Marine Weather and Tides
Madisonville, LA

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

Sounding discussion
The upper air release this evening was routine with no problems
encountered. The 00z sounding indicated an unstable but drier
atmosphere when compared to the profiles from this morning and
yesterday. The atmosphere was drier in both the lower and mid
levels and the precipitable water value was down to 1.71 inches.

Moderate south-southeast winds prevailed throughout the lower
levels of the atmosphere, with lighter and mainly east-southeast
winds in the mid levels, and generally moderate westerly winds in
the upper levels. 11

Prev discussion issued 401 pm cdt Sun jun 17 2018
short term...

tropical outflow band moved north through the coastal waters, then
inland, penetrating all the way into central mississippi by early
afternoon. This flushed out the moisture a bit to limit convection
til now. Moisture recovery, followed by some more advancing
convective banding in the coastal waters to still provide a chance
for rain this evening. Quite a bit of uncertainty in timing these
features, but suffice to say, not the typical diurnal rainfall
pattern. High pressure steadily builds from the east to provide a
pop gradient from isolated coverage east to pretty decent coverage
west.

Long term...

a relaxed onshore flow pattern should persist Tuesday through next weekend
to provide more typical daily rainfall chances coverage and warmer than
normal temperatures as subsidence and modified continental influences
increase throughout the week. 24 rr
aviation...

expectVFR to some MVFR conditions through the TAF period. Showers
have not been as widespread this afternoon. Have kept convection out
of most TAF sites. Confidence is low in coverage of convection for
tomorrow and have not included it in TAF in long range. ExpectVFR
conditions for Monday. 13 mh
marine...

strong gradient winds continue over the outer waters which prompted
a gale warning to be issued this morning. The winds are still
elevated and the gale warning continues through the evening hours
into the morning hours. Will have to continue to watch for
cancellation or extension depending on forecast trends. The tropical
wave tracking across the western gulf of mexico and the high
pressure to the east is the culprit of the hazardous coastal
conditions. Outside of the gale warning and small craft advisory
continues for a large portion of the coastal waters. Winds and seas
should continue to back off heading into next week as high pressure
builds back in and the pressure gradient weakens. 13 mh

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.
