What This Map Covers
Map viewport covers Saskatchewan using recent NOAA GOES East and West Geostationary Lightning Mapper flashes. Saskatchewan is open prairie in the south and boreal forest and lakes in the north, with little terrain to slow summer systems crossing the province. The viewport spans the whole province, including Saskatoon, Regina, Prince Albert. Thunderstorms here are a warm-season pattern, generally May through August.
GLM detects optical flashes from orbit. It does not classify every marker as a cloud-to-ground strike, replace Canadian weather radar, or predict where lightning will hit next. This is not an Environment and Climate Change Canada product and carries no warning status. GLM sits in geostationary orbit above the equator, so it sees Saskatchewan at an increasingly shallow angle going north. Measured against the live feed, detections stop at roughly 55.5°N — the part of Saskatchewan above that line is outside usable viewing geometry, not quiet.
Safety limit: absence of a marker never proves outdoor safety. Satellite detections can be delayed or missed, and storms move between refreshes.
