Atlantic Hurricane Outlook – July 9, 2025: Calm Seas Persist Amid Seasonal Build

The Atlantic remains quiet today, with no active storms and no development expected. But record-warm waters and shifting atmospheric patterns suggest that tropical activity could ramp up soon.

Mid-July typically signals more tropical activity—but today, the Atlantic remains unusually quiet. According to the latest NHC updates, no tropical cyclones are present, with no expected development over the next seven days. Despite the current calm, strong indicators suggest the season’s intensity is primed to rise.

NOAA NHC Daily Hurricane Update - July 9, 2025

Atlantic Basin: All Clear for Now

  • No active systems in the Atlantic, Caribbean, or Gulf

  • NHC forecast maintains zero development chances across the basin

  • This lull is rare for July and may end soon as heat and moisture build

Seasonal Outlook: Above-Normal Conditions Ahead

  • CSU’s July update continues to forecast an above-average season:
    ~17 named storms, including ~9 hurricanes and ~4 major hurricanes .

  • NOAA similarly predicts 13–19 named storms, with a 60% chance of a busier-than-average season.

Sea Surface Temperatures: High Heat Levels

  • Atlantic SSTs remain well above normal—2–4°F above average—in the Gulf, Caribbean, and MDR

  • These elevated temperatures continue to provide plenty of energy for storm formation in the weeks ahead

Atmospheric Conditions: Secondary Barriers Easing

  • Wind shear remains moderate-to-high, particularly in the eastern Atlantic—temporarily limiting development

  • Saharan Air Layer (SAL) and occasional dry mid-level air still suppress convection but are expected to diminish

  • Moisture is steadily increasing, with abundant humidity projected across storm-prone regions

What to Watch Next

  • Upcoming Infrared and visible satellite loops for signs of organization

  • Shifts in wind shear over the Gulf and Caribbean

  • Any African easterly waves gaining moisture and structure

Early July Trends

  • Only one named storm (Chantal) has formed so far, but it remained weak and quickly dissipated 

  • History shows many July systems originate in the Gulf, Caribbean, or off the Southeast U.S. coast

Outlook: Active Patterns Brewing

  • While quiet now, the combination of warm SSTs, moist air, and weakening shear/SAL signals a rising likelihood of Atlantic development

  • Hurricane Season Peak is still ahead—August through October—but increased vigilance is essential now
