First Atlantic hurricane activity spotted and here is what it means

First Atlantic hurricane disturbance of 2026 appears on the radar

The 2026 Atlantic hurricane season has recorded its first area of concern. On the morning of June 10, the National Hurricane Center identified a weak tropical feature in the Bay of Campeche, making it the first disturbance of the season to appear on official tracking maps. Forecasters were quick to note that conditions are not expected to be favorable for significant development and that the system poses no direct threat to the United States.

The disturbance can be traced to the remnants of Tropical Storm Cristina, which developed in the eastern Pacific and drifted slowly inland over Central America before its residual spin crossed into the southern Gulf and Bay of Campeche. A trough or weak low-pressure center is expected to emerge from the Yucatan Peninsula into the Bay of Campeche between Thursday, June 11 and Friday night, June 12, accompanied by thunderstorms, strong winds and rough seas across the west-central Gulf through Sunday, June 14.

While the system itself is not expected to develop significantly, the tropical air it carries could enhance heavy rainfall over northeastern Mexico and parts of South Texas later in the weekend and into early next week.

Quiet end of June expected across the Atlantic

Beyond this initial disturbance, forecasters are not anticipating much activity in the Atlantic for the remainder of June. Wind shear, surges of dry air and Saharan dust moving westward from Africa are expected to continue suppressing tropical development across much of the Atlantic basin through the last two weeks of the month. Climate Prediction Center maps align with those projections, showing little tropical activity expected in the Atlantic for the rest of June. However, odds for a tropical system developing in the Pacific during the last week of June are greater than 60%.

CSU lowers its 2026 hurricane season forecast

The quiet early-season outlook is consistent with a broader downward revision to the 2026 Atlantic hurricane season forecast. Colorado State University’s tropical meteorology team released its June update this week, lowering its projected storm count from 13 named storms, six hurricanes and two major hurricanes in its April forecast to 11 named storms, five hurricanes and two major hurricanes. Both figures fall below the long-term seasonal averages of 14 named storms, seven hurricanes and three major hurricanes.

The team also lowered its forecast for Accumulated Cyclone Energy, a metric used to measure overall hurricane season activity, from an index value of 90 in April to 70 in the June update. CSU projects that 2026 Atlantic basin hurricane activity will reach approximately 55% to 60% of long-term averages.

El Niño is the key factor

The primary reason for the revised forecast is the increasing likelihood of a moderate to strong El Niño developing by the peak of hurricane season, which runs from August through October. El Niño conditions in the Pacific produce higher wind shear and dry, sinking air over the Caribbean Sea and parts of the Atlantic, creating hostile conditions for hurricane formation and intensification. The stronger the El Niño, the more pronounced those suppressing effects tend to be.

There is also the possibility that this could become a super El Niño, meaning ocean temperatures along the equatorial Pacific warm to at least 2 degrees Celsius above average. Historical data shows that super El Niño Atlantic hurricane seasons have typically seen significantly fewer hurricanes and less overall activity.

Sea surface temperature signals are mixed. Parts of the eastern subtropical Atlantic are relatively warm, which can favor above-normal activity, but the eastern and central tropical Atlantic have cooler than average waters, which tend to suppress development.

Lower probability of US landfall

CSU also reduced its landfall probabilities for a Category 3 or stronger hurricane striking the United States coastline. The probability for the entire US coastline dropped to 24% from 32% in April, compared to a historical average of 43%. The probability for the US East Coast including Peninsula Florida fell to 11% from 15%, against a historical average of 21%. The Gulf Coast probability dropped to 14% from 20%, compared to a historical average of 27%. The probability of a major hurricane tracking through the Caribbean fell to 26% from 35%, well below the historical average of 47%.

A less active season is not a safe season

Despite the more favorable outlook, forecasters and emergency management experts consistently emphasize that a below-average forecast does not mean a no-impact season. It only takes one hurricane making landfall in a heavily populated area to define an entire season. Tropical storms and even tropical depressions can produce dangerous flash flooding without ever reaching hurricane strength. Anyone living in a hurricane-prone region is advised to prepare regardless of seasonal forecasts.
