Synopsis for the long island waters and new york harbor.. The remnant low of jose will meander and weaken southeast of long island into early next week, as high pressure slowly builds from the west. High pressure over the region weakens Tuesday into Wednesday as a cold front approaches from the west, and hurricane maria is forecast to move to off the carolina coast.

Synopsis
The remnant low of jose will dissipate well to the southeast
over the next couple of days, while high pressure to the
northwest will be in control through the first half of next
week. High pressure over the region weakens Tuesday into
Wednesday as a cold front approaches from the west, and
hurricane maria is forecast by the national hurricane center to
move to off the carolina coast. A cold front will pass through
Wednesday night into Thursday as maria tracks to the northeast.

High pressure builds in from the west Friday. A weak trough of
low pressure may affect the area next Saturday.

Near term until 6 am Sunday morning
Clear tonight with diminishing winds. Could see some river
valley fog late. Lows will range from the lower 70s in nyc, to
the 60s most elsewhere, to the upper 50s in the valleys well
n W of nyc and in the long island pine barrens, per the cooler
of the GFS nam MOS numbers in consideration of
radiational cooling.

Short term 6 am Sunday morning through Sunday night
Expect a continuation of unseasonably warm and dry conditions
as heights aloft continue to rise, with sunny skies. Both mos
guidance and GFS nam mixing up to 857 mb in the afternoon, plus
a 2-3 more degrees, support high temps from the mid 80s to lower
90s, except for the immediate coast where highs will be in the
lower 80s. See climate section for potential records.

Swells from distant hurricane maria will produce a moderate rip
current risk.

Long term Monday through Saturday
The longwave pattern will continue to be highly amplified
Monday with a strong upper ridge over the eastern states, with
a trough across the western states. Dry weather and warm
conditions will remain in place Monday and Tuesday. The eastern
ridge begins to weaken Tuesday into Tuesday night as a shortwave
digs into the northern plains and western great lakes, and
maria moves to east of the carolina coast. This shortwave is not
as amplified as previous forecasts have indicated, however, the
shortwave does move quickly through the northern stream.

Another shortwave does rotate into the long wave trough toward
the end of the week. The upper trough and surface cold front
will lift maria to the northeast and out to sea for the end of
the week. The area will return to more seasonal levels, and
possibly to below normal by next weekend. There is considerable
uncertainty with the second shortwave and a weak surface trough
moving into the ridge. At this time will have slight chance
probabilities for Saturday.

Refer to the latest advisories from the national hurricane center
for the latest forecast information on maria.

Due to long period swells from maria, there will be a prolonged
period of rough surf at the ocean beaches, with the likelihood of a
high risk of rip currents.

Aviation 20z Saturday through Thursday
High pressure builds in from the west through the day on Sunday
as post tropical cyclone jose continues to weaken as it drifts
south and east away from the area.

Vfr through the TAF period.

A few gusts to around 15 kt are possible over the next hour or
so, primarily at kgon. Otherwise, northerly winds will continue
to decrease late this afternoon before becoming light and
variable overnight. Winds then return out of the nne Sunday
morning at 10 kt or less.

Outlook for 18z Sunday through Thursday
Sunday-Monday Vfr.

Monday night-Thursday MVFR or lower possible in scattered
showers.

Marine
Swell of 5 ft at texas tower late this afternoon should be
lowered to 4 ft by opposing offshore flow, so SCA for hazardous
ocean seas still continues until 6 pm west, and until 11 pm from
fire island inlet to moriches inlet. Swells from distant
hurricane maria are unlikely to exceed 5 ft in these areas until
Sunday night. Kept scahs in effect E of moriches inlet, as the
time window seas less than 5 ft appears smaller, and extended
into Monday as these swells build.

Long period swells are expected to remain on the ocean waters
Monday and through the upcoming week. A small craft advisory
will likely be needed through the period.

Winds on the ocean waters remain below small craft advisory
levels until Thursday night when gusts may approach 25 kt on a
northwest flow behind a cold front.

Across the remainder of the waters winds and gusts are expected
to remain below advisory levels Monday through Thursday night.

Hydrology
No hydrologic problems anticipated through the end of next
week.

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.
