Days-long extreme heat advisory issued for Indianapolis. NWS warns of triple digit heat wave
The summer solstice on June 20 welcomes the season with a breezy, sunny 86 degrees. That's temperate in comparison to the days to come: heat indices from June 21 to June 23 will spike as high as 102 degrees in Indianapolis.
A heat advisory has been issued for every day between June 21 and June 24. An extreme heat watch is in effect for parts of northern Indiana, including Logansport and Marion.
There will be "little overnight relief" from humidity, the NWS warns. The hot spell isn't expected to break until rainfall comes into the area, but that might not happen until late next week, according to NWS meteorologist Alexander McGinnis.
"As you get toward the end of the week, it's not quite as hot or quite as humid, but (the forecast shows) no significant improvement in the heat or humidity at this time," McGinnis said.
At 8 a.m. on June 20, AES reported that 13,000 customers remained without power after June 18 storms. Going without air conditioning during the extreme heat can be dangerous, and Indy Parks and public libraries will be open to those seeking relief from the heat.

Older Hoosiers and young children are at the greatest risk during extreme heat events. To stay safe and prepared, here's what the experts suggest:
The American Red Cross
The National Weather Service
Centers for Disease Control and Prevention
The three main heat-related illnesses to look out for are heat cramps, heat exhaustion and heat stroke. If any of the following symptoms are evident on you or another person: move to a cooler area, loosen clothing and sip cool water. Seek a medical professional if any of the symptoms don't improve within an hour.
Heat cramps may be the first sign of illness that could lead to more serious symptoms. Cramps show up as painful muscle cramps or spasms along with heavy sweating, according to NWS. Use firm pressure on the cramping muscles and massage them gently.
Heat exhaustion will show up as heavy sweating, weakness or tiredness with cool and clammy skin. The person's pulse may be quick but weak and they may exhibit dizziness or nausea. Immediately move the person to an air-conditioned room, loosen clothing and apply cool, wet cloth to the skin.
Heat stroke needs immediate medical attention, so call 9-1-1 or get the patient to a hospital. Heat stroke can appear as throbbing headaches, confusion, nausea, dizziness, body temperatures above 103 degrees. The patient's skin can also appear red with a lack of sweat. This is a serious illness and delays in medical care can be fatal.

Millions to Be Hit by Massive Waves Across Three States
Based on facts, either observed and verified firsthand by the reporter, or reported and verified from knowledgeable sources. Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content. Millions of people across at least three East Coast states can expect massive, life-threatening waves this week as Hurricane Erin passes by the U.S. Why It Matters As of the most recent update from the National Hurricane Center (NHC), Hurricane Erin is a strong Category 2 hurricane with maximum sustained wind speeds of 110 mph. Fluctuations in storm strength are possible over the next few days. Although Erin won't be making landfall in the U.S, the massive storm will pass close enough to the East Coast to spur 20-foot waves in some cases, prompting warnings across North Carolina, Massachusetts and New York. What to Know One of the most severe risks facing the U.S. as the hurricane passes by will be dangerous ocean conditions. AccuWeather reported that beaches extending into the ocean, such as North Carolina's Outer Banks; Cape Cod, Massachusetts; and Long Island, New York, will face the largest waves. A stock photo shows large waves in Long Island, New York. A stock photo shows large waves in Long Island, New York. WoodysPhotos/Getty National Weather Service (NWS) offices have already issued myriad warnings related to the storm, including high surf advisories. "Large, dangerous waves will likely inundate and destroy protective dune structures," said a high surf advisory issued by the NWS office in Morehead, North Carolina In addition to the dangerous waves, "extreme beach and coastal damage" is likely. "Actions will need to be taken to protect life and property. Very dangerous swimming and surfing conditions expected, as well as the wave action resulting in significant beach erosion," the North Carolina advisory said. Even watching the waves can be dangerous, and NWS meteorologist Casey Dail urged people to not get too close. "It's certainly going to get worse throughout the day today and really peaking tomorrow into Thursday," Dail told Newsweek. "We would advise people to not get too close." Dangerous waves have already begun. A high surf advisory is already in place for Boston, Massachusetts. The advisory will go into effect for North Carolina beginning at noon on Tuesday. In New York, the high surf advisory will go into effect from 6 a.m. Wednesday to 6 p.m. Thursday. In some areas, a storm surge watch also is in place. What People Are Saying NWS Morehead in a high surf advisory: "Everyone should remain out of the water due to extremely dangerous surf conditions." NWS New York in a high surf advisory: "Life-threatening swimming and surfing conditions and localized beach erosion. Life-threatening rip currents are likely for all people entering the surf zone. Anyone visiting the beaches should stay out of the surf. Rip currents can sweep even the best swimmers away from shore into deeper water." What Happens Next Beachgoers should stay out of the water while the dangerous waves are in effect. People in the impacted areas should monitor local weather guidance as the storm progresses.

Hurricane Erin forces Outer Banks vacationers to evacuate as monster storm nears North Carolina
Holly Andrzejewski hadn't yet welcomed her and her family's first guests to the Atlantic Inn on Hatteras Island when she had to start rescheduling them, as Hurricane Erin neared North Carolina's Outer Banks on Tuesday and threatened to whip up wild waves and tropical force winds. Although the monster storm is expected to stay offshore, evacuations were ordered on such barrier islands along the Carolina coast as Hatteras as authorities warned the storm could churn up dangerous rip currents and swamp roads with waves of 15 feet (4.6 meters). Andrzejewski and her husband purchased the bed-and-breakfast, known as the oldest inn on the island, less than a week ago. 5 Homes along the Atlantic Coast in Dare County, N.C., are seen on Aug. 18, 2025, ahead of expected impacts from Hurricane Erin. AP By Monday, they had brought in all the outdoor furniture and made sure their daughter and her boyfriend, who are the innkeepers, had generators, extra water, and flashlights as they stayed behind to keep an eye on the property. 'It's just one of those things where you know this is always a possibility, and it could happen, and you just make the best out of it. Otherwise, you wouldn't live at the beach,' said Andrzejewski, who will also remain on the island, at her home about a 15-minute drive away. Erin lashed part of the Caribbean with rain and wind on Monday. Forecasters are confident it will curl north and away from the eastern U.S., but tropical storm and surge watches were issued for much of the Outer Banks. Officials at Wrightsville Beach, near Wilmington, North Carolina, reported to the National Weather Service rescuing at least 60 swimmers from rip currents on Monday. By early Tuesday, Erin had lost some strength from previous days but was still a Category 3 hurricane with maximum sustained winds of 110 mph (175 kph), the National Hurricane Center in Miami said. 5 Forecasters are confident that Hurricane Erin will curve north and away from the eastern U.S., but tropical storm and surge watches were issued for much of the Outer Banks. AP It was about 665 miles (1,070 kilometers) southwest of Bermuda and 720 miles (1,155 kilometers) south-southeast of Cape Hatteras and was moving northwest at a slower 7 mph (11 kph). A tropical storm warning remained in effect for the Turks and Caicos Islands, where government services were suspended, some ports were closed, and residents were ordered to stay home. On North Carolina's Outer Banks, coastal flooding was expected to begin Tuesday and continue through Thursday. The evacuations on Hatteras Island and Ocracoke came at the height of tourist season on the thin stretch of low-lying barrier islands that jut into the Atlantic Ocean and are increasingly vulnerable to storm surges. 5 Signs restricting beach access were posted in Dare County, North Carolina, ahead of Hurricane Erin's impacts. AP A year ago, Hurricane Ernesto stayed hundreds of miles offshore yet still produced high surf and swells that caused coastal damage. This time, there are concerns that several days of heavy surf, high winds, and waves could wash out parts of the main highway. Some routes could be impassable for days. This is the first evacuation for Ocracoke since Hurricane Dorian in 2019 caused the most damage in the island's recorded history. 5 This image provided by the National Oceanic and Atmospheric Administration shows Hurricane Erin on Monday, Aug. 18, 2025. AP Tommy Hutcherson, who owns the community's only grocery store, said the island has mostly bounced back. He's optimistic this storm won't be as destructive. 'But you just never know. I felt the same way about Dorian, and we really got smacked,' he said. Scientists have linked the rapid intensification of hurricanes in the Atlantic to climate change. 5 The evacuations on Hatteras Island and Ocracoke (seen above) came at the height of tourist season, according to reports. AP Global warming is causing the atmosphere to hold more water vapor and is spiking ocean temperatures, and warmer waters give hurricanes fuel to unleash more rain and strengthen more quickly. Bermuda will experience the most severe threat Thursday evening, said Phil Rogers, director of the Bermuda Weather Service. By then, waters could swell up to 24 feet (7 meters). 'Surfers, swimmers, and boaters must resist the temptation to go out. The waters will be very dangerous and lives will be placed at risk,' acting Minister of National Security Jache Adams said.

What is Hurricane Erin projected path? NOAA storm tracker map, spaghetti models, weather radar
Beachgoing Indiana tourists should pay close attention to Hurricane Erin on Tuesday as large waves and rough surf are predicted to pound the Atlantic Coast from Central Florida to Canada. North Carolina is on high alert, as the popular vacation location of Dare County is under a state of emergency. The county's website reports a permanent population of about 37,000 — but the population balloons from June through August to about 225,000 to 300,000. Here's what you need to know from the NOAA's National Hurricane Center if you have East Coast travel plans: This forecast track shows the most likely path of the center of the storm. It does not illustrate the full width of the storm or its impacts, and the center of the storm is likely to travel outside the cone up to 33% of the time. Illustrations include an array of forecast tools and models, and not all are created equal. The hurricane center uses only the top four or five highest-performing models to help make its forecasts. Hurricane Erin live updates: Storm starts rough slog up US East Coast Dangerous conditions in the surf zone with large, breaking waves are forecast from East Central Florida to Canada's Atlantic Coast beginning Tuesday, National Hurricane Center Director Michael Brennan has warned. Brennan is pleading with U.S. residents to take Erin's potential coastal impacts seriously, even though the nation will be spared a direct landfall. Offshore wave heights could exceed 20 to 30 feet. High tides are also expected to bring higher-than-normal water levels further southward along the coast, the weather service has warned. "It's not going to be a safe environment to be in the ocean," Brennan said, adding that even when the weather may be pleasant on shore, dangerous and possibly life-threatening rip currents could be lurking in the water. Because of its slow movement, coastal areas of North Carolina are expected to feel the brunt of the ocean's impacts for several days, according to the weather service office in Newport/Morehead City. Mandatory evacuations were issued Aug. 18 for Hatteras Island and Ocracoke Island. At its closest point, Erin is forecast to be about 200 miles off Cape Hatteras. Erin's mean diameter at 11 p.m. on Aug. 18 was roughly 355 miles, but the storm was creating 10-foot seas across an area of the Atlantic Ocean roughly 645 miles in diameter, according to hurricane center data. Hurricane force winds extend outward up to 80 miles from the center, with the greatest distance on the eastern side of the storm. Further south along the North Carolina coast, emergency officials rescued at least 60 people caught in rip currents and heavy surf on Aug. 18 in Wrightsville Beach, prompting a "no swimming" advisory through Friday. Evacuations were underway along parts of North Carolina's Outer Banks, a big draw for vacationers every summer. With Hurricane Erin's expected storm surge and waves of over 10 feet, the National Weather Service was urging people to stay out of the ocean to avoid deadly surf conditions expected through at least Thursday. Officials in Dare County warned that roads, including the main exit route, could soon be overwhelmed by water. "Dare County remains under a State of Emergency and a Mandatory Evacuation order is in effect for Hatteras Island," the county posted on social media. "Please note that N.C. Hwy. 12 may be impassable by August 19 at 5 p.m." The hurricane center warned that storm surge could cause the water to rise 2 to 4 feet above dry ground along the Outer Banks as Erin pushes northward. In neighboring Hyde County, a mandatory evacuation order went into effect Tuesday for Ocracoke Island. In addition to Erin, the hurricane center said it is also keeping an eye on a tropical wave located over the eastern tropical Atlantic that is producing disorganized showers and thunderstorms. Following behind Erin is yet another tropical wave that's given a 60% chance of becoming a tropical storm over the next seven days, the hurricane center said. A third disturbance just moved off the West African coast, but it's expected to encounter hostile conditions that may limit its further development. Thunderstorms are possible at times across Central Indiana today and across southern portions of the area this evening, according to a NWS Hazardous Weather Outlook. Isolated severe storms with damaging winds are possible, mainly this afternoon. Hot and humid conditions continue this afternoon — especially over southern portions of Indiana, where heat indices will reach into the 100- to 105-degree range. Showers and thunderstorms are expected after 4 p.m. in Central Indiana with a high temperature near 91. The chance of precipitation is 60%. Later this evening, scattered showers and thunderstorms are expected before 8 p.m., with isolated showers between 8 and 9 p.m. Expect low temperatures near 69 this evening with a chance of precipitation at 30%. Delaying potentially lifesaving preparations could mean waiting until it's too late. "Get your disaster supplies while the shelves are still stocked, and get that insurance checkup early, as flood insurance requires a 30-day waiting period," the National Oceanic and Atmospheric Administration recommends.
