The National Hurricane Center has released updated wind speed probability graphics for Tropical Storm Bertha, giving forecasters and the public a clearer picture of where tropical-force winds may develop over the next five days.
The graphics, which track the probability of 34-knot wind speeds, were last updated on Thursday, July 23, 2026, at 8:40 AM GMT. These probability maps are a key tool used by meteorologists to assess the potential reach of a tropical storm beyond its direct path.
Residents along the Atlantic Coast are encouraged to stay tuned to their local forecasts and monitor updates from the National Hurricane Center as Tropical Storm Bertha continues to develop.
