ON JULY 20, 2009.

A tropical disturbance (also known as a tropical wave) has moved over Barbados and is continuing on its general path toward a direction just a little north of west.  The image above is a color-enhanced infrared.  At the time of this posting, the National Hurricane Center is indicating that they do not expect development into a cyclonic system within the next 48 hours.  To be cyclonic there must be a closed rotation.  tropical depressions, tropical storms, and hurricanes rotate counterclockwise in the northern hemisphere (except in the higher levels of the storms).  For more information on cyclonic circulation in a hurricane go to this link:

My most trusted source, Dr. Jeff Masters, at this time expects the disturbance to be torn apart by upper level wind shear within the next few days.

To follow Dr. Masters’ reports, go to the following link:
