South Florida, FL – The recent flooding rains in South Florida may seem like an inconvenience, but they are playing a critical role in steering hurricanes away from the region.
Over the past few weeks, a shift in atmospheric conditions has caused west-to-east winds to carry daily thunderstorms from the Everglades toward the east coast, bringing heavy rainfall to Miami and Fort Lauderdale.
While this wetter weather is providing relief from earlier drought conditions, experts warn that this pattern likely won’t last throughout hurricane season.
After an unusually dry start to the rainy season, South Florida is now experiencing a reversal that is temporarily keeping hurricane threats at bay. However, as atmospheric patterns evolve over the coming weeks, residents should remain vigilant as conditions become increasingly favorable for storm development.
The Role of Steering Currents in South Florida’s Weather
The past dry spell from mid-May through July was largely influenced by the position and strength of the Bermuda High, a semipersistent high-pressure system known for its clockwise circulation and mostly dry air.
This system shifted eastward over Florida, creating a stable atmosphere and directing afternoon thunderstorms westward away from Miami toward Naples and Fort Myers.
This steering pattern not only exacerbated drought conditions across southeast Florida but also influenced the course of potential hurricanes. A strong Bermuda High generates trade winds across the tropical Atlantic that push storms directly toward Florida, as was the case with the catastrophic Category 5 Hurricane Andrew in 1992, which devastated Miami-Dade.
Current Weather Patterns and Their Impact on Hurricanes
Currently, a significant dip in the jet stream near the U.S. east coast is pushing cold fronts further south than usual. These westerly winds aloft are creating wind shear conditions that typically weaken or inhibit tropical storm formation.
Despite ongoing heavy rains causing widespread flooding — especially during the vulnerable King Tide season — this atmospheric setup is limiting hurricane formation near Florida. This was evident during Major Hurricane Erin (August 2022), which re-curved away from the mainland due to a weakened Bermuda High.

“While the wet weather is inconvenient and flooding may be damaging, especially now with King Tide season, the current atmospheric ‘soupy setup’ is keeping hurricane threats in check and away from Florida,” explained weather expert John Morales.
- West-to-east winds are transporting thunderstorms toward Miami and Fort Lauderdale.
- Strong dip in the jet stream causing increased wind shear and cooler air intrusions.
- Sea surface temperatures remain among the warmest on record, providing potential future energy for storms.
- Bermuda High’s current weakness reduces the risk of storms targeting Florida directly.
Looking Ahead: What Could Change This Pattern?
Experts caution that the protective weather pattern may not last. Long-term forecasts indicate that the jet stream dip will retreat, leading to reduced wind shear and less inhibition of tropical storm development, particularly as September progresses. Coupled with persistently warm Atlantic sea surface temperatures, these factors create a more favorable environment for hurricanes.
Florida’s residents are reminded not to become complacent.
A similar pause in activity last year ended with a powerful back-loaded hurricane season featuring devastating storms like Hurricanes Helene and Milton. This highlights the importance of preparedness as conditions shift.

Key Takeaways for Florida Residents
- Recent heavy rains are temporarily steering hurricanes away from South Florida.
- The Bermuda High’s changing position is a major factor in hurricane paths.
- Jet stream fluctuations and wind shear currently inhibit storm formation near Florida.
- Warm sea surface temperatures mean hurricane risks could rise in late September.
- Preparedness remains crucial despite the current lull in hurricane threats.
