The chart above, acquired from the tropical page of Weather Underground at http://www.wunderground.com/tropical/ shows computer model “notions” of the future path of Investigation 91 which currently has the status of a tropical wave. The wave (or tropical disturbance) is currently showing no signs of cyclonic circulation. When, or if, if does it will become a tropical depression.
The red pathway is from the GFS image. This is the one I’m tending to value the most in this specific case since the GFDL does not take it far enough. In any case, it is believed that the leading half of an anticyclone moving from the west toward the east will prevent the system from continuing its rightward turning and will eventually cause it to move generally toward the west.
