Tropical Storm Erin to become major hurricane soon: See tracker
According to a 5 a.m. ET advisory from the NHC on Aug. 13, Erin was located about 1,400 miles east of the northern Leeward Islands with maximum sustained winds around 45 mph with higher gusts. Erin is currently moving west near 20 mph, and this motion is expected into Thursday, according to forecasters.
A west-northwestward motion is expected to begin Thursday night and will continue into the weekend, with the center of Erin likely to move near or just north of the northern Leeward Islands over the weekend.
"Gradual strengthening is forecast to begin today, and Erin will likely become a hurricane by late Thursday or early Friday," the hurricane center said in the Aug. 13 advisory. A major hurricane is a term used for cyclones rated a Category 3 or higher with sustained wind speeds over 110 mph.
Forecasters are urging interests in the northern Leeward Islands, Virgin Islands, and Puerto Rico to monitor the progress of Erin, as the storm could produce impacts on those islands this weekend. The magnitude of those impacts, however, is still not known.
Most reliable computer models that meteorologists use to forecast storms show Erin curving away from the United States, spinning off the East Coast in mid-August.
"It is too soon to discount – or pinpoint – USA landfall impacts from Erin, but based upon current model guidance – the chance RIGHT NOW is low, at less than 10%," said Weather Trader meteorologist Ryan Maue in an email to USA TODAY Aug. 11.
WPLG-TV hurricane specialist Michael Lowry added a note of caution, telling USA TODAY that "it's worth reiterating that forecasts 5 to 10 days out are subject to large errors, so we'll need to hang tight before confidently giving the U.S. the all-clear."
However, even if Erin does avoid landfall on the United States, "there will be a significant increase in seas, surf, and rip currents along the East Coast beaches next weekend into the following week," AccuWeather senior meteorologist Chad Merrill said.
Will Erin hit the US?: Will Tropical Storm Erin hit the US or turn? Here's what early forecasts say.

NHC keeping tabs on 2 other systems in Atlantic, Henriette weakens in Pacific
Elsewhere in the Atlantic, the hurricane center said it is tracking a tropical wave over the northwestern Caribbean Sea that is producing disorganized showers and thunderstorms.
This system is forecast to move west-northwestward and cross the Yucatan Peninsula later today with no significant increase in organization, the hurricane center said on Aug. 13. Some development of this system is possible after it emerges across the southwestern Gulf beginning Aug. 14, however the NHC gives it a 20% chance of formation through the next seven days.
Additionally, the hurricane center said a non-tropical area of low pressure located a few hundred miles southeast of Nova Scotia, Canada, is producing showers and thunderstorms.
Limited tropical or subtropical development is still possible on Aug. 13 as the system lingers near the warm waters of the Gulf Stream; however, it is forecast to move northward over cooler waters, which will diminish its chance for tropical development.
In the Pacific, Henriette has weakened into a post-tropical cyclone with maximum sustained winds near 45 mph with higher gusts. Hurricane center forecasters said Henriette should continue to weaken and dissipate later this week.
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. 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 reach 39 mph. When its winds reach 74 mph, the storm officially becomes a hurricane.
Prepare now for hurricanes
Delaying potentially lifesaving 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," the National Oceanic and Atmospheric Administration recommends.
Develop an evacuation plan. If you are at risk from hurricanes, you need an evacuation plan. Now is the time to begin planning where you would go and how you would get there.
Assemble disaster supplies. Whether you're evacuating or sheltering in place, you're going to need supplies not just to get through the storm but for a possibly lengthy aftermath, NOAA said.
Get an insurance checkup and document your possessions. Contact your insurance company or agent now and ask for an insurance checkup to make sure you have enough insurance to repair or even replace your home and belongings. Remember, home and renters insurance doesn't cover flooding, so you'll need a separate policy for it. Flood insurance is available through your company, agent or the National Flood Insurance Program. Act now, because flood insurance requires a 30-day waiting period.
Create a family communication plan. NOAA says you should take the time now to write down a hurricane plan and share it with your family. Determine family meeting places and make sure to include an out-of-town location in case of evacuation.
Strengthen your home. Now is the time to improve your home's ability to withstand hurricanes. Trim trees; install storm shutters, accordion shutters, and impact glass; seal outside wall openings.

Caribbean officials warn of heavy rains and big waves as Tropical Storm Erin nears
The storm is expected to remain over open waters and move north-northeast of islands including Antigua and Barbuda, the U.S. and British Virgin Islands, and Puerto Rico, according to the National Hurricane Center in Miami. Erin was located about 790 miles east of the Northern Leeward Islands. It had maximum sustained winds of 60 miles per hour and was moving west at 17 miles per hour. Tropical storm watches were in effect for Anguilla and Barbuda; St. Martin and St. Barthelemy; Saba and St. Eustatius; and St. Maarten. Advertisement Erin is forecast to become a hurricane by Friday and strengthen into a Category 3 storm by late Saturday, which would mark the first major storm this season. 'Erin is moving into an area of the Atlantic primed for rapid intensification. The waters are incredibly warm,' said Alex DaSilva, lead hurricane expert for AccuWeather. Tropical-storm force winds could occur in parts of the northern Leeward Islands, the US and British Virgin Islands and Puerto Rico this weekend, forecasters said. 'There is still 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 in the long range,' the hurricane center said. Advertisement Hurricane specialist and storm surge expert Michael Lowry said nearly all models have Erin turning 'safely east of the broader U.S. next week.' Erin is the fifth named storm of the Atlantic hurricane season, which runs from June 1 to Nov. 30. Forecasters are expecting another unusually busy season for the Atlantic, with predictions calling for six to 10 hurricanes, with up to half reaching major status. The Trump administration has slashed the number of employees at many of the agencies traditionally responsible for planning for and responding to natural disasters, including NOAA, the National Weather Service, and the Federal Emergency Management Agency. So far, it is unclear how those cuts might affect the accuracy of forecasts. The weather service may begin hiring again soon. Several disturbances will follow behind Erin. Another wave of unsettled weather may reach the Caribbean later next week. The Hurricane Center is also monitoring a disturbance moving across the sultry waters of the Bay of Campeche and southern Gulf of Mexico. The system is forecast to cause scattered downpours in eastern Mexico and Texas on Friday and Saturday. There's a chance it could develop into a short-lived tropical depression or storm. The next storm names after Erin are Fernand, Gabrielle, and Humberto.

What Hurricane Models Can (and Can't) Tell Us About Tropical Storm Erin
As Tropical Storm Erin moves west toward the Caribbean islands and the official forecast from the National Hurricane Center shows the storm likely beginning to curve — potentially even away from the United States — the center's forecasters have exercised caution, consistently warning that there is a 'greater than normal uncertainty' about where the storm will go after the weekend. But why?The uncertainty has to do with quite a few factors, but a main one is the output of the computer weather models that help meteorologists make their forecasts. Specifically, it's a type of map called a spaghetti plot showing where a computer simulation predicts the center of the storm will be five, seven or even 14 days in the future. These mapped model outputs get their name from their resemblance to long strands of pasta. The closer the lines are together, the more confidence forecasters have in what the storm might do, because it means many of the models agree with one another. For the next few days, there is a pretty reliable consensus that the storm will track northwest. But how much and when it might turn north or even northeast are still big questions. 'The confidence in the predicted location is less at, say, five days, than at two days, said Richard Pasch, an expert at the Hurricane Center. 'In the case of Erin, the model spread increases beyond five days, but not unusually so.' 'It should be noted,' he added, 'that the typically greater uncertainty in the forecasts at six and seven days is the main reason why the National Hurricane Center does not currently issue official forecasts at these longer time ranges.'In 2017, Hurricane Irma, which formed in a similar position to Erin's, was forecast to make a similar curve, but instead it kept moving west, hitting the Caribbean islands and eventually disrupting the west coast of Florida. And Erin is currently in a similar position in the Atlantic Ocean to where Hurricane Lee was in 2023, which did make a turn, allowing it to pass over cooler waters and weaken before hitting Canada. Then there was Hurricane Gloria in 1985, another storm with a similar path to Erin's, which knocked out power to millions of customers and disrupted the lives of millions of people from North Carolina to New England. Previous storm paths The New York Times 'I thought a Gloria track might be possible, but it is looking pretty unlikely that we will see a U.S. landfall from Erin,' Phil Klotzbach, a hurricane expert at Colorado State University, said on Thursday of the hardest parts of any hurricane forecast is trying to predict when a storm will turn and how much of a turn it might like Mr. Klotzbach look for a pattern to help build their confidence around where a storm is most likely to go. The computer models typically run four times a day. After each, forecasters look to see if there have been changes from the last one. Consistency between outputs is one thing forecasters watch for. But if there is a significant change, they usually wait for another model run to make substantial adjustments to the guidance they turn around and share with the aren't just worried about where the storm will go — they are also concerned about how intense the storm might become. While forecasters can use one model to monitor intensity, they usually prefer to look at all of them. To do this, they often plot different forecast intensities on a chart that progresses over time. This line plot gives forecasters an idea of what could happen. Similar to the map plots, the tighter the lines are together between models, the more confident the forecasters are about the intensity. Sometimes they might say the official forecast is below the model guidance, or, as happened Thursday morning, they may say the official forecast was below some of the guidance. This suggests that some models indicate Erin could strengthen more than expected over the next five days. As of Thursday afternoon, the Hurricane Center is saying Erin could grow at least as strong as Category 3 by next week.

Tropical Storm Erin tracker: Forecast to strengthen into 1st Atlantic hurricane of 2025 by Friday, latest projected path prompts watches for northern Leeward Islands
There is still uncertainty about what impact Erin may have on states like Florida on the U.S. East Coast, NHC forecasters say. Tropical Storm watches are now in effect for parts of the northern Leeward Islands as Erin is expected to become the first hurricane of the 2025 Atlantic hurricane season by Friday, according to forecasters at the National Hurricane Center. Erin formed in the eastern Atlantic Ocean on Monday and is strengthening as it moves westward. The NHC said there is still "a greater than normal uncertainty" about what impact it could have on states like Florida on the U.S. East Coast, as well as the Bahamas and Bermuda. But forecasters remain confident that Erin "will be a large and powerful hurricane over the southwestern Atlantic Ocean this weekend." Where is Tropical Storm Erin, and what is its path? As of 5 p.m. ET Thursday: Erin was located 790 miles east of the northern Leeward Islands. The storm has maximum sustained winds of 60 mph. It is moving west at 17 mph. "A turn toward the west-northwest is expected tonight, with this motion expected to continue 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." The storm is expected to bring areas of heavy rainfall starting late Friday across the northern Leeward Islands, the U.S. and British Virgin Islands, as well as southern and eastern Puerto Rico. Rainfall totals could range from 2 to 4 inches, with up to 6 inches in isolated areas, which could lead to flash or urban flooding and cause mudslides and landslides, the hurricane center said Thursday. What are the chances it will intensify? Tropical Storm Erin is expected to strengthen in the next day or so and is forecast to become a hurricane by Friday, forecasters said. A tropical storm becomes a hurricane when maximum sustained winds reach at least 74 mph. Hurricanes are rated on the Saffir-Simpson Hurricane Wind 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 5 p.m. ET Thursday, these are the following advisories in place, according to the NHC: Tropical storm watch in effect for: Anguilla and Barbuda St. Martin and St. Barthelemy Saba and St. Eustatius Sint Maarten A 'tropical storm watch' means tropical storm conditions are possible in the areas within the next 48 hours. 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.
