As of the 8 a.m. advisory Friday, issued by the National Hurricane Center, Tropical Storm Bertha was a weak tropical storm (tropical storms have sustained winds of at least 39 mph) with winds around 45 mph. The pressure wasn't relatively too deep at about 1008 millibars, so this storm is in its earlier/weaker stage.
The forecast is for the storm to continue as a tropical storm with a slight increase in sustained winds, to around 50 mph, as it moves to the west and northwest toward Puerto Rico and the Dominican Republic this weekend. By early next week it is forecast to move east of Florida and then turn more northeasterly toward Bermuda by the middle of next week. Friday morning's forecast did not include this storm becoming a hurricane.
Notice in the pictures above that the forecast track has a white line and blue area. The white line is the official forecast. The blue cone resembles the area the storm could go.
We'll continue to keep you updated regarding this tropical system.
