Pacific El Niño Meets Atlantic Niña in Rare Weather Shield
Summary
A rare weather situation is happening with a cooling event in the Atlantic Ocean called Atlantic Niña, while a warming event called El Niño is growing in the Pacific Ocean. This combination could reduce the number and strength of hurricanes in the Atlantic this season by creating conditions that make it harder for storms to form.Key Facts
- Atlantic Niña is a cooling of sea surface temperatures in the eastern equatorial Atlantic Ocean.
- El Niño is a warming of sea surface temperatures in the central and eastern Pacific Ocean.
- Both events together create higher air pressure, sinking air, stronger winds, and less rain in key hurricane development areas.
- This can act as an "atmospheric shield," reducing chances for Atlantic hurricanes.
- Strong Atlantic Niña events in summer are unusual and happen rarely.
- NOAA predicts El Niño will continue to strengthen through early 2027.
- Despite these effects, dangerous hurricanes can still occur even in suppressed seasons.
- The last very damaging hurricane during an El Niño year was Hurricane Andrew in 1992.
