In the Great Lakes region on Tuesday, highs will be 15 to 25 degrees above normal, and California will see triple-digit thermometers from Fresno in the San Joaquin Valley to Redding in the north.

Over the next few days, the center of the heat will shift south and southeast from Texas to Georgia, with many cities expected to experience triple-digit temperatures, including Dallas, Houston, New Orleans, Memphis, Nashville and Atlanta.

More than 70% of the US population will see a high above 90 degrees over the next seven days, and 20% will see highs above 100 degrees.

More than 100 daily high temperature records could be set between Tuesday and Saturday, mostly across the East and South. Overnight temperatures shouldn’t offer much respite as more than 80 hot low temperature records could be broken this week.

Tuesday's three-day weather forecast as a heat wave hits the United States.
This is after a massive heat dome across the eastern US and the Midwest created record high temperatures in several cities last week – and intensified the misery of some communities already battling power outages. following a series of violent storms.

Extreme heat conditions can be detrimental to a person’s health, especially for the elderly, children, and people with chronic illnesses or mental health issues.

The heat wave is the “Super Bowl” of energy consumption for electric companies

Earlier this year, US electricity regulator NERC warned that extreme temperatures and other environmental factors could cause power grid outages across large areas of the country this summer.

In anticipation, power companies across the Southeast say they are bracing for the added strain that will come as masses of heat-stricken people retreat indoors to relieve air conditioning.

“This is our ‘Super Bowl’ that we’ve been preparing for all year,” Tennessee Valley Authority (TVA) spokesman Scott Fiedler said in a statement to CNN. “TVA is extremely well positioned to meet electricity demand during the hot weather this week. As you know, temperature and load go hand in hand, so we should see high loads the rest of this week.”

Energy experts are sounding the alarm about the US power grid:

Electricity demand last week was record high for TVA, which saw more than 31,000 megawatts used on Thursday, just days after surpassing the 31,000 megawatt mark on June 13, Fiedler said.

Georgia Power and Duke Energy Carolinas, which serve the North Carolina and South Carolina markets, said they are ready for the increased demand that scorching temperatures will bring.

Duke Energy Carolinas recorded record summer use of 21,000 megawatt hours of electricity on June 13, eclipsing its previous summer record set in July 2016, the company said in a statement.

Duke Energy Process, the company’s other Carolina utility, didn’t break any records, but the two companies combined saw a peak usage record of 34,079 megawatt hours, beating the old record set in July 2020. , according to the press release.

How to stay cool without air conditioning

Entergy, which serves parts of Arkansas, Louisiana, Mississippi, New Orleans and Texas, said the company expects to see unprecedented levels of power consumption this week.

“We have a detailed plan for extremely hot weather, which includes our power plants and transmission operators taking steps to maintain the balance of supply and demand on the grid and actions to reduce the risk of tripping. generation or transmission facilities,” the Entergy newspaper said. statement said.
