AMZ500 Synopsis For Flagler Beach To Jupiter Inlet Out To 60 Nm- 353 Am Edt Sat Aug 17 2019
Synopsis..The axis of the atlantic high pressure ridge will lift slowly northward from lake okeechobee this morning to near cape canaveral by Sunday night. As the ridge shifts north of central florida Monday night and Tuesday, an inverted trough will move northwest from the bahamas across east central florida and the adjacent atlantic. Winds wil remain out of the southwest and south through tonight, then become southeast from Sunday through the middle of next week. Scattered storms will push offshore later today, with threat for storms decreasing Sunday and Monday. Storm coverage will increase again beginning Monday night as the inverted trough approaches and moves across the local waters.
Gulf stream hazards..None. The approximate location of the west wall of the gulf stream based on the real time ocean forecast system as of Friday august 16th. 42 nautical miles east of ponce inlet. 31 nautical miles east of port canaveral. 24 nautical miles east of sebastian inlet. 15 nautical miles east of fort pierce inlet. 9 nautical miles east of saint lucie inlet.

7 Day Forecast for Marine Location Near Viera West, FL

Area Discussion for - Melbourne, FL
(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmlb 170820 afdmlb area forecast discussion national weather service melbourne fl 420 am edt Sat aug 17 2019 Discussion Current... Over the last 24h, the mid level trough over the eastern gomex and nofl has undergone n-s deformation in between the ridges to its east and west. There continues to be a sw-ne oriented swath of h25 divergence across this area which is supporting continued weak-moderate convection along the southern flank of the broad low to mid level trough. Ktbw radar shows coverage south of the nature coast is quite a bit lower compared to the past several nights, and ne steering flow has thus far kept the activity NW of lake county. Grids are still carrying a small pop NW of i-4 through sunrise. Today-tonight... Residual mid level troughing to the NW will continue to deform shear out as the western extension of the atlantic ridge noses westward into the peninsula. This allows the surface ridge axis to lift slowly northward, from around lake okee this morning into the southern half of the cwa, lying across the treasure coast counties by late tonight. While changes are subtle, slightly lower mean pwats advecting in from the SE coupled with slight backing of low level winds (especially se) should lead to slightly lower pops today, averaging about 50 percent (40 along the SE coast). Steering flow ranges from around 12kt near vrb-sua to 17kt lee-dab, so storms will move a little faster across the north today. Isolated diurnal convection expected to linger for an hour or two post-sunset before dissipating. MAX temps u80s-90f NW of i-4, and l90s to the se. Mins in the l-m70s. Sunday-Monday... Persistent troughing in the low levels of the atmosphere that has been in place for quite some time will begin to lift north and east up the eastern seaboard. As it does so the atlantic ridge axis will start lifting slightly to the north on Sunday as well. Diurnal scattered showers and storms expected to develop in the afternoon along both sea breezes, but west to southwesterly steering flow will transition the higher rain chances from the interior early in the afternoon toward the east coast later in the afternoon, especially north of melbourne. Models are showing a pretty big moisture gradient setting up with precipitable water around 2.00" N W of i-4 decreasing to around 1.7" toward the treasure coast. Pops follow this gradient with 50% across the northern sections and gradually tapering to 30% toward the south. Available moisture drops off slightly on Monday as the GFS is showing even more drier air moving in out ahead of a westward-moving inverted trough. Scattered diurnal convection still expected during the afternoon along the seabreezes with the eventual collision over the interior. With some drier air moving in, coverage of showers and storms shouldn't be as high as Sunday, especially for areas south of melbourne. Northern interior sections will see the higher chances with the better moisture and more boundary interactions. Also, forecast soundings are showing more dry air aloft to entrain with downdraft CAPE approaching 1000 j kg. So while coverage is not expected to be as high, storms that do form will have greater potential for strong wind gusts. Forecast for Monday has rain chances 20-30% along the coast and 40% interior. |
Max temps will be around 90 along the coast and low (possibly some mid) 90s inland. Lows in the low to mid 70s. Tuesday-Saturday... Shower and storm chances increase in the Tuesday Wednesday timeframe as the previously mentioned inverted trough approaches and moves through bringing deeper moisture across the area. At the same time, mid-level low troughing begins to re- establish itself across the NE gulf of mexico into northern florida providing some additional lift. Forecast GOES slightly above guidance with 60% areawide on both Tuesday and Wednesday. By late week into early next weekend, onshore flow patterns looks to become more established bringing the higher chances for diurnal showers and storms across the interior. Forecast has 40-50% chances across the interior and 30-40% along the coast. Max temps a couple degrees either side of 90. Lows in the mid 70s. Aviation Vfr through about 17z, followed by MVFR imc in scattered shra TS developing a mainly wcsb dominant regime. Given the expected storm coverage of 40-50 percent, and steering winds in the 15-20mph range, will probably taper back inherited tempo TS groups to a 2hr window (within the 17z-22z period) for all the local aerodromes. Marine Today-tonight... A gentle to moderate s-sw breeze today weakens and backs slightly tonight as the ridge axis begins to lift north into the local waters south of sebastian inlet. Seas 1-2ft near shore and 2-3ft offshore today subsiding to 2ft or less tonight. The risk for strong offshore-moving storms continues this afternoon and early this evening, especially north of sipf1, where SW steering winds will be a little stronger. Sunday-Wednesday... Slightly lower chances for showers and storms Sunday and Monday before increasing again on Tuesday and Wednesday. Seas will continue in the 1-2 ft range nearshore through Tuesday before building to 2-3 ft on Wednesday. Offshore waters will see generally 2 ft seas (maybe 3 ft well offshore) through Tuesday before building to 3 ft on Wednesday. Winds will be S SE on Sunday 10-15 kt, and from Monday-Wednesday winds will back to ese SE with winds around 10 kt.

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. |
