The Flood Watch continues for

* Portions of Central Highlands, Far Eastern, Far Northern, North 
  Woods, and Penobscot Valley Maine., including the following areas, 
  in Central Highlands Maine, Northern Penobscot. In Far Eastern 
  Maine, Southeast Aroostook. In Far Northern Maine, Northeast 
  Aroostook and Northwest Aroostook. In North Woods Maine, Northern 
  Piscataquis and Northern Somerset. In Penobscot Valley Maine, 
  Central Penobscot.

* Through Friday afternoon.

* Snowmelt and the additional rainfall has led to rises on streams 
  and rivers. Rivers and streams will continue to rise over the next 
  18 to  24 hours. Some minor flooding in lowland areas is possible. 
  Ice jams that reside along the Aroostook and Saint John Rivers 
  could break up and move with little notice. This could lead to 
  water backing up behind the jams with the potential of flooding.

  The Mattawamkeag River at Mattawamkeag has been slowly rising and 
  will continue to rise over the next 24 hours. Some minor lowland 
  flooding is possible.

PRECAUTIONARY/PREPAREDNESS ACTIONS...

You should monitor later forecasts and be alert for possible Flood

What forecasters said that day

The local office's own words before this flood watch went out, as it sent them, from the Iowa Environmental Mesonet's archive of National Weather Service text.

NWS Caribou, ME wrote its last area forecast discussion before this flood watch went out at Mar 30, 10:15 AM EDT, 4 hours 54 minutes earlier.

Area forecast discussion, Mar 30, 10:15 AM EDT, 4 hours 54 minutes before
Area Forecast Discussion
National Weather Service Caribou ME
1015 AM EDT Tue Mar 30 2021

.SYNOPSIS...
High pressure will cross the region today, then exit across the
Maritimes tonight into Wednesday. Low pressure will lift north
across the region Wednesday night through Thursday then exit
across the Maritimes Friday. High pressure will build toward the
region from the west Saturday.

&&

.NEAR TERM /THROUGH TONIGHT/...
1015 am update...
Temps are warming rapidly this morning under sunny skies. Mid-
lvl clouds skirting thru the north have had very little impact
on temps. No chgs needed with this update.

Previous Discussion...
Surface high pressure currently off the Mid-Atlantic coast will
move east today, shifting winds out of the south. Satellite
imagery shows a band of mid-level cloud cover moving in from
Quebec today associated with warm advection and overrunning
around and just above 850H. These clouds will move over the area
today, somewhat limiting the full potential for high
temperatures. However, highs will still be well above normal,
ranging from the mid 40s to low 50s. Return flow aloft will
continue to increase overnight as an upper level trough slowly
moves eastward over the Great Lakes. Dew points will rise into
the mid to upper 30s overnight across Downeast Maine, which
will support formation of either a low stratus deck or patchy
fog. This, in turn, should lead to a slight anti-diurnal rise in
temperatures Downeast by daybreak. Lows are expected to remain
above freezing across nearly all of the area.

&&

.SHORT TERM /WEDNESDAY THROUGH THURSDAY NIGHT/...
High pressure will exit across the Maritimes Wednesday. A cold
front will approach from the west later Wednesday, with low
pressure developing along the front across the Mid-Atlantic
region. Clouds increase in advance of the approaching front
Wednesday, with rain chances increasing from the west Wednesday
afternoon. The cold front will begin to slowly cross the region
Wednesday night while low pressure tracks north toward the
region along the front. Rain will occur across the region
Wednesday night. The cold front will slowly begin to cross the
region Thursday while the low moves north along the front.
However, how rapidly this occurs is uncertain. Precipitation
will remain in the form of rain in advance of the front. Colder
air in the wake of the front will allow a transition to a
snow/rain mix or snow. Dependent on the progress of the cold
front, precipitation could transition to a snow/rain mix or snow
across northwest areas Thursday afternoon with some
accumulation possible though amounts remain uncertain. The low
will lift north of Maine Thursday night, drawing the cold front
east of the region. Precipitation will taper to showers in the
wake of the cold front and low. Across northern areas,
precipitation should end in the form of snow or snow showers
with some accumulation possible. Across Downeast areas,
precipitation will taper to snow/rain showers or snow showers.
Temperatures will be at much above normal levels Wednesday.
Temperatures Thursday will be dependent on the location of the
cold front. Temperatures Thursday should generally range from
near normal, to slightly above normal, levels.

&&

.LONG TERM /FRIDAY THROUGH MONDAY/...
An upper low crosses the region Friday, keeping a slight chance
of snow/rain showers across mostly the north and mountains.
Otherwise, expect mostly cloudy/partly sunny skies north with
partly sunny skies Downeast Friday. The upper low moves east
Saturday leaving partly sunny skies across northern areas, with
mostly/partly sunny skies Downeast. A disturbance rotating
around the upper low to the east will cross the region Sunday
with generally partly sunny skies. Could also have a slight
chance of rain/snow showers across mostly the north and
mountains. Upper level troffing could persist across the region
into Monday with generally partly sunny skies across the
forecast area. Near normal, to slightly above normal, level
temperatures are expected Friday/Saturday. Slightly above
normal level temperatures are expected Sunday/Monday.

&&

.AVIATION /14Z TUESDAY THROUGH SATURDAY/...
NEAR TERM: VFR with winds shifting out of the south and gusting
up to 20 knots this afternoon. MVFR/IFR is possible late
tonight Downeast in low stratus and patchy fog. LLWS is expected
tonight.

SHORT TERM:
Wednesday...Variable conditions ranging from VFR to IFR early.
MVFR/IFR late with developing rain. South wind 10 to 15 knots
with gusts up to 20 knots.

Wednesday night...IFR/LIFR with rain. South wind around 10
knots...becoming variable.

Thursday...IFR/LIFR with rain. Possibly mixing with snow
across northwest areas. Uncertainty with wind speed/direction
dependent on the track of low pressure and location of a cold
front.

Thursday night...IFR/LIFR early, MVFR/IFR late. Rain early,
tapering to snow showers north and rain/snow showers Downeast.
Uncertainty with wind speed/direction.

Friday...VFR/MVFR north with a slight chance of snow and rain
showers. Across Downeast areas, VFR/MVFR early then VFR.
Uncertainty with wind speed/direction.

Friday night...VFR/MVFR north, VFR Downeast. Light winds.

Saturday...Occasional MVFR possible early north. Otherwise, VFR.
Light winds.

&&

.MARINE...
NEAR TERM: Winds and seas have briefly decreased below SCA this
morning, but will increase again this afternoon with gusts
around 25 kts and seas of 4 to 6 feet. Patchy fog is possible by
early Wednesday morning.

SHORT TERM: A Small Craft Advisory is in effect through
Wednesday, which will likely need extended Wednesday night
through Thursday night. Patchy fog early Wednesday. Rain and
patchy fog Wednesday night into Thursday night.

.HYDROLOGY...
The Grimes/N Caribou Road near the Caribou-Fort Fairfield town
line remains closed due to water over the road caused by an ice
jam. Water continues to threaten Russell Rd east of the Fort
Fairfield bridge, but no closures at this time. Flows are high,
but it is suspected that ice is anchored in the Fort Fairfield
vicinity keeping the jam in place. Ice movement over the Caribou
Dam will be monitored as this could affect the jam downstream.

Route 164 is also closed in the vicinity of Langille Rd near
Crouseville due to water over the road, likely due to a jam in
Rum Rapids.

Saint John River:
Sheet ice was reported from Van Buren to Keegan, with a ice jam
upstream to around Grand Isle. There is flooding of the typical
lowland areas, with some water/ice approaching Route 1 in spots.
These areas, as well as the open back water near Grand Isle,
will be monitored as temperatures fluctuate this week.

Another significant rain producing system is expected later
Wednesday into Thursday night. Rain from this system, along
with melting snow, will keep elevated river levels along with
the threat of ice jams across northern portions of the region.
