At 1000 PM EDT...A slow-moving upper-low is starting to organize
over the interior Northeast, helping to induce regions of
slow-moving storms over much of northeastern New York and New
England. The surface low pressure system is located over the
southeastern New England coast, with a central pressure of 1006mb
(29.71 in. Hg). The surface cold front extends southward into the
Atlantic Ocean. The heaviest regions of precipitation are
currently located ahead of the front over southeastern Maine, with
a separate maxima over the Adirondack Mountains of Upstate New
York. Some locations over New England have already accumulated
5-10 inches of rain in a short period of time over highly
saturated soils. As a result of the heavy rain, rivers and streams
have risen rapidly, with widespread significant reports of
flooding in towns and roadways. Since Sunday morning, numerous
flash flood warnings have already been issued across much of the
Northeast and New England.
