Marine Weather and Tide Forecast for Morgan City, LA

DISCUSSION
(Tonight through next Thursday)
Issued at 1147 PM CDT Thu Apr 9 2026

High clouds are streaming into the area this morning along a weak upper level disturbance and slug of moisture moving up the Texas gulf coast. This disturbance will initialize showers and thunderstorms near the coast from late this morning until around sunset this evening. The highest precipitation chances will occur over coastal portions of Southeast Texas with PoPs falling with increasing latitude. Rainfall totals of between a quarter and half inch are expected for areas that do see rain. While this is certainly not drought busting, every little bit helps.

An upper level ridge will build across the central and eastern gulf Saturday into Sunday aiding to stall a frontal boundary northwest of the region. The NBM suite has introduced isolated PoPs across southeast Texas Sunday due to the proximity of this boundary, but at present this isn't expected to be a significant rain maker anywhere across the region.

Much of next week will be a battle between the ridge over the central and eastern gulf and the stalled boundary and moisture plume over northeast Texas with the ridge expected to win out at least until late next week when a more progressive upper trof will help push the boundary into the area. While this isn't expected to provide materially cooler temperatures, it may offer the next real chance of precipitation along with the possibility of some severe storms as outlined in SPC's day 7 outlook.

A disturbance is set to move acreoss the area today, bringing a chance for showers and thunderstorms to most terminals. Activity is expected to concentrate across southeast Texas, closest to where this disturbance will be moving near.

Southwest Louisiana will also see a round of active storms in the afternoon, although storms will become more scattered the further east you go from southeast Texas. Best timing for vicinity storms was included at all remaining terminals.

Winds will vary around storms, but largely an east-southeast to southeast flow will prevail.

All conditions will improve with sundown.

A Small Craft Advisory remains in effect until 8 AM this morning. A weak upper level disturbance moving up the Texas coast will produce scattered showers and thunderstorms across the coastal waters and coastal lakes and bays from this morning through this evening with activity diminishing after sunset. Steady southerly winds between 10- 15 knots and no precipitation is expected through the middle of next week.

FIRE WEATHER
Issued at 1147 PM CDT Thu Apr 9 2026

Ongoing drought conditions across the region will continue to make smaller fuels available for burning, but steady southeasterly winds this weekend through next week will keep minimum RH values in the 40-60% range. A weak upper level low will produce scattered showers and thunderstorms across the region from late this morning through sunset this evening. Higher precipitation chances are expected closer to the coast with chances decreasing further inland. Significant precipitation is not expected this weekend or early next week.
