This is the tenth and final spring flood potential outlook of the
2017 season. This outlook is based on current and forecast
hydrometeorological conditions. This includes snow cover and snow
water equivalent, stream and river levels and the amount of ice
coverage, recent precipitation and temperatures, and expected
temperatures and precipitation over the next two weeks.
April precipitation has been above normal. Precipitation totals
within eastern MA and RI ranged from 5.5 to over 8 inches. This was
1.5 to over 3 inches above normal. Across interior Massachusetts and
north central to northeast Connecticut, Precipitation totals
mainly ranged between 4.5 and 7 inches. This was normal to 2
inches above normal.
...Observed snow depths and water equivalents...
As of April 28, no snow remained across southern New England.
...River and Ice Conditions...
As of April 28, rivers and streams in the area were running at
normal to above normal levels. Last night the Pawcatuck River at
Westerly crested just below Flood Stage, due to recent rains and a
boost by the overnight high tide. The river is expected to
gradually recede over the next couple of days.
...Soil Moisture Conditions...
Soil moisture was near normal for this time of year.
...Temperature and Precipitation Outlook...
Over the next 7 days there are chances for additional rainfall.
Scattered showers and isolated thunderstorms cross southern New
England this morning. Scattered showers and isolated thunderstorms
are possible tonight into Saturday ahead of an approaching cold
front. Additional unsettled weather may occur during Sunday into
early next week, associated with an area of low pressure emerging
from the southern Plains States into the Great Lakes Region. The
next chance for a widespread soaking rainfall appears to be
towards the end of the next workweek.
Based on information available at this time, the spring flood
potential is near normal across southern New England.
Rivers and streams were mainly at normal or above normal flows,
and soil moisture is near normal. A lack of snow pack within
southern New England is typical for late-April. There will be
chances for showers over the course of the next week, with the
potential for a more widespread soaking rainfall towards the end of
the next workweek.
Keep in mind that heavy rain can cause flooding any time of the
year. Those with interests along rivers and streams should check the
