Bertha is now a category 3 hurricane. It should go west, then north and miss Florida.
Update (7-9-08): Bertha has dropped to a category 1.
Update (7-11-08): The official forecast track continues to show Bertha's center passing well east of Bermuda. However, the forecast remains uncertain
Those "weak and unpredictable" upper-level winds continue to wreak havoc on the NHC's ability to forecast Bertha's path. Sullivan succintly summarizes the divergence among the computer models as follows: "[Most] models still indicate a slow turn to the NNE. Some models make a sharper turn eastward. Some stall the storm right near Bermuda."
I saw the computer models (spaghetti strands) on the weather report today. They are wandering off in all directions.

Update (7-19-08): And now Bertha's a hurricane again.
