Southern Nevada Impacts Associated with Tropical Moisture from Hurricane Norbert (Invited Presentation)
Substantial runoff from this rainfall flowed through the Meadow Valley Wash, Weiser Wash, and the Muddy River, inundating and exceeding the capacity of the Interstate 15 drainage system. There was major damage to Interstate 15, which caused both north and south bound lanes to be completely washed away. The highway was closed for several days while transportation officials evaluated the damage and implemented repairs. Several earthen dams and levees were eroded and subsequently failed, resulting in evacuations and damage to infrastructure. This presentation will identify a few key components that contributed to such a high impact event. Societal and economic impacts across the Moapa Valley will be highlighted. National Weather Service Las Vegas tools, procedures, communication, and services will also be discussed.
