Agree with Brian, we had a freak number of incidents involving thunderstorms a few seasons back (when I wasn't even a glint in my mentor's eye) and they said don't bother with counting anything, just stay extra-focused on the game and you will notice if it is affecting the game so much as to suspend play. Straight to changing rooms - be careful with any history from what you have already played. A good 10 minutes and check again. A good trick pointed out to make the rest of the game easier, if the facilities allow get everyone in the one room/area together and address them at the same time, the experience of everyone sitting and getting warm again together, gives the impression everyone is in it together against the weather, dissent, petty handbags incidents and the like almost non-existent in the remainder of the game. Of course use common sense - if the game is less than savoury be sure to segregate the teams.
