When is the rain at its heaviest?

The heaviest rain will fall overnight, roughly between 9 p.m. and 5 a.m. During this timeframe, we expect some torrential downpours and the potential for some flash flooding with rainfall rates as high as 1-to-2 inches per hour.

Several inches of rain (generally 2-3") are expected. Some higher amounts (up to 4") are possible. Hard to pinpoint exactly where the highest amounts will fall, but odds favor southeastern MA and Rhode Island right now.

Flooding concerns and wind

This will undoubtedly lead to widespread urban, street, basement, and small river/stream flooding. Most of the large, mainstem rivers will stay within their banks, however there is concern for renewed flooding for many Rhode Island rivers.

As the storm departs, the winds will increase out of the north-northeast during the day Thursday.

Gusts could top 40 mph over southeastern Massachusetts (especially Cape Cod and the Islands) from Thursday afternoon through the first half of Friday. Across the rest of southern New England, gusts will range between 20-40 mph.
