Tropical Storm Erin tracker: Forecast to strengthen into 1st Atlantic hurricane of 2025 this week, as latest projected path is updated
Tropical Storm Erin is expected to become the first hurricane of the 2025 Atlantic hurricane season in a few days, according to forecasters at the National Hurricane Center.
Erin formed in the eastern Atlantic Ocean on Monday and continues to move westward. The NHC said there is still great uncertainty about what impacts it could have on the U.S. East Coast, the Greater Antilles and the Bahamas, but added that now is a good time to make sure preparedness plans are in place.
Where is Tropical Storm Erin, and what is its path?
As of 11 a.m. ET Wednesday:
Erin was located 1,305 miles east of the northern Leeward Islands.
The storm has maximum sustained winds of 45 mph.
It is moving west at 17 mph.
"This general motion is expected to continue into Thursday, with a west-northwestward motion beginning Thursday night and continuing into the weekend," the NHC said. "On the forecast track, the center of Erin is likely to move near or just north of the northern Leeward Islands over the weekend."
What are the chances it will intensify?
The NHC's intensity forecast shows Tropical Storm Erin could become a hurricane "in a couple of days," according to the agency's Wednesday morning public advisory. "Gradual strengthening is forecast to begin today, and Erin will likely become a hurricane by late Thursday or early Friday," forecasters said.
A tropical storm becomes a hurricane when maximum sustained winds reach at least 74 mph. Hurricanes are rated on a scale ranging from Category 1 to Category 5, with 5 being the most severe. A storm is considered a major hurricane when it reaches Category 3 strength, with sustained winds of at least 111 mph, according to the NHC.
Watches and warnings in place
As of 11 a.m. ET Wednesday, there were no coastal watches or warnings in effect.
"Swells generated by Erin will begin affecting portions of the northern Leeward Islands, the Virgin Islands and Puerto Rico by this weekend," the NHC said. "These swells are likely to cause life-threatening surf and rip current conditions. Please consult products from your local weather forecast office."
How is hurricane season shaping up?
The 2025 Atlantic hurricane season, which began June 1 and runs through the end of November, has a 50% chance of being above normal.
Last week, forecasters at the National Oceanic and Atmospheric Administration slightly updated the number of expected storms to 13-18 (estimated at 13-19 in May), five of which could become major hurricanes (with winds of more than 111 mph).
A typical hurricane season averages 14 named storms. We're currently about halfway through this year's hurricane season, and there have been five so far: tropical storms Andrea, Barry, Chantal, Dexter and Erin.

Tropical Storm Erin forecast to be hurricane by Friday
Aug. 13 (UPI) -- Tropical Storm Erin is slightly intensifying and forecast to become a hurricane on Friday morning over the central tropical Atlantic with a chance of ultimately affecting the U.S. East Coast, the Bahamas and Bermuda next week, the National Hurricane Center said Wednesday. For the first time since Erin became a tropical storm Monday morning, intensity increased, though just 5 mph, to maximum sustained winds of 45 mph, with gradual strengthening during the next two days forecast, the NHC said in its 5 p.m. EDT update. In the 11 p.m. update, Erin remained at 50 mph. Erin is forecast to reach hurricane status by 8 a.m. Friday with winds at least 74 mph, and a major hurricane, with winds of at least 111 mph, by 8 p.m. Sunday. It would be the first hurricane of the Atlantic season. Beryl was the first hurricane last year on June 24. The storm is about 1,095 miles east of the Northern Leeward Islands. Erin was moving westward at 16 mph and will shift to a north-westward track beginning Thursday night and into the weekend, the NHC said. On the forecast track, the storm's center will move over or near just north of the northern Leeward Islands. The NHC's "cone" doesn't track Erin past Monday night, and NHC forecasters remind that they have an average error of 150 to 214 miles at days four and five. In the latest discussion, NHC forecaster Jack Beven said there is a "greater than normal uncertainty about what impacts Erin may bring to portions of the Bahamas, the East Coast of the United States and Bermuda." But he said: "The risk of dangerous surf and rip currents across the western Atlantic basin next week is increasing." By this weekend, swells are forecast to cause life-threatening surf and rip current conditions, the NHC said. Alex Sosnowsky, an AccuWeather senior forecaster, said there is concern that residents, visitors, cruise lines, and shipping and fishing ventures "could pass paths with a powerful hurricane." With a track farther to the east, Bermuda could be directly in the path as a major hurricane. He said a farther west scenario would mean a greater risk of strong winds, rain and coastal flooding in the U.S., including eastern North Carolina, Long Island, New York and southeastern New England. "Families heading to U.S. Atlantic beaches for a late-summer vacation next week need to be extremely cautious when venturing into the surf," AccuWeather Lead Hurricane Expert Alex DaSilva said. "More than 50 people have lost their lives to rip currents and rough surf at beaches across the country so far this year, without any major hurricane nearby." There are no warnings or coastal watches in effect as tropical-force winds extend outward up to 60 miles. But those in the northern Leeward Islands, the Virgin Islands and Puerto Rico should monitor Erin's progress. The previous four named Atlantic storms this year were Andrea, Barry, Chantal and Dexter. None of them became hurricanes, and Chantal was the only one to make landfall in the United States, causing significant flooding in North Carolina. Helene struck that state last year as a tropical storm, causing an estimated $53 billion in damage, after hitting western Florida as a Category 4 hurricane. Four other hurricanes made landfall in the United States in 2024: Beryl, Debby, Francine and Milton.

Tropical Storm Erin's path uncertain as steering patterns shift in Atlantic
[Tropical Storm Erin]( the fifth named storm of the 2025 Atlantic hurricane season, is on schedule for a long journey across the ocean — but its final location is still unknown. The National Hurricane Centre now predicts Erin will strengthen into a Category 1 hurricane by the end of the week, with the possibility of intensifying further over the weekend. Favourable conditions, such as low wind shear, are expected to support development. RELATED: Two possible tracks emerging The storm's impact will be dependent on how the upper-level steering patterns change over the next few days. By Sunday, high pressure is expected to rebuild over the Atlantic Ocean, potentially pushing the hurricane westward and closer to the U.S. eastern seaboard. Another potential outcome is that a diving trough sweeping across eastern Canada will absorb the storm and direct it towards Atlantic Canada. Forecasters say the precise timing of this trough is a major uncertainty. MUST SEE: Risks remain despite uncertainty Even without a clear track, the likelihood of dangerous surf and rip currents is expected to increase along certain sections of the shoreline. Meteorologists warn that minor changes in the storm's path could result in significant differences in who experiences impacts. Forecasters will continue to closely monitor the storm in the coming days, with a more complete picture expected early next week.
