25N MOVING WESTWARD 10 TO 15 KNOTS. THE POSITION WAS HELD NEAR
THE POSITION AT 27/0000 UTC IN ORDER TO AGREE WITH THE LONG-TERM
SATELLITE IMAGERY. CONVECTIVE PRECIPITATION...SCATTERED MODERATE

2 PM TWD.


TROPICAL WAVE EXTENDS FROM 13N48W TO 23N44W MOVING W AT 10-15
KT. THE WAVE REMAINS EMBEDDED WITHIN A MAXIMUM OF TOTAL
PRECIPITABLE WATER EXTENDING NORTHWARD FROM THE MONSOON TROUGH
REGION FROM 11N-22N BETWEEN 39W-50W AND COINCIDES WITH A 700 MB
TROUGH AXIS WITH A RELATIVE VORTICITY MAXIMUM CENTERED IN THE
VICINITY OF 20N46W ALONG THE WAVE AXIS. THE WAVE LACKS ANY
SIGNIFICANT DEEP CONVECTION AT THIS TIME DUE TO THE PRESENCE OF
THE SAHARAN AIR LAYER ACROSS MUCH OF THE CENTRAL ATLC.
