WHAT HAS CHANGED

-Minor jam remains in place on the Allagash River by the bridge with substantial sheet ice remaining upstream. That is now the only known river ice remaining at this time on northern Maine rivers.

KEY MESSAGES

1) Above normal temperatures through the end of the week combined with some rainfall will continue to melt the remaining snow and ice and clear the northern rives.

DISCUSSION

KEY MESSAGE 1...Above normal temperatures through the end of the week combined with some rainfall will continue to melt the remaining snow and ice and clear the northern rives.

KEY MESSAGE 1 DESCRIPTION... High temperatures through mid-week will range from around 50 in the north to around 60 over some interior southern spots. Highs over the north will continue to be in the upper 50s to near 60 into late week while highs in the south will continue to warm reaching around 60 on Saturday. This will combine with some light rain events Tuesday night and again Thursday night which together may add an additional quarter to a half inch of rainfall across the area. The warm temperatures, moist air, and rain will continue to erode what remains of the snow and ice, as well as the river ice over the north.

River gauges across the north have shown some fluctuations due to ice movement and a minor ice jam has been reported on the Allagash River. Flooding is currently not anticipated. However, we will monitor the fluctuations in river levels and ice movement as the rain, snow melt, and warmer temperatures continue to cause the river ice to break up and erode. It is likely that the most of the northern rivers will be clear by the end of the week with any lingering ice continuing to melt and dissipate over the weekend.

MARINE

Seas will continue to lower this morning to below small craft levels. No headlines are anticipated through Wednesday. Cannot rule out patchy fog and possibly a thunderstorm over the waters this afternoon and evening.

Winds are expected to be below SCA through the coming weekend and seas around 3 ft. Moist air over the colder waters will likely produce some fog and mist over the waters and along the shore with the best chances for fog Wednesday night and again on Friday.
