Frequent rainfall, thunderstorms and severe weather continued to shape crop development across Manitoba over the past week, with many areas receiving additional moisture on top of already saturated conditions, according to the latest provincial crop report on Tuesday.
Rainfall was highly variable, with weekly accumulations ranging from 9 mm at Sprague to 188 mm near Boissevain. The heaviest totals were reported in the Southwest around Boissevain and Souris, and in already waterlogged parts of the Northwest, including San Clara, Ethelbert, Dauphin, Minnedosa and Russell. Hail, strong winds, intense rain and possible tornadoes were reported across much of the province, while a tornado was confirmed in Winnipeg’s Whyte Ridge neighbourhood on June 29.
The continued wet pattern has pushed seasonal rainfall above normal across much of Manitoba. Since May 1, the Northwest and Interlake have accumulated around 220 mm of precipitation, with parts of the Northwest receiving more than 200% of normal. Portions of the Central and Southwest regions are also above normal following recent rainfall, although some localized areas in the Central and Eastern regions remain below 80% of average.
Despite the wet conditions, crops continue to advance. Winter wheat and fall rye are flowering and generally show strong yield potential, with many fungicide applications already complete. Spring cereals are mostly between tillering and stem elongation, with the earliest fields reaching early heading. Growers are shifting attention to fusarium head blight risk, while suspected tan spot and other cereal disease symptoms are being monitored.
