Update
Sea fog and coastal fog across southeast georgia was lifting
northward as the warm front lifted north of the altamaha river.

Went ahead and cancelled the dense fog advisory for the marine
areas due to the fog shifting north. However, sea fog may briefly
redevelop Monday morning ahead of the cold front off the southeast
georgia coastal waters. Lowered overnight lows in most locations
due to the temperatures already being below forecast lows this
evening.

Temperatures should remain steady overnight as cloud cover
increases from the west. A weak cold front will approach the
region from the northwest overnight, bringing an increased chance
of showers across the western half of the region before daybreak
on Monday. Scattered showers are then expected along the frontal
boundary as it slowly slides southward through the region during
the day on Monday. Overall QPF amounts are expected to be less
than one quarter of an inch.

Aviation
Ceilings are forecast to lower late in the night and towards
daybreak on Monday as a cold front approaches the region. A chance
of showers is expected at all the TAF sites as the front moves
through the region. Winds will shift to the northwest to around 10
knots behind the front, and stratus in the 2.5-4kft range will
continue through the end of the TAF period.

Marine
Cancelled dense fog advisory over the marine waters due to fog
lifting northward. Fog is possible near daybreak and into the
morning hours on Monday ahead of the cold front. Winds will shift
to the northwest behind the front, and may briefly reach 20 knots
behind the boundary. SCA conditions are expected on Tuesday as a
coastal trough develops.

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.
