Summary:
On August 29, 2021, Hurricane Ida made landfall at the coast of Southern Louisiana as a Category 4 Hurricane, bringing approximately 13ft of storm surge at certain locations. The event resulted in substantial flooding of several areas in Southern Louisiana, as well as electrical power disruption that affected more than 1M local citizens for almost a week. A unique aspect of this Hurricane event was the fact that as it moved further inland towards the Northeast US, it merged with another powerful non-tropical front causing it to regain tropical force winds and release record breaking rainfall across Pennsylvania, New York, and New Jersey.
Due to the extent of the flooding and power and gas-shortages, the GEER/NEER team decided to form two sub-teams: the Field team and the Virtual team (Table 1.1). Furthermore, the Field team followed a two-phase approach: a small group (Athanasopoulos-Zekkos, Jafari, Lin) visited the affected areas on September 10-14, 2021, to assess the level of impact of the event across a larger area, and then based on this early reconnaissance, a larger group (GEER, NEER, USACE, ASCE) visited targeted areas on October 9-18, 2021, to collect more information and field data and conduct a more detailed reconnaissance. The Virtual team provided much needed support to the Field team, by collecting information that was becoming available online on the event (social media, other agencies, etc) as well as background information on the affected areas. Finally, certain individual GEER team members (Hubler, Ahmed) also visited sites in Pennsylvania, New Jersey, and New York, to document the impact of the event in these regions.
