Introduction To Hurricane Season
The Pacific Ocean is experiencing an intense hurricane season, with tropical storms forming in rapid succession due to El Niño conditions that emerged in June. This phenomenon has caused waters to grow warmer than normal, leading to a chain of unusual weather patterns around the world. According to University of Miami hurricane expert Brian McNoldy, "It's ramping up to be perhaps the strongest El Niño on record."
Understanding El Niño And Its Effects
El Niño occurs when low-level surface winds blowing from east to west across the Pacific are weakened or sometimes reversed, causing a shift in the jet stream and driving record global heat, severe droughts, wildfires, and shrinking water supplies. This phenomenon does not follow a regular schedule, occurring every two to seven years on average, and its effects can be mild or severe. McNoldy predicted that the current El Niño will peak during the coming winter but linger into 2027, stating "It doesn't turn off right away."
Impact On Hurricane Activity
The increased number of Pacific storms is a result of El Niño, with both the eastern Pacific and the central Pacific seeing four more tropical storms than normal to date, according to Matthew Rosencrans, lead hurricane season forecaster with NOAA's National Weather Service. This has led to a turbocharged hurricane year in the Pacific, with three Pacific hurricanes reaching Category 5 strength, tying a record set in 2002.
Comparison To Previous Years
The most active season on record in the eastern Pacific was 1992, when there were 25 named storms, while the central Pacific saw 14 named storms in 2015. In 2015, there were nine major hurricanes, of Category 3 or higher, in the eastern Pacific, but no reported deaths. Due to El Niño, forecasters said the eastern Pacific storms formed farther west and tracked more westward, remaining over the open ocean throughout their cycle.
Real-World Implications
The effects of El Niño are not limited to the Pacific, as it also curtails hurricane activity in the Atlantic Ocean. Tropical weather activity in the Atlantic has been virtually silent this year. The current El Niño has already caused catastrophic flooding in Hawaii and drenched Mexico's Pacific coast, with the potential for more severe weather events in the coming months.
Future Outlook
As the hurricane season continues, forecasters predict that the eastern Pacific will see even more tropical storms, with the potential for severe weather events in the coming months. The current El Niño is expected to peak during the coming winter but linger into 2027, making it essential for communities in the Pacific to be prepared for the potential consequences.
