Heavy rainfall and high tides caused flooding across parts of the southern and western U.S., prompting emergency declarations, evacuations, and widespread news coverage. Videos of flooded communities circulated across social media, with many commenters expressing surprise at the severity of the flooding and concern for those affected. Some also questioned whether changing weather patterns and climate change may contribute to future flooding.
Online discussions raised concerns about people driving, walking, or hiking through floodwaters, as well as questions about water contamination and access to essential supplies. Some commenters criticized people entering floodwaters, while others shared personal experiences with flash flooding. Residents in affected communities also raised concerns about emergency response efforts and where to find reliable information and assistance related to climate and health.
Recommendation
With a potential super El Niño raising concerns about winter weather and flooding, communicators may use this period to prepare and update seasonal emergency preparedness messaging. Materials can emphasize the risks of entering floodwaters, including contamination, hidden debris, and rapidly changing conditions, as well as the importance of emergency supply kits and evacuation planning. Communicators may also prepare guidance on safe drinking water, cleanup precautions, and accessing assistance following a flood. Coordinating with local emergency management agencies can help ensure that resources are ready to share before severe weather occurs.
