The Loop Current flows northward into the Gulf of Mexico through the Yucatán Channel and then exits eastward through the Straits of Florida. The current can be seen in this image from May 2010, which shows infrared observations from the Moderate Resolution Imaging Spectroradiometer on NASA’s Terra satellite, with warmer temperatures indicated by pink and yellow hues.

Over the past few years, hurricanes in the Gulf of Mexico have broken records for their intensity and the speed at which they have evolved from tropical storms into major cyclones. Hurricane Beryl, for example, strengthened quickly in early July 2024 to become the earliest category 5 hurricane on record. A few months later, in October, Hurricane Milton set a record for intensifying from a tropical depression to a category 5 hurricane in a little over 2 days.
A wealth of scientific research has implicated anomalously warm seas as the primary cause for intensifying storms in the region [e.g., Liu et al., 2025]. Ocean currents that circulate warm water, including the Loop Current, which transports water from the tropics to latitudes farther north, are also well-documented contributors to conditions around the Gulf today.
But how these currents have behaved in the past and how they are responding to climate change, which may have significant implications for coastal and inland communities adversely affected by cyclones, are not entirely clear. An interdisciplinary group of scientists from Mexico and the United States has been collaborating in recent years to find out.
