The National Weather Service (NWS) has issued extreme heat warnings for parts of Arizona between Saturday and Tuesday, along with areas of Southern California for Monday, and is urging millions of people in impacted regions to “avoid exposure to the sun” from 10 a.m. to 6 p.m. local time.
Why It Matters
Between 2004 and 2018, an average of 702 people died in the United States each year due to excess heat, according to data from the National Center for Health Statistics, with the NWS reiterating this week that it is the “deadliest weather phenomenon in the USA.”
According to the NWS, an extreme heat warning means that a period of very hot temperatures, even by local standards, will occur.
