829 am edt Thu oct 19 2017

Update Continued NE flow pattern today... With winds decreasing
slightly across coastal SE ga later in the day. Radar has been
showing a few bands of moderate-heavy showers. Much of our model
guidance has not handled this well... Though a few hi-res solutions
hint at these bands gradually shifting a little southward during
the day. Will limit chance pops to coastal counties of st. Johns
and flagler... Slight chance pops further inland. Made slight
adjustments to high temp forecast today based on the latest
consensus guidance.

Will let coastal flood advisory expire after 11am high tide
cycle in SE ga... And will maintain all other warnings advisories
as we continue to see minor-moderate flood stage reached on the
st. Johns and continued moderate onshore flow along the coast of
ne fl.

Aviation Goes-16 clearly showing the lower conditions with rain
bands along coastal counties of NE fl and low CIGS gainesville to
ocala. Tafs reflect expectation ofVFR conditions... With areas of
lower conditions through mid morning. NE flow continues over taf
sites with occasional gusts to 20-25 kts late morning thru
afternoon.

Marine No signficant changes for next cwf issuance. High pressure
will be to the north of the region through Saturday, then to the
northeast later in the weekend. A strong cold front is expected to
cross the region from the west Monday night into Tuesday.

Rip currents: high risk through Friday due to moderate onshore
flow and rough surf.

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.
