A band of slow-moving, drenching rain will cross eastern New England on Tuesday and Tuesday evening, bringing a risk of flooding to Connecticut, Massachusetts, Rhode Island and southern New Hampshire.
Some of the locations most at risk include Boston, Worcester, Brockton, Foxboro, Fitchburg, Lowell, Taunton, Hartford, Danielson and Nashua.
With 10 to as much as 20 inches of snow on the ground in many areas, the danger of flooding will come not only from the rain itself, but also snowmelt.
Recent analysis from a NOAA satellite indicated that, if melted, the snowpack held the equivalent of 1.00-2.00 inches of rain from western and central Massachusetts into southern New Hampshire.
Soaking downpours expected on Tuesday into Tuesday evening will bring up to another inch of rain on top of this, and the result will be rather widespread urban and poor drainage flooding in the I-95 corridor from Providence, R.I. to Portsmouth, N.H.
This will have a large impact on the evening commute as heavy traffic delays are likely.
Additionally, excessive runoff from the rain and melting snow will lead to large standing pools of water in fields and around homes, ranging anywhere from a few inches to a few feet deep in spots.
Areas that don't normally have flooding could briefly be flooded in this type of situation.
There is also potential that some rivers, creeks and streams will go into flood stage during the afternoon and evening hours on Tuesday, especially in the most flood-prone areas. Any flooding of rivers, creeks and streams will be minor, however.
If you can safely do so, remove any snow or ice from drainage areas near your home. If you will be traveling on Tuesday and Tuesday evening, be sure to allow plenty of time to reach your destination. Remember: Never drive around barricades or flooded roadways, as the water may be much deeper than you think.
