The first hurricane of the 2025 season is expected to develop soon west of Mexico in the Pacific. Tropical Storm Barbara is forecast to strengthen into a hurricane today, June 9. Tropical Storm Cosme is expected to near hurricane strength today, before weakening June 10.
Another large plume of dust moving off Africa could reach Florida around June 13, according to AccuWeather.
Here's the latest advisory from the National Hurricane Center as of 8 a.m., June 9:
The National Hurricane Center is monitoring two tropical waves in the Atlantic:
Tropical wave 1: A tropical wave located at 37W from 02N-12N in the central Atlantic is moving west at 11 mph.
Tropical wave 2: A central Atlantic tropical wave east of the Caribbean Sea has its axis along 57W south of 17N, is moving west at 11 to 17 mph.
Now is the time to prepare for a hurricane, before a storm is approaching.
While conditions in the Atlantic basin have been quiet since the June 1 start of the 2025 hurricane season, that's not the case in the eastern Pacific.
Currently, there are two tropical storms — Barbara and Cosme — west of Mexico and a tropical depression is expected to form later in the week or during the weekend, according to the National Hurricane Center. Tropical Storm Alvin formed in late May.
➤ First hurricane of 2025 season expected to develop in Pacific. Where are 2 tropical storms?
Tropical Storm Barbara is expected to become a hurricane later today, June 9.
Tropical Storm Cosme is forecast to be near hurricane strength later today or tonight before weakening June 10.
Historically, tropical cyclones form close to the U.S. in June, with the most common locations being the northwestern Caribbean and the eastern Gulf, according to Dr. Ryan Truchelut, chief meteorologist with WeatherTiger. Truchelut is a Florida meteorologist who works with the USA TODAY Network.
"None of the reputable forecast models are showing a realistic chance of anything tropical forming on the Atlantic side of Central America through mid-month."
➤ WeatherTiger: False alarms, beneficial rain and a dusty start to Florida storm season
The exception is the GFS model, which is predicting a Caribbean tropical storm will spin up in 10 to 12 days, then move generally northward, Truchelut said.
"The GFS has a persistent and well-known bias for incorrectly predicting development in the Caribbean at this specific time of year," Truchelut said. "All told, while something could eventually spin up in two or three weeks, the GFS' frequent false alarms should be disregarded."
Pensacola, western Panhandle: Showers and thunderstorms forecast. A slight risk of severe weather expected through tonight.
Tallahassee, central Panhandle: Showers expected to slowly diminish through the morning but storms could develop this afternoon and into the evening. Some storms could be strong, bringing wind gusts up to 60 mph and quarter-sized hail.
Jacksonville, North/Northeast Florida: Severe thunderstorms will be possible Monday afternoon and evening along and north of I-10. Main threats with strong storms will be damaging winds around 60 mph, frequent lightning, locally heavy rainfall and possible minor flooding in areas that have received multiple days of rain.
Daytona Beach to Stuart, East/Central Florida: It'll be hot and humid, near 90 at the coast and low to mid 90s inland. Peak heat indices range between 99 and 104. UV Index will be extreme. Isolated to scattered afternoon and evening lightning storms forecast.
West Palm Beach to Naples, South/Southwest Florida: A few isolated storms will be possible across interior today, while hot and sunny conditions continue across metro areas.
Fort Myers to Sarasota, West/Southwest Florida: After a few days of low rain chances, a change in the weather pattern is on the horizon. Increasing moisture will allow for higher chances of showers and thunderstorms each day, mainly in the afternoon and evening
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.
The peak of the season is Sept. 10, with the most activity happening between mid-August and mid-October, according to the Hurricane Center.
Systems currently being monitored by the National Hurricane Center include:
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 said.
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.

National Hurricane Center now tracking 4 waves in Atlantic, Caribbean, rain from Gulf system
The low-pressure system bringing rain and thunderstorms across Florida the last few days is expected to move out of the Gulf inland over southeastern Texas or western Louisiana going into the weekend, ending any chances for further development, according to the National Hurricane Center's July 25 update. "Today will be the last day of widespread heavy rainfall across the Gulf Coast," said National Weather Service meteorologist Mussie Kebede. "Troughing along the coast has offered a lifting mechanism for storm development/organization over the last few days, but should wind down as an upper ridge in the vicinity strengthens. "1-3 additional inches of rain are anticipated from the Florida panhandle to the central Texas coast by Sunday morning. Fortunately, the threat of flash flooding remains marginal due to the relatively low rain rates, resilient soils and efficient runoff methods," the forecaster said. Elsewhere, the NHC is now tracking four tropical waves moving westward across the Atlantic: one near the Lesser Antilles, one in the open Atlantic, a third off the coast of Africa, and a new one in the Caribbean. It's still hot out there. Heat index values ('real feel" temperatures) are expected to reach 100-107 in different areas around the state, but there are no heat advisories in effect today. However, the unusual heat and humidity the country has suffered through the last week will continue through early next week, Labede said, while building across the Southeast and Mid-South this weekend. ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location The next named storm of the 2025 Atlantic hurricane season will be Dexter. Historically, the fourth named storm of the Atlantic hurricane season arrives Aug. 15. The last two named storms of the season — Barry and Chantal — developed earlier than normal. Here's the latest tropical advisory from the National Hurricane Center as of 8 a.m. July 25: Where is the low-pressure area? A broad area of low pressure located about 100 miles south of the coast of southwestern Louisiana continues to produce disorganized showers and thunderstorms. This system is moving west-northwestward toward the Texas coast, and it has limited time to develop before it moves inland tonight. Regardless of formation, locally heavy rainfall is likely over portions of the northwestern Gulf coast during the next couple of days. Formation chance through 48 hours: Low, 10% Formation chance through 7 days: Low, 10% What else is happening in the tropics? The National Hurricane Center is tracking four tropical waves. Tropical wave 1: A tropical wave is analyzed over the eastern Atlantic near 20W, from 17N southward moving westward at 10 to 15 kt. Isolated moderate convection is depicted just west of the wave axis. Tropical wave 2: A central Atlantic tropical wave is near 40W, from 18N southward, moving west at 10 to 15 kt. No significant convection is active with this wave. Tropical wave 3: A central Atlantic tropical wave is near 56W, from 18N southward, moving at 20 to 25 kt. Scattered showers and thunderstorms are active from 10N to 14N between 54W and 57W. Tropical wave 4: A Caribbean tropical wave is analyzed near 76W, from 19N southward moving west at 25 kt.

Storm tracker: System could bring heavy rain in Gulf from Florida to Texas
A stretch of the Gulf Coast from the Florida panhandle to the central Texas coast could see heavy rain this weekend due to a broad area of low pressure currently over the north-central Gulf. The National Hurricane Center said in a July 25 advisory the area of low pressure is currently producing "an area of disorganized showers and thunderstorms." Hurricane center forecasters said slow development of this system is possible over the next day or so as it moves west-northwest across the northern Gulf. However, by this weekend the system is likely to move inland over southeastern Texas or western Louisiana, ending its chances for development. The National Weather Service said early Friday morning 1 to 3 inches of rain are expected from the Florida panhandle to the central Texas coast by Sunday morning, however the threat of flash flooding remains "marginal." Hurricane center forecasters give this system a 10% chance of formation through the next seven days. NHC also keeping an eye on two systems in the Pacific The NHC also said in its July 25 advisory it is keeping an eye on disorganized showers and thunderstorms associated with an area of low pressure located well southeast of the Hawaiian Islands. Forecasters said gradual development of this system is possible, and a tropical depression could form late this weekend or early next week as it moves generally westward across the far western portion of the eastern Pacific and into the Central Pacific basin. The NHC gives this system a 40% chance of formation through the next seven days. Additionally, an area of low pressure is forecast to form offshore of the southwestern coast of Mexico early next week, according to the hurricane center. Thereafter, environmental conditions appear conducive for some development as the system moves west-northwestward. The NHC says the system has a 20% chance of formation through the next seven days. Storm tracker This 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. 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.

National Hurricane Center watching another potential storm off Southeast coast
Signals strung out across the Atlantic Ocean indicate the 2025 hurricane season may be kicking into a more active gear in the days ahead, but a disturbance a little closer to the U.S. has drawn the attention of the National Hurricane Center. In a July 22 update, the hurricane center flagged a low pressure area off Northeast Florida that showed some chance of developing after it crosses over Florida into the Gulf of America, renamed from the Gulf of Mexico, later in the week. The system is forecast to move in a west-southwestward direction into the north-central Gulf where it may encounter conditions that could allow for some slow development if it remained far enough from shore, according to a hurricane center update from Philippe Papin, a hurricane specialist. Papin's forecast put the chances of development at only 10% over seven days, predicting the system is likely to move inland by the weekend. Either way it's likely to mean a few more days of heavy rain along the northern Gulf Coast, forecasters say. "Expect rain and storm chances to increase towards the end of the week as this disturbance moves in, though it's too early to say much with certainty beyond that," the National Weather Service office in Houston posted on its social media. In Lake Charles, Louisiana, the weather service noted the amount of moisture in the air is expected to surge to the maximum amount possible by the afternoon of July 24. Deja vu disturbance? If the hurricane center's tropical outlook map looks familiar, that's because a similar scenario has played out twice in recent weeks. On July 5, Tropical Storm Chantal formed from a low pressure area off the southeastern United States. Chantal went on to cause flooding in parts of North Carolina, and was blamed for at least six deaths. Then on July 12, the hurricane center started watching another potential low pressure area off the southeastern coast, which then slogged across the Florida peninsula with heavy rain on July 15 and then along the state's Panhandle. It remained disorganized and moved over southeastern Louisiana on July 17. Chantal was a little earlier than normal for the third named storm of the season, according to Phil Klotzbach, a research scientist and co-author of a seasonal outlook from Colorado State University. On average the third named storm of the Atlantic hurricane season forms on August 3. After all the seasonal outlooks predicting a busy season, it may seem like the 2025 season is off to a slow start, but hurricane experts don't expect things to stay quiet. Ocean temperatures are warming more than normally expected in an area of the Atlantic called the "main development region," called that because of its propensity to crank out some of the strongest storms, hurricane specialist Michael Lowry wrote in a July 22 post on his Substack blog. Sea surface temperatures have risen sharply in the region in July. Warmer seas can help fuel any potential storm systems that form in the region. How do hurricanes form? An inside look at the birth and power of ferocious storms Lowry credits the current warming in the Atlantic to a weakening of the Bermuda High, a pattern of high pressure that expands and shrinks over the western Atlantic and heavily influences hurricane movement. "After some of the strongest trade winds on record to start the year, and the strongest June trade winds since 1990," trade winds in July have been the weakest since at least 1979, wrote Lowry, a hurricane center veteran and now a specialist at WPLG 10 in Miami. Other signals including a periodic oscillation over the ocean that influences hurricane activity and a shift in the monsoon winds in North Africa also signal a potential increase in activity.
