Area Forecast Discussion
National Weather Service Caribou ME
1157 AM EDT Sun Mar 15 2026

.WHAT HAS CHANGED...
-Cancelled the Small Craft Advisory over the outer waters.
 Updated the marine discussion.

&&

.KEY MESSAGES...
1) A light wintry mix will occur Monday morning producing a
light glaze of ice. Snow accumulations of up to an inch are also
possible across northern areas, with less than an inch Downeast.
The snow and ice could create hazardous conditions for the
Monday morning commute.

2) A strong storm Monday into Tuesday will bring high winds and
heavy rain, creating potential for scattered power outages and
flooding.

3) Strong winds will generate high seas which could lead to
wave runup and coastal flooding impacts, particularly if timing
lines up with tidal surges.

&&

.DISCUSSION...
KEY MESSAGE 1...
A light wintry mix will occur Monday morning producing a
light glaze of ice. Snow accumulations of up to an inch are also
possible across northern areas, with less than an inch Downeast.
The snow and ice could create hazardous conditions for the
Monday morning commute.

KEY MESSAGE 1 DESCRIPTION...
A warm front will approach late tonight, then lift across the
region Monday. Light overrunning precipitation will develop in
advance of the front during the early morning hours of Monday in
the form of a light wintry mix. The light wintry mix will then
transition to rain, from south to north, through Monday morning.
Before the transition to rain occurs, a glaze of ice is
possible. Snow accumulations of up to an inch are also possible
across northern areas, with less than an inch Downeast. Have
issued Winter Weather Advisories for much of the region, with
the exception of the Downeast coast, Monday morning. The snow
and ice could create hazardous conditions for the Monday
morning commute.

KEY MESSAGE 2...A strong storm Monday into Tuesday will bring
high winds and heavy rain, creating potential for scattered
power outages and flooding.

KEY MESSAGE 2 DESCRIPTION...
Per the previous discussion: A strong occluding low pressure
system will continue to approach from the west on Monday, with
the forecast area in the warm sector Monday into Monday night
prior to a strong frontal passage late Monday night into Tuesday
morning.

Rain:
- Deep moisture will advect into the forecast area on Monday
  with southerly flow and a strengthening LLJ. PWATs could surge
  towards well over 1 inch by Monday night with this event,
  which is 5 standard deviations above normal. To put this
  extreme moisture surge in perspective, the daily record 00z
  March 17 PWAT sample from KCAR is 0.83 inches, with forecast
  PWATs potentially being half an inch of additional moisture
  into a relatively cool air mass. With strong forcing spanning
  from the approaching low pressure system, this will likely
  result in moderate to heavy rainfall across the forecast area,
  with highest precip totals being across the Downeast region,
  where storm total rain amounts could exceed 2 inches.

Hydro:
- Combined with warm temperatures lifting into the 50s through
  this time, the Downeast snow pack will quickly melt. All this
  water and snow melt could result urban and small stream
  flooding, especially Downeast. The snow pack in the north is
  better able to absorb the rain, and expected rain totals are
  less in the northern half of the forecast area. However, rain
  combined with what snow melt does occur in the north could
  also lead to localized ponding. Ice rot is likely in the
  north, while ice movement is quite possible Downeast, such as
  along the Penobscot.

Winds:
- The strong LLJ projected with this system could reach 3 to 4
  standard deviations above normal for 850 mb, and could see
  sustained winds as strong as 70 kts at this level. Rain Monday
  afternoon through Monday night will mix these higher winds
  towards the surface, with gusts reaching 35 to 45 mph. The
  strongest gusts could convectively occur along the FROPA early
  Tuesday morning, with an extra source of forcing and
  tightening of the pressure gradient. Strong southerly winds
  combined with the thawing ground could result in scattered
  power outages.

KEY MESSAGE 3...Strong winds will generate high seas which could
lead to wave runup and coastal flooding impacts, particularly if
timing lines up with tidal surges.

KEY MESSAGE 3 DESCRIPTION...
Models continue to show the LLJ ramping up Monday afternoon and
reaching its peak Monday night. As pressure gradient tightens,
sfc winds range from 30-35 kts Monday afternoon with an increase
in sustained speeds between 35-40kts on Monday night. These
will gradually shift toward the southwest Tuesday morning and
drop back down toward 30kts on Tuesday afternoon.

Storm Surge: The probabilistic storm surge shows the peak
during Monday night towards the early morning hours of Tuesday.
The range of the peak storm surge is between 1.0 to 1.7 ft with
lower amounts during the ramp up and cool down.

Winds: Winds over the waters and long on coast will be from the
SE on Monday during the increasing of the LLJ. The winds will
shift from the S during Monday night during the peak periods.

Waves: During the peak period of Monday night, waves are
expected to reach 12-16 feet along the shoreline with periods of
9-10 seconds.

Tides: High tide times will be around 9:30 am Monday morning,
10 pm Monday night and 10:30 am Tuesday morning. Though the peak
of the storm should be after the 10 pm Monday night high tide,
any shift in storm track will change the timing of the peak of
the storm.

As of this update, the total water levels and wave runup levels
only reach statement criteria. However, this could quickly
change once the peak of the storm approaches high res model
runs.

seas. Rain Monday.

Strong gale conditions are likely Monday night through Tuesday,
with highest winds overnight Monday night that could approach
