The US Army Corps of Engineers (USACE) has updated hurricane inundation maps for coastal communities in Massachusetts as part of an update to the New England Hurricane Evacuation Study. These maps are created using a Sea, Lake and Overland Surges from Hurricanes (SLOSH) model developed by the National Weather Service (NWS) to estimate potential storm surge for Category 1-4 hurricanes. While these statistical models are based on historical and hypothetical hurricanes, each storm is different and thus may have different impacts than these computer models. To be safe, people are always encouraged to prepare for the impacts of one category higher hurricane than the storm’s official strength.
Individuals who live and/or work in coastal communities or communities with rivers or other waterways that connect to the ocean are encouraged to review their community’s Hurricane Inundation Map (below) and Hurricane Evacuation Zones to determine if their home or workplace may be vulnerable to flooding during a hurricane, and determine if these properties are in a hurricane evacuation zone. Those who live or work in inundation areas and evacuation zones should plan for and be prepared to evacuate during a hurricane and should listen to local public safety officials and weather forecasts before and during a hurricane for evacuation information.
