The arch-rivals were unable to train at the Glasgow ground on Monday because of a saturated outfield and intermittent rain.
"We are just hoping that there is not enough rain over the next 12-14 hours to get the ground any wetter because it has rained so much over the last six weeks in Scotland," Smith told reportes on Monday.
"For the last four or five days it has rained every day so, although we are remaining hopeful of getting play, the ground can't take a lot more rain."
Smith said he was happy about security arrangements for the match, after members of a suspected al Qaeda cell rammed a fuel-packed jeep into a terminal building at Glasgow Airport on Saturday.
"We are very comfortable with the security," Smith said. "Security was always going to be tight and will be tomorrow, but it's about having to react to situations that are faced by us.
"The police have been involved for five months in terms of planning the event. Everyone wants the event to go ahead smoothly and I'm sure we can control every situation, apart from the weather."
India, Pak geared up for big one: The one-off tie is to raise funds for Prince Charles' charity but there would no lack of edge that goes with any Indo-Pak clash. If anything, the teams go into the match with a lot riding on the outcome than ever before. Having suffered ignominious first round exits at the quadrennial event, both India and Pakistan are experiencing a revival of sorts.
Pakistan, led by 25-year-old Shoaib Malik who succeeded Inzamam-ul-Haq, crushed Sri Lanka 2-0 in Abu Dhabi in May. India had a successful tour of Bangladesh, winning both the ODIs and Tests comfortably. And they have the momentum going into the match after a 2-1 series win over South Africa in Ireland.
Both the teams without full-time coach have fared better in the recent past. Pakistan would have their bowling attack strengthened with the return of mercurial speedster Shoaib Akhtar who has not played a match after a positive dope test before the Champions Trophy in India last October-November.
Also returning to the squad are top order batsman Younis Khan and all-rounder Abdur Razzaq.
Yet, the advantage might be with the Indians who have the match form and winning momentum from the Ireland series. The batsmen have been among runs and especially gladdening the fans hearts has been the form of Sachin Tendulkar who cracked two 90-plus knocks against the South Africans.
