Atlantic Hurricane Outlook – July 13, 2025: Tropics Quiet, Gulf Trough Under Watch

No named storms today, but a low-pressure trough drifting toward the Gulf of Mexico could bring rain and potential tropical development later this week.

The Atlantic basin remains calm today, with no active named storms. However, meteorologists are tracking a low-pressure trough emerging off the Southeast U.S. coast, gradually drifting into the Gulf of Mexico. This system has a low (20%) chance of organizing into a subtropical or tropical system later this week .

Daily Hurricane Update July 13, 2025 - NHC NOAA

Atlantic Overview: Quiet But Evolving

As per the 8 AM EDT NHC Tropical Weather Outlook:

  • No active tropical cyclones across the basin.

  • The Southeast U.S. trough is expected to push into the Gulf by Tuesday.

  • Formation chances: <1% in next 48 hours, ~20% over 7 days .

Though not tropical now, its movement may increase rainfall and raise attention if organization begins.

Sea Surface Temperatures: A Warm Platform

  • The Gulf of Mexico continues to show SSTs 2–4°F above average, providing a warm environment for storm development later this season.

  • Caribbean and Main Development Region (MDR) SSTs also remain elevated, keeping hurricane fuel accessible .

Atmospheric Setup: Suppression in Play

  • Wind shear remains moderately strong across much of the basin, hindering storm development.

  • Saharan dust is still prevailing over the eastern Atlantic, suppressing early-season storm growth.

  • Moisture levels are slowly increasing in the Gulf and Southeast U.S., signaling gradual support for convection.

Regional Weather: Rain on the Rise

  • Expect increased showers and thunderstorms along the Southeast U.S. and Gulf coasts as the trough approaches.

  • Florida will likely see scattered afternoon storms, typical for July, especially as the trough draws moisture inland.

Prep Tip of the Day: Be Rainwise

Even without strong winds, heavy rainfall can pose serious hazards:

  • Track the trough’s movement—it could bring localized flash flooding to Gulf coast areas.

  • Ensure storm drains and sump pumps are clear and functional.

  • Keep sandbags and quick barriers ready if you're in low-lying zones.

  • Test your NOAA Weather Radio and mobile alerts to stay ahead of rainfall warnings.

Looking Ahead: Waters Stay Warm—Storms Could Spark

Although the tropics are peaceful now, the combination of warm ocean temperatures, easing atmospheric inhibitors, and growing seasonal moisture suggest readiness for evolution. The trough may serve as the first spark of Gulf activity, with a watchful eye needed through mid- to late-week.

Atlantic Hurricane Outlook – June 1, 2025: Opening Day, But All’s Quiet… For Now

June 1 marks the official start of the 2025 Atlantic hurricane season. No storms are currently active, but rising sea surface temperatures and favorable patterns suggest a potentially busy season ahead.

The Atlantic hurricane season officially begins today, June 1, and while the tropics are currently quiet, forecasters are already eyeing the environmental conditions that could lead to a very active season. For residents in hurricane-prone regions, now is the time to prepare—not relax.

Atlantic Basin: Calm Start to the Season

As of the latest update from the National Hurricane Center (NHC), there are no active tropical systems, no areas of concern, and no immediate threats expected over the next seven days.

This quiet opening is not unusual. Early June often sees little activity in the deep tropics. However, this calm is not expected to last. Sea surface temperatures are running well above average, and the atmospheric setup is trending toward conditions favorable for development later this month.

Sea Surface Temperatures: Running Hot

The Atlantic basin is notably warm for this early in the season, providing more than enough fuel for potential tropical cyclones.

  • Gulf of America (Mexico): 2 to 4°F above normal, with widespread areas exceeding 86°F (30°C)

  • Caribbean Sea: Similar temperature anomalies, especially in the western basin

  • Main Development Region: Continues trending above average

Historically, warmer-than-average waters correlate with more frequent and intense storms.

ENSO Neutral: La Nada Takes Over

The El Niño–Southern Oscillation (ENSO) is now in a neutral phase. With El Niño in the rearview and La Niña not yet in play, we enter what meteorologists call "La Nada"—a neutral state that often removes inhibiting influences on hurricane formation.

  • Decreased wind shear is expected across the Atlantic basin

  • A neutral ENSO often correlates with average to above-average storm development

  • Other patterns, like the Madden–Julian Oscillation (MJO), may become more influential later in the month

Saharan Air Layer: Dust Still in Play

The Saharan Air Layer (SAL) continues to stream across the Atlantic from Africa, bringing with it dry, dusty air that temporarily suppresses tropical development.

  • Inhibits cloud formation and convection

  • Increases atmospheric stability

  • Introduces vertical wind shear

The SAL typically begins to weaken later in June, removing one of the key atmospheric barriers to tropical development.

Eastern Pacific: Alvin Weakens

Tropical Storm Alvin, the Eastern Pacific's first named storm of the season, formed earlier this week and is now weakening.

  • Location: Approximately 710 miles south of Baja California

  • Movement: Northwest at 13 mph

  • Maximum Winds: 50 mph, weakening

  • Forecast: Expected to dissipate within 36 hours

Though Alvin poses no threat to land, its formation signals that tropical systems are beginning to stir in the broader region.

Florida Forecast: Statewide Conditions Typical for June

Across the state of Florida, today's weather reflects classic early summer patterns.

  • North Florida: Highs in the upper 80s, lows in the mid-60s, low humidity, mostly clear skies

  • Central Florida: Highs near 90°F, afternoon humidity and a slight chance of thunderstorms

  • South Florida: Highs in the mid-80s, lows in the upper 70s, muggy with isolated afternoon storms

These are the kinds of conditions that typically precede the onset of more frequent tropical activity in late June and July.

Preparation Tips: Start Now, Not Later

With the season now officially underway, take time today to prepare while skies are still clear.

  1. Review your family emergency plan and evacuation zone

  2. Check and restock your hurricane kit

  3. Confirm your insurance coverage and take property photos

  4. Sign up for local emergency alerts and follow trusted forecast sources

  5. Bookmark Cat5Prep.com and the National Hurricane Center

Looking Ahead

Although the season begins on a quiet note, forecasters warn that this calm is likely temporary. Record sea surface temperatures, a neutral ENSO, and easing wind shear all point to increased tropical activity as we move deeper into June.
