Stronger hurricanes could 'supercharge' extreme El Niño weather events in California
The National Oceanic and Atmospheric Administration (NOAA) predicts 15 to 22 named storms in the eastern Pacific this year, with 5 to 9 becoming major hurricanes, potentially intensifying El Niño-driven extreme weather in California. While few storms may make landfall, distant hurricanes could still bring heavy rain, large ocean waves, and lightning surges to the state, according to meteorologists.
The National Oceanic and Atmospheric Administration (NOAA) has forecasted an active hurricane season in the eastern Pacific, with 15 to 22 named storms expected this year, including 9 to 14 hurricanes and 5 to 9 major hurricanes (winds of 111 mph or stronger). This forecast coincides with a strong El Niño event, which NOAA Administrator Neil Jacobs confirmed has a 98% chance of occurring this summer, with an 80% likelihood of being moderate or strong. El Niño, a natural warming of central Pacific waters, typically suppresses Atlantic hurricane activity while increasing storm frequency and intensity in the eastern Pacific. This year’s strong El Niño could lead to an above-normal hurricane season in the Pacific, with a 70% chance of heightened storm activity, according to NOAA’s National Weather Service. Matthew Rosencrans, lead hurricane forecaster, noted that storm development may shift closer to Hawaii during El Niño years. While direct landfalls in California are unlikely, distant hurricanes could still deliver extreme weather, including heavy rainfall, large ocean waves, and lightning surges. Meteorologists warn that even storms hundreds of miles offshore could impact California’s weather patterns, potentially exacerbating El Niño-related conditions. The interaction between El Niño and Pacific hurricanes is well-documented, with strong El Niño years often correlating with fewer Atlantic storms but more intense Pacific activity. NOAA’s analysis shows that when El Niño is strong, the Atlantic sees only two-thirds of the average named storms and half the hurricanes, while the Pacific becomes more active. University at Albany atmospheric scientists Kristen Corbosiero and Brian Tang explained that El Niño’s wind shear disrupts Atlantic storm formation but has the opposite effect in the Pacific. California faces heightened risks this summer, as El Niño’s influence could amplify hurricane-driven weather disruptions. Experts emphasize preparedness, as even indirect storm impacts may lead to flooding, coastal erosion, or power surges. NOAA’s seasonal outlook underscores the need for vigilance in both Pacific storm tracking and El Niño monitoring.
