Tim's Weather World: The Fujiwhara fudge factor

Thumbnail image for 111early.gifThe Atlantic hurricane season has sprung to life in the past few days.

One major hurricane, a tropical storm and another system that appears likely to become a named system, are all lined up in the Atlantic.

Hurricane Earl may have weakened to a Category 3 storm but it is still strong and could graze the Outer Banks of North Carolina as early as late Thursday.

Right on its heels is tropical storm Fiona. Fiona will probably steer a course a bit further east and out to sea.

One fly in the ointment, and there are many when it comes to forecasting tropical cyclones, is something called the “Fujiwhara Effect”. When two tropical systems are close enough to each other, they can sometimes spin or orbit around a common center. The larger storm dominates at the expense of the smaller storm one — so Earl could end up taking some strength from Fiona.
