Post-Tropical Cyclone Gaston Summary

Gaston has been devoid of deep convection for more than 12 hours, and is now a swirl of stratocumulus clouds. Since the cyclone is moving over 22-23 deg C waters and embedded in northwesterly shear of about 35 kt, the likelihood that any new convection would reform is slim. Given this, Gaston is being declared a post-tropical remnant low on this advisory. Without any new convection redeveloping the vortex is expected to spin down rather quickly, and global models show Gaston opening up into a trough in about 18 hours.

The initial motion estimate is 065/15. The post-tropical cyclone should accelerate east-northeastward at the base of the mid- latitude westerlies today, and then turn northeastward ahead of a trough digging over Atlantic Canada prior to dissipation on Sunday.

This is the last advisory issued on Gaston by the National Hurricane Center. Additional information on this system can be found in High Seas Forecasts issued by Meteo France under WMO header FQNT50 LFPW and available on the web at http://www.meteofrance.com/previsions-meteo-marine/bulletin.
