Marine Weather and Tides
Arabi, 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.

area forecast discussion
national weather service new orleans la
335 pm cdt Mon jun 18 2018

Short term
Large tropical wave disturbance that was traversing the gulf is
currently moving ashore into texas and expanding outward into
louisiana where synoptic scale flow pattern is influencing the
moisture surge. Squall bands have been the main mode of rainfall
delivery into the forecast area today, with gusts 30-40 mph at
times and localized short rain bursts in the 3-4 inch hour ranges
for very short durations. We may see another round or two of these
bands approach the coastal areas this evening but general trend
should be for rain to taper from east to west overnight. Pops and
temperatures should be closer to typical Tuesday. Drier air noses
in from the east as subsidence settles into the region as an
extension of the bermuda ridge. This should limit convection
considerably for Wednesday.

Long term
Nearly steady-state flow pattern becoming established mid-week
with bermuda ridge extension staying in place for lower than
normal rain chances and higher than normal temperatures. A fairly
decent frontal zone stalls just north of the forecast area this
weekend but becomes diffuse quickly with little to no impact to
the forecast area.

Aviation
A broad area of light to moderate rain will continue to affect kbtr,
kmsy, khdc, and kmcb through 00z. Periods of MVFR ceilings and
visibilities could occur at times as bands of rain move through.

After 00z, rain should come to an end, and prevailingVFR conditions
are expected through tomorrow morning. Another round of scattered
convection could develop near kbtr and khum tomorrow on the eastern
side of a broad low pressure system over texas. Any impacts from
convection should be short-lived tomorrow. 32

Marine
A fairly tight pressure gradient remains in place over the open gulf
waters west of the mississippi river this afternoon. Onshore flow
of 15 to 20 knots and seas of 4 to 6 feet will persist over these
western waters through tomorrow morning. The pressure gradient will
gradually begin to ease tomorrow night and Wednesday as the low over
texas weakens and a broad ridge of high pressure strengthens over
the eastern gulf of mexico. Winds and seas should drop to around 10
knots or less, and seas should fall to 3 feet or less for the latter
part of the week and the upcoming weekend. 32

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.
