A powerful and unseasonal heatwave is gripping vast areas of the United States this week, bringing extreme temperatures more typical of mid-summer than the spring season.
Meteorologists are warning residents of the health risks associated with prolonged exposure to the high temperatures.
The heatwave has been particularly intense in the southern states, with temperatures in Houston and other parts of Texas surpassing 90 degrees Fahrenheit (32 degrees Celsius).
While such readings are not entirely unusual for May in the region, the persistence of the heat is what has raised concern. Experts note that such extended periods of high temperatures are typically not seen until June.
Cameron Self, a meteorologist with the National Weather Service in the Houston and Galveston area, observed that this week's weather is more reminiscent of August conditions than those expected in May.
In the northern states, particularly North Dakota, several cities have recorded all-time high temperatures over the past few days, some of which have broken records that had stood for over a century.
Although cooler air is expected to bring some relief to the northern part of the country, states such as Texas and those across the southeastern US are likely to continue facing intense heat into the following week.
Health authorities are urging people to limit outdoor activity, stay hydrated, and take precautions against heat-related illnesses as the unseasonal weather continues.
