Update Just a few diurnally enhanced showers popped across ne
fl and south of waycross in SE ga this afternoon as a low level moisture
axis drifted inland and fueled some precip along the east coast sea
breeze. Mostly dry conditions will prevail overnight less a light
coastal shower potentially impacting st. Johns and flagler county
where convergence and moisture will be deeper as hurricane maria
passes hundreds of mile east of the local coast tonight. Low level
winds will gradually back north overnight as maria begins to
track more to the nne of the region. Stronger subsidence and drier
air will filter over the area from the north with only passing
high cirrus clouds and some low level cumulus stratocumulus. Mild
low temperatures will fall into the upper 60s well inland to the
mid 70s along the coast and st.Johns river basin.

Aviation PrevailingVFR conditions overnight and into Monday at
all terminals except for MVFR CIGS this evening at sgj as moisture
with weak trough axis pivot southward down the fl atlantic coast.

Onshore flow will back slightly northerly overnight night, with a
return of breezy onshore flow along the coast Monday.

Marine Small craft advisory conditions continue over all legs
as combined seas continue to build. Recent 8 pm observations
included 6 ft combined seas with periods of 11 seconds at grays
reef buoy 41008 and seas up to 7 ft at the fernandina beach buoy
41112 with periods of near 13 seconds. Winds were nne 15-20 kts
with gusts up to 25 knots. Current SCA was on track with no
modification planned.

Rip currents: high risk through at least Monday. High surf was
reported along the coast today with breakers 5-7 ft with
occasional breakers up to 9 ft. The high surf advisory and high
risk of rip currents will continue through Monday for at least ne
fl beaches as swells continue to impact the local waters.

Hydrology Minor river flooding continues during each high tide
cycle from jacksonville southward to palatka within the st. Johns
river basin. Farther south down the river toward welaka and the ocklawaha
river basin high tide rises into minor and moderate flooding levels.

Strengthening onshore winds may keep the risk of minor to moderate
flooding in place during times of high tide through early this
week. A coastal flood advisory remains in effect for the st. Johns
river basin.

Moderate flooding continues along portions of the santa fe and st.

Mary's rivers, with minor flooding along the satilla river east of
waycross and portions of the upper suwannee river north of i-10.

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.
