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
330 PM EST Mon Mar 8 2021

High pressure will build into the Southeastern United States from the north for early to middle part of this week. This will allow for a tight pressure gradient over South Florida along with dry mostly dry conditions, except a few fast moving light showers Atlantic waters. Breezy to windy north northeast winds will continue through middle of this week with even some gusts getting up to near gale force conditions especially over the Atlantic waters. Small Craft Advisory in effect for all of South Florida waters through at least Wednesday morning.

Gulf Stream Hazards: Seas will 6 to 8 feet tonight before decreasing slowly to 4 to 6 feet by end of the week.
The approximate location of the west wall of the Gulf Stream as of Mar 06, 2021 at 1200 UTC...

Short Term
Tonight through Tuesday... Satellite shows a band of cloud cover across the Atlantic coast and points east this afternoon. Although the deck of clouds is rather dense (holding down temps a bit today), KAMX is dry right now. Models show a weak surface/coastal trough axis developing overnight across the Gulf Stream. Some modest surface convergence within a rich easterly flow could spell some isolated showers across the waters, especially as timing of diurnal influences and even a modest H5 shortwave begin to interact later tonight. Outside of the Atlantic waters, can't rule out a stray shower over the eastern coast overnight and early Tuesday morning in this regime.

On Tuesday the trough moves downstream (southward to Cuba) leaving our region with a dry northerly upper level flow. With heigheights and thicknesses a bit lower expect another below average temperature day, especially across the Atlantic coast. With the pressure gradient remaining rather tight from the 1035mb high across the Carolinas, easterly breezes will again be expected. Relative humidity values will gradually be increasing as the easterly fetch continues to bring in more moisture, which will limit any fire weather concerns on Tuesday.

Long Term
Tuesday Night through Monday... A mid to upper level anticyclone will center over the Gulf of Mexico as meridionally elongated low-level ridging prevails from the South Atlantic States into the eastern Atlantic. Our position relative to the surface ridge should keep a robust pressure gradient in place with breezy ENE winds persisting into Friday. Hazardous marine and beach conditions will continue in this regime before winds start to relax by the weekend. Generally dry conditions are expected although brief Atlantic/East Coast showers can't be ruled out in this pattern. However with low predictability and minimum impacts see no compelling reason to stray from the blended model guidance which keeps precipitation chances largely below mentionable levels. Temperatures should remain near seasonal normals early in the period trending a bit above normal (especially Inland/Gulf Coast areas) by early next week.

Marine
Hazardous marine conditions can be expected across all of the south Florida coastal waters through tonight. Some gradual improvement is expected first over the Lake Okeechobee area then portions of the Gulf waters. That said, SCA (Small Craft Advisory) or at least cautionary headlines will be needed though midweek as pressure gradient remains rather tight from a strong high pressure moving eastward away from the Carolina coast.

.BEACHES... Strong northerly winds and elevated seas will continue today into Tuesday. This will continue the high rip current risk. In addition, building swells/seas will lead to 7ft surf heigheights within the surf zone. This may cause local inundation or possible minor beach erosion along the Palm beaches.
