the trough axis, with seas building to 6 ft.

A front across the far se gulf waters is currently drifting wnw
as a weakening warm front, and should lose identity later this

through Tue night with fresh southerly return flow, and 3 to 5
ft seas, expected over the w gulf through Sun night, except for
an embedded swatch of strong se winds expected along the Tx
coastal bend tonight. Moderate se return flow forecast over the
