dissipating along 96W during the late mornings. Otherwise, a
ridge will dominate the Gulf waters accompanied by gentle to
moderate anticyclonic flow, which is forecast to increase to a
fresh southerly breeze across the northwest Gulf waters on Sun

forecasted to shift south and extend across the central waters
