What This Map Covers
Map viewport covers New Brunswick using recent NOAA GOES East and West Geostationary Lightning Mapper flashes. New Brunswick is the most inland-leaning of the Maritime provinces, forested through the middle and bounded by the Bay of Fundy and the Gulf of St. Lawrence. The viewport spans the whole province, including Moncton, Saint John, Fredericton. Thunderstorms here are a warm-season pattern, generally June 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.
Safety limit: absence of a marker never proves outdoor safety. Satellite detections can be delayed or missed, and storms move between refreshes.
