New York, July 20 (RHC)-- An unrelenting heat wave across the southern United States is continuing today, with dozens of temperature records set to fall.  

In Phoenix, Arizona, where nighttime temperatures haven’t fallen below 90 degrees Fahrenheit since early July, forecasters are predicting a 20th consecutive day with high temperatures over 110 degrees. 

This week, more than 44 million people in 28 U.S. states and several Canadian provinces have been affected by smoke from a record number of wildfires.

In related news, in northern Mexico, migrants stuck at the U.S. border waiting to apply for asylum are facing increasingly desperate conditions.  Temperatures in the border city of Nuevo Laredo soared to nearly 110 degrees on Wednesday.

One migrant, Carmen Sarmiento, who agreed to speak with journalists said: “We need to be drinking cold beverages frequently to adjust our body temperature.  But the rest of the day we feel low in energy, dehydrated.  My daughter’s lips are chapped even though I give her hydration solutions and lip balm.  She’s still quite affected.”
