[Weather] [2022.04.18 Early PM] NWS Boston EM Briefing UPDATE: Strong Storm to Bring Multiple Weather Hazards Tonight/Tomorrow Morning

[BOX Operations - NOAA Service Account]

Good early afternoon,

We are still reviewing data and incoming forecast guidance, and as such the
forecast is not finalized as yet. However we did want to provide you with
an update regarding the storm system expected to affect Southern New
England later tonight into Tuesday morning.

The forecast regarding strong winds and heavy rain looks to be similar to
what was briefed early this morning. Strong winds and heavy rain appear
likely to pose the greatest overall impact from this storm system.

Regarding the accumulating higher-elevation snow forecast: The storm's
track looks to be adjusting slightly further westward. As this would
translate to a milder overall outcome, we may be looking at lowering snow
amounts slightly for elevations above 1500 ft.

On the coastal flooding forecast: we expect a peak storm surge of around 2
ft to occur Tuesday morning, closer to low tide. At morning high tide, set
to be around 130 AM Tuesday, a surge of 0.5-1 ft is anticipated. This would
mean instances of minor splashover especially from Scituate to the North
Shore. Erosion potential does not look to be a major issue as waves do not
appear to be built up enough around the time of high tide. We are still
considering coastal flood headlines for the Tuesday morning high tide to
address the splashover risk.

Expect a full briefing update with graphics by 500 PM today, shortly after
the forecast is finalized.

Thank You!

Meteorologists: Andrew Loconto, Bill Leatham and Kristie Smith
