GMZ400-102130- 325 AM CST Fri Jan 10 2025 .SYNOPSIS... A strong offshore flow is forecast to develop today in wake of a coastal low departing the region later this morning...and Gale Warnings have been posted through mid-morning on account of occasional sustained winds and frequents gusts exceeding 35 knots. Elevated northerly winds will linger through tonight before building high pressure relaxes the gradient and winds and seas diminish. Onshore flow will develop by late Saturday as the center of the high pushes east of the region. However, winds are expected to again shift northerly by late Sunday as another coastal low develops and pulls a cold front across the coastal waters. This round of offshore flow will then persist through the end of the forecast period. $$ GMZ430-102130- Sabine Lake- 325 AM CST Fri Jan 10 2025 ...SMALL CRAFT ADVISORY IN EFFECT UNTIL 9 AM CST THIS MORNING... ...SMALL CRAFT EXERCISE CAUTION IN EFFECT FROM 9 AM CST THIS MORNING THROUGH THIS EVENING... .TODAY...Northwest winds 15 to 20 knots with gusts up to 25 knots.
