SPAS has been the industry standard used to quantify rainfall accumulation in time, space, and magnitude for more than 20 years. SPAS outputs have been applied in hundreds of PMP and hydrologic modeling studies worldwide and are the foundation of our meteorological inputs for the most critical infrastructure such as dams, mining operations, and nuclear facilities. Over this time frame, we have completed nearly 1000 unique analyses of the most important storms globally. Several recent extreme rainfall events have been analyzed, including the record rainfall over Ft Lauderdale in April 2023, Nova Scotia in July 2023, and a destructive event in Indonesia during February 2023. One of the most unique events recently analyzed was the Rockport, WV July 18-19, 1889 storm, which produced over 20″ of rainfall in 2 hours in West Virginia. This storm caused extensive devastation and loss of life, but until now, had never been fully analyzed and applied to PMP development and engineering design. This is an example of the unique expert analyses that are only available from AWA and this continues the traditional of excellence in storm analysis that we have achieved for more than 20 years.
