Good morning

Please find attached an updated one page briefing and supporting graphics regarding the ongoing heavy rainfall event.

Significant Changes SInce Last Briefing:

In addition to the areas along and west of I-91, the state of Rhode Island including the Providence area is also expected to experience excessive rainfall with local amounts between 2 and 4 inches possible

Areas of heavy rainfall are expected to continue and expand in coverage across western MA and CT over the next several hours. The excessive rainfall threat for the state of Rhode Island is expected to begin between roughly 8 and 10 am when 1 inch per hour rainfall rates will be possible (see attached animation of 1 inch per hour rainfall rate probabilities). Moderate to heavy rainfall will then expand into eastern MA by late morning/early afternoon and continue into the evening hours.

We continue to anticipate rises along larger rivers and smaller streams this morning into Tuesday. The most significant rises are anticipated in interior western New England, and river levels may remain elevated after cessation of heavy rains. Rivers that are potentially at risk of reaching or exceeding bankfull include the Connecticut, Housatonic, Hoosic, Westfield, Deerfield and Farmington River basins. River Observations and Forecasts can be monitored at the Northeast River Forecast Center webpage linked here: Northeast River Forecast Center
