Extreme heat alerts issued across multiple US states
This weather pattern, characterized by extreme heat, was expected to persist well into the coming week, with warnings and advisories being issued across various states.
The National Weather Service reported that nearly the entire northeastern region, from Minnesota to Maine, was under some form of heat advisory, affecting states like Arkansas, Tennessee, Louisiana, and Mississippi.
Meteorologists attributed the record-breaking temperatures to a phenomenon known as a heat dome. This occurs when a large area of high pressure in the upper atmosphere traps heat and humidity close to the ground, resulting in oppressive weather conditions.
Throughout the region, local weather service offices urged residents to plan accordingly, advising them to take frequent breaks if they had to be outdoors, stay hydrated, and ensure that pets had access to water and shade.
Thunderstorm in New York
Adding to the weekend's turmoil, severe thunderstorms rocked parts of New York, leading to tragic outcomes. On June 22, three people, including twin six-year-old girls, lost their lives when a storm brought down trees onto homes in the central part of the state.
In the aftermath, the Oneida County Sheriff's Office confirmed that several inches of rain fell in just a few hours, inundating areas like Kirkland and leaving many without power. New York Governor Kathy Hochul declared a state of emergency in 32 counties due to the severe storms and ongoing heat crisis.
By June 22, heat advisories had been in effect for days, with temperatures reaching staggering highs. In cities like Chicago, the heat index soared to 103°F (39.4°C), and Madison, Wisconsin, reported highs of 101°F (38.3°C).
Many residents sought refuge indoors, with some remarks highlighting the challenges of outdoor activities. Lynn Watkins, director of a local day care, expressed her struggle, saying it was simply too hot to enjoy grilling outdoors.
In Pittsburgh, the heat index hit 105°F, prompting local health officials to declare a heat emergency for the area. They encouraged citizens to take advantage of air-conditioned public spaces while providing access to a hotline staffed by medical professionals to address heat-related illnesses.
As the oppressive heat continued, beachgoers flocked to Rehoboth Beach in Delaware, where temperatures hovered in the mid-80s. Expecting sustained heat, residents prepared for increasingly challenging conditions.
Fans at the PGA Travelers Championship in Cromwell, Connecticut, were seen seeking shelter from the heat, showcasing the struggle to remain comfortable during one of the hottest stretches of weather in recent memory.
As the week progresses, forecasters warned that the extreme temperatures would shift further east, with cities like New York and Boston anticipating highs around 95°F and 100°F, respectively. The heat wave, culminating in significant discomfort for millions, serves as a stark reminder of the impact of extreme weather conditions.
Mark Gehring, a meteorologist with the National Weather Service in Sullivan, Wisconsin, said such heat is typical for U.S. summers, though it usually peaks in mid-July or early August. What makes this heat wave unusual, he noted, is the vast area it's affecting.
"It's basically everywhere east of the Rockies," he said, referring to the Rocky Mountains. "That is unusual, to have this massive area of high dewpoints and heat."

Parts of Juneau prepared for flooding from water slipping past Alaska's Mendenhall Glacier
Sections of Alaska's capital city are bracing for the arrival of what could be record floodwaters due to rainwater and snowmelt flowing downstream from a basin dammed by the Mendenhall Glacier. Some Juneau residents in the flood zone have evacuated, heeding warnings. On Tuesday morning, authorities confirmed water had started escaping the ice dam, with flooding expected into Wednesday. The Mendenhall Glacier is about 12 miles (19 kilometers) from Juneau, home to 30,000 people, and is a popular tourist attraction due to its proximity to Alaska's capital city and easy access on walking trails. Homes on the city's outskirts are within miles of Mendenhall Lake, which sits below the glacier, and many front the Mendenhall River, into which the glacial outburst is flowing. The National Weather Service said it expected flooding to to peak around 8 a.m. to noon on Wednesday. 'This will be a new record, based on all of the information that we have,' Nicole Ferrin, a weather service meteorologist, told a news conference Tuesday. Basin flooding is a yearly worry Flooding from the basin has become an annual concern since 2011, and in recent years has swept away houses and swamped hundreds of homes. Government agencies installed temporary barriers this year in hopes of protecting several hundred homes in the inundation area from widespread damage. The flooding happens because a smaller glacier near Mendenhall Glacier retreated — a casualty of the warming climate — and left a basin that fills with rainwater and snowmelt each spring and summer. When the water creates enough pressure, it forces its way under or around the ice dam created by the Mendenhall Glacier, enters Mendenhall Lake and eventually flows down the Mendenhall River, as it did Tuesday. Before the basin began overtopping, the water level was rising rapidly — as much as 4 feet (1.22 meters) per day during especially sunny or rainy days, according to the National Weather Service. The city saw successive years of record flooding in 2023 and 2024 — with the river last August cresting at 15.99 feet (4.9 meters), about 1 foot (30 centimeters) over the prior record set a year earlier — and flooding extending farther into the Mendenhall Valley. This year's flooding was predicted to crest at between 16.3 and 16.8 feet (4.96 to 5.12 meters). Last year, nearly 300 residences were damaged. A large outburst can release some 15 billion gallons of water, according to the University of Alaska Southeast and Alaska Climate Adaptation Science Center. That's the equivalent of nearly 23,000 Olympic-size swimming pools. During last year's flood, the flow rate in the rushing Mendenhall River was about half that of Niagara Falls, the researchers say. A temporary levee is installed City officials responded to concerns from property owners this year by working with state, federal and tribal entities to install a temporary levee along roughly 2.5 miles (4 kilometers) of riverbank in an attempt to guard against widespread flooding. The 10,000 'Hesco' barriers are essentially giant sandbags intended to protect more than 460 properties completely during an 18-foot (5.5-meter) flood event, said emergency manager Ryan O'Shaughnessy. The US Army Corps of Engineers is at the start of what's expected to be a yearslong process of studying conditions in the region and examining options for a more permanent solution, such as a levee. The timeline has angered some residents, who say it's unreasonable. Outburst floods are expected to continue as long as the Mendenhall Glacier acts as an ice dam to seal off the basin, which could span another 25 to 60 years, according to the university and science center researchers.

Alaska city faces ‘record' flooding from water escaping glacier dam
A huge basin of rainwater and snowmelt dammed by Alaska's Mendenhall Glacier has started to release, and officials on Tuesday urged residents in some parts of Juneau to evacuate ahead of what could be a record surge of floodwater downstream. Officials in recent days have been warning people in the flood zone to be ready to evacuate. On Tuesday morning they confirmed water had started escaping the ice dam and flowing downstream, with flooding expected late Tuesday into Wednesday. Flooding from the basin has become an annual concern, and in recent years has swept away houses and swamped hundreds of homes. Government agencies installed a temporary levy this year in hopes of guarding against widespread damage. 'This will be a new record, based on all of the information that we have,' Nicole Ferrin, a National Weather Service meteorologist, told a news conference Tuesday. Story continues below advertisement The Mendenhall Glacier — a thinning, retreating glacier that is a major tourist attraction in southeast Alaska — acts as a dam for Suicide Basin, which fills each spring and summer with rainwater and snowmelt. The basin itself was left behind when a smaller glacier nearby retreated. When the water in the basin builds up enough pressure, it forces its way under or around the ice dam, entering Mendenhall Lake and eventually the Mendenhall River. Before the basin reached the limit of its capacity and began overtopping over the weekend, the water level was rising rapidly — as much as 4 feet (1.22 meters) per day during especially sunny or rainy days, according to the National Weather Service.
