a cluster of thunderstorms in the East Pacific with a center of sorts near 8N 107W.



From the eastpac 5pm TWD:

"AN UPPER TROUGH AXIS EXTENDS FROM THE COAST OF MEXICO NEAR 18N103W SW TO 5N115W WITH DIFFLUENCE EXTENDING E TO ABOUT 95W. A LARGE AREA OF DEEP CONVECTION IS LOCATED NEAR THE ITCZ BENEATH THIS DIFFLUENCE ZONE...BUT THE BULK OF THE FORCING APPEARS TO BE DUE TO STRONG LOW-LEVEL SPEED/DIRECTIONAL CONVERGENCE AXES. INCIDENTALLY...THE GFS DEVELOPS AN AREA OF LOW PRES FROM THIS CONVECTIVE MASS WITHIN THE NEXT 48-72 HRS...BUT THE GFS ENSEMBLE ONLY SHOWS A WELL-DEFINED TROUGH FOR NOW. "
