El Niño Pacific Surge +1.8°C Central Pacific

Lowell is Hawaii's third storm in just over three weeks. During strong El Niño cycles, weakened trade-wind vertical shear and anomalous +1.8°C ocean warmth southwest of Baja California provide continuous high-octane fuel for tropical cyclones tracking across 140°W into the Central Pacific basin without weakening prematurely.
