Wilmington weather office briefing, followed by map of the storm surge forecast for the area of the Brunswick nuclear power station, and Southport tides. [Update- short briefing from evening followed by longer morning briefing with maps.]






It’s unclear to us if the dot below Southport NC is Cape Fear or offshore.  It seems to be offshore.

Predicted Storm Surge Map Brunswick NPS

The map shows in the 1 to 6 foot range of storm surge in the area. Rainfall prediction map, below, is 6 to 10 inches. The rainfall prediction map above in the presentation, seems similar. However, even if the prediction were off and there was a storm surge of 7 ft and rainfall of one foot and a tide of 5 feet, it should still theoretically be ok, according to the information available – from the vantage of flooding the nuclear reactors. https://miningawareness.wordpress.com/2018/09/13/brunswick-nuclear-power-stations-cliff-edge-barriers-appear-to-fall-almost-8-feet-short-of-required-storm-surge-protection-level/

It is unclear if the tides are in addition to the storm surge. Above we assume that all must be added, simply to give a rough idea. Brunswick Nuclear Power Station is using the Sea Level Datum from 1929, which due to subsidence and sea level rise can be a problem. Subsidence has occurred during construction of at least one nuclear power station: https://en.wikipedia.org/wiki/Sea_Level_Datum_of_1929 https://en.wikipedia.org/wiki/North_American_Vertical_Datum_of_1988
