Update
Only isolated showers remain this evening for southeastern
georgia as northwest flow amplifies from a building upper level
ridge across the gulf. Calm to light westerly winds will allow
moisture off the gulf to form low clouds and fog late
tonight/early Wednesday. Locally dense fog is possible,
especially along and west of the i-75 corridor. Areas of smoke
from recent wildfires could also exacerbate visibility concerns
in areas east of i-75 as well. Rest of the forecast is on track.

Aviation
Vfr conditions are expected this period outside a period of
ifr/MVFR restrictions for fog and some low ceilings late
tonight/early Wednesday morning. Light and variable to mostly calm
winds overnight will allow for some localized dense fog and lifr
restrictions at the usual fog prone airfields. Winds will
increase mid-morning to around 5-10kts and mostly out of the west
to northwest. Seabreeze is expected to develop tomorrow
afternoon, with southeast winds moving a bit further inland than
today.

Marine
Southerly winds at 10-15 knots diminishing some tonight as
offshore flow develops. Long period swells of 3-5 ft nearshore
and 4-6 ft offshore will keep scec headlines offshore through most
of Wednesday. Onshore flow with local sea breezes will develop
again tomorrow afternoon. A strong high pressure center over
eastern canada will press southward by late Wednesday and
Thursday, pushing a weak frontal boundary to near the georgia
waters. This front will stall and then move back northward as a
warm front on Thursday night as a cold front enters the
southeastern states. This weather pattern will tighten our local
pressure gradient, with onshore winds gradually strengthening on
Thursday, reaching caution speeds for the near shore and offshore
waters by Thursday evening. Seas will build to small craft
advisory levels in the offshore waters on Friday as winds become
southerly. The front will cross our coastal waters late on Friday
afternoon, with offshore winds developing and remaining at caution
speeds on Friday night. Weak high pressure will then build over
our region this weekend, with winds and seas quickly diminishing
early on Saturday.

Rip currents: swells begin to fade tonight/early Wed as offshore
flow develops. Marginal moderate risk for rip currents will
continue for Wednesday.

It is not checked for accuracy either by anyone at L-36.com or by the source which is typically the US Government. See the NOAA web site for their disclaimer. 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.
