Weather service warns of minor stream, street flooding as rain drenches area

With warm weather melting last week’s snow and buckets of rain expected to fall, the National Weather Service is warning this morning that some small streams in Massachusetts may see minor flooding.

The forecasters issued flood watches for much of the state. In Central and Eastern Massachusetts, the flood watch is in effect from 2 p.m. today through Wednesday morning. Forecasters said that up to an inch of rain could fall.

Poor drainage street flooding is also likely this afternoon and evening, particularly if snow is blocking storm drains, the forecasters said.

One possible trouble spot: the Assabet River, which forecasters said could rise above flood stage late Wednesday. Other larger streams are expected to rise noticeably but stay within their banks.

The rain is expected to arrive in Southern New England during the morning and afternoon. Highs are expected in the low to mid-50s, forecasters said.

Once a cold front crosses the region and moves off the coast after midnight, the rain will end as lows drop into the lower 30s to the lower 40s.

Skies Wednesday are expected to be partly to mostly sunny, with highs ranging from the mid-40s to the lower 50s, the weather service said.
