Monday morning’s low was 95 degrees, the service said.<\/p>\n In South Florida, the Meteorological Service this Monday also warned<\/a> of high temperatures in the 90s, with the heat index expected to approach 105 to 110 degrees.

A native of Miami, Mr. Roque said he didn’t remember the heat being this bad.<\/p>\n He described it as a dry heat, “coming up from the ground.” To cope, he’s been drinking a gallon and a half of water every day, or “twice as much as normal,” to stay hydrated, he said.<\/p>\n For those who want to cool down, there will be little chance of doing so in the places most affected by the high temperatures, with daily minimum temperatures particularly high.<\/p>\n The heat can be especially devastating for people who already suffer from health problems.<\/p>\n In the Phoenix area, for example, 12 heat-related deaths have been reported this year through mid-June, and 40 more open cases where heat is being investigated as a factor, according to the county medical examiner of Maricopa. And in Texas, more than a dozen heat-related deaths have been reported in 2023, The Associated Press<\/a> has reported<\/p>\n In the coming days, temperatures will be warmer in the desert Southwest, where highs could reach 110 degrees, with lows only in the 80s and 90s.<\/p>\n To stay safe on extremely hot days, the Weather Service on Monday advised people to drink plenty of fluids, stay in cooler rooms, stay out of the sun and check on family members and neighbors, especially people adults who live alone.<\/p>\n
