A FEW HOURS AGO...SOME DEEP CONVECTION REDEVELOPED NEAR AND TO THE

THROUGH AN UNFAVORABLE ATMOSPHERIC AND OCEANIC ENVIRONMENT...AND IS
NOT LIKELY TO SURVIVE AS A TROPICAL CYCLONE FOR MORE THAN ABOUT 24
HOURS.

OF A MID-LEVEL RIDGE SO A CONTINUED WESTWARD MOTION IS FORECAST FOR
THE NEXT DAY OR SO.  THEREAFTER...A SLIGHTLY SOUTH OF WEST TRACK IS
EXPECTED AS THE SHALLOW REMNANT LOW IS STEERED BY THE
LOWER-TROPOSPHERIC TRADE WINDS.
