* From Monday evening through Wednesday morning

* low pressure will develop off the mid Atlantic coast on Monday
and move northeastward into the Gulf of Maine Tuesday. At this
time it looks as though this low will produce anywhere between 1
to 2.5 inches of rain across much of the area... with locally
higher amounts possible. The heaviest rainfall should occur
Monday night into early Tuesday... but runoff and additional
snowmelt will keep the threat for flooding going through at
least Tuesday night. The heaviest rainfall is expected on the
coastal plain as well as the east slopes of the White Mountains
northeastward into the Maine foothills.

* Rivers are already gradually on the rise from snowmelt over the
past few weeks. 1 to 2.5 inches of rainfall will allow some
rivers to rise to bankfull and even overflow their banks.
Additional ice movement is likely as well. Urban and poor
drainage flooding is also expected... especially Monday night and
the morning hours on Tuesday.

Precautionary/preparedness actions...

A Flood Watch means there is a potential for flooding based on
current forecasts.

You should monitor later forecasts and be alert for possible
flood warnings. Those living in areas prone to flooding should be
prepared to take action should flooding develop.
