A cold front moving through the Midwest will reach the East Coast by Monday, bringing heavy rain and cooler air, according to CNN Meteorologist Ivan Cabrera.
The front will quiet days of extreme temperatures, Cabrera said.
Part of the relief comes from the dropping of overnight temperatures in the Midwest, which had often hovered near 80 degrees in the past week.
While temperatures on the East Coast and Midwest may sink down to the 70s on Monday, Sunday was still hot.
Sunday severe weather
Although down from Saturday’s 157 million, there were still more than 95 million people under a heat warning or advisory for Sunday.
In New York, utility company Con Edison asked customers to save energy as outages rose throughout the day Sunday. By 6 p.m., about 13,000 of its customers were without power, up from almost 11,000 an hour earlier, according to Con Edison’s outage map.
Staying safe in the final stretch
With one day of extraordinary heat left, officials are still asking people to take steps to stay safe.
Over the past week, the heat wave stretched from New Mexico to Maine, prompting authorities across the country to put out warnings and recommendations to help deal with the heat.
While many people — especially in regions that tend to see higher temperatures regularly — underestimate the dangers of summer heat, it annually kills more Americans on average than any other natural disaster, Cabrera said.
Those most vulnerable include the elderly, infants, children, those in cities and people who live or work outside, according to a report by the International Federation of Red Cross and Red Crescent Societies.
To reduce those dangers, the report and city officials recommend staying hydrated, avoiding being outside during peak heat hours, training medical staff and community members on heat stroke symptoms and enlisting the help of friends, family and neighbors to check on people particularly at risk.
Climate change’s impact
The threat of heat waves will become more serious across the globe and more widespread as the climate crisis continues, says Francesco Rocca, president of the International Federation of Red Cross and Red Crescent Societies.
“Climate projections indicate that if greenhouse gas emissions continue on their current pathway, by the year 2100 three out of four people on Earth could be subject to at least 20 days per year of potentially deadly heat and humidity levels,” the report says.
