Emergency Management (EM) officials prepared for these events by staging physical resources and deploying human resources, largely based on decision support from the National Weather Service (NWS) in Brownsville and Corpus Christi. The decision support included pre-event e-mail “blogs”, occasional webinars that were shared with more than a thousand users in nearly every emergency support function, and individual phone calls between office staff and first-line EM Coordinators. This presentation will describe specific actions taken by decision makers across South Texas and the Rio Grande Valley to increase community readiness prior to the floods. These actions included staging search-and-rescue assets and identifying shelter locations in South Texas prior to the May floods, and clearing drainage canals of debris and staging rescue watercraft in the Rio Grande Valley prior to the October floods. The actions, based on effective communication of hazards, impacts, and response helped to ensure the safety of impacted populations once flooding began.
