Marine Weather and Tide Forecast for Cameron, LA

DISCUSSION
(Today through Thursday)
Issued at 1202 AM CDT Fri May 1 2026

Widespread rain and the possibility of flash flooding remain a majorconcern tonight and tomorrow as an upper-level trough will track across the Gulf coast Friday morning and into the afternoon.
A Flash Flood Watch extends across the northern portions of the CWA with expected rainfall amounts between 2 to 4 inches with locally higher amounts.

As the upper-level trough moves across the region conditions will be marginally favorable for severe weather but the SPC has kept us out of any risk area so far. Forecast soundings show long skinny CAPE profiles with 3-6 km lapse rates around 6 degrees. To put it differently, we will not be in an environment that will support robust updrafts. Instead, we will be looking at a long-duration rain event. Downshear Cordifi vectors indicate that storms will be fast-moving; if some of that momentum can reach the surface, we could have an isolated damaging wind threat.With the fast-moving nature of tomorrows event, the main flooding threat comes from training storms over one location. The timing for the highest flash flooding threat will be between 4 AM tonight to 4 AM early Saturday morning.

Behind the front, strong cold air advection will cause temperatures to drop nearly 20 degrees with highs on Saturday expected to be in the mid to upper 60s. A welcome sight for the region, especially with how warm conditions have been so far this year. Winds do not look consistent enough to warrant a high wind advisory but it also cant be ruled out for Saturday. Looking at the extended forecast, southern flow will resume on Monday with temperatures and dew points slowly climbing back into the mid-80s by the end of the week. The upper-air pattern will mainly be zonal for the rest of the week with rain chances near zero until Thursday when the next disturbance starts to move into the area.

AVIATION
(12Z TAFS)
Issued at 618 AM CDT Fri May 1 2026

Several rounds of showers with a few embedded thunderstorms will move west to east across the region today through tonight. While this convection will be mainly moderate rainfall, areas of heavier rain as well as any thunderstorms will be capable of reducing VIS, potentially for hours at a time if storms train over the terminals. In addition, winds will become gusty later this morning with frequent gusts expected through the evening hours. Ceilings largely maintain IFR with a few pockets of LIFR possible.
Conditions improve after midnight through 12Z tomorrow.

MARINE
Issued at 1200 AM CDT Fri May 1 2026

A slow-moving front will stall along the coast on Friday, causing heavy rain and the occasional thunderstorm. Gusty winds and low visibility should be expected with this system. On Saturday, the front will be pushed farther offshore, and north winds will rapidly increase. A Gale Warning will be needed for western coastal waters, and it could be extended farther east in later forecast packages. All other coastal waters, including lakes and bays, will be under a Small Craft Advisory. Waves will peak around 8 feet in the outer coastal waters. By Sunday, winds will decrease below advisory levels. Due to a high tide cycle, a Low Water Advisory doesnt seem necessary at this time, but please continue to watch the forecast for changes. By the start of next week, conditions will be benign, with winds below 15 knots from the south and waves around 4 feet.

FIRE WEATHER
Issued at 1200 AM CDT Fri May 1 2026

Multiple rounds of heavy rain will help alleviate drought conditions across the region, especially in central Louisiana and interior parts of southeast Texas. The rain will drop KBDI values across the region. After the rain on Saturday strong north winds will cause dew points to drop with minimum RH values down to 30%.
Thankfully with the recent rains, elevated fire weather is not a concern. For the rest of the forecast, winds will be from the south and weak while RH values will steadily climb.
