1003 AM PDT SUN SEP 27 2026
SYNOPSIS
TROPICAL DEPRESSION EIGHTEEN-E IS WELL NW OF THE
REGION AND WILL CONTINUE MOVING FURTHER AWAY FROM THE WATERS
EARLY THIS WEEK. THIS WILL CAUSE FRESH SE TO S WINDS OVER THE
WESTERN PORTIONS OF THE GUATEMALAN OFFSHORE WATERS TO DIMINISH.
WEST TO NORTHWEST SWELL WILL LINGER OVER THOSE WATERS THROUGH
THE NEXT FEW DAYS. OTHERWISE, MODERATE OR WEAKER WINDS EXPECTED
TO PREVAIL ACROSS THE OFFSHORE WATERS WELL INTO THE UPCOMING WEEK
ALONG WITH MOSTLY MODERATE SEAS.
