Synopsis
Tropical storm jose will remain nearly stationary southeast of
long island for the next several days, become post-tropical on
Friday if not sooner, then dissipate this weekend. Meanwhile high
pressure will build to the north this weekend into early next
week. Hurricane maria is then expected to pass east of the
southeast coast and is being monitored closely for any potential
impacts later next week. Please refer to national hurricane center
products for more details on jose and maria.

Near term until 6 pm this evening
High pressure will continue to build in from the north today as
upper ridging is enhanced by deep troughing over the western
states.

Meanwhile TS jose will remain stationary well SE of eastern long
island. The tightest pressure gradient between jose and the
building high will reside across the twin forks of long island
and southeast connecticut today, and this where gusts up to 35
mph will be possible. Cloud shield associated with jose will
continue to bring mostly cloudy skies to at least the eastern
half of the region with a better chance at seeing partly cloudy
skies from the city north and west. Subsidence on the back side
of jose will keep rain bands just to the east of the forecast
area through this evening.

High temperatures will vary, with mid and upper 70s across
eastern ct and long island due to more extensive cloud cover.

Farther west, highs will warm into the lower and mid 80s.

Dangerous rip currents will continue at the ocean beaches
today.

Short term 6 pm this evening through 6 pm Friday
Jose will begin to slowly move westward and weaken late tonight into
Friday as the system gets caught in weak steering flow. The deep
ridging to the west is progged to be highly anomalous so the
westward motion will only bring a weakening jose a bit closer to the
southeast coast of long island. This could bring a few rain bands
back towards the twin forks and southeast connecticut. Have
increased pop to scattered likely coverage for tonight into fri
morning our east. Thickest cloud cover and strongest wind
gusts, 30-35 mph, will continue across eastern sections tonight
into Friday.

Otherwise, upper ridging and high pressure will remain to the north
and west. Dry conditions are forecast for the western two thirds of
the region. Temperatures will be above normal for much of the area,
except for eastern long island and southeast connecticut where highs
on Friday will only reach the upper 60s and lower 70s due to
extensive cloud cover. Elsewhere, highs will reach the upper 70s and
lower 80s.

Dangerous rip currents are likely to continue at atlantic ocean
beaches on Friday.

Long term Friday night through Wednesday
With the weakening post-tropical remnant low of jose lingering
about 200-300 miles offshore of montauk, gusty winds and
showers may still be possible across eastern long island and
connecticut through the weekend. Apart from eastern areas where
clouds may prevail, temperatures will be closer to normal while
humidity will be at comfortable levels as dry air advects
southward around the west side of jose. By early next week, the
system weakens significantly and high pressure settles across
the area, leading to above normal temperatures. Thereafter less
confidence exists in the forecast, as the national hurricane
center has hurricane maria continuing northward off the
southeast coast. Given the forecast path, beach hazards will
likely increase once again with building surf and the
possibility of dangerous rip currents well in advance. What is
less certain is how much precipitation will be possible between
the approaching tropical system and a trough to the west, or how
strong winds will be across the area by mid to late week.

Please continue to monitor national hurricane center forecasts
regarding the track and intensity of maria.

Aviation 18z Thursday through Tuesday
Tropical cyclone jose will meander off the southern new england
coast through Friday. It will push mid and upper level moisture
from east to west across mainly the eastern half of the
terminal area.

Vfr all terminals. Kgon may be in and out of MVFR for a few
hours.

Gusts increase today, generally 20-30 kt, with the highest
across the eastern terminals.

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.
