Data on this website (if you click through to 5 May 2022) shows regions where the RCM constellation has produced data. There are very small footprint scenes (shown below) over the Red River of the North, where flooding is ongoing (blog post 1; blog post 2). The Normalized Radar Cross Section (NRCS) imagery within those small footprints is shown sequentially, from south to north, above. The NRCS imagery gives very high-resolution snapshots of flooded regions. This NRCS image from 00:13:39 has the largest extent of flooding within it.

A single image that shows the 6 scenes, aligned from south to north, is available here. (Warning: It’s large)

Data were also available from earlier in May. Compare this RCM2 NRCS image from 00:29:27 on 3 May to this RCM3 NRCS image from 00:05:41 on 4 May to this RCM3 NRCS from 00:13:39 on May 5th. Flooding has expanded slightly over the two days.
