As the US braces for a summer filled with extremes, the nation is facing disastrous weather patterns in both the north and south of the country. In the northeast, heavy flooding has caused the tragic deaths of at least five people, with two more missing. In the southwest and southeastern states, millions of people are under warning and forecasts of extremely high temperatures and heat waves.

The Upper Makefield Township in Pennsylvania has been particularly hard hit by the weekend’s storm, where authorities report that a nine-month-old baby and a two-year-old girl are still missing. Between 127 and 177.8 millimeters of rain fell in North Philadelphia in less than 45 minutes, according to local news reports.

The National Wather Service is warning of a “heatwave with sweltering temperatures that will continue into next week.” Temperatures up to 46 degrees are expected in Nevada and Arizona. As of today, more than 80 million people are at risk of heat-related illnesses and other dangerous effects of high temperatures.

With no hints of rain in the forecast, the US is facing a long and dangerous summer as severe weather ravages the country. Emergency crews are working around the clock in the states deemed hardest hit, yet officials are concerned that the damage may only worsen as temperatures continue to rise. As a result, local governments are advising caution and support for those in need as the US weathers the storm.
