Is the Atlantic hurricane season about to pick up after a lull?
This weekend, the hurricane scene is calm, with the National Hurricane Center noting that there are currently no named storms in the Atlantic Basin—a rarity for Labor Day.
However, this quiet period might not last. AccuWeather indicates that tropical activity is starting to “ramp back up” as we reach the middle of the 2024 hurricane season. By September, the Atlantic’s ocean temperatures have warmed sufficiently, increasing the likelihood of thunderstorms and storm formation, as forecasters point out.
This time of year usually provides ideal conditions for the creation of tropical depressions, storms, and hurricanes, and Labor Day weekend is often one of the most active periods for severe weather. Despite this, there are currently no named storms.
According to AccuWeather’s Lead Hurricane Expert, Alex DaSilva, “Slightly higher than average wind shear across the Atlantic has helped to limit tropical development.”
If no named storms develop in the Atlantic by Monday, it would mark the first time in 27 years that there hasn’t been a single named tropical storm during the period from August 21 to September 2.
Heavy rain and flooding expected for Texas and Louisiana
A low-pressure system in the Northwestern Gulf of Mexico is causing showers and thunderstorms off the Texas and Louisiana coasts. This system is projected to stay near the coast for several days but is not anticipated to become a named storm.
The Hurricane Center cautioned that regardless of any development, heavy rainfall could lead to flash flooding in parts of coastal Louisiana and the upper Texas coast in the coming days.

Tropical depression may form by the end of the week
A tropical wave situated to the east of the Lesser Antilles has the potential to become a tropical depression later in the week as it progresses westward, according to the center’s Sunday update. The system is expected to reach the Lesser Antilles on Monday and continue across the Caribbean Sea. Conditions later in the week are expected to be more favorable for development, possibly leading to the formation of a tropical depression. This system may bring strong winds and heavy rain to parts of the Lesser Antilles on Monday.
The hurricane center estimates a 40% chance for this system to develop over the next week. The next storm will be named Francine.
System moving toward the Americas from Africa
A tropical wave currently over western Africa is expected to move out to sea on Monday. Conditions may permit some slow development as it gradually heads westward or west-northwest in the eastern tropical Atlantic Ocean, according to weather services. However, the effects on the U.S. when it arrives in a few days remain uncertain.
