Marine Weather and Tide Forecast for Dulac, LA

LONG TERM
(Monday through Thursday night)
Issued at 1231 PM CDT Fri Apr 25 2025

High pressure continues to dominate the area through the first part of the work week, leading to continued warmer than normal temperatures and low rain chances.

Wednesday will be a transition day of sorts as stubborn southern stream energy finally kicks out of the desert southwest toward the middle Mississippi Valley. As the upper trough moves eastward it will cause the upper ridge to flatten and shift eastward away from the local area. Sensible-weather-wise it still looks fairly quiet locally on Wednesday, though a couple stray showers and storms may develop during the afternoon, especially across northwestern areas.

As the upper trough continues eastward, a surface low will move into the middle Mississippi valley on Thursday, forcing a cold front southeastward into northern Texas and Arkansas. While this front is unlikely to ever reach the local area, an influx of moisture ahead of the front will lead to increasing rain chances on Thursday in the form of diurnally forced scattered showers and thunderstorms.

AVIATION
(18Z TAFS)
Issued at 1231 PM CDT Fri Apr 25 2025

Outside of convection expect generally VFR conditions to prevail through the period, though a few hours of IFR restrictions due to either low stratus or fog will be possible around daybreak and tempo groups have been included at several terminals. Biggest question is timing of any restrictions due to convection. For northwestern terminals (BTR, MCB, and HDC) showers and storms appear more likely given latest radar trends, and have included tempo groups for thunderstorms this afternoon. At other terminals, convection is less likely so prob30 groups have been included later in the afternoon/evening.

MARINE
Issued at 1231 PM CDT Fri Apr 25 2025

Expect benign conditions to prevail through at least the next 5 days as high pressure remains in control of the northern Gulf.
While there may be a few periods of winds in the 10-15 knot range, winds will generally be less than 10 knots with seas 1-3 ft.
