LOW OF ANDRES IS LOCATED NEAR 20N122W AND IS DRIFTING TO THE E. 
FRESH TO STRONG WINDS ARE OCCURRING WITHIN 240 NM IN THE NW 
SEMICIRCLE OF THE LOW BETWEEN THE NW SIDE OF THE LOW AND THE 
RIDGING LOCATED TO THE NW. COMBINED SEAS ARE STILL 8 TO 12 FT. 
THE LOW WILL GRADUALLY SPINS DOWN THE ASSOCIATED WINDS AND SEAS 
AND SUBSIDE THROUGH 48 HOURS.

THE COMBINATION OF THE RIDGING AND LOW PRES TROUGHING OVER

CROSS EQUATORIAL SWELL OF 8 FT OR GREATER IS MIXING WITH SWELLS 
FROM ANDRES AND BLANCA ACROSS THE S CENTRAL AND SE WATERS. THESE 
COMBINED AND CONFUSED SEAS WILL SPREAD TO THE NE REACHING 10N BY
