Marine Weather and Tides
Abbeville, 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.

short term... Tonight and Thursday...

regional radar shows scattered showers and thunderstorms this
afternoon, mainly across southeast tx and central la. Much of this
activity should continue through the afternoon and into this
evening. Latest hires guidance continues to push a band of heavier
rain eastward into southeast texas late tonight, though there is
still some uncertainty as to when this will move into our area and
what rainfall totals we can expect. Eventually, these showers
should spread into southwest louisiana and across the area during
the day on Thursday.

After the last several days of heavy rain across southeast texas,
rfc flash flooding thresholds are still rather low at 2"-3" over
three hours and 3"-4" over six hours. While "official" forecast
totals through tonight are expected to be around or less than one
inch, 12z href guidance indicates the potential for more robust
convection to produce rainfall amounts that will approach flash
flood guidance. Additionally, guidance has preformed poorly over
the past several days with regards to the placement of convective
bands and rainfall amounts. The axis of steadier precipitation is
expected to shift northeast from central texas during the
overnight hours and any additional heavy rain received overnight
across southeast texas has the potential to produce local flash
flooding. Therefore, it was decided to lean on the side of caution
and extend the flash flood watch through Thursday morning for
southeast texas. Further east across western calcasieu and cameron
parishes, flash flood guidance is running higher and the
likelihood of precipitation exceeding said guidance is lower
resulting in the watch being cancelled.

long term... Friday through Tuesday...

the upper level low contributing to the heavy rainfall over the
past several days is expected to become integrated with a upper
level trough Thursday with the trough axis shifting east of the
region during the day Friday. The combination of the exiting
trough, the upper level high over the western atlantic expanding
into the eastern gulf, and height rises in advance of a digging
shortwave trough from the pacific northwest will result in weak
ridging across the ms valley through the weekend into early next
week. This will contribute to decreasing deep layer moisture with
forecast pwat values of less than 1.5" Friday through Sunday. This
will result in drier conditions and warmer conditions through
Sunday.

Early next week, the digging pacific shortwave and upper level
ridge will result in a more favorable pattern for return flow and
deep layer moisture will begin to rebound to climatological values
for late june. This will result in a return of the typical diurnal
convection beginning on Monday and continuing through the middle
of the week.

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.
