AMZ400 Synopsis For Altamaha Sound Ga To Flagler Beach Fl Out To 60 Nm- 807 Pm Edt Thu Aug 22 2019
Synopsis.. Atlantic ridging extending its axis across the northeast florida waters tonight will slowly weaken and shift eastward as a tropical disturbance currently over the bahamas slowly organizes and moves northwestward towards the florida peninsula. This system will pivot northward and northeastward during the weekend, passing east of our local waters as it continues to gradually organize. Seas offshore may build slightly by Saturday night as this system makes its closest approach, but winds and seas will subside by early next week as this low pressure system accelerates northeastward away from the southeast u.s. Coast. Prevailing onshore winds this weekend will shift to southwesterly by Tuesday as a frontal boundary sinks southward towards the georgia waters.

The approximate location of the west wall of the gulf stream as of aug 22, 2019 at 1200 utc... 61 nautical miles east southeast of flagler beach. 72 nautical miles east of saint augustine beach. 84 nautical miles east of jacksonville beach. 92 nautical miles east of st simons island.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kjax 230055 afdjax area forecast discussion national weather service jacksonville fl 855 pm edt Thu aug 22 2019 Update No changes made to the forecast as much of the area has remained precipitation free this evening. Only a few isolated showers have formed along the sea-breeze as its pushed inland. With partly cloudy skies, GOES derived total precipitable water reveals a broad region of "dry" air from CAPE canaveral to brunswick, ga (pwats 1.6-1.8 inches). This verifies well with this evening's upper air balloon which observed a pwat of 1.76 inches. Under mostly clear skies tonight, temperatures drop into the low to mid 70s with coastal areas remaining warm in the upper 70s. Some patchy ground fog is possible tomorrow morning, but widespread issues are not expected. For tomorrow, expectations are very similar to today as the tropical wave axis slowly moves in from the southeast. Section of drier air observed via ua satellite is forecast to stay through tomorrow before slowly eroding on Saturday. Aviation Not many changes made to 12z TAF package. Light easterly winds continue into the evening with the east coast sea-breeze moving inland.VFR conditions prevail until early morning hours where |
some light ground fog is possible at area TAF sites. Marine Winds are around 10-15 knots this evening over area waters with waves 1-2 feet. Over the next few days, an area of disorganized showers and thunderstorms will move out of the bahamas and up the florida coast. Odds are slowly increasing that organization into a tropical system is possible. NHC recently increased 48 hour development probability to 30% and 5-day probability to 50%. Rip currents: low risk.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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. |
