1800 IST - Nothing much has changed in the last half-an-hour. The rain is still falling heavily, though it has just relented a bit and the skies have cleared up a touch. But, there is lightning in the sky. We are already past the extra allotted time for a day-night game, meaning that it will be a curtailed match. 2119 IST is the cut-off time for the second innings to start. Stay tuned for updates.
However, with the previous commentary piece advising there's 'lakes' all over the ground in Columbo, I can't see this game restarting to be honest.
