Marine Weather and Tides
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 through Friday night ...
a stationary surface low continues to spin just west of macon at
this hour with very weak flow aloft. This is helping to produce
widespread showers and thunderstorms across central ga, especially
east- central ga through this afternoon. Depending on the low
track, this could mean continued heavy rain across this area
through the evening, slowly diminishing overnight. Some high res
models show the low slowly lifting north this evening which would
reduce the chance for widespread flooding across central ga. This
will then push the precipitation toward athens. However, based on
model spread, feel the surface low will be slow to progress which
will result in localized (possible widespread) flooding through
the overnight, with the area of concern being east-central ga
Expect precipitation coverage to diminish late tonight early
tomorrow morning. Stratus and fog may be an issue in the morning
across central eastern ga. Precipitation will blossom yet again
tomorrow mid-morning early afternoon with the coverage being
dependent upon the surface low placement. Current thinking is that
we will see better coverage across or just south of the metro and
athens. We will see widespread thunderstorms across the entire area
though. Again, the precipitation may take a bit to diminish
overnight, leading to more flood concerns across east ga.
Over the next 36 hours, we expect some locations across central and
east ga to receive between 2 to 4 inches of rain with locally higher
amounts, possibly reaching up to 8 inches. With such saturated
soils, gusty winds with these storms could easily down trees.
long term Saturday through Thursday ...
main concerns in the long term period are the track of invest al90
(aka soon to be tropical storm alberto) and its rainfall footprint
through the entire period.
Nhc continuing to indicate high probability of TC development of
invest al90 to a tropical storm in the next few days, which confirms
trend of model guidance this week. 12z model guidance, including
gfs, ECMWF and ggem, continuing to slowly converge on track and
takes center to middle gulf coast somewhere between new orleans and
mobile. Even with well defined center, appears greatest impact,
particularly as it relates to north and central ga, will be very
heavy rain and flooding and not wind-related. That said, model
guidance seems to be conservative with amounts, taking the bulk
of it along and to the right of the track into southern al and ms.
Wpc QPF guidance seems to be on the right track, no pun intended
with broader swath of heavy rain that includes areas further east
including ga. Most concerning is models slowing center down after
landfall with GFS in particular lingering center nearby. Will
continue to monitor this closely.
For now have issued esf to account for heavy rain and hydrologic
threats. Very concerned that with pockets of very high antecedent
rainfall, will be vulnerable to a significant flash flood event.
see hydrologic outlook product issued this afternoon (esfffc).
Total rainfall of 4 to 6 inches with isolated amounts up to 7|
inches expected through Wednesday. Rainfall observed over the last
7 days have been 300 to 600 percent of normal over a fairly large
area, not just the pockets of very high rainfall see in the last
area of tsra moving out of south carolina and into eastern ga will
continue moving westward across the forecast area this evening.
Convection will dissipate toward 06z with isolated to scattered
showers for the rest of tonight. Convection will begin again
Friday with scattered to widespread shra tsra after 15-18z. Cigs
will become MVFR this evening and ifr after midnight. CIGS will
improve through the morning Friday. Winds will remain easterly
through the forecast.

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.
