Russian forces have made repeated but limited infiltration attempts into Prymorske and nearby areas along the dried Kakhovka Reservoir bed south of Zaporizhzhia City, exploiting seasonal conditions such as dense vegetation, humidity, and fog that hinder Ukrainian reconnaissance. Ukrainian units regained full control after earlier Russian entries and maintain positions in northern Plavni and along the M-18 highway, restricting Russian resupply to small infantry groups. Recent reports note a Russian infiltration near Malokaterynivka around September 19, 2026, alongside ongoing operations in the broader Zaporizhzhia and Hulyaipole directions where neither side has recorded major territorial shifts. Trader assessments of a capture by any near-term deadline hinge on whether autumn-winter weather enables sustained Russian advances or Ukrainian defenses and counter-infiltration measures hold the line.
