How often do tropical storms, hurricanes form in June? We look at NOAA's records to find out

The 2025 Atlantic hurricane season is predicted to be "above average" but when do the first tropical storms or hurricanes usually form?
It's enough to make Florida residents a little jumpy, especially after three hurricanes made landfall in the state in 2024.

It didn't help when an area of potential tropical development popped up on the National Hurricane Center's tropical outlook map June 2, the day after the official start of the 2025 season. By June 4, chances for tropical development dropped to zero, with the non-tropical low pressure area expected to form over South and North Carolina, instead of staying over water.

So as we wait for the next "disturbance" to appear, we took a look back through NOAA's records to see when the first named tropical storm and hurricane has formed over the past several years.
Looking at the big picture, follow advice from forecasters and emergency officials to prepare now. Tropical storms formed in June 11 times over the past 30 years, with another 11 developing in April or May.
The first hurricane wasn't far behind, with six forming in June and nine during the first two weeks of July.
A tropical storm is classified as a hurricane when maximum sustained winds reach 74 mph. A major hurricane is one that is Category 3 or higher, with maximum sustained winds of at least 111 mph.

Historically, named storms that develop in June pop up off the southeastern coast of the U.S. and the Gulf of America, according to data from NOAA and the National Weather Service.
By August, storms usually develop in the Atlantic or as they emerge as tropical waves off the coast of Africa.
The Atlantic hurricane season runs from June 1 through Nov. 30.
Ninety-seven percent of tropical cyclone activity occurs during this time period, NOAA said.
The Atlantic basin includes the northern Atlantic Ocean, Caribbean Sea and Gulf of America, as the Gulf of Mexico is now known in the U.S. per an order from President Trump. NOAA and the National Hurricane Center are now using Gulf of America on its maps and in advisories.
The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center.

National Hurricane Center monitoring system that could develop into season's first storm

More than three weeks into the 2025 Atlantic hurricane season, the National Hurricane Center is watching a system with a slim chance of developing into the season's first storm. Showers and thunderstorms associated with a low-pressure system about 450 miles east of Bermuda show the potential for becoming a short-lived tropical depression, the hurricane center said at 8 p.m. ET on June 22. Satellite images showed it has some signs of organization, which could briefly become a tropical depression over the next day or so, according to the center's forecast by Philippe Papin, a hurricane specialist. The forecast gives the system a 40% chance of becoming a depression over the next 48 hours. But by June 24, the system is expected to encounter less favorable conditions that would end its chances of becoming anything more than a depression. The system's forecast to continue moving northeastward at 5 to 10 mph over the open Central Atlantic and poses no threat to land. Long-range seasonal outlooks for the Atlantic hurricane season that started on June 1 call for a busier-than-normal season with more than a dozen named storms. Elsewhere, the long-range outlook from the Climate Prediction Center doesn't indicate any other storm development over the Atlantic hurricane basin, including the Caribbean, before July 8. The Eastern Pacific, which already has seen five named storms since its season began on May 15, remains active. The hurricane center gives a system a couple of hundred miles offshore of Central America a 70% chance of becoming a tropical depression later in the week of June 22, according to Papin's update. Even before it develops into anything further, the system is forecast to produce heavy rainfall over portions of Costa Rica and Nicaragua, then into El Salvador and Guatemala over the next few days. The most recent storm, Hurricane Erick, struck the southern coast of Mexico with 125 mph sustained winds, a Category 3 on the Saffir-Simpson Hurricane Wind Scale, and monstrous waves. Reuters reported the storm left a trail of damage, including sunken boats and flooding. Regardless of how many storms threaten in the Atlantic this summer, the hurricane center advises that it only takes one to ruin someone's year. The center's director, Michael Brennan, encourages people who live in hurricane-prone areas to be prepared in advance.

Northern Lights Could Be Visible Tonight From These States

The northern lights could be visible once again Sunday night from some northern states, according to the National Oceanic and Atmospheric Administration—although the auroral activity will be limited to only northern states. The aurora borealis could appear tonight for viewers in the continental United States, including in ... More Minnesota, North Dakota and Montana. Getty Images No geomagnetic storms or solar winds are expected to impact the Earth on Sunday night, but NOAA is forecasting a maximum Kp index of three out of nine—indicating the aurora borealis could still be visible. The aurora will potentially be visible in eight states along the Canadian border, including Montana, North Dakota, and Minnesota, as well as in most of Canada and Alaska. The forecast also indicates a slight chance for minor solar radiation and radio blackouts—but forecasters noted there were no radio blackouts over the past 24 hours. The best time to view the northern lights is between 10 p.m. and 2 a.m., according to NOAA. The agency also recommends viewers move as far away from sources of light pollution as possible. The aurora borealis is most visible the closer one moves towards the north pole, but trying to view the northern lights from the far north in June could be difficult due to the longer daylight hours around the summer solstice. What States Will The Northern Lights Be Visible From? Most of Alaska and North Dakota may be able to see the northern lights, according to NOAA, along with northern parts of Washington, Idaho, Montana, Minnesota, Wisconsin and Michigan. How Can I Photograph The Northern Lights? An expert writing for National Geographic recommends photographers use a wide-angle lens and a tripod to capture as much of the sky as possible. A low light-capable lens will also help better capture the night sky. Smartphone cameras are now powerful enough to capture the northern lights, the expert said, but it's still recommended that photographers use a tripod in order to hold the camera still long enough to capture the lights. In May 2024, Earth was impacted by a major space weather event, later named the Gannon Storm by astronomers, which was caused by coronal ejections from a massive sunspot cluster on the surface of the Sun. The storm caused major geomagnetic storm conditions on Earth, making the aurora borealis visible as far south as Florida.
