QPF/Flash flooding: QPF amounts have increased through the
coastal plain with over 2" possible. With the frozen ground and
small creeks and streams already running high from the last
event expect this will result in some minor flooding through the
coastal plain. With the heaviest rainfall in the 12-18Z time
frame this would be the time for any Flash flooding if the very
high rain rates are able to remain in one spot.
Rivers: Greatest threat for river flooding is across southern
New Hampshire. Here around 2" of QPF is expected in addition to
the melting of the remaining 1-2" of SWE still on the ground
from the prior big snow event. The combination will lead to
minor flooding on several rivers including the Suncook,
Contoocook, Warner, and Piscataquog. This area remains in a
Flood Watch.
