Tropical Storm Gabrielle forms, ending the Atlantic’s strange drought. It could become a hurricane

Tropical Storm Gabrielle has officially formed in the central Atlantic Ocean, marking a significant development in what has been an unusually quiet period for storms during a typically active hurricane season. This newly formed storm is a reminder of the dynamic nature of the Atlantic and its potential for sudden change.

### Background on Gabrielle’s Formation

Gabrielle came into existence on Wednesday morning, located more than 1,000 miles from the northern Leeward Islands. Initial assessments report sustained winds of 45 mph. The National Hurricane Center (NHC) projects that Gabrielle could strengthen into a hurricane by Saturday as it moves in a north-northwest direction. It is essential to note that while water temperatures are conducive to storm intensification, atmospheric conditions may pose challenges to Gabrielle’s growth in the short term.

### Impacts on the United States

Currently, Gabrielle is expected to avoid direct impacts on the continental United States. However, the storm may create higher surf conditions along the East Coast in the following week. As it progresses, it will likely generate hazardous rip currents that could pose a risk to swimmers and beachgoers.

### The Drought Before Gabrielle

Gabrielle’s formation marks the end of a notable stretch of inactivity in the Atlantic. According to Dr. Phil Klotzbach, a prominent hurricane researcher at Colorado State University, this is only the second instance since 1950 where the Atlantic remained storm-free from August 29 to September 16. The only other similar occurrence was during a quiet period after Hurricane Andrew struck the U.S. in 1992.

The unusual drought in storm activity can be attributed to several atmospheric phenomena that have inhibited tropical development. Stronger-than-average wind shear and dry air have played roles in stifling storm formation throughout the peak of the hurricane season, which typically runs from mid-August to mid-October.

### Forecasting Gabrielle’s Path

As it stands, high pressure to the north of Gabrielle will largely dictate its movement over the next few days. This system is expected to carry the storm on a west-northwest trajectory, steering it north of the eastern Caribbean islands by the weekend. Yet, as the high pressure begins to weaken, it may alter the course of the storm, ultimately determining its proximity to Bermuda in the subsequent week.

### Emerging Storms in the Atlantic

Simultaneously, another area of concern has emerged from Africa, with showers and thunderstorms developing behind Gabrielle. This system could transition into a tropical depression or storm, but the NHC has indicated no immediate threat to land for at least the next week. This is, notably, two weeks later than the typical timeline for the seventh tropical storm of the season, as one generally forms by September 3.

### Understanding the Current Climate Conditions

The current warm sea surface temperatures across the Atlantic are ideal for storm generation—serving as “jet fuel” for potential tropical systems. However, despite this favorable oceanic condition, atmospheric inhibiting factors have limited storm growth this season. Dry, stable air in the tropical Atlantic is one such deterrent, as it hampers storm systems’ ability to organize and develop robustly.

Historically, September has been one of the busiest months for tropical activity, capitalizing on favorable atmospheric and oceanic interactions. Unfortunately, this year has diverged from the norm, with only six tropical storms developed by August, among which only one—Hurricane Erin—reached hurricane status.

### Conclusion: The Future of Gabrielle

As of now, Gabrielle stands as a significant development in the Atlantic, poised to become a hurricane as it navigates through warmer waters. While residents in the U.S. may not face immediate dangers, it is crucial for those in the eastern Caribbean to remain vigilant due to anticipated high surf and rip currents. Moreover, the looming possibility of additional storms emerging from Africa reinforces the unpredictability of the season.

This year’s unusual inactivity followed by the rapid development of Gabrielle exemplifies the complexity of weather patterns influenced by climate change. Keeping a keen eye on Gabrielle’s progress and understanding the broader atmospheric conditions can help residents remain informed and prepared as the season unfolds. As hurricane season continues, stakeholders from coastal communities to meteorologists will monitor developments closely, ensuring public safety and awareness.
