National Hurricane Center Tracks New Disturbance in Atlantic: What to Know
Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content.
A new disturbance has formed in the central tropical Atlantic, the National Hurricane Center (NHC) in Miami reported on Sunday.
The system, known as a tropical wave, is located about 1,000 miles east-southeast of the Lesser Antilles in the Caribbean Sea. It's already producing disorganized showers and thunderstorms as it moves west-northwestward at approximately 10 to 15 miles per hour.
As of the NHC's latest forecast, environmental conditions appeared only marginally favorable for further development in the short term, with prospects falling to unlikely by midweek.
Newsweek has reached out to the NHC for further comment via email Sunday during non-working hours.
Why It Matters
While the current disturbance is expected to dissipate before posing a direct threat to land, tracking these systems gives meteorologists and emergency managers time to plan should conditions shift unexpectedly.
They are also valuable to residents and governments as they ready their emergency preparedness resources and emergency notification systems.
Storm preparedness and recovery has been of national concern following the floods in Texas that killed over 100 people and subsequent flash flooding across the U.S. amid funding cuts to the Federal Emergency Management Agency (FEMA).
What To Know
According to the NHC, the disturbance is identifiable as a tropical wave carrying clusters of disorganized showers and thunderstorms in the open Atlantic.
A tropical wave is defined by the NHC as "an inverted trough (an elongated area of relatively low pressure) or cyclonic curvature maximum moving east to west across the tropics."
These systems "can lead to the formation of a tropical cyclone. Also known as an easterly wave," the NHC cautions.
The system is being steered west-northwest by prevailing atmospheric conditions.
However, due to increasing wind shear and the potential intrusion of Saharan dust, the likelihood of the system organizing into a tropical depression or storm is currently considered low.
The forecast in the NHC's 7-Day Graphical Tropical Weather Outlook, shows the wave track continuing over open water, with no watches or warnings currently in effect for any land areas.
The 2025 Atlantic hurricane season, which started June 1, has already seen three named storms: Andrea, Barry and Chantal.

What People Are Saying
Richard Pasch, senior hurricane specialist for the NHC, said in a statement Sunday: "Environmental conditions appear only marginally conducive for development during the next day or so while the system moves west-northwestward at 10 to 15 mph. By the middle of the week, environmental conditions are forecast to become unfavorable for further development."
NHC Deputy Director Jamie Rhome told The Daytona Beach News Journal: "If a system is near land and there is potential for development, the National Hurricane Center won't wait before it issues advisories, even if the system hasn't become an actual storm. This gives residents time to prepare."
What Happens Next?
The NHC and partnering meteorological agencies will continue to monitor the progress of this tropical wave.
Updates and outlooks are issued several times daily on the NHC's official website.

Storm tracker: Disturbance east of Caribbean expected to weaken, forecasters say
The National Hurricane Center is monitoring a disorganized group of showers and thunderstorms east of the Caribbean, with odds of it forming into a tropical cyclone slightly decreasing on Monday, July 21. As of the center's July 21 midday report, there are showers and thunderstorms associated with an area of low pressure hundreds of miles east-southeast of the Lesser Antilles, with a 10% chance it will form into a tropical cyclone in the next 48 hours. The disturbance was set to move west at about 15 miles per hour, forecasters said, but conditions are expected to prevent further formation in the coming days. Chances of it strengthening into a cyclone within the next week are similarly low, forecasters say, also at about 10%. "Although the wave is still producing disorganized showers and thunderstorms, environmental conditions are not expected to be conducive for development during the next few days," the July 21 update said. The Atlantic hurricane season officially began on June 1 and will last through the end of November. Active hurricane weather typically peaks between mid-August and mid-October. Atlantic hurricane season storm tracker How do hurricanes form? Hurricanes are born in the tropics, above warm water. Clusters of thunderstorms can develop over the ocean when water temperatures exceed 80 degrees Fahrenheit. If conditions are right, the clusters swirl into a storm known as a tropical wave or tropical depression. A tropical depression becomes a named tropical storm once its sustained wind speeds reaches 39 miles per hour. When its winds reach 74 mph, the storm officially becomes a hurricane. Prepare now for hurricanes Delaying potentially life-saving 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," NOAA recommends.

Hundreds of Thousands of People Warned to 'Stay Out of the Water'
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. More than 200,000 beachgoers and swimmers along the coast of Lake Ontario in New York were told to stay out of the water on Monday morning amid dangerous lake conditions. Why It Matters The Great Lakes, including Lake Ontario near Buffalo, are premier recreation destinations in the United States, especially during summer months when swimmers frequent local beaches, despite the region's historically cold water temperatures early in the season. The urgency of the warning follows a reported 42 drownings so far this year across the Great Lakes, underscoring the persistent risks associated with swimming in these waters when weather makes for dangerous conditions. Although most fatalities have occurred at Lake Michigan, life-threatening incidents are possible at all of the Great Lakes, and local officials emphasize prevention and public awareness as critical during peak beach season What to Know The National Weather Service (NWS) issued a warning early Monday for residents and visitors in Wayne, Northern Cayuga, and Oswego counties in the Buffalo, New York, forecast region, cautioning them to stay out of Lake Ontario waters due to strong currents and hazardous swimming conditions. The advisory remained in effect until 11 a.m. local time on Monday. The Beach Hazards Statement specifically warned of "strong currents and dangerous swimming conditions" that could threaten beachgoers in affected counties. The NWS advised people to stay out of the water to avoid potentially life-threatening situations. A person stands on the beach of Lake Ontario in Toronto on September 14, 2023.

Valerie Macon/Getty The NWS's Beach Hazards Statement warned that strong lake currents posed direct threats to swimmers, surfers, and other water enthusiasts in Wayne, Northern Cayuga, and Oswego counties. Similar advisories have been issued across other states bordering the Great Lakes earlier this month, including Illinois, Indiana, Michigan, and Wisconsin, among others. NWS meteorologist Aaron Reynolds told Newsweek that both rip currents and longshore currents posed a risk in the Buffalo area on Monday, although longshore currents were the strongest issue. Reynolds added that winds of 15 to 20 knots, which are 17 to 23 mph, were generating waves of 3 to 5 feet. "Because of that, you can have some strong rip currents," he said. The winds are worse when low-pressure systems move into the area, Reynolds said. However, high pressure is building, which means once the beach hazards statement expires, it likely won't be issued again for at least the next few days. Although the water-related threat is subsiding, a warming trend will soon begin, Reynolds said, which could bring dangerous high temperatures to the region. What People Are Saying NWS Buffalo beach hazards statement: "Stay out of the water to avoid dangerous swimming conditions." NWS Buffalo in a hazardous weather outlook: "Hot and humid conditions are forecast for Thursday, when apparent temperatures could potentially reach the mid 90s to lower 100s across the area. If realized, such conditions would result in an increased risk of heat-related illnesses." What Happens Next While the beach hazards statement for the Buffalo, New York, region was scheduled to expire at 11 a.m. EDT on Monday, officials continued to urge the public to respect all posted advisories and monitor updates from the NWS as weather and water conditions could change rapidly.

Saharan dust is helping limit Atlantic hurricane formation. It won't last much longer
A tropical wave rolled off the coast of Africa a few days ago and began its journey across the Atlantic. But unlike the start of many of the Atlantic basin's worst hurricane stories, this one is likely to have a short ending — thanks in part to a blast of dust from the Saharan desert. The tropical disturbance the National Hurricane Center is currently eyeing is hundreds of miles away from the Caribbean, in a stretch of ocean hurricane scientists call the main development region. In a very active hurricane season, this patch of sea can look more like a conveyor belt, turning newborn tropical disturbances into full-fledged tropical storms or hurricanes. But this system, which only had a 20% chance of strengthening on Monday morning, faces more challenging conditions. For one, there's a lot of hot, dry air that blew off the coast of Africa and surrounded the system. This is known as the Saharan Air Layer, or Saharan dust, and it is known to slow down storms from developing. 'The atmospheric conditions immediately ahead are reasonably conducive to tropical development. They would be very conducive if there weren't so much dry air nearby,' Bryan Norcross, a hurricane specialist at Fox Weather, wrote on his blog. On average, he said, Saharan dust becomes less common in late July. The peak of the hurricane season is August or September, and it's more rare to see a storm throttled by dry, dusty air. Ana Torres-Vazquez, a meteorologist at the Miami office of the National Weather Service, said Saharan dust is just one of multiple factors that can slow down a would-be storm. Sometimes, some of that dust can make it across the entire ocean and end up near Florida, where it can cause brilliant sunsets and aggravate people's lung conditions. Torres-Vazquez said current weather models show a smaller portion of that dust may reach South Florida by the end of the week or early weekend. 'If the weather conditions currently in place hold, some of the remnants of that dust could reach our area, maybe by the late work week,' she said. 'The entirety of that air mass wouldn't make it that far.'
