AMZ600 Synopsis For Jupiter Inlet To Ocean Reef Fl Out To 60 Nm And For East Cape Sable To Bonita Beach Fl Out To 60 Nm- 936 Pm Edt Fri Aug 23 2019
Synopsis..A tropical disturbance approaching the region will bring generally southeast to southerly winds across the local waters for the next couple of days. Seas in the atlantic will be around 2-3 feet, occasionally higher. Seas in the gulf will be generally 2 feet or less. Increased moisture across the area will lead to increased periods of showers and Thunderstorms across all south florida waters. Gusty and erratic winds with locally higher seas are possible in and around any convection. The approximate location of the west wall of the gulf stream as of aug 22, 2019 at 1200 utc... 5 nautical miles east southeast of fowey rocks. 7 nautical miles east of port everglades. 4 nautical miles east of lake worth. 7 nautical miles northeast of jupiter inlet.

(on/off) Help NOTE: mouseover dotted underlined text for definition| Fxus62 kmfl 240100 afdmfl area forecast discussion national weather service miami fl 900 pm edt Fri aug 23 2019 Update The forecast remains on track this evening. Pwats from the 00z mfl sounding are 2.41 inches, indicating a favorable tropical environment for brief heavy rain showers tonight. Showers and thunderstorms over the gulf coast have died down, while scattered showers and storms continue over the east coast and adjacent atlantic waters. Expect this activity to persist on and off overnight, with some storms moving over the east coast metro. Prev discussion issued 736 pm edt Fri aug 23 2019 aviation... the winds should be light tonight over the TAF sites and then increase to 5 to 10 knots on Saturday from the south southeast over most of the TAF sites. The only exception is at kapf TAF site where it will be northwest on Saturday. Vcsh will continue for the east coast TAF sites tonight before vcts on Saturday at all of the east coast TAF sites. Kapf TAF site will remain dry tonight before vcsh for Saturday. Prev discussion... Issued 454 pm edt Fri aug 23 2019 discussion... tonight through this weekend... not a whole lot has changed from the previous forecast thinking. There's still a lot of uncertainty with the tropical disturbance, whose center is actually just off the southeast florida coast at the moment. While there are a few bands of showers and thunderstorms pushing southwestward across the gulf coast and waters, some subsidence on the immediate west side of the center of the disturbance has been suppressing shower and thunderstorm development across the east coast today. This system has become much better organized over the last 24 hours, with the national hurricane center now giving it a 70% chance of development over the next 48 hours and 90% chance over 5 days. Although eventual development is much more likely, there is still considerable uncertainty with the track of the system, which in turn will affect when the disturbance is finally able to develop into a tropical cyclone. Regardless of development, the potential for periods of heavy rainfall across south florida remains the primary threat for this system. Models are still pretty split regarding the track. GFS still separates the low-level and mid-level circulations, sending the low-level portion westward across the peninsula. The ECMWF brings the center briefly onshore the east coast before emerging back out over the atlantic as it pushes northward. Several other models lie somewhere in between. Pretty much all solutions carry at least some threat for heavy rainfall, but the location of this potential vary widely based on the different solutions. To account for this uncertainty, the weather prediction center has placed all of south florida in a marginal risk for excessive rainfall through tonight. Bands of showers and thunderstorms are expected to develop across the eastern portion of the disturbance over the atlantic overnight and into Saturday morning. If the center remains near the east coast, the heaviest rainfall could remain just offshore. However, if the center tracks further inland, the east coast could be set up for a couple rounds of heavy rainfall as the bands move onshore tonight. If this solution comes to fruition, some flooding of urban areas will be likely as the east coast metro areas have already received a surplus of rainfall over the last month. |
Where the system tracks over the next 12 to 24 hours will heavily influence the setup going into daytime Saturday and even into Sunday, both in regards to expected coverage of showers and thunderstorms and antecedent conditions from rainfall tonight and early Saturday. Deep tropical moisture will remain overhead throughout the weekend, so heavy rainfall will be possible with any showers and thunderstorms that are able to develop. However, again the coverage and location of the heaviest rainfall will greatly depend on what happens over the next 12 to 24 hours. If the wetter solution becomes more likely, an upgrade to a marginal risk for excessive rainfall would be likely and even a flood watch could be considered. Early next week... as the tropical disturbance lifts northward out of the vicinity of south florida, long range model guidance indicates that there should be sufficient moisture left in its path over the peninsula. For this reason, some of the stronger storms that form in the afternoon each day may bring locally heavy rainfall and isolated street flooding in poor drainage and low lying areas. Winds will become southerly to southwesterly throughout south florida which will help focus the majority of convection that develops over the interior lake okeechobee region as well as palm beach county. Mid-late next week... high pressure begins to build back into south florida, allowing for the return of a more typical summertime pattern. A frontal boundary is expected to stall out to the north of south florida which may act to enhance overall storm coverage. During this time, winds will become light and generally southerly, allowing for the formation of both atlantic and gulf sea breezes each afternoon. Convection should be driven by a combination of sea breeze and thunderstorm boundary interactions as well as daytime heating. Storm coverage is expected to be greatest over the lake okeechobee interior region as well as the gulf coast during this period. Marine... generally southeast to south winds are expected across the area through the weekend. A tropical disturbance currently centered off the southeast florida coast will bring periods of showers and thunderstorms to all waters tonight through the next couple of days. A more typical climatological pattern is expected starting out next week. Gusty and erratic winds with locally higher seas are possible in and around any convection.
