WINDS TO GALE FORCE OFFSHORE OF COLOMBIA TONIGHT AND MON NIGHT. A
RECENT SCATTEROMETER PASS CAPTURED STRONG TO GALE-FORCE EASTERLY

IS OBSERVED SOUTH OF 08N AND EAST OF 30W.
..GULF OF AMERICA
HIGH PRESSURE SITUATED OVER THE EASTERN GULF PROMOTES MODERATE TO
FRESH RETURN SOUTHERLY WINDS AND SEAS OF 4-6 FT OVER WEST OF 90W.

THE NORTHERN BASIN LATE MON, BUT WILL LIKELY DISSIPATE AS IT MOVES
INTO THE CENTRAL AND EASTERN GULF THROUGH TUE NIGHT. HIGH
PRESSURE BUILDING OVER THE NORTHEASTERN GULF IN THE WAKE OF THE
FRONT WILL SUPPORT MODERATE TO FRESH SE WINDS AND BUILDING SEAS
ACROSS THE NORTHWEST GULF BY THU.
