Rain is washing away Tasmania's hopes of a Sheffield Shield victory over NSW, with the first session of the final day completely written off in Hobart.
After the Tigers went to stumps on day three with a 293-run lead in their second innings and with eight wickets in hand, no play was possible in the opening hours of day four.
If play finally does resume, Tasmania opener Tim Ward will have a chance at his first century of the summer after going to stumps unbeaten on 90 off 71 balls.
After NSW declared their first innings at 7-216 - still 117 runs behind - in a bid to pursue an unlikely result, Ward's aggressive start gave the Tigers a shot at an early declaration of their own on day four.
Caleb Jewell struck 34 off 25 and Matthew Wade 41 from 34, but Hobart's wet weather could mean those efforts amount to very little on Tuesday.
Tasmania are pursuing their second victory of the season, while the Blues risk going winless through their first four games for the first time since 2011-12.
