El Niño Phenomenon Triggers Weather Alerts in Peru and Hawaii

The El Niño phenomenon is driving anomalous weather patterns across the Pacific, leading to heightened climate alerts and tropical activity in both South America and the United States. In Peru, the warming of the central and eastern Pacific waters is causing an increase in sea surface temperatures, which can trigger torrential rains in typically arid coastal regions. Technical bodies including Senamhi and Indeci are monitoring the situation to prevent floods and mudslides, known as huaicos, while residents are advised to clear drainage systems and identify evacuation routes. Additionally, the DANA Bertha system is expected to bring increased wind and precipitation to the central and southern highlands of Peru, while Lima has experienced unusually high temperatures for August.

Simultaneously, El Niño is altering hurricane season trends in the Pacific, increasing the risk for Hawaii. The archipelago recently experienced two tropical systems in less than two weeks, a frequency described as exceptional for the region. Tropical Depression Moke brought heavy rains to the Big Island, where the ground was already saturated from the previous passage of Hurricane Lala. This saturation has increased the risk of flooding, with some areas receiving nearly three feet of rain in a single week. Other systems, such as Tropical Storm Iselle, have also been monitored in the Pacific, though Iselle is expected to move into open waters.
