Update
Widespread rain with embedded storms was moving across the
suwannee valley and interior southeast georgia this morning around
an area of low pressure across southern georgia. Rainfall rates of
1 to 2 inches per hour were occurring, and localized flooding is
possible as this area of rain slowly pivots to the northeast
through the day today. Slightly drier air was located across north
central florida this morning, with precipitable water values
around 1.8 inches, and lower rainfall chances are forecast across
interior northeast north central florida today. The main update
was to bump up the pops for the suwannee valley and interior
southeast georgia.

A weak east coast sea breeze is forecast to develop this
afternoon due to less cloud cover expected for the east coast.

Scattered showers and storms are forecast to develop along the
east coast sea breeze in the late afternoon to early evening. High
temperatures will be in the low to mid 80s for the suwannee
valley and interior southeast georgia due to the cloud cover and
rainfall, with upper 80s to lower 90s for the rest of the area.

Aviation
Widespread rain and embedded storms will continue across the
interior, mainly to the north and west of the TAF sites today. The
best chance for showers storms will be at kssi as the rain pivots
towards the area. A weak east coast sea breeze is forecast to
develop in the late afternoon, and scattered convection is
expected to develop near the northeast florida east coast taf
sites in the late afternoon through early evening hours. South to
southwest winds around 10 knots will prevail, become southeast
along the east coast as the sea breeze moves inland.

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.
