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.
