10/9/2019 Updated the Marine Zones. 9/4/2019 Fixed the weather maps due to NOAA moving them. 7/25/2019 New feature in the Airports section gives a link to 5 minute updates for data reports. 6/2/2019. Many thanks to a user for reporting an error on one of the Edit pages. The switch to PHP 7.2 caused many pages that previously worked to quit working.

Light northwest winds away from the coast will prevail, becoming light and variable overnight. Winds will become east northeasterly 5-10 knots on Friday. High clouds will stream across the region through the period. Prev discussion [1021 am edt] Near term [through tonight] Cool high pressure builds to the NW of the area today and north of the area tonight producing mostly clear skies light winds and unseasonably cool temps. Highs will be in the mid upper 70s for most areas except around 80 far south. Lows will range from the upper 40s across inland SE ga to the upper 50s to near 60 far south and along the coast. Short term [Friday through Saturday] The cool and dry conditions will continue into Friday morning with an increase in mid and high clouds during the day. Rain chances increase from southwest to northeast Friday afternoon into Friday night as a developing low pressure across the SW gulf of mexico rapidly tracks NE towards the gulf coast. NHC gives this system a 70 percent chance of developing into a subtropical or tropical system in the next 48 hours. There are continued discrepancies between the GFS and ECMWF on the exact track although the trend will be for some type of a system to pass to the west and north of the area on Saturday before lifting NE out of the area Saturday night. Main concern will be for heavy rain of possibly 1 to 3 inches depending on the exact track. Temps will average slightly above normal with warm overnight lows due to cloud cover. Long term [Sunday through Thursday] Low pressure will continue to track to the NE away from the area on Sunday and Monday with weak area of high pressure building in behind it. Will probably have somewhat of a lull of precip at that time. A cold front will traverse the area on Tuesday bringing a chance of showers and possibly a few storms. High pressure builds in behind |

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. |
