West Coast and East Coast heat waves: More record highs possible

Unrelenting heat waves are still pounding the Northeast and Pacific Northwest.

Unrelenting heat waves are still pounding the Northeast and Pacific Northwest. Heat is a silent killer. On average, more people die from heat than any other severe weather, including tornadoes, hurricanes or flooding, according to the National Weather Service. In Seattle's King County, at least two people, both in their 60s, have died from the heat, The Seattle Times reported, citing the King County Medical Examiner's office. The dangerous heat also struck Canada. Since the heat wave began, British Columbia saw "a significant increase in deaths" -- about 100 more than usual -- and it's suspected that the weather was a contributing factor, the chief coroner for British Columbia, Lisa Lapointe, said in a statement Tuesday.
