Hurricane center keeps track of 2 Atlantic systems
ORLANDO, Fla. - The National Hurricane Center on Friday continued to keep track of two systems in the Atlantic that could become the season's next tropical depression or storm. As of the NHC's 8 a.m. tropical advisory, the closest was a weak area of low pressure located a couple hundred miles offshore of North Carolina with a few disorganized showers and thunderstorms. "Development of this system, if any, is expected to be slow to occur over the next day or two while it moves northeastward at 10 to 15 mph. The low is likely to merge with a front over the weekend, ending its chances for tropical or subtropical development," forecasters said. The NHC gave it a 10% chance to develop in the next two to seven days. Farther east, though, a tropical wave in the central Atlantic had minimal shower activity. "Development of this system appears unlikely during the next day or two due to surrounding dry air, but environmental conditions are forecast to become more conducive in a few days," forecasters said. "A tropical depression could form during the early or middle part of next week while the system moves northwestward to northward across the central tropical and subtropical Atlantic." The NHC gave it a 50% chance to develop in the next seven days. The next names on the 2025 Atlantic hurricane season list are Erin and Fernand. The season so far has produced four tropical storms with the most recent, Tropical Storm Dexter, having moved through the North Atlantic this week where it was no threat to land. The National Oceanic and Atmospheric Administration this week updated its season forecast now calling for 13-18 named storms for the year, of which five to nine would grow into hurricanes. Two to five of those would develop into major hurricanes of Category 3 strength or higher. The height of hurricane season runs from mid-August into October. The entire six-month season runs June 1 to Nov. 30. -------------- Copyright (C) 2025, Tribune Content Agency, LLC. Portions copyrighted by the respective providers.

Hurricane center keeps tracking 2 Atlantic systems while TS Dexter becoming extratropical
The National Hurricane Center on Thursday forecast Tropical Storm Dexter to become extratropical, but continued to keep track of two developing Atlantic systems that could become the season's next tropical depression or storm. As of the NHC's 8 a.m. tropical advisory, closer to the the U.S. but moving away was a weak area of low pressure a couple hundred miles off the coast of the southeastern United States producing limited shower and thunderstorm activity. 'Some slow tropical or subtropical development is possible over the weekend while the system moves northward to northeastward, remaining well off the east coast of the United States,' forecasters said. 'By early next week, the low is expected to become extratropical, ending its chances for tropical development.' The NHC gave the system a 30% chance to develop in the next seven days. Farther east, though, a tropical wave that was headed to the central Atlantic also had disorganized shower activity. 'Environmental conditions are forecast to become more conducive for gradual development in a few days, and a tropical depression could form late this weekend or early next week while the system moves west-northwestward to northwestward across the central tropical and subtropical Atlantic,' forecasters said. The NHC gave it a 10% chance to develop in the next two days and 60% in the next seven. The next names on the 2025 Atlantic hurricane season list are Erin and Fernand. The season's fourth named storm continued to churn in the Atlantic as well. Tropical Storm Dexter, which formed in the Atlantic on Sunday night, remained no threat to land. As of 5 a.m. Thursday, the center of Dexter was located about 425 miles south of Cape Race, Newfoundland moving east-northeast at 168 mph with maximum sustained winds that had grown to 50 mph. Tropical-storm-force winds extend out 175 miles. 'An east-northeast to northeast motion is expected during the next couple of days,' forecasters said, 'Dexter is expected to strengthen as an extratropical low later today through Friday. The cyclone is forecast to weaken beginning Friday night and Saturday.' Dexter became the fourth named storm following tropical storms Andrea, Barry and Chantal. Before the start of hurricane season, the National Oceanic and Atmospheric Administration had forecast an expected 13 to 19 named storms for the year, of which 6 to 10 would grow into hurricanes. Three to five of those would develop into major hurricanes of Category 3 strength or higher. The height of hurricane season runs from mid-August into October. The entire six-month season runs June 1 to Nov. 30.

National Hurricane Center tracking Tropical Storm Dexter, 2 other systems. Where are they going?
Tropical activity picked up in the Atlantic basin over the weekend. Tropical Storm Dexter formed off the coast of North Carolina Sunday night, Aug. 3 but is not considered a threat to Florida or the U.S. ➤ Track all active storms ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location Dexter formed almost two weeks earlier than the historical average for the fourth named storm of the Atlantic hurricane season. The average date for the fourth storm is Aug. 15. Historically, the first hurricane develops in the Atlantic Aug. 11. The National Hurricane Center is also tracking two other systems showing some potential for development: one off the Florida and the other a tropical wave moving off the coast of Africa. The tropical wave in the central Atlantic could become a tropical depression later this week, according to the National Hurricane Center. Next up will be Erin and Fernand. Here's the latest advisory from the National Hurricane Center as of 2 p.m., Aug. 4: Where is Tropical Storm Dexter and where is it going? Location: 255 miles northwest of Bermuda Maximum sustained winds: 45 mph Movement: east-northeast at 12 mph Pressure: 1,002 mb Next advisory: 11 a.m. ➤ Tropical Storm Dexter forms off US coast. See latest spaghetti models, any Florida impacts Spaghetti models for Tropical Storm Dexter 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 Dexter Will Dexter become a hurricane? Will it threaten Florida? Dexter is not expected to impact Florida or the U.S. as it moves northeast into the northern Atlantic, according to the National Hurricane Center. While some slight strengthening is possible, Dexter is expected to remain a tropical storm as it encounters wind shear and dry air. What tropical waves, disturbances are in Atlantic basin now? How likely are they to strengthen? First tropical wave: A broad area of low pressure is forecast to develop in a day or two several hundred miles off the coast of the southeastern United States. Some gradual development of this system is possible duringthe middle or latter portion of this week as the system moves slowly westward to northwestward. Formation chance through 48 hours: low, near 0 percent. Formation chance through seven days: low, 30 percent. Second tropical wave: A tropical wave located just off the west coast of Africa is currently producing minimal shower activity. As the wave moves west-northwestward over the next few days, environmental conditions are forecast to become favorable for gradual development. A tropical depression could form by the latter portion of this week as the system continues moving generally west-northwestward across the central tropical Atlantic. Formation chance through 48 hours: low, near 0 percent. Formation chance through seven days: medium, 50 percent. 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 Dexter, tropical waves out there? Tropical Storm Dexter is not expected to impact Florida or the U.S. as it moves into the northern Atlantic. It's too early at this time to determine if there will be any impact to Florida or the U.S. from the tropical waves. ➤ Excessive rainfall forecast Forecasters urge all residents to keep an eye on the tropics and to always be prepared. Buy hurricane supplies tax free in Florida Officials repeatedly warn Florida residents the time to prepare for a hurricane is before a storm is approaching, when shelves are full stocked and you aren't battling crowds all rushing to the store at the same time. In prior years, Florida residents took advantage of one or two sales tax holidays to save money on hurricane supplies ranging from batteries to generators. On Aug. 1, certain supplies became permanently tax free in Florida. ➤ See list of emergency supplies you can now buy tax free Florida weather radar for Aug. 4, 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.

National Hurricane Center tracking 3 systems. Will we see Erin and Fernand soon?
August is living up to its reputation as the month when activity in the tropics picks up. Tropical Storm Dexter is strengthening in the northern Atlantic, and forecasters are keeping a close eye on two systems that could become tropical depressions later this week or over the weekend, according to the latest advisory from the National Hurricane Center. ➤ Track all active storms ➤ Weather alerts via text: Sign up to get updates about current storms and weather events by location One of the disturbances is located a few hundred miles off Florida and the southeastern coast of the United States. It has a 40% chance for development over the next seven days. Chances have picked up for development of the tropical wave farther east in the Atlantic. It now has a 60% chance for development over the next seven days. Farther north, Tropical Storm Dexter has strengthened and could approach hurricane strength over the next 48 hours before dissipating later this week. It's expected to bring an increased risk for increased surf and a medium risk for rip currents to Florida and the Atlantic coast. The next named storms of the Atlantic hurricane season will be Erin and Fernand. Here's the latest advisory from the National Hurricane Center as of 8 a.m., Aug. 6: Where is Tropical Storm Dexter and where is it going? Location: 405 miles south-southeast of Halifax, Nova Scotia Maximum sustained winds: 45 mph Movement: east-northeast at 13 mph Pressure: 1,003 mb Next advisory: 11 a.m. ➤ Tropical Storm Dexter: See latest spaghetti models, any Florida impacts Spaghetti models for Tropical Storm Dexter 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 Dexter Will Dexter become a hurricane? Will it threaten Florida? Some models are showing Dexter does have a potential to become a hurricane before it dissipates later this week. The National Hurricane Center is forecasting maximum sustained winds will reach 70 mph within the next 48 hours, just short of the 74 mph needed to be classified as a hurricane. While far from Florida, Dexter is expected to bring higher surf conditions of 2 to 4 feet, along with a moderate risk for rip currents, according to the National Weather Service Melbourne. ➤ How often has Florida been impacted, threatened by August hurricanes? We took a look back "Dexter, along with developing easterly breezes around high pressure near the Northeast states, will create locally rough surf and periodic strong rip currents along the Atlantic coast beaches this week from Florida to Massachusetts," AccuWeather Lead Hurricane Expert Alex DaSilva said. What tropical waves, disturbances are in Atlantic basin now? How likely are they to strengthen? First tropical wave: A weak area of low pressure has formed from a surface trough, several hundred miles off the coast of the southeastern United States. However, this system is currently producing only limited shower and thunderstorm activity and development is likely to be slow to occur during the next few days. Thereafter, environmental conditions could become a little more conducive for development. A tropical depression could still form by this weekend as the low initially drifts westward before turning northward to northeastwardby the weekend. Formation chance through 48 hours: low, 10 percent. Formation chance through seven days: medium, 40 percent. Second tropical wave: A tropical wave over the eastern tropical Atlantic continues to produce a broad area of disorganized showers and thunderstorms. Environmental conditions are forecast to be conducive for gradual development during the next few days, and a tropical depression could form late this week or over the weekend as the system moves generally west-northwestward to northwestward across the central tropical and subtropical Atlantic. Formation chance through 48 hours: low, 20 percent. Formation chance through seven days: medium, 60 percent. How could disturbance off southeast coast affect Florida? "This system poses no direct threat to Florida at this time," the Florida Department of Emergency Management said. "However, it could bring elevated rain chances and rip currents along portions of the East Coast later in the week and into the weekend." The system has a limited time for development, although it could become a tropical depression or storm before the end of the week, according to AccuWeather. "Heavy rain is expected across parts of the Southeast this week, regardless of official tropical development because of the old front," said AccuWeather Lead Hurricane Expert Alex DaSilva. Downpours and gusty thunderstorms are possible in the Carolinas. Remember, conditions and forecasts can change rapidly. If the system strengthens into a tropical storm and moves inland, "a more serious flash flood risk may evolve in portions of the Carolinas, Georgia and Virginia," according to AccuWeather. Is there a hurricane coming toward Florida? No. A weak surface disturbance is located several hundred miles off the coast of Florida and the Southeast U.S., producing scattered showers and thunderstorms. An area of low pressure is expected to form from this disturbance over the next day or so, where environmental conditions appear generally favorable for additional development. A tropical depression could form by the latter portion of this week or weekend as the low starts moving slowly westward, but turns more northward by this weekend. There's a 40% chance of development over the next seven days, according to the latest advisory from the National Hurricane Center. 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. What should you do now to prepare for hurricane season? Officials regularly encourage Florida residents to prepare for storms before a hurricane is approaching while shelves are full stocked and you aren't battling crowds all rushing to the store at the same time. "It only takes one storm to make it an impactful year for your community," the National Hurricane Center Miami posted on X. "Hurricane season is a marathon, not a sprint." On Aug. 1, specific hurricane supplies became permanently tax free in Florida, ranging from batteries to generators. ➤ See list of emergency supplies you can now buy tax free Florida weather radar for Aug. 6, 2025 Weather watches and warnings issued in Florida When is the Atlantic hurricane season?

Hurricane center eyes 2 Atlantic systems along with Tropical Storm Dexter
ORLANDO, Fla. - The National Hurricane Center on Wednesday continued to keep track of Tropical Storm Dexter as well as two developing Atlantic systems that could become the season's next tropical depression or storm. As of the NHC's 8 a.m. tropical advisory, the closest system to the U.S. was a weak area of low pressure that had formed from a surface trough several hundred miles off the coast of the southeastern United States. "However, this system is currently producing only limited shower and thunderstorm activity and development is likely to be slow to occur during the next few days," forecasters said. "Thereafter, environmental conditions could become a little more conducive for development. A tropical depression could still form by this weekend as the low initially drifts westward before turning northward to northeastward by the weekend." The NHC gave it a 10% chance to develop in the next two days and 40% in the next seven. Farther east, a tropical wave was headed to the central tropical Atlantic with a broad area of disorganized showers and thunderstorms. "Environmental conditions are forecast to be conducive for gradual development during the next few days, and a tropical depression could form late this week or over the weekend as the system moves generally west-northwestward to northwestward across the central tropical and subtropical Atlantic," forecasters said, The NHC gave it a 20% chance to develop in the next two days and 60% in the next seven. The next names on the 2025 Atlantic hurricane season list are Erin and Fernand. The season's fourth named storm continued to churn in the Atlantic as well. Tropical Storm Dexter, which formed in the Atlantic on Sunday night, remained no threat to land. As of 5 a.m. Wednesday, the center of Dexter was located about 665 miles south-southeast of Halifax, Nova Scotia moving east-northeast at 13 mph with maximum sustained winds that had grown to 45 mph. Tropical-storm-force winds extend out 90 miles. "This motion is expected to continue with some increase in forward speed over the next few days," forecasters said. "Strengthening is forecast during the next 48 hours while the system becomes an extratropical cyclone." Dexter became the fourth named storm following tropical storms Andrea, Barry and Chantal. Before the start of hurricane season, the National Oceanic and Atmospheric Administration had forecast an expected 13 to 19 named storms for the year, of which 6 to 10 would grow into hurricanes. Three to five of those would develop into major hurricanes of Category 3 strength or higher. The height of hurricane season runs from mid-August into October. The entire six-month season runs June 1 to Nov. 30. ----------------- Copyright (C) 2025, Tribune Content Agency, LLC. Portions copyrighted by the respective providers.
