The river continued to slowly rise...cresting slightly over a foot above flood stage...during the afternoon of the 18th. The river then slowly fell...dropping below flood stage during the morning of the 22nd. A portion of the Bancroft Road was closed for several days due to the flooding.
The local office's own words before the first event, 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 the first event at Apr 13, 5:18 AM EST, 3 hours 42 minutes earlier.
Area Forecast Discussion National Weather Service Caribou ME 618 AM EDT Thu Apr 13 2017 .SYNOPSIS... Low pressure will exit across the Canadian Maritimes today. High pressure will build across the region later Friday into Saturday. A warm front will cross the area Saturday night. && .NEAR TERM /THROUGH TONIGHT/... 615am update...Increased pops in the Crown of Maine to reflect the threat of isolated to scattered light sprinkles. Previous discussion... Moist northwesterly flow on the backside of the low will generate widespread cloud cover today. A few sprinkles are possible with the passage of an upper level trough...mostly towards the Crown of Maine. However, with clouds topping out around H800 and likely measurable precip near a trace, opted not to spread high pops across the forecast area. Did increase cloud cover right to the coast for today and also increased high temperatures towards the coast with the offshore flow. Winds will gust towards 20 to 25 mph at times today, but a relatively low mixing height and the clouds should reduce gust potential. Clearing will arrive tonight as drier air advects eastward into the area, but continued breezy conditions should prevent much in the way of a radiation inversion. Did decrease lows in the Allagash below a lot of the guidance as winds often drop off more towards the western border in these synoptic setups. Much drier air arrives later today into tonight with dew points dropping off into the low to mid 20s later tonight. Lows dropping towards the freezing mark or less and these dew points should help slow snow melt and additional river rises. && .SHORT TERM /FRIDAY THROUGH SATURDAY NIGHT/... An upper level trof will exit across the maritimes Friday while surface high pressure builds toward the region. Skies will be partly sunny with the slight chance of an afternoon shower across northern areas Friday, with mostly/partly sunny skies across the remainder of the region. High pressure will cross the region Friday night through early Saturday with mostly clear skies. A warm front will then begin to approach later Saturday which will bring increasing clouds during the afternoon. Low pressure tracking east from the Great Lakes will draw the warm front across the region Saturday night with increasing rain chances. Temperatures will be at near normal levels Friday, with above normal level temperatures Saturday. && .LONG TERM /SUNDAY THROUGH WEDNESDAY/... Low pressure will cross the region Sunday through Sunday night with rain Sunday tapering to rain showers Sunday night. The surface low will exit across the maritimes Monday while an upper trof crosses the region. Expect mostly cloudy skies along with a chance of rain showers across northern areas Monday, with generally partly sunny skies across the remainder of the forecast area. High pressure will cross the region Tuesday with partly/mostly sunny skies. Low pressure could approach from the west later Wednesday with increasing clouds along with a chance of showers. Temperatures are expected to be at above normal levels Sunday. Near normal, to slightly below normal, level temperatures are expected, Monday through Wednesday. && .AVIATION /10Z THURSDAY THROUGH MONDAY/... NEAR TERM: MVFR cigs will affect sites from HUL northward today. Outside of that, VFR is expected. SHORT TERM: Generally expect VFR conditions across the region Friday through Saturday. MVFR/IFR conditions are then expected to develop Saturday night and persist into Sunday. Occasional MVFR conditions could occur across the north and mountains Sunday night, with VFR conditions developing Bangor and Downeast. Occasional MVFR conditions could persist across the north and mountains Monday, with VFR conditions across the remainder of the region. && .MARINE... NEAR TERM: Northwesterly gusts may reach 20 kts, but otherwise no significant weather is expected. Seas will be near 3 feet. SHORT TERM: Conditions are expected to be below small craft advisory levels Friday through much of Saturday, with small craft advisory conditions possibly starting to develop later Saturday. Small craft advisory level conditions are then expected Saturday night. Visibilities will be reduced in developing rain Saturday night. && .HYDROLOGY... Persons with interests along rivers need to remain vigilant and keep a close eye on waterways through the rest of this week. Motorists should pay heed to flooding on roads and not attempt to drive through the potentially swift currents. Have dropped the Flood Watch as no additional rainfall is expected until Saturday night. Much drier and cooler air is arriving and will persist into Saturday night. However, ice jams are still possible. There are existing trouble spots that will have to be monitored today and will be handled with flood advisories or warnings. Ice movement continues on area rivers across northern Maine. We have reports of an ice jam near St. John on the St. John River near Wheelock along Sinclair Brook. It is approx 4-5 miles long but does not appear to be threatening any roadways attm. Open waters exist through Grand Isle with an ice jam near Van Buren towards Hamlin. Latest update from EMA indicates there is still water over Russell Road in Fort Fairfield and on Washburn (route 164) Road due to localized ice jams. DOT has closed Rte 164 near Churchill Brook near Crouseville due to water over entire roadway. An ice jam developed along the Aroostook in Masardis with water within a couple of feet from impacting Garfield Road. Near Island Falls, water rising in the Dyer Brook has prompted closure of the Route 2 bridge until sometime this morning. A point flood warning has been issued on the Mattawamkeag river near the town of Mattawamkeag for river lvls reaching above minor flood this morning and cresting Friday evening, with other rivers along the Penobscot cresting just below minor by this morning. The ice jam on the Pleasant River between Brownville and Milo has not changed much, as no impacts have been reported. && .CAR WATCHES/WARNINGS/ADVISORIES... ME...None.
