Discussion
Weather conditions continuing to improve on the northwest arctic
coast this morning. Strong southwest winds are expected to
decrease throughout the day and any residual rain showers along
the north slope will diminish by this afternoon. Southerly flow
will continue through the bering strait, allowing low stratus and
fog along the west coast to linger. Otherwise, quiet weather
conditions in the interior. Temperatures and isolated
thunderstorms will continue to rise as we go through the week,
with Wednesday looking to be the warmest day and largest areal
extent for thunderstorms.

A ridge of high pressure has moved over interior alaska and will
be the dominant feature for the next 24 hours. A longwave trough
situated over siberia will begin to dig into the bering sea today.

This trough will send a shortwave over st. Lawrence island and
through the bering strait tonight. This trough will help to push the
ridge further east and into canada as we go through the week.

Another shortwave will develop tomorrow night and begin to sweep
over the west coast of alaska on Wednesday. A weak upper level low
in the gulf of alaska will send a shortwave over the alaska range
Tuesday and aid in breaking down the ridge. Beyond Wednesday, the
longwave trough will continue to persist in the bering sea, with
model divergence increasing on the intensity and location of the
longwave by Friday morning.

Interior... High pressure in the interior will allow for partly
cloudy to mostly clear skies for the next couple of days.

Temperatures will be trending warmer through Tuesday as high
pressure persists. Smoke has moved into delta junction and has
prompted a dense smoke advisory through noon tomorrow. Smoke is
expected to increase in coverage and intensity in the interior for
the next couple of days. As the high pressure begins to weaken
and move east, isolated thunderstorms expected for Wednesday for
most of the interior. Cooler temperatures and smaller chances for
thunderstorms by the end of the week.

North slope and brooks range... The front that brought rain across
the north slope continues to move north. Showers expected to
taper off along the north slope by this afternoon. Strong
southwesterly flow off the northwest coast continues. Therefore,
elevated surf for CAPE lisburne, point lay, and wainwright is
extended through this afternoon. Winds will be decreasing as the
strong surface low pressure lifts north of wrangel island and
weakens by this afternoon. Temperatures expected to be seasonally
above average for most of the week.

West coast... Strong southwest winds through the bering strait
continues this morning but will begin to weaken today. Elevated
surf for point hope and kivalina and high surf at diomede is
expected through this afternoon. Otherwise, the main weather
concern continues to be low stratus and fog all along the west
coast. These conditions are expected to persist for the next
couple of days. A weather front will push east into st. Lawrence
island, with rain showers likely this evening. The next chance for
precipitation for the west coast will be early Wednesday morning.

Coastal hazard potential days 3 and 4... None.

Fire weather
A warming and drying trend continues for the early part of this
week as high pressure builds into the interior. This will lead to
a noticeable increase in smoke intensity and coverage across the
interior through tomorrow. Isolated thunderstorms for today will
be limited to areas in the alaska range southeast of northway. As
the ridge begins to break down overnight, a thermal trough will
develop over the southern interior tomorrow. Isolated
thunderstorms expected to develop in and along this trough, with
tomorrow and Wednesday being the best days for thunderstorm
activity. Expect gusty winds around showers and thunderstorms
that develop during the afternoon hours. Temperatures begin to
trend down on Wednesday, with thunderstorm potential decreasing
more towards the end of the week for the interior.

Hydrology
Expect glacier-fed rivers to remain elevated through this week due
to increasing temperatures. Otherwise, relatively dry conditions
should keep rivers at their current levels.

Afg watches warnings advisories
High surf advisory for akz213.

Dense smoke advisory for akz223.

Small craft advisory for pkz210-pkz220-pkz225-pkz230.

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.
