Marine Weather and Tide Forecast for Kaplan, LA

DISCUSSION
(Tonight through next Sunday)
Issued at 1151 PM CDT Sun Jun 14 2026

A weak frontal boundary is across central Texas and northern LA this morning. A very soupy air mass is along and ahead of the boundary with PWAT values near daily record highs along the Texas coastal bend into much of LA.

The boundary will stall across the region through the next few days while deep moisture remains in place. Multiple rounds of rain can be anticipated through mid week. Thunderstorms that do develop will be capable of producing very high rain rates while moving slowly. A flood watch has been issued for rainfall totals of 2 to 5 inches in the watch area with isolated locations receiving between 6 and 10 inches. A few locations have already received around 6 inches over the past 18ish hours, but accumulations have been spotty. Rain will likely be more widespread today and Tuesday.

A very small lull in convection may occur during mid week, however additional heavy rain will be possible late week. A weak area of low pressure is over northeast Mexico and will travel northeast along the coast through Thursday. There is a slim chance that the system attempts to organize somewhat before reaching SE TX or SW LA IF it manages to move slightly offshore, but regardless of development, a slug of deep tropical moisture will move across the local area potentially interacting with the stalled and diffuse frontal boundary. Rainfall totals will be highly dependent on the evolution and path of this system. Strong onshore winds are expected as the system passes and this may drive tides around 2 feet above normal.

This weekend another front may drift into the region keeping the weather somewhat unsettled. No chance of real cooling though, that is still months away.
