Atlantic Hurricane Outlook – June 5, 2025: A Weak Low, a Wet Southeast, and a Watchful Eye

June 5 brings continued calm in the Atlantic, with no named storms and no areas of concern. But warm sea surface temperatures and slowly shifting atmospheric conditions suggest more activity may be on the way later this month.

The fifth day of the 2025 Atlantic hurricane season begins with calm skies and no tropical activity on the horizon. While this early June quiet is typical, forecasters are closely watching for subtle atmospheric shifts that may usher in increased activity later in the month. Now is the perfect time to double-check your emergency plans while the weather remains cooperative.

Daily Hurricane Update for day of June 5, 2025

Atlantic Basin: No Immediate Concerns

As of the latest National Hurricane Center (NHC) update (8 PM EDT June 4 or the upcoming 2 AM EDT June 5 outlook):

  • No active tropical cyclones

  • No areas of interest under investigation

  • No development expected within the next 7 days

This quiet pattern aligns with the early season lull seen in most years before conditions ramp up later in June and July.

Sea Surface Temperatures: Warming Trend Continues

Ocean heat—an essential ingredient for tropical storm formation—is building across the Atlantic:

  • Gulf of America (Mexico): Widespread low to mid-80s°F (28–30°C), running above average

  • Western Caribbean: Seasonally warm, primed for potential development in coming weeks

  • Main Development Region (MDR): Temperatures are climbing faster than usual for early June, laying a foundation for future storms

Wind Shear & Moisture: Still Mixed, Slowly Improving

Atmospheric conditions aren’t yet fully supportive of tropical formation, but change is underway:

  • Wind Shear: Still moderate to high in the western Caribbean and central Atlantic—strong enough to disrupt organization. Long-range models show a gradual easing expected later in June

  • Moisture: Mid- and lower-atmosphere humidity is rising in the Gulf and Caribbean, hinting at increasing thunderstorm potential

Saharan Air Layer: Strong, But Temporary Barrier

The Saharan Air Layer (SAL) remains a major suppressing force across the tropical Atlantic:

  • Dry, dusty air and associated wind shear prevent tropical waves from organizing

  • This layer is expected to weaken by mid-to-late June, removing a key obstacle to development

Thunderstorm Activity: Typical Early Summer Patterns

No tropical cyclones—but thunderstorm activity continues in familiar places:

  • Florida: Scattered afternoon storms expected from daytime heating

  • Western Caribbean: Some disorganized convection is present but lacks structure

  • Off the U.S. East Coast: No significant organized convection at this time

Florida Forecast – Early Summer Vibes Across the Peninsula

Expect a classic early summer day throughout Florida:

  • Highs: Upper 80s to low 90s°F (31–33°C) statewide

  • Humidity: Elevated levels bringing a muggy, tropical feel all day

  • Rain: Scattered afternoon thunderstorms likely, mostly brief and localized

  • Winds: Light and variable, with gentle breezes in many areas

Stay hydrated and be prepared for brief showers if you’re out and about this afternoon!

Prep Tip of the Day: Verify Emergency Contact Information

Use this calm stretch to get communication-ready:

Looking Ahead: Calm Now, But Stay Ready

No development is expected in the coming week—but the groundwork is being laid:

  • Warm waters across the basin

  • Easing wind shear on the horizon

  • Moisture and instability beginning to rise

The tropics may be quiet today, but the story of the 2025 hurricane season is just beginning. Stay informed, stay ready—and check back tomorrow for the next Cat5Prep.com update.

Atlantic Hurricane Outlook – June 2, 2025: A Quiet Morning, But Don’t Get Comfortable

June 2, 2025 Atlantic hurricane update: Calm skies for now, but unusually warm sea surface temperatures and shifting atmospheric conditions could spark activity later this month. Stay prepared with the latest forecasts and safety tips.

The second day of the 2025 Atlantic hurricane season begins under calm skies, but seasoned forecasters know better than to be lulled by the stillness. With sea temperatures running hot and atmospheric patterns shifting toward favorability, this quiet start may not last long.

Atlantic Basin: All Clear—For Now

As of this morning’s update from the National Hurricane Center (NHC), there are no active tropical cyclones, no areas of interest, and no tropical development expected over the next seven days.

This early-season lull is common in the first half of June, but warm waters and waning atmospheric inhibitors are quietly setting the stage for activity later this month.

Ocean Heat: The Hidden Fuel Source

Sea surface temperatures (SSTs) across the Atlantic basin are unusually high for this time of year—creating the potential for rapid storm intensification when development does occur:

  • Gulf of America (Mexico): Running 2–4°F above average, with large swaths above 86°F (30°C)

  • Caribbean Sea: Above-average temperatures, especially in the western basin

  • Main Development Region (MDR): Continuing to trend hot

Warm water is the engine that powers tropical cyclones, and the basin is already running well above operating temperature.

ENSO Status: La Nada Means No Safety Net

The El Niño–Southern Oscillation (ENSO) remains in a neutral phase, a state meteorologists often refer to as "La Nada."

  • El Niño has ended, removing the high wind shear that often suppresses Atlantic hurricanes

  • La Niña has not yet begun, but conditions may be trending in that direction later this summer

  • Neutral ENSO removes large-scale inhibitors, allowing the Atlantic to operate unchecked

Historically, neutral ENSO years correlate with average to above-average tropical storm activity.

Saharan Air Layer: Dust Still Offers a Buffer—for Now

The Saharan Air Layer (SAL) continues to stretch across the tropical Atlantic, providing a temporary shield against storm formation:

  • Introduces dry, stable air into the atmosphere

  • Inhibits convection and cloud development

  • Increases wind shear in the central Atlantic

The SAL typically weakens by late June, making it easier for tropical waves to grow and organize.

Florida Forecast: A Summer Day with a Side of Humidity

Today’s conditions across Florida reflect typical early-June weather:

  • North Florida: Highs in the upper 80s, low humidity, and mostly sunny skies

  • Central Florida: Highs around 90°F, building humidity, and isolated afternoon storms

  • South Florida: Warm and muggy with highs in the mid-80s and a greater chance of scattered storms after 2 PM

It’s a classic Florida day—but the kind that often precedes the real tropical drama in July and August.

Prep Tips: Take Advantage of the Calm

With no storms on the map, today is a perfect day to prepare:

Looking Ahead: Eyes on the Tropics

We remain in a short-term window of calm, but all indicators suggest that activity will ramp up in the coming weeks. Record-breaking sea surface temperatures and favorable upper-atmospheric trends point to early-season development potential later in June.
