Wetter san diego1/13/2023 In January 2016, the research team also traveled to Tijuana, Baja California, Mexico to discuss El Niño consequences and preparation with the Tijuana Civil Protection Department. In anticipation of the 2015-16 El Niño, agencies initiated more communication and developed pre-plans for emergencies such as flooding to improve preparation and response times.Īgencies expressed a critical need for the most recent and up-to-date information and data to provide adequate lead-time for preparation actions. Local agencies noted minimal interagency communication and collaboration during previous El Niño events. Predicting El Niño storm events remains a challenge and this uncertainty complicates precautionary mitigation strategies and procedures. The 2015-16 El Niño-strengthened jet stream traversed primarily across northern California and the Pacific Northwest, rather than southern California, bringing significantly less rainfall than anticipated. This indicates a need for prioritizing the continuous maintenance of storm channels. Normally permitting can take up to two years, unless it is declared a state of emergency. Environmental permitting to clean storm channels and drains impeded prompt action for El Niño preparedness.To understand public perceptions of El Niño, we conducted a literature review of ~5,200 media articles (online news items, printed newspaper articles and transcripts of radio programs) published over the last four decades (1980 to 2016) and assigned them to categories that reflect prediction and forecasting, preparation and maintenance, economic impacts and damage, policy and community impacts. Ī section of Alvarado Creek, a tributary to the San Diego River, is an example of an urban channel with non-native vegetation and refuse that frequently floods during winter storms due to decreased channel capacity. El Niño warnings are widely disseminated to the public through media outlets such as the television news, radio, city of San Diego websites, social media (e.g., Facebook, Twitter, and YouTube), and mobile alert messages for smartphones. We found that knowledge and climate predictions, primarily available from the San Diego National Weather Service (SDNWS) and the University of California, San Diego (UCSD) Scripps Institute of Oceanography (SIO), are used to prepare and pre-develop plans in the event of an emergency. Our research team met with agencies such as the San Diego County Office of Emergency Services, the City of San Diego Department of Transportation and Stormwater, the San Diego National Weather Service (SDNWS), the City of San Diego Lifeguard Department and attended local El Niño meetings. We conducted surveys and interviews with local agencies and collected data and information to understand levels of preparedness. The 2015-2016 El Niño was predicted to be the largest El Nino event on historical record with possibly a greater impact than the 98 events. This encourages the need to broaden forecasts of a specific event toward a holistic approach that includes all available information including historical accounts of El Niño-related socioeconomic and physical impacts. Ĭhristina Stewart (SDSU, BS '16) and Tracy Nishikawa (University ofĬolorado, Boulder) interview Alex Tardy (NOAA). Areas that are prone to weather extremes may benefit from ENRC practices, such as providing more effective management for hazardous threats and bridging mitigation efforts with sustainable development. We reviewed strengths, challenges, and opportunities in San Diego’s El Niño preparation during historical and contemporary El Niño events. We developed a research plan focusing on the city of San Diego to determine the degree to which lessons identified during previous El Niño events had become lessons learned, which is a characteristic of an El Niño ready city (ENRC). The recurring nature of El Niño provides an opportunity for national and local decision makers and communities to prepare for extreme events, develop and implement mitigation strategies, and plan local responses. The 2015-16 El Niño developed into one of the largest events on historical record, which raised concerns for potential storm-related impacts and coastal damage such as erosion, sinkholes, and flooding over roads built in the San Diego River floodplain. Previous El Niño events in 1982-98 resulted in heavy precipitation, record flooding and coastal erosion in San Diego. Sea surface temperatures along the equator warm, often bringing wetter winters to southern California with above normal precipitation and frequent storms from December through March.
