As of that advisory, the storm’s center was pinpointed near latitude 29.4 degrees North and longitude 87.2 degrees West, with the position considered accurate within 30 nautical miles. Bertha was moving toward the northwest at approximately 5 knots, on a heading of 305 degrees.

By early Thursday morning, July 23, the storm is forecast to be near the coast with maximum winds around 40 knots. Later that same day, the system is expected to still be over water with winds down to 35 knots.
By Friday morning, July 24, the storm is projected to be inland with winds near 30 knots, and by Friday evening it is forecast to become a post-tropical system with winds around 25 knots as it pushes further inland.
The extended outlook calls for Bertha to fully dissipate by the evening of Saturday, July 25.
