EARL IS BECOMING MORE OF A PROBLEM FOR THE U.S.A. EAST COAST

I’ve watched television weather reporters today trying to explain what mechanism will hopefully turn Earl to the right – the sooner the better.  But not one of them mentioned the natural tendency for objects, fluids, and dynamic systems in motion to turn right (in the Northern Hemisphere).  I’m referring to the Coriolis Effect.  At times like this it is unfortunate that the Coriolis Effect cannot strengthened or weakened at will by those of us who would wish to keep these strong storms from plowing into us.

Here are two links for you if you are interested in the Coriolis Effect as it relates to weather:

I remember so well in late August, 1992, as I, my family, my students, and my friends and neighbors were hoping and praying for powerful hurricane Andrew to turn right and stay out over the Atlantic.  It eventually did turn right but not soon enough for us.  Our house was a total loss; the eye of Andrew went right over it.  We stayed in the community and had the house rebuilt; it was exactly one year before we occupied it again even though it wasn’t entirely finished.  I had purchased a 25′ travel trailer which was our palace-in-the-driveway for that year and we spent many Summers thereafter traveling all over the continent with our children.

Bottom line:  Lets hope for a drastic right turn on the part of Earl very soon.  The computer model tracks do not look promising for that.  Things are looking increasingly “ugly” for places like coastal North Carolina and points northward up the coast.  Though weakening is expected to occur before a possible visit to Nova Scotia – the prospect is nevertheless of considerable concern.

NOTE:  Some depictions of the successive forecast mean positions that you might see on television, your computer, or in the print media might be connected with an arcuate line right down the middle of the “cone of uncertainty.”  The National Hurricane Center still provides such a depiction but they favor this one because it has been shown that when people gaze at the midline they tend to either forget or ignore that the storm could fairly easily embark into other parts of the widening cone as it moves along.
