A plain that was a lake
This story runs on climate-shift, on the US and Canadian river gauges, and on satellite layers prepared for this page in Earth Engine.
Exploratory: generated automatically from the UmaTerra platforms' data; not independently validated or peer reviewed.
Between 13 and 15 November 2021 an atmospheric river poured two days of rain onto southern British Columbia. Rivers broke their banks on both sides of the border, and Sumas Prairie, a farm plain built on the bed of a lake drained a century ago, filled with water again. Clouds hid the valley, so this story reads the flood with radar, follows the rivers at their gauges, and reads the climate ahead and La Niña in climate-shift.

NASA's IMERG estimates the rain every half hour from a constellation of satellites; here it is summed every three hours.
