After the heat dome hovered over British Columbia and the Northwestern United States for a few days, it began to move eastward, breaking records east of the Rocky Mountains, particularly in the northern parts of the Prairie provinces, but bringing relief to the Pacific coast.[30][31] At this stage, the heat is kept between the warm and cold fronts of the low-pressure area that has formed over southern Northwest Territories, and transported eastward towards Hudson Bay.[32] Sweltering conditions are expected in the coming days as far east as Montana,[33] Manitoba,[34] and in extreme Northwest Ontario,[35] though the temperatures are not expected to be as high.[36][37]
