Atlantic Hurricane Outlook – June 18, 2025: Tropics Stay Quiet as Pacific Storms Steer Focus

The Atlantic remains storm-free on June 18, with no tropical systems expected over the next 7 days. But warming ocean temps and an active Pacific raise long-range concerns.

The Atlantic basin remains calm today, with no active tropical cyclones and no systems being monitored for development in the National Hurricane Center’s latest 2 AM EDT outlook. This early-season quiet continues, but shifting global patterns—warm oceans, dust, and Pacific activity—are fueling a cautious watchfulness.

Daily Hurricane Update from NOAA and NHC for June 18, 2025

Atlantic Basin: Clear, But Keep Watching

No Atlantic systems are active, and the seven-day forecast shows no tropical development expected this week . While mid-June calm is common, meteorologists note stronger global volatility due to cross-basin interactions and shifting climate signals.

Pacific Spotlight: Tropical Storm Erick on the Rise

Wind Speed Probability Tropical Storm Erick

All eyes are on the Eastern Pacific, where Tropical Storm Erick is rapidly strengthening—forecast to become the season’s first Pacific hurricane. Though Erick poses no threat to U.S. shores, it demonstrates the early-season dynamism that Atlantic may encounter soon.

Sea Surface Temperatures: Heat Builds Beneath the Calm

  • Gulf & Western Caribbean: SSTs remain well above average (84–88 °F), providing potential fuel.

  • Main Development Region (MDR): Water temperatures are warming and trending warmer than early June norms, laying a foundation for development later in the season.

Saharan Dust & Atmospheric Inhibitors


Wind Shear Courtesy of https://tropic.ssec.wisc.edu/

  • A large plume of Saharan dust continues to stretch across the Atlantic and into the Caribbean and Southeast U.S., suppressing tropical formation and degrading air quality.

  • This dust layer, combined with moderate wind shear, continues to inhibit tropical systems.

Thunderstorm Activity: Summer Rhythm

  • Florida & Southeast U.S.: Expect standard afternoon thunderstorms, born from daytime heating—not tropical phenomena.

  • Caribbean & Atlantic: Skies remain clear, with no clusters or organic storms forming.

  • Air Quality Alert: Sensitive groups should note haze and dust over the Southeast.

Florida Forecast (June 18)

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

  • Humidity: High, with muggy conditions

  • Rain: Isolated to scattered afternoon storms

  • Visibility: Reduced by dust haze in some regions

  • Winds: Light, stronger near storms

Prep Tip of the Day: Monitor Dust and Air Quality

  • Minimize outdoor exposure if you’re sensitive to dust

  • Clean or replace filters in HVAC systems

  • Keep monitoring dust levels through local air-quality alerts

  • Continue hurricane planning while skies are calm

Looking Ahead: Still Quiet, But Global Trends Are Stirring

No Atlantic storms are expected this week. However:

  • SSTs remain elevated

  • Wind shear may ease gradually

  • Saharan dust may shift or thin

  • Eastern Pacific activity—like Erick—offers insight into potential future Atlantic behavior

Use this calm period to prepare. Tomorrow could bring the first tropical ripple, so stay connected to Cat5Prep for ongoing updates.

Atlantic Hurricane Outlook – June 10, 2025: Quiet Continues, But Observers Stay Alert

No storms in sight, but sea surface temperatures continue to rise and wind shear is gradually easing—signs that the quiet start to the 2025 hurricane season may not last.

The tenth day of the 2025 Atlantic hurricane season opens with calm skies and no immediate threats. The latest update from the National Hurricane Center (NHC) confirms no active systems and no expected tropical cyclone formation over the next seven days. Early June often starts this way, but with sea surface temperatures climbing and atmospheric factors slowly shifting, vigilance remains important.

Daily Hurricane Update June 10, 2025 from NOAA with 7 Day Outlook

Atlantic Basin: No Systems in Sight

  • No active tropical cyclones

  • No areas of interest

  • No development anticipated within 7 days

This outlook aligns with the expected early-season lull, but conditions are steadily changing.

Sea Surface Temperatures: Warming Trend Continues

  • Gulf of Mexico & Western Caribbean: Still in the low to mid‑80s °F (around 27–29 °C), ideal for fueling storms when other factors permit

  • Main Development Region (MDR): Running warmer than average for early June—enough to support development later this month

These warm waters are critical as the season progresses.

Atmospheric Conditions: Mixed Signals

  • Wind Shear: Moderate to high across much of the basin, particularly within the western Caribbean and central Atlantic—limiting today’s storm potential

  • Moisture: Mid-level moisture appears to be on the rise, which could support future thunderstorm activity

Saharan Air Layer: A Dry Deterrent

  • A robust plume of Saharan dust continues to suppress tropical wave development across the eastern Atlantic and MDR

  • This dry layer is expected to ease by late June, removing one of the key early-season inhibitors

Thunderstorm Activity: Routine, Not Tropical

  • Florida & Southeastern U.S.: Expect isolated afternoon storms typical for June

  • Western Caribbean: A few disorganized showers and storms—no rotation or organization evident

  • Atlantic Ocean: Quiet, with no tropical wave activity currently observed

Florida Forecast (Statewide)

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

  • Humidity: Moderate to high—classic muggy comfort

  • Rain: Scattered afternoon/evening showers typical of early summer

  • Winds: Light and variable

Prep Tip of the Day: Check Evacuation Zones

With time on your side:

  1. Confirm your evacuation zone and review the planned evacuation route

  2. Update your family emergency contact lists

  3. Ensure your NOAA weather radio and mobile alert settings are active

  4. Keep local emergency management contacts accessible

Looking Ahead: Still Quiet, But Watch for Change

While no tropical development is expected this week, underlying conditions are subtly shifting:

  • Warm ocean waters persist

  • Atmospheric wind shear is forecast to gradually decrease

  • Moisture levels are on the rise

  • Saharan dust is weakening, removing suppression barriers

Early hurricane season often starts quietly—but conditions can change fast. Stay tuned to Cat5Prep.com for daily updates.
