Marine Weather and Tides
Hatteras, NC

Version 3.4
What's New / NOTES
5/20/2018 -- NOAA is having problems with the data feed that I use to draw the graphs. They are aware of the issue and working to resolve it. Sometimes changing the location by about a mile will give a correct graph. 3/3/2018 - There is a new GOES Satellite for the east coast that required rewriting that part of the code. Please report any issues.

645 pm edt Thu may 24 2018

Synopsis
The remnants of a stationary front to the south will dissipate
Friday. High pressure will remain over the western atlantic
through next week. Low pressure in the gulf of mexico will move
into the gulf states this weekend and will linger over the
southeast through most of next week.

Near term through tonight
As of 645 pm thu... Latest sfc analysis shows 1021mb high
pressure anchored along the mid-atlantic coast, with weak
stationary boundary over sc. No significant changes needed to
previous forecast for update. Dry conditions expected tonight
with mainly clear skies as high pressure shifts southeast to
become centered over the western atlantic. Lows expected to drop
into the lower 60 inland to mid 60s closer to the coast.

Short term Friday
As of 3 pm thu... Return south to southeast flow will ensue as
sprawling high pressure becomes centered off the southeast
coast. Dry conditions for the most part, with only a slight
chance for an afternoon shower or thunderstorm for the sw
counties as some deeper moisture will be present here.

Otherwise, mostly sunny skies expected.

Long term Friday night through Thursday
As of 3 pm thu... Conditions continued dry and mild Fri night with
lows around 70 most areas. High temps will be in the mid 80s
inland to around 80 near the coast.

Saturday... Continuing moistening and warming conditions
expected, and some indications there will be sct showers around
especially during the morning hours as some weak shortwave
energy swings through. By afternoon, more of a typical summer
time pattern with an iso or sct shower or storm for inland
locales and rising hts.

Sunday... Tricky fcst as some model differences at play. Warm and
humid conditions expected as southerly flow persists. However,
weak ridging will be in place between tropical system in the gom
and bermuda high offshore. The 24 00z GFS is faster with
bringing in surge of tropical moisture through E nc with
widespread covg as early as Sun afternoon, though ecm cmc slower
with ridging continuing through the day. Will blend more heavily
with the drier solns, and continue the inherited chc pops,
though raise them to around 40% inland, as ecm MOS pops
indicate.

Sunday night into Monday... Much better chances for
showers storms arrive this period as a piece of tropical
moisture impacts E nc, indirectly associated with the main
tropical system in the gom. Layer streamlines from the ecmwf
indicate deep moisture convergence over enc maximized late sun
night into mon, and will raise pops to 50-60%. Periods of heavy
rain are possible as mix ratios inc to +14 g kg and pwats AOA 2
inches.

Tuesday into Wednesday... Fcst becomes less certain this period,
as the area will still be under threat for showers and storms
indirectly associated with the tropical system over the deep
south. Will maintain higher chance pops but cap them at 50%, as
timing of potential shortwaves interacting with frontal boundary
in the area will dictate when precip moves through the region.

Nevertheless, it still looks like an unsettled period as very
warm and humid air mass will still be in place. Highs this
period generally in the mid 80s inland to near 80 coast. Lows
will be 70-75.

Aviation 00z Friday through Tuesday
Short term through Friday ...

as of 645 pm thu...VFR with dry conditions expected through the
period. There is the potential for brief shallow MVFR fog early
Friday morning, though think drier air should limit widespread
development... Best chances at oaj iso ewn. Isolated showers
possible for oaj Fri afternoon.

Long term Friday night through Tuesday ...

as of 410 am thu... MainlyVFR through Saturday. Some sct
showers or storms possible on Sat and sun, with much better
chances for showers Sun night into Mon as deep tropical moisture
arrives, and better chances for subVFR conditions developing.

Marine
Short term through Friday ...

as of 645 pm thu... Latest obs show E NE winds 5-15 kt with seas
2-3 ft. No sig changes needed to previous forecast for update. Light
winds and seas in the short term as high pressure just off the
mid- atlantic coast shifts southeast on Friday. Winds will be
easterly tonight, veering to southeast Friday. Speeds will
average only 5-10 knots throughout, with seas on the coastal
waters 2-3 feet.

Long term Friday night through Tuesday ...

as of 410 am thu... Expect E winds at 10-15 knots winds veer to
more SE S by Friday, then inc 15-20 kt on Sat in response to a
re- strengthening of high pressure offshore and increasing
land sea thermal gradient. Fetch of moderately strong southerly
winds increases on Sunday, and in response seas will build to 6+
feet ESP by Sunday night into Monday.

Equipment
As of 630 pm wed... Kmhx radar is down until further notice,
awaiting parts.

Mhx watches warnings advisories
Nc... None.

Marine... None.

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.
