The National Hurricane Center has issued an updated Potential Storm Surge Flooding Map for Tropical Storm Bertha, with the latest revision posted on Wednesday, July 22, 2026 at 9:35 a.m. GMT.
The map provides a visual representation of areas that could experience storm surge flooding as Tropical Storm Bertha continues to develop. Forecasters urge residents in low-lying and coastal areas to stay informed and review the latest guidance from official hurricane tracking sources.
Storm surge is one of the most dangerous hazards associated with tropical systems, capable of pushing large volumes of water inland in a short period of time. Residents should have a plan in place and be ready to act quickly if warnings are issued for their area.
