• Storm surge is defined as an abnormal rise of water caused by a storm, exceeding the predicted astronomical tide.
• This phenomenon can lead to significant coastal flooding, especially when combined with the normal tide to form a 'storm tide.' The severity of storm surge depends on various factors, including the storm's size, intensity, angle of approach, coastline shape, bathymetry, and tide timing.

Impact & Risks

Storm surge poses a significant threat to coastal communities, with the potential to cause widespread flooding and property damage. It is important to note that the hurricane category does not directly measure surge risk, and areas outside the forecast cone can still experience life-threatening conditions. The combination of rising water levels and strong waves can make evacuation routes impassable and endanger lives. Residents in low-lying and coastal areas are particularly vulnerable to these impacts (Storm Incoming, 2026).
