Marine Weather and Tides
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.

Short term A pattern change from cool wet and cloudy to warm
dry and sunny will occur in the short term. Sunday night begins
with a seasonably strong weather front pushing north over the gulf
which will introduce gales over the central gulf and near the cape
suckling area. The panhandle as a whole will not see much
precipitation associated with this front with the exception of
yakutat; which may stay wet into Tuesday. Over the northern
panhandle this evening, a chance of rain associated with the
previous front still exists.
Tomorrow a drying trend begins with skies beginning to clear from
south to north as a surface ridge of high pressure establishes
itself over the eastern gulf. This will also act to begin a
significant warm air advection regimen. This new pattern will
bring highs in the upper 60s to the outer coast by Tuesday.
However, further inland temperatures will likely climb into the
70s over the northern panhandle and approach or exceed 80 over
southern panhandle Tuesday.
One limit to the clearing could be a relatively onshore flow
pattern, which may ultimately cause some marine stratus clouds.
If these clouds are able to push inland, temperatures may not
warm as much as anticipated.
Not many changes to the existing forecast were made. Continued the
warming trend over the southern panhandle on Tuesday.
Additionally winds were weakened underneath the surface ridge;
however, where thermally induced winds will likely form, winds
were increased. Primary guidance was a blend of the GFS and
canadian. Forecast confidence is above average in the short term.
Long term Tuesday through Sunday ... As of 9pm Saturday. The
s-swly jet aloft will be pointed at yakutat and the NE gulf coast
on Tuesday, then start to weaken and shift back west for
Wednesday. This will cause rain to gradually decrease, and be
predominantly on the west side of yakutat by Wednesday afternoon.
Otherwise the onshore flow aloft over the rest of the panhandle
will keep some clouds around, but low level flow will be nwly with
the surface ridge axis over the eastern gulf. Expect largely
partly cloudy skies with the best chances for larger breaks on
the lee side of the mountains over the inner channels, ie. Lynn
canal and chatham strait, as well as the southern inner channels.|
Temperatures will be one of the big stories of the week. As of today
temperatures at 850mb are 5-10c from north to south. By Tuesday
afternoon models have these values warming to 16-20c over the
southern panhandle, with the GFS being the coldest and the ecmwf
being the warmest. This would translate to a maximum potential
temperature in the high 80s! Therefore our current forecast in the
mid 70s may end up being on the conservative side. Area rivers will
likely respond to these high temperatures with snow melting at all
A trough (or two) will approach the region from the SW late in
the week and bring the next chance of showers. Models have short
wave troughs passing over at different times however, so there is
some uncertainty. The GFS shows one thurs afternoon (although with
very few showers thanks to the ridge) while the ECMWF and
canadian models don't bring it in until Friday morning. Due to the
variability with location timing from run to run have included a
broader area of slight chance showers for both Thursday and
A low pressure system with a better chance of rain moves into the
gulf from the SW Saturday night, then looks to continue affecting
the region Sunday. The 3 operational long-range models vary the
placement of the low center from the north-central gulf to the se
corner near haida gwaii, with the ECMWF in the middle. The northern
position would give rain to majority of the panhandle while the
southern track would keep the northern third of the panhandle on the
dry side with offshore flow. Both solutions would be wet for the
southern panhandle on Sunday.
Aviation Conditions continue to gradually improve over the
panhandle this Sunday afternoon. However, some areas have been
under persistent ifr conditions. As another front pushes
northward tonight which may bring in lower conditions near yakutat
once again. Conditions are expected to improve tomorrow as the
surface ridge becomes more dominant, but the early hours may be
plagued with low stratus once again.

These are not intended to be fact, they are my opinions. 4) Small programs that generate result presented on a web page. Like any computer program, these may and in some cases do have errors. 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.
