[Weather] [2025.07.30 PM] NWS Boston/Norton EM Briefing: Heavy Rainfall Threat Thursday PM to Friday AM

[BOX Operations - NOAA Service Account]

Good afternoon,

Attached is our updated one-page briefing highlighting the potential for
flooding across portions of southern New England from Thursday afternoon
through early Friday afternoon.

Since this morning, a *Flood Watch* has been issued for the entire state of
Connecticut from 2 PM Thursday through 2 PM Friday. This watch may be
expanded if confidence increases in higher rainfall totals across
neighboring Massachusetts and/or Rhode Island.

We continue to anticipate widespread rainfall of 1–2 inches, with localized
totals of 3–4 inches possible. Areas receiving 3–4 inches are at the
greatest risk for flooding, particularly the hilly terrain of northern and
western Connecticut. While rises on small streams and creeks to bankfull
are possible, no flooding is anticipated on mainstem rivers.

Drier conditions are expected by Friday afternoon and will continue into
the upcoming weekend.

You can expect your next briefing by *8 AM Thursday*.

Best,
Torry Dooley, Francis Tarasiewicz, Frank Nocera, and Kyle Pederson
