of Mexico. A cold front extends south-southwestward from the low
to the western tip of Cuba. Fresh to strong winds and seas of
7 to 9 ft over the eastern Gulf will gradually subside late
tonight and early Wed. High pressure crossing the northern Gulf
will lead to tranquil conditions Wed night through Thu, but by
