341 pm edt Mon sep 25 2017

Near term through Tuesday
Hurricane maria will continue to move north well away from the
area. Strong subsidence west of the hurricane will keep our area
dry but on the hot side. Daytime temps will be above average.

Tonight will be comfortable with temps near normal.

Short term Tuesday night through Wednesday night
Hurricane maria will move slowly off the coast of north carolina
through Wednesday night. An upper level low will be located over
west central florida Tuesday night. A shortwave will push
southwestward along the atlantic coast of south carolina and
georgia overnight, and then across northeast florida on Wednesday
and Wednesday night. Mainly dry conditions will prevail through
the period. A few showers are possible Wednesday evening across
southeast georgia as moisture and lift increases from the
shortwave. Overnight lows will be in the upper 60s to lower 70s
inland and low to mid 70s coast.

Long term Thursday through Monday
An upper level low over northeastern florida and the northeastern
gulf will remain through Friday, with mainly dry conditions.

Overall pattern begins to change later on Friday as what's left of
maria gets swept eastward into the mean flow over the northern
atlantic, and an upper level trough moves into the eastern great
lakes. This should help force a cold front into the southeast, but
the front may wash out before it gets into southeast georgia.

Either way, breezy east to northeast flow is expected to develop,
bringing back scattered showers and storms this weekend and early
next week. The onshore flow and showers storms will lead to lower
temperatures late this weekend into early next week.

Aviation
Vfr conditions will continue throughout the afternoon and evening
with northerly winds decreasing to near calm during the overnight
hours. ExpectVFR conditions tomorrow morning with light
northwesterly winds slowly increasing into the afternoon.

Marine
Advisory conditions will continue mainly due to seas with swells
from hurricane maria. Advisory conditions will continue longer for
the offshore marine zones as swells keep seas elevated there
until midweek. A weak pressure pattern by late week will mean
light winds and seas for Thursday and Friday. Northeast winds
begin to increase on Saturday.

Rip currents: high rip current risk today due to long period
swells from maria. High surf advisory today for NE florida
beaches due to breakers up to 8 feet.

Hydrology Coastal flood advisory continues through Tuesday for
the st. Johns river basin as onshore winds keep water levels
elevated. Minor flooding with moderate flooding at a few spots
continue at each high tide cycle from jacksonville southward.

Moderate flooding continues along portions of the santa fe river.

Minor flooding still occurring on the satilla river east of
waycross.

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.
