Synopsis for massachusetts and rhode island coastal waters.. Tropical storm jose has stalled well southeast of nantucket and will slowly drift toward the southwest and weaken over the next few days. This will maintain strong winds along with large waves and a chaotic sea. Scattered rain bands will persist, especially across the southern half of the waters. A ridge of high pressure may build over the waters for Sunday and Monday. Hurricane maria may approach the southern waters mid week next week therefore mariners should Monitor the latest forecasts from the national hurricane center at www.nhc.noaa.gov.

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. High pressure
build late Friday into Saturday then remains over the region
into early next week. Hurricane maria is expected to pass
offshore of the east coast and the move farther offshore mid to
late next week as a cold front approaches. The cold front moves
through late Wednesday night into Thursday morning. High
pressure builds in behind the front Thursday. Please refer to
national hurricane center products for more details on jose and
maria.

Near term until 6 am Friday morning
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 tonight, where wind gusts 25-30 mph
are still possible tonight. Cloud shield and some bands of
showers should progress westward into SE ct and eastern long
island where pop has been bumped up to likely. Areas from nws
north west should remain dry.

Lows tonight will range from the lower mid 60s along the coast
and in nyc metro, to 55-60 inland.

A high rip current risk will continue at the ocean beaches into
this evening.

Short term 6 am Friday morning through Friday night
With better daytime mixing winds out east should be a little
stronger, with gusts 30-35 mph through much of the day.

Otherwise sct-numerous morning showers over long island and
southern ct should diminish in coverage through the afternoon.

High temps on Fri should be a little lower than those of today,
ranging from the lower mid 70s across most of ct long island,
to the lower 80s in nyc NE nj.

Skies should gradually clear from west to east Fri night,
becoming mostly clear form nyc north west and ptcldy over
western long island ct, but remaining overcast out east. Lows
fri night should have similar range to those expected for
tonight, from the mid 50s to mid 60s.

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

Long term Saturday through Thursday
Weakening post-tropical jose lingers about 200-300 miles
offshore of montauk Saturday and becomes a remnant low Sunday,
then dissipates. As jose is expected to drift slightly westward
a few showers may brush the far eastern areas, mainly
southeastern connecticut and the twin forks of long island,
Saturday morning. Meanwhile an upper ridge and surface high will
be building into the northeast Saturday and remain across the
region into early next week.

The upper ridge and surface high weaken Tuesday into Wednesday
as a northern stream long wave trough digs into great lakes and
northern plains into Thursday. Meanwhile maria will be moving
offshore of the east coast. There are timing difference with the
timing of a cold front expected to move through Wednesday night
into early Thursday at this time. The upper trough and surface
cold front is expected to move maria farther offshore mid to
late next week. Please refer to national hurricane center
products for more details on maria. Once again there will be
increasing beach hazards with building surf and the possibility
of dangerous rip currents in advance of maria. There is also
uncertainty with how much precipitation will accompany both
maria and the cold front. At this time will be keeping
probabilities at slight chance to low end chance.

Aviation 20z Thursday through Tuesday
Tropical storm 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, with isolated showers possible.

Vfr all terminals. Kgon may be in and out of MVFR tonight.

Gusts generally 20-25 kt, with the highest across the eastern
terminals.

Ny metro enhanced aviation weather support...

Almost all of these also make simplifying assumptions so they are not totally accurate even if there are no errors. Please verify all results. 5) Weather information is from numerious of sources and is presented automatically. 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.
