Marine Weather and Tides
6/25/2017 - NOAA is having a major issue that impact the 7 day forecast load times. Many users are reporting problems. The issue has been reported.
5/23/2017 - Worked with NOAA again to speed up the 7 day forecast load times. Thanks to them for being responsive.
5/19/2016 - There were issues with the 3 day airport observation history. I switched to another data source. Let me know if you see any issues with the data feeds.

23 06z issuance... Isolated showers and thunderstorms over
interior portions of southeast ms and southwest al have dissipated
as expected. Will likely see some redevelopment of isolated
showers and storms near the coast and just offshore late tonight,
primarily after around 23 109z Sunday (as indicated by hrrr).
During the day on Sunday, scattered showers and storms are expected
to develop spread inland during the course of the day. Localized
MVFR or briefly lower ceiling visibility conditions, along with
gusty winds, can be expected in and near any of the stronger
storms that develop on Sunday. Otherwise,VFR conditions expected
through most of the period for most locations. Light and variable
surface winds tonight, expect light south near the coast. A
predominately light southerly surface wind up to around 10 knots
Sunday afternoon. Showers and storms become more isolated once
again Sunday evening, with surface wind again becoming light and
variable. 12 ds

near term now through Sunday ... An upper level low continues to
drift westward across southern la and the adjacent northern gulf of
mexico on the southern fringe of an upper level ridge of high
pressure stretching eastward from the plains to the tennessee
valley. The combination of plentiful moisture (precipitable water
values between 1.7" and 2.0") and typical summertime instability
(mlcape values ranging between 1500-2500 j kg) has resulted in
development of scattered showers and thunderstorms mostly along the
advancing seabreeze this afternoon. A few storms have occasionally
pulsed up strong and have been capable of producing localized wind
gusts over 40 mph, frequent lightning strikes and very heavy
downpours. There will still be opportunity for additional isolated
to scattered storms to develop farther inland through the remainder
of the afternoon. Otherwise, typically hot and humid conditions
prevail outside of convection, with temperatures in the lower 90s
and dewpoints in the lower to mid 70s producing heat indices between
Convection should gradually diminish in coverage over inland areas
this evening with loss of daytime heating, though isolated storms
may persist through 9-10 pm. A lull in activity could then occur for
a few hours before additional isolated to scattered showers and
storms develop near the coast again sometime after midnight. Will
maintain 20-30% pops over southern areas, with the highest coverage
drawn near the immediate coast and beaches after 06z. Overnight lows
will range in the lower to mid 70s inland and 75-80 near the
immediate coast and beaches.
Our forecast area will remain between the upper low inverted trough
extending from the western gulf of mexico to southern la and another
upper trough digging toward the eastern CONUS Sunday. Plentiful
moisture and instability over our area will support another round of
scattered showers and storms developing from south to north through
the day along the seabreeze. Will have pops remaining in the high|
end scattered coverage range (40-50%) over most of the area. A few
storms may occasionally pulse strong with gusty winds, frequent
lightning and locally heavy rainfall given the moist and unstable
environment. Highs Sunday should range from the lower to mid 90s
inland, and around 90 near the immediate coast and beaches. MAX heat
indices generally range between 100-103, perhaps locally as high as
around 105. 21
short term Sunday night through Tuesday night ... Sunday night
through Monday, a combination of an upper ridge that has built
west over the gulf of mexico and an upper high over the nm tx
border keep an upper trough stationary and tilted over the lower
mississippi river valley to the southern appalachians. A surface
ridge that has developed over the central gulf of mexico keeps a
steady south to southwesterly flow over the lower miss river
valley and southeast, keeping deep layer moisture high (precip h20
levels around 2"). In combination with upper dynamics from the
upper trough and a daily gulf breeze expected to move inland, rain
chances around (near the coast) to a bit above (inland towards
the miss river valley closer to the better upper support) are
expected. With a bit of upper subsidence from the gulf ridge
counter balancing the better than seasonal rain chances, temps a
bit above seasonal expected at night (general low to mid 70s) ,
around seasonal during the day (upper 80s to low 90s).
Monday night through Tuesday night... A shortwave trough swinging
east over the northeastern CONUS flattens and pushes south the
gulf ridge, allowing the upper trough to the west of the forecast
area to tilt a bit more (gfs) or shift east a bit (ecmwf).
Consensus leans the current package towards the GFS in this time
frame. With the upper trough tilting, but remaining north of the
forecast area, a cooler wetter to warmer drier gradient sets up
over the southeast. For our little piece of the southeast, this
means a tighter diurnal temp range over the northern half of the
forecast area with better than seasonal rain chances, warmer and
a bit drier over the southern half (around seasonal temps and
long term Wednesday through Saturday ... In the extended, the
disparity amongst the guidance continues. The GFS is advertising
the upper trough moving off to the east quickly Wednesday into
Wednesday night, allowing the upper ridge centered over the nm tx
border to build east over the southern plains to the lower
mississippi river valley. The ECMWF is advertising the upper
trough continuing to shift east, to the east coast. Both are
advertising more shortwave energy diving into the upper trough
from over the plains, helping to maintain it. Both are advertising
a decrease in pops through the latter half of the week, the gfs
especially so. The GFS also is advertising a warmer scenario due
to the better eastward extent of the wester upper high. Have went
with a blend in the extended, with pops tapering downward to below
seasonal and temps moderating upward to a bit above seasonal,
with Thursday Friday being the driest and warmest. Saturday, will
see a return of better rain chances along with around to a bit
below seasonal temps as shortwave energy moves towards the
forecast area from the northwest.
Marine... The persistent pattern of showers and thunderstorms
forming over the marine area mainly during overnight and morning
hours before moving inland through the afternoon will continue into
early next week. A few storms will be capable of producing gusty
straight line winds and frequent lightning, and locally higher waves
and seas. Otherwise, expect a light to moderate southwesterly to
westerly wind flow to prevail over the marine area into next week as
a ridge of high pressure stretches westward over the central gulf of

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.
