Tropical Storm Dexter: Live Tracker as Chances of Forming Quadruple
Newsweek AI is in beta. Translations may contain inaccuracies—please refer to the original content.
Chances that Tropical Storm Dexter will form within the next 48 hours have quadrupled since a forecast issued by the National Hurricane Center (NHC) on Monday.
As the storm takes shape, Florida can expect heavy rainfall. Even if the storm doesn't form, the heavy rain will move across the Sunshine State and into the Gulf, where it will impact coastal states later this week.
As of Tuesday around noon Eastern time, AccuWeather Lead Hurricane Expert Alex DaSilva told Newsweek the storm was moving inland and bringing "really, really heavy rain."
Why It Matters
The Atlantic hurricane season began on June 1. The last storm to form was Tropical Storm Chantal earlier this month.
NHC meteorologists are currently monitoring a low-pressure system east of Florida that has a 40 percent chance of becoming tropical within the next 48 hours. Should it form, the storm will be named Dexter.
The development comes as meteorologists predicted an above-average hurricane season this year for the Atlantic.
A map from the NHC shows there is a 40 percent chance Tropical Storm Dexter will form within 48 hours.

What To Know
On Monday, the NHC said there was a 10 percent chance the storm would form within the next two days. By that afternoon, the chance had increased to 20 percent.
By Tuesday morning, the chances increased again to 40 percent. The NHC cautioned that even if it doesn't form, Florida can expect some impact, such as heavy rain and flash floods.
Weather Radar
Animated weather maps from windy.com showed a cluster of storms in Florida near the state's Atlantic coast.
As of Tuesday afternoon, the storms have not yet organized into a tropical system. DaSilva told Newsweek he doubts the storm will strengthen while it moves over land.
Wind
Despite the lack of organization, some strong winds are still expected with the storms. Sustained winds of around 25 mph were recorded in the Atlantic Ocean to the east of Florida. Winds were gusting around 36 mph.
A tropical storm has sustained winds between 39 and 73 mph. A tropical storm becomes a Category 1 hurricane once sustained winds hit 74 mph.
Rain
Meteorologists warned that the biggest impact from the storm will be heavy rain. Over the next three days, windy.com forecasts that Central Florida could receive around 2 inches of rain.
The highest rainfall amounts will be coastal Louisiana, which could receive up to 4 inches.
What People Are Saying
The NHC, in a forecast: "This system is forecast to move westward across the Florida Peninsula today and then reach the northeastern Gulf by Wednesday. Environmental conditions appear generally favorable for additional development, and a tropical depression could form while the system moves across the northeastern and north-central Gulf."
AccuWeather Lead Hurricane Expert Alex DaSilva, in an AccuWeather report: "Heavy downpours are expected to continue across much of the Florida Peninsula through Tuesday night. Thunderstorms, infused with tropical moisture, could produce more than 4 inches of rain."
What Happens Next
Heavy rain is expected to cause flash flooding in Florida through mid-week, the NHC forecast said. Then, flash flooding and heavy rain will hit the Gulf Coast later this week.

National Hurricane Center now watching 3 waves in Atlantic. Heat, storms expected Tuesday
The latest maybe-threat in the tropics is currently no threat at all. The National Hurricane Center has been watching a disorganized area of showers and thunderstorms in the Atlantic associated with an area of low pressure hundreds of miles east-southeast of the Lesser Antilles, but the latest July 22 update gives it zero chance of further development. "Environmental conditions are becoming increasingly unfavorable as the wave moves west-northwestward at around 15 mph, and further development is no longer anticipated," Hurricane Specialist Philippe Papin said in the update. Most of the state can expect to see some rain and thunderstorms today from it, though, along with moisture from the Atlantic, National Weather Service forecasters said. AccuWeather forecasters are watching the low-pressure system as well as an area of the Gulf of America where a slow-moving round of heavy rain and thunderstorms may develop this week, and an area extending from Texas to the Carolina coast with a low chance of tropical development. The NHC is also tracking another tropical wave that just left the coast of Africa, making that three to watch in the Atlantic. ➤ 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.

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? National Hurricane Center map: See what forecasters watching now Systems currently being monitored by the National Hurricane Center include: Why does NHC say 'tropical cyclone' on its maps instead of hurricane or tropical storm? 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.

Wipha lashes Vietnam with strong winds and heavy rain
Tropical Storm Wipha made has landfall in northern Vietnam, bringing strong winds and heavy rain to parts of the country's north and central regions. The storm came ashore with sustained winds of 64-102km/h and gusts up to 138km/h, according to local weather officials. After landfall, Wipha began moving southwest. Wipha was classified as a typhoon on Monday while over open water, but weakened overnight and was downgraded to a tropical storm before reaching land. The storm knocked out power in parts of Hung Yen Province, east of Hanoi. Residents rushed to petrol stations to buy fuel for generators, state media reported. The streets of Hanoi were nearly empty as the storm moved inland. Most businesses were closed and the city government has advised residents to stay home and evacuate buildings that are unstable or in flood-prone areas. "If the storm is serious, people shouldn't go out anyway because it would be dangerous on the road and there is also a chance of flooding," said Minh Doan, a taxi driver in Hanoi. Flights were cancelled across northern Vietnam, and airports in the port city of Hai Phong and Quang Ninh province were closed. Nearly 150,000ha of aquaculture farms and more than 20,000 floating fish cages are at risk from flooding and strong winds, according to state media. Vietnam has warned of flooding as heavy rain from Storm Wipha moves inland. At least three people died in the Philippines after Wipha struck the north of the country without making landfall last Friday. More than 80,000 people remain in emergency shelters after floods, landslides and tidal surges over the weekend. Most government offices and schools in Manila and 10 provinces were shut on Tuesday due to widespread flooding from heavy monsoon rains, and troops evacuated residents from villages swamped by knee- to waist-deep water while the coast guard deployed buses and boats to assist stranded commuters. with AP
