TAMPA, Fla. (WFLA) — Tropical Storm Bertha, the second named storm of the 2026 Atlantic hurricane season, is expected to bring heavy winds and rainfall as it moves along the Gulf Coast this week.
To help track the storm’s westward movement this week, we have reactivated the real-time wobble tracker to monitor changes in movement relative to the expected path for the center of the storm.
HOW TO READ THE WOBBLE TRACKER
To read the wobble tracker, monitor the forecast loop’s progress with a focus on the eye of the storm. If the center of the eye strays off the National Hurricane Center’s track (red line), the storm is wobbling off the previously released forecast path. Multiple consecutive wobbles are later represented in the National Hurricane Center’s updated forecast cone upon the release of a new advisory.
While the movements may seem negligible at first glance, these wobbles do make a big difference when they compound into a change in the storm’s path.
This was the case when Max Defender 8 first launched the wobble tracker for Hurricane Ian, a Category 5 hurricane that was originally expected to make a direct hit on Tampa Bay but “wobbled” further south to its landfall in Charlotte County, Florida.
The wobble tracker watches the motion of hurricanes and tropical storms by using a combination of data from satellites, radar, the forecast trajectory, and the previous path the storm is on, to give an indication how the path is changing in real time.
The WFLA Wobble Tracker will remain actively streaming 24/7 until Bertha is no longer a system of concern.
