Marine Weather and Tide Forecast for Delcambre, LA

SHORT TERM
(Tonight through Sunday night)
Issued at 305 PM CDT Fri Apr 25 2025

Today's airmass and convective activity is more reminiscent of summertime than mid-spring! Earlier today, convection was bubbling up across the entire CWA, but it is blatant to see high pressure ridging is building in as everything has dissipated. A few isolated thunderstorms will be possible through early evening, but not expecting anything major or severe.

The remainder of the short term period will be very warm and humid underneath high pressure aloft. Many area observations overshot the forecasted high temps today, so Saturday and Sunday's high temps were bumped up from the baseline NBM. This is resulting in forecast highs in the mid to upper 80s each day.

For those with outdoor plans, do not expect much in the way of cloud cover or precipitation helping to break the heat. Hydrate, stick to the shade and keep a close eye on those vulnerable to these conditions!

LONG TERM
(Monday through next Thursday)
Issued at 305 PM CDT Fri Apr 25 2025

High pressure remains well in control of the forecast into the start of next work week. A few weak shortwave pulses attempt to move down into the southeast US but they're all shunted off to the north of the high pressure dome. The ridge weakens a bit towards the midweek as a stronger shortwave makes its way across central Texas on Wednesday. This could be the first day to see any active convection in the longterm period.

Even with the potential of rainfall, it does not appear a break in the hot, humid conditions will take place through the end of next week. Expect highs in the mid to upper 80s each day.

AVIATION
(00Z TAFS)
Issued at 559 PM CDT Fri Apr 25 2025

A boundary is causing showers and thunderstorms to form in an east to west line across central Louisiana, impacting AEX. Impacts from convection should remain north of I-10.

After sunset convection will fade away leading to VFR conditions through most of the night. Near sunrise patchy fog is expected to form. Impacts will be felt more along the coast with VIS dropping into MVFR conditions and periods of IFR possible. CIGs are not expected to drop below VFR.

After sunrise (14Z), VFR conditions will return. Winds will be light through the period and mainly from the south.

MARINE
Issued at 305 PM CDT Fri Apr 25 2025

High pressure is building in from the southwest today and will remain in control through much of the period. Expect mostly dry conditions, mild to occasionally moderate onshore flow and 2 to 4 foot seas through at least the middle part of next week.
