   GMZ500-GMZ501-252300-  437 AM CST Sun Jan 25 2026      .SYNOPSIS FOR PASCAGOULA TO ATCHAFALAYA RIVER OUT 60 NM...    A backdoor front but will remain anchored over the coastal waters  for another 18-24 hours. By late this afternoon or early evening a  surface low will begin to slowly take shape in the northwestern Gulf  slowly drawing the front back to the north. As the surface low  deepens and moves northeast the pressure gradient will tighten and  onshore winds will increase to SCY criteria overnight and during the  day Sunday. Once the low moves to the north and then northeast of  the area Sunday afternoon a very strong cold front will quickly  surge through the area. Winds will quickly veer around to the  northwest Sunday evening and increase to sustained around 25-30 kts  with gusts approaching 40 kts. The tidal lakes will see the wind  increase first and could be flirting with Gales between 00 and 03z  Monday while the rest of the coastal waters will follow suit from  northwest to southeast. With that a Gale Watch has been issued for  all of the coastal waters from 00z Monday through 15z Monday. As  high pressure builds in Monday night into Tuesday, the northerly  winds will gradually decrease, but small craft advisory conditions  will persist.    $$
