DEEP CONVECTION ASSOCIATED WITH HECTOR DIMINISHED AROUND 2100
UTC...REDUCING THE CYCLONE TO NOTHING MORE THAN A SWIRL OF
LOW CLOUDS. HOWEVER...CONVECTION HAS NOT YET BEEN ABSENT LONG
ENOUGH FOR THE SYSTEM TO BE DECLARED A REMNANT LOW. HECTOR IS
EXPECTED TO DEGENERATE INTO A REMNANT LOW SOON AS IT CONTINUES TO
ENCOUNTER PERSISTENTLY STRONG EASTERLY SHEAR...LOWER SEA SURFACE
TEMPERATURES...AND A DRY AND STABLE MARINE-LAYER AIR MASS
ASSOCIATED WITH A NEARBY STRATOCUMULUS FIELD. DISSIPATION IS
FORECAST IN ABOUT 2-3 DAYS.

THE INITIAL MOTION ESTIMATE IS 340/04 KT.  HECTOR SHOULD BE STEERED
ON A SLOW NORTH-NORTHWESTWARD COURSE FOR THE NEXT DAY OR SO...IN
BETWEEN A LOW- TO MID-LEVEL RIDGE OVER MEXICO AND MID-TROPOSPHERIC
CYCLONE TO THE SOUTHWEST.  AS THE SYSTEM BECOMES WEAKER/SHALLOWER IN
NATURE...IT SHOULD TURN NORTHWARD AND MEANDER AS IT ENCOUNTERS A
BROAD CYCLONIC LOW-LEVEL FLOW WEST OF THE BAJA CALIFORNIA
PENINSULA.
