Worcestershire are on flood watch after the abandonment of their County Championship match with Nottinghamshire at rain-battered New Road.
Although the Environment Agency has not issued immediate alerts for Worcester, the weekend rain is certain to top up the local rivers.
Club officials anticipate at least a 48-hour wait before the Severn - which flows directly past New Road - reaches its peak level. The Severn has flooded the ground to devastating affect before, most recently in 2007.
The final day washout against Nottinghamshire ended the visitors' plans to set up a finish. With Neil Edwards on 49 not out, they closed 174 ahead on day three after making 88-2 in their second innings.
Nottinghamshire lead by 174 with eight second-innings wickets still standing heading into the final day against Worcestershire at New Road.
Worcestershire resumed on a cold third morning on 72-6 in their first innings, still needing another 22 to avoid the follow-on.
England Under 19 all-rounder Aneesh Kapil hit 41 to ease the Pears past that target before they were all out for 157, a deficit of 86.
Left-armer Harry Gurney, signed from Leicestershire during the winter, took three of the final four wickets to finish with 4-40, while his fellow seamer Andre Adams made Kapil his fourth lbw victim of the innings to complete figures of 5-62, the 28th five-wicket haul of his first-class career.
Notts opener Neil Edwards hit 49 not out to guide the visitors to 88-2 in their second innings when bad light ended play on a day featuring 63.3 overs.
Andre Adams claimed four wickets as Worcestershire's batsmen found it tough going in the 27.3 overs of play that were possible on day two at New Road.
Nottinghamshire's bowlers once again came to the aid of their batsmen, reducing the hosts to 72-6 - still 22 runs short of avoiding the follow-on - by the time bad light halted proceedings.
Heavy overnight rain had delayed the start until mid-afternoon, though when the action did get underway the Pears seemed to be making comfortable progress when they reached 35 without loss.
However, once Australian Michael Klinger (22) became Adams' first victim, caught at second slip by Samit Patel, the hosts collapsed in a heap.
Ben Phillips claimed the first of five lbw decisions to get rid of Vikram Solanki, while Adams - who finished the day with figures of 4-23 from 10.3 overs trapped captain Daryl Mitchell for 24.
Alexei Kervezee suffered his third duck in his last four innings and with Moeen Ali and Ben Scott also departing, the latter to Harry Gurney, Worcestershire finished Friday still 171 runs behind and in serious trouble.
Nottinghamshire failed to build on a solid start as they were bowled out for 243 by Worcestershire on the opening day at New Road.
An opening stand of 70 between Alex Hales (49) and Neil Edwards (23) suggested the visitors might finally fire with the bat after posting three sub-200 totals in LV= County Championship action this season.
However, the pair both fell straight after an early lunch, and from then on Nottinghamshire struggled to post another meaningful partnership.
James Taylor (38) put on 56 with skipper Chris Read, who made 34, until the two well-set batsmen were dismissed in six balls from England Under-19 international Aneesh Kapil.
Andre Adams (21) and Steve Mullaney (24) added some useful late-order runs before Richard Jones bagged the last three wickets, giving him 4-76 for the innings.
Alan Richardson finished up with incredible figures of 22-11-23-2 for Worcestershire, who survived five overs before the close to finish on five without loss.
