SHALLOW STRATOCUMULUS FIELD IS STILL SEEN IN SATELLITE IMAGERY
TONIGHT WITH NO ASSOCIATED DEEP CONVECTION. ANY CONVECTION IS
WELL N OF THE REGION. A RECENT SCATTEROMETER PASS INDICATES
WINDS OF 20 TO 30 KT JUST ALONG THE N BORDER MAINLY WEST OF THE
LOW CENTER. THE REMNANT LOW WILL CONTINUE TO DRIFT W-NW THEN W
OVER THE NEXT 48 HOURS HOVERING ALONG 31N BEFORE DISSIPATING
LATE TUE. ASSOCIATED WINDS AND SEAS WILL DIMINISH TO 20 KT OR
LESS AND 8 FT OR LESS BY SUN AFTERNOON.

A 1026 MB HIGH HAS REFORMED TO THE NW OF THE DISCUSSION AREA
EXTENDING A NARROW RIDGE E TO NEAR 38N135W AND THEN DRAPES TO
THE E OF THE REMNANTS OF MARIE AND A SECOND NARROW RIDGE FROM
NEAR 34N145W TO THE W OF THE REMNANTS OF MARIE. MEANWHILE
TROUGHING ALONG THE NW PORTION OF MEXICO IS GIVING A MODEST
PRESSURE GRADIENT BETWEEN THE EASTERN RIDGE AND TROUGH WHICH
WILL SUPPORT FRESH TO STRONG NW TO N WINDS AND RESULTANT SEAS 6
TO 8 FT JUST W OF THE BAJA CALIFORNIA PENINSULA. THE WINDS HAVE
DIMINISH AND THE SEAS WILL SUBSIDE THIS MORNING.

ELSEWHERE W OF 110W...THE RIDGING WILL GRADUALLY SHIFT WESTWARD
DURING THE NEXT 48 HOURS AS THE REMNANT LOW OF MARIE CONTINUES
TO THE W-NW THEN W. THE RIDGE WILL SUPPORT MAINLY GENTLE TO
MODERATE TRADE WINDS AND 4-7 FT SEAS WITH MIXED SW SWELL.

E OF 110W...CONDITIONS WILL REMAIN FAIRLY TRANQUIL WITH GENTLE
TO MODERATE WINDS AND 4-6 FT SEAS THROUGH THE NEXT 48 HOURS.
