[Weather] [2023.09.21 PM] NWS Boston EM Briefing: Long Duration Rain Event This Weekend into Early Next Week

[BOX Operations - NOAA Service Account]

Good afternoon,

An area of low pressure over the Carolina coast is forecast to move
northward this weekend and then move offshore early next week. This system
is forecast to bring a period of steady rain to Southern New England this
weekend into early next week.

The greatest impact from this weather system is from heavy rain. We do not
anticipate the torrential kind of rain that was experienced in several
heavy rain events this summer - but rather a long-duration, steady rain
which adds up over time. Even so, as rain falls and adds up, instances of
street flooding as well as rises on mainstem rivers and creeks are still
possible. At this time, we expect rain to fall heavy at times on Saturday,
with a lighter to moderate rain on Sunday and Monday. Exact rain amounts
and how long rain may last are still uncertain and  subject to further
adjustments.

We've attached a one-page briefing, the Excessive Rain Outlook from the
Weather Prediction Center for Saturday, as well as our current best
estimate for rain totals Saturday and Sunday.

Expect the next update to this briefing to be sent by 6 AM Friday.

Thank You!

Meteorologists: Andrew Loconto and Bill Leatham
