on February 19.

Heavy monsoon floods across Sri Lanka's central, northern and eastern regions have claimed at least 21 lives and affected over 1.2 million people.
