The purpose of this legislation, known as the Protecting Coasts and Cities from Severe Weather Act, is to enhance the understanding, observation, and forecasting of coastal flooding and storm surge events. It aims to improve safety and reduce property damage in areas that are particularly vulnerable to these weather-related threats. Key provisions of the legislation include the establishment of a program led by the Under Secretary of Commerce for Oceans and Atmosphere. This program will focus on developing accurate forecasts and warnings for coastal flooding and storm surges.
