The HMPC evaluated the above list of hazards using existing hazard data, past disaster declarations, local knowledge, and information from the 2023 State Plan and the 2019 Wake County Plan to determine the significance of these hazards to the planning area. Significance was measured in general terms and focused on key criteria such as frequency and resulting damage, which includes deaths and injuries, as well as property and economic damage. One significant resource in this effort was the National Oceanic and Atmospheric Administration ’ s (NOAA) National Centers for Environmental Information (NCEI), which has been tracking various types of severe weather since 1950. The NCEI Storm Events Database contains an archive by county of destructive storm or weather data and information which includes local, intense and damaging events. NCEI receives storm data from the National Weather Service (NWS). The NWS receives their information from a variety of sources, which include but are not limited to: county, state and federal emergency management officials, local law enforcement officials, SkyWarn spotters, NWS damage surveys, newspaper clipping services, the insurance industry and the general public, among others. The NCEI database contains 1,239 records of severe weather events that occurred in Wake County in the 25-
year period from 1998 through 2023. Table 4.2 summarizes these events. Table 4.2 – NCEI Severe Weather Reports for Wake County, 1998 – 2023
