Discussion
Update
Northeast swells with strong rip currents expected into mid
week at east central florida beaches...

currently-tonight... 15z CAPE sounding came in drier with a pwat back
down to ~1.6 inches as some deeper mid level moisture moved offshore
into early afternoon. Did see some morning convection across
southern martin county but it has since pushed offshore. It still
appears southern sections will have a low shower chance into this
evening with lake breeze and sea breeze boundary interactions before
activity dissipates into late evening. Short range models continue
to show mid upper level low just off the fl west coast with
divergence aloft across far SRN sections through the night. Will
linger some low shower chance across the far south in association
with this feature and deeper moisture lurking just south of the area.

Wednesday... Nnw low level flow in the surface to 925 mb layer will
advect a drier airmass over much of east central fl on wed. Pwats
are forecast to drop to 1.3 inches across NRN areas but linger
around 1.7 inches across martin county. Most areas will be dry with
warm temps but will continue a low shower chance across far srn
sections. Highs will be around 90 at the coast to the mid 90s across
portions of the NRN interior. Sanford will approach their record
high of 94 degrees. Long period northeast swells at the beaches will
continue the rip current hazard with strong rip currents possible.

Thu-fri... Dry air behind hurricane maria will dominate east central
fl, giving way to the low precip chances Thursday and early Friday.

Some moisture in south fl may advance north into the treasure coast,
with only a slight chance of thunderstorms. Friday, a low approaches
the eastern coast, increasing pops south (50%) to north (30%). Above
average high temps in the low 90s continue, with lows in the low to
mid 70s.

Previous extended discussion... Saturday-Monday... A cold front will
push through the southeast late this week, weakening as it
approaches north florida by Saturday. Guidance indicates a surface
trough or closed low developing offshore, though there exists
considerable model spread as to both the strength and placement of
the feature. Regardless, a period of building onshore flow is
advertised this weekend with steadily increasing moisture and pops.

Have capped precipitation chances at 50%, though this may need to be
adjusted upward should the trough low move over the area. Increased
cloud cover and developing maritime flow will drop temperatures from
their mid-week highs with mid-80s (coast) & upper-80s (inland)
expected.

Marine
Tonight... Onshore flow this evening will become S SW around midnight
and then W NW overnight. Wind speeds should remain 10 knots or less
with northeast swells continuing to 5-7 ft near shore and up to 7-9
ft offshore. Will continue SCA for seas all marine areas into this
evening with some near shore zones dropping below the 7 ft threshold
overnight.

Wed... W NW flow in the morning will become onshore near the coast in
the afternoon. The advisory for seas will continue at least into the
morning hours for the offshore waters with northeast swells
lingering to 6-7 ft offshore.

Thu-fri... As maria continues to lift northward, conditions will
gradually improve through the week. Seas 4-6 ft Thursday becoming 3-
5 ft on Friday. Light westerly winds in the morning, shifting east
with the development of the afternoon sea breeze. Precip coverage
will be sparse until Friday, with highest coverage along the
treasure coast, decreasing northward.

Hydrology
A river flood warning remains in effect for the st johns river near
cocoa, above lake harney near geneva, near sanford, near deland and
at astor.

River levels remain high over the middle st johns river basin, with
all forecast points above flood stage. The river stage near cocoa,
and above lake harney near geneva will begin a gradual decline
through the end of this week. The river stage near sanford, near de
land, and at astor are forecast to remain steady with some very
gradual decline from the middle to through the end of this week.

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.
