Update
Sctd showers and tstms continue to move south and west acrs lower
acadiana toward coastal southwest la and the adjacent coastal
waters. This activity developed in conjunction with a shortwave
crossing southeast la, and aided by strong aftn heating as high
temps reached the upper 90s late this aftn. Updated evening pops
to reflect ongoing convection which is expected to persist over
the next hour or two, a trend reflected in recent hrrr guidance.

However, activity will continue to weaken and diminish with the
loss of daytime heating, and convection should be mostly
dissipated by midnight.

mid upper high. Will be maintaining pops into the evening hours
over the eastern portion of the forecast area as this feature

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. Finally, tide and current data on this site is from 2007 and 2008 data bases, which may contain even older data. Changes in harbors due to building or dredging change tides and currents and for that reason many of the locations presented are no longer supported by newer data bases. For example, there is very little tidal current data in newer data bases so current data is likely wrong to some extent. This data is NOT FOR NAVIGATION. See the XTide disclaimer for details. In addition, tide and current are influenced by storms, river flow, and other factors beyond the ability of any predictive program.
