Tropical Storm Dexter formed in the western Atlantic late Sunday, marking the fourth named storm of the 2025 Atlantic hurricane season, according to the National Hurricane Center (NHC).
As of 11 p.m. ET on Sunday, Dexter was located about 300 miles west-northwest of Bermuda, moving east-northeast at 12 mph with maximum sustained winds of nearly 45 mph. NHC forecasts indicated the storm would track away from the U.S. coast and was not an immediate threat to land.
Why It Matters
Tropical Storm Dexter's formation comes during what meteorologists predicted to be an above-average hurricane season, with the National Oceanic and Atmospheric Administration (NOAA) forecast predicting 13 to 19 named storms in 2025. Last year's hurricane season saw 18 named storms, 11 hurricanes, and significant devastation—including more than $113 billion in damage from Hurricanes Helene and Milton.
As the Atlantic hurricane season peaks from August to October, the tracking and forecasting of Dexter and other evolving disturbances are critical for preparedness in vulnerable regions. Even distant tropical storms can pose risks such as inland flash flooding and dangerous rip currents, which remain a leading cause of hurricane-related deaths.
What To Know
There is a possibility Dexter will strengthen slightly before it is expected to become post-tropical by midweek. The NHC projects it will remain over open waters, north of Bermuda, and away from the U.S. East Coast.

Alongside Dexter, the NHC is monitoring a tropical wave expected to move off Africa's west coast. That system has a 40 percent chance of forming into a tropical depression this week as it travels west-northwest across the Atlantic.
Meanwhile, an emerging low-pressure zone off the U.S. Southeast coast has about a 20 percent chance of development over the next seven days, the NHC said. Neither of these systems pose an immediate threat to land, but forecasters caution that conditions could change.
How Tropical Storms Form
Tropical storms develop from clusters of thunderstorms over warm ocean waters, especially where atmospheric conditions allow for sustained convection and low wind shear. As these systems organize, they may become tropical depressions, then tropical storms with wind speeds of more than 39 mph. If winds exceed 74 mph, they are categorized as hurricanes.
Atlantic hurricane activity typically increases between August and October, fueled by warm sea surface temperatures. Scientists have noted that climate change is leading to warmer ocean waters, which can result in faster-developing and more powerful storms.
The Atlantic hurricane season lasts from June 1 to November 30. The bulk of tropical activity tends to occur between mid-August and early October. As of August 2025, Dexter is the fourth named storm, and the next would be called Erin if it forms. Residents and businesses are urged to keep informed through official weather alerts as the season progresses. [News-Journal Online, Aug. 3, 2025]
What People Are Saying
National Hurricane Center forecasters said in an official advisory on August 3, 2025: "Dexter is expected to continue moving away from the U.S. east coast and remain north of Bermuda over the next few days."
What Happens Next
Dexter is forecast to strengthen slightly before becoming a post-tropical system by Wednesday.

Tropical Storm Dexter Has Formed in the Atlantic — Here's Where It's Expected to Go and When
Forecasters believe the storm will continue moving in the same general direction over the next few daysNEED TO KNOW Tropical Storm Dexter has formed in the Atlantic, making it the fourth named storm of the season The storm developed late on Sunday, Aug. 3 and is expected to continue moving to the northeast NOAA has predicted there will be between 13 and 19 named storms in the Atlantic this hurricane season, which began June 1A new tropical storm has formed off the coast of the United States. Tropical Storm Dexter developed late on Sunday, Aug. 3, according to The Weather Channel and FOX Weather. As of the morning of Monday, Aug. 4, the storm was located about 250 miles west of Bermuda with maximum sustained winds of 45 mph, according to the National Hurricane Center (NHC) in Miami, Fla. By the afternoon, the storm was 275 miles away from Bermuda. The storm is currently moving northeast, away from the United States, at about 14 mph, a pattern that is expected to continue for the next few days. 'Some slight strengthening is forecast during the next couple of days,' forecasters said, 'but Dexter is likely to become a post-tropical cyclone by the middle to latter portion of this week.' Despite the fact that it's moving away from the United States, Fox Weather reported that rip tides will pose a threat to beachgoers across the East Coast from New York to South Florida. The storm is expected to dissipate in the Atlantic Ocean over the course of the week, according to Fox affiliate WTVT-TV. This is just the fourth named storm in the Atlantic since the hurricane season began on June 1. Storms are named once they reach tropical storm status, which occurs when a storm reaches maximum sustained surface winds of at least 39 mph, according to the National Weather Service (NWS). Earlier this year, the National Oceanic and Atmospheric Administration (NOAA) predicted a 60% chance of an above-normal hurricane season in the Atlantic. The agency predicted there would be between 13 and 19 total named storms, with six to 10 of them becoming hurricanes. Three to five of those hurricanes are forecast to be major hurricanes, which have winds of 111 mph or higher. At the time, Commerce Secretary Howard Lutnick said forecasters 'have never been more prepared for hurricane season.' 'NOAA and the National Weather Service are using the most advanced weather models and cutting-edge hurricane tracking systems to provide Americans with real-time storm forecasts and warnings,' Lutnick said. The NHC also says there is a chance for two more systems in the Atlantic to develop into tropical cyclones in the next week or so.

The first disturbance is located in the Central Atlantic, and has a 50% chance of developing within the next seven days as it heads west-northwest. Forecasters say it could develop into a tropical depression 'by the latter portion of this week." The second disturbance is located just off the coasts of northeastern Florida, Georgia and South Carolina. This 'broad area of low pressure' has a 30% chance of developing over the next seven days as it 'slowly moves' to the west. Read the original article on People

Two Atlantic systems being monitored as Tropical Storm Dexter moves away from U.S.
Tropical Storm Dexter continues to track northeastward between eastern Canada and Bermuda, posing no threat to land, while forecasters are keeping an eye on two additional systems in the Atlantic with potential for development later this week. As of Monday, Dexter is moving at 15 mph northeastward and is expected to stay over open waters, well away from the U.S. East Coast. The storm maintains winds between 45 and 50 mph and is forecast to remain a tropical storm for the next two to three days before becoming post-tropical over the North Atlantic. Although Dexter will not approach land, its sustained winds are expected to kick up seas along parts of the northeastern U.S. and eastern Canada. Forecasters say a low-pressure system may develop by midweek just off the Florida Peninsula, stretching as far south as West Palm Beach. While the system is expected to remain close to South Florida, any development would likely move north-northwest along the Southeast coast. As of now, the National Hurricane Center has given it a 0% chance of development over the next 48 hours. Another area of interest is a tropical wave moving off the west coast of Africa on Monday afternoon. It is expected to travel west-northwest this week across the central tropical Atlantic. Gradual development could occur later this week or into the weekend, with the potential for a tropical depression to form. Forecasters said the system's long-range track remains uncertain, and it will be monitored over the next week and a half.

Tropical Storm Dexter forms in the Atlantic, while other areas of interest develop
Sea surface temperatures begin to heat significantly in August, and the average sea surface temperature across the Northern Atlantic, as a whole, is currently the third warmest on record. This has helped raise the alert on two other areas of interest that are worth watching over the next week. Showers and thunderstorms may run out of room to organize into a named storm before moving inland over the Carolinas, but should still produce rounds of heavy, tropical-like rainfall regardless. A tropical wave coming off the west coast of Africa is already showing signs of storm development, and environmental conditions will become more favorable for a tropical depression to form later this week. Advertisement Two areas of interest have the potential to form into tropical storms over the next week. Boston Globe We've seen a strong Bermuda high throughout July, which delivered stronger than normal wind shear across the Tropical Atlantic and into the Caribbean, suppressing tropical activity over the last few weeks. But we're starting to see the high begin to weaken, which does a couple of things. One, a weaker Bermuda high slows wind shear and creates a more stable environment for storms to develop and sustain. And two, the rate of evaporation with the weaker winds will increase sea surface temperatures, providing more fuel for storms to organize more quickly. Advertisement The chart below shows the forecast wind shear over the next two weeks with blue shading indicating weaker winds. Wind shear over the tropical Atlantic is forecast to be weaker than normal over the next two weeks (blue shading). NOAA These are great clues to suggest we're about to see the Atlantic hurricane season have an above-average month in terms of the number of storms. Dexter has become the fourth named storm of the season, which doesn't typically occur until Aug. 15. The first hurricane does not usually form until Aug. 11. This graph details the number of storms throughout the average hurricane season. The fourth named storm typically arrives later in mid-August. University of Miami I'd be willing to bet that we'll have the first named hurricane of the season on or before the average date. The next named storm will be Erin. Ken Mahan can be reached at
