The ongoing heat wave poses risks of heat-related illnesses, particularly for vulnerable populations such as the elderly and outdoor workers. High temperatures can also strain energy grids and increase wildfire risks. Looking ahead, the strengthening El Niño could bring wetter-than-normal conditions to California, potentially improving water supplies but also increasing the risk of flooding, debris flows, and coastal erosion. Elevated sea levels along the West Coast, combined with high tides and strong surf, may exacerbate coastal flooding. However, the exact impacts will depend on storm patterns and whether precipitation falls as rain or snow.
