New topical threat may emerge near Southeast coast by mid-July
Tropical depressions and storms tend to form close to Central America, the Caribbean and the waters adjacent to the southern U.S. early in the hurricane season. The area that gave birth to Chantal has been under close scrutiny by AccuWeather since the middle of June.
The third tropical depression of the 2025 Atlantic hurricane season formed late on Independence Day afternoon, then went on to become Tropical Storm Chantal the next week. Chantal formed in response to a stalled front and a weak dip in the jet stream. Chantal moved inland earlier in the week and brought flooding rain to parts of the Carolinas.
While conditions are likely to remain quiet in the tropical Atlantic for the next few days, the same zone along the southern Atlantic coast has a low chance of brewing another tropical depression or storm spanning July 14-17.
Similar to what meteorologists were monitoring prior to Chantal's formation, development could take place over the northeastern Gulf instead.
For the setup in mid-July, the front is weaker and the jet stream dip is not as pronounced as that of around Independence Day. However, wind shear (disruptive winds) may be a bit lighter compared to earlier in the month. Balancing the concerns out, there is a low chance of development.
Should development take place on the Atlantic side of Florida, it may once again drift northward toward the U.S. coast. Should development occur on the Gulf side of Florida, steering breezes could guide the area of interest westward along the northern Gulf coast.

In either case, showers and thunderstorms can increase in coastal areas and adjacent waters offshore even if a storm center fails to form. Should a center form, more substantial rain and wind, with building surf, would unfold. The next name on the list of tropical storms for the 2025 season is Dexter.
Conditions remain too hostile for tropical development farther to the south from the western shores of Africa through the Caribbean through at least the middle of July.
Vast areas of dry air, dust from the Sahara Desert and disruptive winds are the main factors against development.
The 2025 Atlantic hurricane season is about one month ahead of the historical average, with three named storms already forming. Typically, the third tropical storm does not form until early August, or about a month after Chantal formed. The average date for the first hurricane is Aug. 11, and the first major (Category 3) hurricane generally forms around the start of September.
AccuWeather's team of tropical meteorologists, led by hurricane expert Alex DaSilva, expects 13 to 18 tropical storms, of which seven to 10 will go on to become hurricanes and three to five are likely to evolve into major hurricanes for the 2025 season.

National Hurricane Center issues 1st advisory on Tropical Storm Erin. Any Florida impacts?
Invest 97L quickly strengthened, becoming Tropical Storm Erin this morning, Aug. 11. The National Hurricane Center issued its first advisory on the fifth-named storm of the Atlantic hurricane season at 11 a.m., warning Erin could become a hurricane by Wednesday Aug. 13 and a major hurricane by Saturday, Aug. 16 as it moves quickly west across the Atlantic. ➤ Track all active storms ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location AccuWeather forecasters are predicting Erin could turn north on a parallel path to Florida as it approaches the Caribbean. Elsewhere in the Atlantic, Invest 96L is moving north in the central Atlantic and has a low chance for development. And a new system on NOAA's map is a non-tropical area of low pressure a few hundred miles south-southeast of Nova Scotia. It also has a low chance for development. Here's the latest advisory from the National Hurricane Center as of 11 a.m., Aug. 11: Tropical Storm Erin develops in eastern Atlantic. Expected to become hurricane Invest 97L became Tropical Storm Erin Monday morning, with the National Hurricane Center issuing its first advisory on the system at 11 a.m. Aug. 11. Forecasters are predicting Erin will continue to strengthen as it moves quickly across the Atlantic, becoming a hurricane on Wednesday, Aug. 13, and a major hurricane with 115-mph winds by Saturday, Aug. 16. NOAA hurricane tracker: See spaghetti models for Tropical Storm Erin Special note about spaghetti models: 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. ➤ Track Tropical Storm Erin What tropical waves, disturbances are in Atlantic basin now? How likely are they to strengthen? Invest 96L: A weak trough of low pressure located over the central Atlantic is only producing limited shower and thunderstorm activity. Significant development of this system is becoming unlikely over the next few days as the system drifts generally northward, remaining over the central Atlantic. Formation chance through 48 hours: low, 10 percent. Formation chance through seven days: low, 10 percent. Area of low pressure: A non-tropical area of low pressure is currently located a few hundred miles to the south-southeast of Nova Scotia, Canada. While current shower and thunderstorm activity with the system is limited, this system is drifting over the warm waters of the Gulf Stream where some tropical or subtropical development could occur over the next day or two. By the middle of this week, the system is expected to move northward over cooler waters, ending its changes for further tropical development. Formation chance through 48 hours: low, 10 percent. Formation chance through seven days: low, 10 percent. What is an invest? Short for investigation, the National Hurricane Center uses the term invest for areas of low pressure it is monitoring for potential development into a tropical depression or storm. Invests are not tropical depressions or tropical storms. They're usually clusters of showers and thunderstorms, and just because they've been designated as an invest does not guarantee they'll strengthen into a tropical storm or hurricane. Invests run from 90 to 99, followed by a letter: L for the Atlantic basin and E for those in the eastern Pacific. After 99, it starts over again and the next invest would be 90. Once something has been designated as an invest, specialized data sets and computer models can begin, including scheduling Hurricane Hunter aircraft missions and running spaghetti models. What do the colored, hatched areas on the NOAA map mean? The hatched areas on the National Hurricane Center's tropical outlook map indicate "areas where a tropical cyclone — which could be a tropical depression, tropical storm or hurricane — could develop," said National Hurricane Center Deputy Director Jamie Rhome. The colors make it visibly clear how likely a system could develop, with yellow being low, orange medium, and red high. The National Hurricane Center generally doesn't issue tropical advisories until there is a named storm, but there is an exception. "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," Rhome said. Who is likely to be impacted by Tropical Storm Erin? It's too early at this time to determine if there will be any impact to Florida or the U.S. from Tropical Storm Erin. ➤ Excessive rainfall forecast Erin could bring an increase in rough surf and rip currents to the east coast next weekend and into early next week, even if it curves north, staying away from Florida and the U.S., according to AccuWeather. "The tropics remain quiet, and are likely to stay that way for another 10 days or more," said Ryan Truchelut on Aug. 9. "While there is hope the active peak months of hurricane season may not translate into another awful year in human terms, the reality is that U.S. hurricane impacts are likely and to be expected over the next few months." Truchelut is the chief meteorologist with WeatherTiger and works with the USA TODAY Network. Florida weather radar for Aug. 11, 2025 Weather watches and warnings issued in Florida When is the Atlantic hurricane season? 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 its advisories. When is the peak of hurricane season? The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center. Hurricane names for 2025 season Here are the names for the 2025 Atlantic hurricane season, along with how to pronounce them. The first hurricane of the season typically forms Aug. 11.

Tropical cyclone is the generic term used by the National Weather Service, NOAA and the National Hurricane Center for any tropical system, even if it's in the tropical Atlantic basin. To be more precise, a tropical cyclone is a "rotating, organized system of clouds and thunderstorms that originates over tropical or subtropical waters and has closed, low-level circulation," NOAA sadi. Once maximum sustained winds reach 74 mph, what it is called is determined by where it originated: : for storms in the North Atlantic, central North Pacific, and eastern North Pacific. : for storms in the Northwest Pacific. : for storms in the South Pacific and Indian Ocean.

Tropical Storm Erin forms, expected to become major hurricane by weekend. See Florida impact
Tropical Storm Erin has formed in the eastern Atlantic. Erin is expected to strengthen as it makes its way west across the Atlantic. Current forecasts predict it'll become a major hurricane, with sustained winds of 115 mph, within the next five days. The National Hurricane Center issued its first advisory on the system — one of three in the Atlantic — at 11 a.m. Monday, Aug. 11. ➤ Track all active storms ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location The fifth-named storm of the Atlantic hurricane season, Erin formed earlier than the historical average of Aug. 22. Highlights on what Tropical Storm Erin is doing now Special note on the NHC cone: The 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. Location: 280 miles west-northwest of the Cabo Verde Islands; 2,305 miles east of the northern Leeward Islands Maximum sustained winds: 45 mph Movement: west at 20 mph Pressure: 1,004 mb Next advisory: 8 p.m. CVT; 5 p.m. ET Tropical Storm Erin: What you need to know At 11 a.m. ET Monday, Aug. 11, the center of Tropical Storm Erin was located near latitude 17.4 North, longitude 28.0 West. Erin is moving toward the west near 20 mph, and this motion is expected to continue for the next several days. Earlier satellite wind data indicated that maximum sustained winds are near 45 mph, with higher gusts. Tropical-storm-force winds extend outward up to 35 miles from the center. Gradual strengthening is forecast over the next several days. Spaghetti models for Tropical Storm Erin Special note about spaghetti models: 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. ➤ Track Tropical Storm Erin Is there a hurricane coming toward Florida? Expected impacts from Tropical Storm Erin No tropical storm watches or warnings have been issued for Florida or the United States, and it's too early to tell whether it will impact the U.S. Erin is expected to strengthen into a hurricane by Aug. 13 and become a major hurricane by Aug. 16 as it moves west across the Atlantic. Many models predict it'll curve toward the north before reaching Florida. Even if it does avoid a landfall in Florida, expect a "significant increase in seas, surf and rip currents along the East coast beaches next weekend into the following week," according to AccuWeather. How strong is Tropical Storm Erin and where is it going? The intensity forecast in the short-term is a little tricky, the National Hurricane Center said. "The earlier scatterometer data indicate the system has a small circulation which could be prone to rapid intensity changes, either up or down." Wind shear could limit Erin to slow intensification in the short-term. After that, though, warm sea-surface temperatures could mean Erin becomes a major hurricane within the next 120 hours. A major hurricane is one that is a Category 3 or higher, with at least 111 mph sustained winds. Key messages from the National Hurricane Center: What you need to know about Tropical Storm Erin Tropical Storm Erin formed in the eastern Atlantic Aug. 11, ahead of the historical average for the fifth-named storm of the season. Erin is expected to strengthen as it moves quickly across the Atlantic. Erin could become a hurricane Aug. 13 or early Aug. 14. Current predictions call for Erin to become a major hurricane by Saturday morning, Aug. 16, with maximum sustained winds of 115 mph. Current forecast: Where is Tropical Storm Erin and how strong could it get? As of 11 a.m.: 45 mph 12 hours: 50 mph 24 hours: 60 mph 36 hours: 65 mph 48 hours: 70 mph 60 hours: 80 mph 72 hours: 90 mph 96 hours: 105 mph 120 hours: 115 mph What impact could Tropical Storm Erin have and what areas could be affected? It's still early to tell yet what impacts Tropical Storm Erin could have. Officials warn residents should be prepared and closely monitor the storm that's expected to become a major hurricane later this week. ➤ Excessive rainfall forecast Interactive map: What tropical storms, hurricanes have impacted your area in the past?

The Atlantic may get its first hurricane of the season - and it has the US in its sights
A tropical storm churning in the Atlantic may become not only the first hurricane of the North American 2025 season, but also the first to bring severe tropical storm conditions to the continental U.S. this year. Tropical Storm Erin is gaining power in the eastern Atlantic, according to AccuWeather meteorologists. The storm began as a small cluster of rain storms off the western African coast, but has now intensified and could be designated as a hurricane as soon as Wednesday, according to CNN. While the first hurricane of the season, on average, shows up by August 11, major hurricanes don't typically start forming until at least the first of September. But forecasters believe Erin could be an unseasonably early major storm. That is thanks, in part, to a lack of barriers to its intensification. "Several factors are working in its favor, including lack of dust, warm water and a lack of disruptive breezes," AccuWeather Senior Meteorologist Chad Merrill said. Hurricane season in the U.S. typically lasts from June 1 to November 30. Forecasters believe the storm will move west over the Atlantic for the next week and will then begin a slight northwest curve from Thursday to Friday. That course adjustment should prevent the main body of the storm from hitting the northeast Caribbean. AccuWeather warned that residents of Bermuda and the Bahamas should keep informed about the storm's progression and direction. In some scenarios forecasted, Erin will turns north and away from the U.S. But if the storm becomes powerful, the tropical storm conditions at its periphery could stretch for 100 miles or more, meaning even a northward turn might bring severe storms, high winds, and damaging surf and rain to the coastal U.S. In that scenario, the east coast of the U.S. from North Carolina to New England would likely bear the brunt of the storm. "Any development could bring impacts for a large swath from the Caribbean to the United States East Coast," AccuWeather warned in a social media post. The National Oceanic and Atmospheric Administration announced that it would release advisories on Tropical Storm Erin sometime on Monday. If storm does spin up into a hurricane, it will become the first hurricane in a season that the NOAA predicts will be more active than usual. The NOAA believes between 13 and 19 named storms will whip up, and of those that approximately six to 10 will become full fledged hurricanes — with wind speeds of 74 miles per hour or greater. The NOAA believes three to five hurricanes will become major Category 3, 4, or 5 storms, which have 111 mph wind speeds or greater. The federal agency said it had 70 percent confidence in its forecast. 'This outlook is a call to action: be prepared. Take proactive steps now to make a plan and gather supplies to ensure you're ready before a storm threatens," NOAA's National Weather Service Director Ken Graham said in a statement.
