Heatwaves have killed more folks on average than any other excessive climate event within the US, according to the Centers for Disease Control (CDC).
Officials outline extreme heat as a period of 2 to 3 days of high heat and humidity with temperatures above 90F (32C).
On the heels of earth’s hottest June on record, the US National Weather Service (NWS) estimates over 100 record-high minimum temperatures might be set as the heat lingers even past sunset.
Here is what heat can do.
Air-conditioning is utilized in 87% of US homes, in keeping with a 2018 report by the US Energy Data Administration (EIA). During heat waves, air conditioning use stresses power grids and may result in city-wide outages.
In cities, it means hundreds of thousands of units – together with those on automobiles and buses and trains – constantly pushing out heat into the atmosphere. Research have discovered the extra heat from air-conditioning can raise temperatures by as a lot as 2C. And when it gets hotter, our thermostats turn lower, and the cycle continues.
When temperatures get too high, planes get grounded.
Extreme heat reduces air density, and the amount of lift an airplane can get to take-off. Temperatures of 120F (49C) saw dozens of flights canceled in Phoenix throughout a 2017 heatwave.
Smaller planes are affected first. However bigger Boeing or Airbus jets have maximum operating temperatures around 126F (52C), AZ Central reported.
In a heatwave, concrete and asphalt do not farewell.
Asphalt warps and melts. Concrete, if the water is involved, can typically explode or break open.
This week, local media in Kansas has reported several instances of cracked and buckled roads as temperatures rise.
In Iowa, one city mayor mentioned old concrete roads soaked with floodwaters from this spring are exploding and damaging sewer lines.
