Southeast Gulf of America .SYNOPSIS...Weak high pressure prevails across the NE Gulf, producing gentle to moderate SE winds over the western Gulf, and mainly light winds elsewhere.

In the meantime, a trough of low pressure near the southeastern U.S. coast is expected to move westward across Florida during the next day or so, and into the northeastern Gulf by Tue. Environmental conditions could support some gradual development of this system during the middle to late part of this week while it moves westward over the northeastern and north-central portions of the Gulf, accompanied by active weather. .OVERNIGHT...N winds 5 to 10 kt after midnight.
