Conventional Satellite Imagery And Dropsondes From The National
Science Foundation G-V Aircraft Indicate That Gaston Has
Degenerated Into A Remnant Low Pressure Area. The System Consists
Of A Weak Low-Level Circulation Without Organized Deep Convection.
Maximum Winds Are Estimated To Be 25 Kt...And These Winds Are Likely
Occurring Only In A Small Area Of Showers Well To The North Of The

The Remnant Low Is Situated To The South Of A Weakness In The
Subtropical Ridge...And Is Drifting Westward. The Large-Scale
Models Predict Some Building Of Ridge To The North Of The Cyclone
Over The Next Few Days. Therefore...The Official Forecast Track
Indicates A Continued General Westward Motion With A Gradual
Increase In Forward Speed.

Although Not Explicitly Indicated Here...There Is A Possibility That
Gaston Could Regenerate Into A Tropical Cyclone During The Forecast
Period. This Is The Scenario That Is Being Suggested By Some Of The
Global Models.
