Technically summer starts next week, and it will show America what the world is capable of Global warming due to fossil fuel pollution And Without El Niño.

Long-term, record-breaking heat is heading to a part of the country that has so far been largely avoided, with wildfire risks rising in the West and bathtub-warm waters fueling the first tropical depression of the Atlantic hurricane season.

The heat came It’s Friday in the eastern part of the country, but that’s an appetite for what’s to come.

Creates an extensive and exceptionally strong thermal dome It will expand in the east on Sunday and reach the Midwest and Great Lakes in the following days, causing the first significant heat wave of the year. Thermal domes trap air in place and bake for days with more sunlight, making each day warmer than the last.

It can send temperatures skyrocketing beyond a typical hot summer day.

Both day and night temperatures could drop hundreds of records by the end of next week.

Temperatures will be 15 to 20 degrees above normal over much of the eastern part of the country on Monday afternoon.

It replaces days of high temperatures in the 90s for tens of thousands of people who don’t bake in prolonged heat.

No relief from heat at night, another sign of a warming world. Overnight low temperatures are not expected to drop into the low 70s or lower 60s in many places.

To make matters worse, humidity combined with intense heat can send the heat index — how hot the human body feels — into the dangerous triple digits in eastern parts. Heat index values ​​in the low 100s are possible as far north as Maine next week.

Health risks from the heat could reach extreme levels for millions next week, according to the National Weather Service and CDC. Heat is Deadly form of weather In the United States, hurricanes and tornadoes combined kill twice as many people each year on average.

Atlantic hurricane season is poised to wake up, while sweltering summer heat is scorching a significant portion of the country.

There are two short-term risk areas that could produce the first tropical system of the year, and both are conveniently close to the US coast.

An area in the southwestern Gulf of Mexico has a high chance of becoming a tropical system. A small window and the same storm pattern that could develop into a tropical depression off the Southeast coast before Florida’s rain washes out to sea later this week.

A strong tropical moisture gyre in the Gulf Southwest is caused by the Central American Gyre: a large, irregular area of ​​rain and thunderstorms that swirls over the waters of Central America and the surrounding area.

The gyre’s wide gyre and abundant moisture will help produce tropical systems in the Caribbean, Gulf of Mexico, and parts of the extreme eastern Pacific Ocean as other necessary factors — including favorable upper-level winds and warm ocean waters — align.

That may be the case in the middle of the week; A tropical depression is likely to develop in the Gulf of Campeche in the southwestern Gulf, the National Hurricane Center said. Much of the Gulf of Mexico is bathtub-warm, so if a tropical system forms, there will be plenty of fuel to fuel it. If something forms, it is likely to track north or northwest.

An upwelling similar to the rear of moisture, regardless of tropical development Flooding in South Florida It will provide much-needed wet weather to parts of Mexico Baking under extreme heat and weeks of severe drought.

But it will increase the risk of flooding, especially in areas along the Gulf Coast Soaked in this spring.

Several days of rain are headed toward the Gulf Coast from Texas to Alabama throughout the week starting Sunday.

The heat doesn’t just make us sweat and fuel hurricane season — it’s also had a hand in several recent notable wildfires.

Reports suggest that fire activities are gradually increasing across the country National Interactive Firefighting Center. Nearly a dozen large fires are burning in parts of the West and about half of these have started in recent days.

Hot, dry conditions in place From the beginning of the month Wildfire risk will continue to increase in the West and continue to worsen. During this time wildfire fuels such as grass and plant life continue to dry out, making them more prone to fire ignition or spread.

The area will be windy this weekend and early next week. Forest fires spread rapidly due to strong winds Coral fire Demonstration in California in early June.

Windy conditions will fuel a small but destructive fire next week, known as the Rose Fire, about 70 miles northwest of Phoenix.

The fire destroyed at least 15 structures — seven of them homes — along with at least a dozen vehicles, the Arizona Department of Forestry and Fire Management said Thursday.
