Strong northeast flow develops today along the coast and will
bring windy conditions along with a high risk of rip currents...

High surf and minor coastal flooding develop this evening and
will continue into Wednesday...

Near term today-tonight
Strong NE flow event develops today as high pressure remains north
of the region and low pressure develops along old frontal boundary
across SRN fl and tracks through the bahamas tonight. Forecast
remains on track for increasing NE winds late this morning along
the coast that continue through the afternoon and evening hours
and wind advisory has been posted for the atlc beaches of NE fl
and SE ga for sustained NE winds of 20-30 mph with peak gusts
into the 35-40 mph range at times. Still breezy inland with winds
of 10-20 mph with gusts of 25-30 mph possible. Isentropic lift
will help develop rainfall over coastal NE fl this morning and
continue this afternoon for areas mainly south and east of a line
from gnv-jax with some heavier coastal rain bands setting up
closer to the coast by this evening. Rainfall amounts will
generally be light in the 0.10-0.25" range but some isolated
higher amounts closer to 0.50" possible in areas south of sgj into
flagler county. MAX temps will struggle to rebound with all of
the cloud cover and only lower 60s expected along the coast with
mid to upper 60s inland. While a few heavier rain bands are
possible along the NE fl coast this evening, overall rainfall
chances along the NE fl coast will slowly decrease after midnight
as energy and lift aloft slowly pulls offshore and ends towards
morning.

Short term Wednesday through Thursday night Northeast winds
will start to decrease on Wednesday as the wave to the SE shifts
well east over the atlantic. The pressure gradient will ease
though breezy conditions will still occur near the coast. Drier
air will advect into the area with more Sun expected and warming
temperatures. A trough aloft will move across the SE on Thursday
but airmass will be too dry for any precipitation. Slightly below
average temperatures on Wednesday will warm to average march
levels on Thursday.

Long term Friday through Monday Surface high pressure
building in from the north along with a dry NW flow aloft will
result in the dry weather pattern continuing through the weekend.

Surface high will move off the east coast Sunday producing a
return flow which will increase moisture levels and temperatures
early next week. An approaching upper shortwave trough will
produce lift and bring a slight chance of showers on Monday.

Seasonal temperatures expected through the period.

Aviation
Vfr conditions will prevail through at least 13z. Scattered
showers are expected to impact sgj from after 14z through around
20z, with MVFR ceilings expected during this time frame. Periods
of MVFR ceilings and light showers will be possible at the duval
county terminals during the 14z-20z time frame as well. Sustained
north-northeasterly surface winds will strengthen to 10 knots at
sgj and ssi after 10z and will then increase to near 20 knots with
occasional gusts to 30 knots towards 15z. Sustained north-
northeasterly surface winds will increase to near 10 knots at the
duval county terminals by 13z and then 15-20 knots before 16z.

Sustained northeasterly surface winds will increase to 10-15 knots
at gnv after 15z.

Marine
Strong SCA conds develop today with NE winds at 20-25 knots with
occasional gusts to gale force possible and today and tonight with
seas building to 7-10 ft. Winds back to the north on Wednesday and
decrease to 15-20 knots but elevated seas will continue SCA conds.

Winds continue to back to the northwest by Thursday with seas
slowly subsiding through the end of the week.

Rip currents high surf: the onshore flow will promote a high risk
of rip currents today and Wed and surf breakers will slowly build
to 4-6 ft this afternoon and likely into the 5-8 ft range tonight
and will continue into Wednesday and high surf advisory has been
posted.

Coastal flooding: elevated tides up to a foot above normal are
expected with the early morning high tide cycle today, but bigger
surge is expected for this's evening high tide cycle with tidal
departures up to 1-2 ft above predicted levels and have posted
coastal flood advisory for minor flooding during high tide cycles
tonight through both high tide cycles on Wednesday with threat
lessening by Thursday as winds become more offshore.

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.
