Synopsis for Baffin Bay to Rio Grande out 60 nm-
325 AM CST Sat Feb 22 2020

SYNOPSIS
Marine conditions will gradually improve through the
weekend as high pressure settles over the area. As this high pressure
shifts east, a light to moderate easterly to southeasterly flow
will return at the surface. A slight uptick in winds and seas will
occur Sunday into Sunday night as the pressure gradient strengthens
ahead of the next cold front due on Monday. This front is expected
to be weak, with little impact on the marine conditions. Hazardous
winds and seas are expected to return mid week due to a strong
surge of northerly winds.
