.SYNOPSIS...
A stationary frontal boundary remains stretched across northern

showers and storms over the eastern gulf waters overnight and into
Monday. This pattern is expected to remain for most of the upcoming
week. Winds will remain 15 knots or less and seas 2 feet or less for
most of the area, with the exception of the northern gulf waters on
Monday night, which may briefly reach cautionary levels around 15-20
knots.
