- Keeping an eye to the Central American gyre for late next week
The 2026 hurricane season's initial activity in the eastern Pacific includes Hurricane Amanda and two developing systems. A Central American Gyre (CAG) is expected to form by mid to late next week, potentially influencing tropical development in the Atlantic, western Caribbean, and southern Gulf. Models suggest increased storminess near Mexico's Yucatán and possible heavy rainfall for the Gulf Coast.
- Eastern Pacific hurricane season ramps up as the Atlantic stays dormant
The Eastern Pacific hurricane season is active with above-average activity predicted due to warm water temperatures, while the Atlantic hurricane season remains dormant. NOAA highlights contrasting conditions between the two regions, with the Eastern Pacific already forming storms like Amanda, Boris, and Cristina, whereas the Atlantic is quiet through its first week.
- Where could we see tropical development for the first half of June?
June is historically the least active month of the hurricane season, with only three Category 3+ hurricanes recorded in June since records began. Early June tropical development typically occurs near the U.S. in the western Caribbean, Gulf, and southeast Atlantic, driven by stalled fronts and the Central American Gyre. Current models show no immediate organized storm activity, but the Madden-Julian Oscillation may promote storminess by mid-June, though its influence is expected to be weaker due to a developing El Niño.
