Rainfall potential increases across SE ga Sunday... Update Stratiform rainfall was fading across NE fl this evening on the wsw side of a weakening mesolow that was over duval county this hour, drifting eastward. Low pressure centers were forming wsw of apalachicola and offshore of the sc coast, with weak low level ridging strengthening over north florida from the south. Although deep moisture will continue over the area tonight, forcing mechanisms to generate rainfall will be weakening. The strength and depth of low-mid level SW flow out of the gomex across our suwannee river valley zones weakened per the 00z jax RAOB compared to 12z, and as the low level ridge axis builds northward through tonight, low level convergence along the gulf coast will transition to more ssw, and thus convection that does fire and drift inland will not make much inland progress through daybreak past our western tier counties, west of i-75. Mild overnight conditions will continue, with temps trending a tad cooler in the low mid 70s inland to mid upper 70s coast under mostly to partly cloudy skies. With soaked grounds across much of the area, potential for shallow ground fog increases tonight well inland where winds will be lighter and some cloud breaks may occur. Aviation MVFR ceilings will continue to impact ssi and gnv over the next few hours, with prevailingVFR conditions at other terminals this evening under fading -ra and ssw winds 10-13 kts along the coast to < 10 kts inland. Cloud cover is expected to thin and break apart further overnight, and with soaked grounds and light inland winds, may have intermittent periods of MVFR at vqq and gnv due to ground fog. Morning shower potential near ssi, with vcsh advertised for all terminal Sunday afternoon. |
Marine Surge in ssw winds over outer ga waters with sustained speeds 20-23 kts this evening supported a short 4-6 hr duration small craft advisory as low pressure developed along the surface front just north of our waters near the sc coast. Winds expected to gradually relax tonight to near 15 kts after midnight over the ga waters, to 10-15 kts over fl waters as surface ridge across south fl strengthens northward. Combined seas expected to fall from 3-5 ft to 2-4 ft Sunday. Rip currents: low risk. Hydrology Locations along the santa fe river including worthington springs are forecast to near minor flood early next week.

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. |
