Update
Early afternoon surface analysis depicts high pressure (1022
millibars) extending down the spine of the appalachian mountains.

Meanwhile, the large eye (40 nautical miles) of major hurricane
maria was located about 1,050 miles to the southeast of mayport,
fl, with the hurricane moving northwestward at 9 mph. Weakening
tropical storm jose was nearly stationary and was centered about
150 miles southeast of CAPE cod. Aloft... A narrow ridge extends
from the lower mississippi valley northeastward into the ohio
valley, while a trough extends southwestward from tropical storm
jose into the coastal carolina region. A weak coastal trough was
generating a few showers over the near shore waters adjacent to
fernandina beach, with a cumulus field building over the coastal
counties as a light onshore wind regime is in the process of
developing. A thin cirrus deck is also streaming northeastward
across our area, with temperatures at noon generally in the mid to
upper 80s, with dewpoints generally in the upper 60s inland and
lower 70s at the coast.

Goes-16 derived total precipitable water vapor imagery indicates a
narrow ribbon of enhanced moisture values (1.8-2.0 inches)
residing along the interstate 10 corridor. We expect isolated
showers to develop along an inland moving atlantic sea breeze
boundary by the mid afternoon hours, generally to the west of
interstate 10. Convection will consolidate somewhat along the i-75
corridor as outflows merge with the big bend sea breeze boundary,
but a lack of forcing aloft should keep coverage scattered for
locations west of waycross and lake city through sunset. Highs
will generally climb to the upper 80s to near 90 inland, with the
sea breeze keeping coastal highs in the mid 80s.

Aviation
Vfr conditions will prevail at the regional terminals. A few
showers could impact gnv after 20z, but confidence remains too low
to include in the tafs at this time. MVFR ceilings may be possible
after 09z tonight at the duval county terminals and sgj, with MVFR
visibilities also possible at gnv and vqq after 08z.

Marine
Onshore winds will develop this afternoon, with long period
east-northeasterly swells originating from jose keeping seas
elevated in the 3-5 foot range offshore. An east-southeasterly
swell originating from hurricane maria will push into the offshore
waters later tonight, building seas into the caution range of 4-6
feet, with 3-5 feet expected near shore. A small craft advisory
for hazardous seas will be required for the offshore waters
beginning on Friday, with seas building to 6-9 feet. Sca
conditions will develop by Friday night in the near shore waters.

Our local pressure gradient will tighten on Saturday as maria
makes its closest approach to our waters (more than 550 miles east
of mayport), with east-northeast winds strengthening to caution
levels of 15-20 knots offshore and just under caution levels near
shore. Offshore seas will peak in the 9-12 foot range on Saturday
night, with near shore seas peaking at 6-9 feet Saturday night and
Sunday. Winds will turn to a more northerly direction and will
decrease by Monday, allowing near shore seas to fall back to
caution levels.

Rip currents: moderate risk today due to lingering long period
east-northeasterly ocean swells originating from tropical storm
jose. High risk expected Friday through Monday as wave heights
build and long period swells originating from hurricane maria
increase.

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.
