Good Afternoon Everyone,

We're sending a quick update to let you know little has changed from this morning's briefing. A complete update will be sent later this afternoon, probably closer to 4 PM.

Here are the key points:

Track/Strength Uncertainty: High
It is unknown how the system will develop and where it will eventually track. This will have a big impact on who sees the heaviest rainfall.

Flash Flooding:

This continues to be our main concern from late Friday into Saturday. The latest information still supports rainfall of 1 to 2 inches on average with locally higher amounts. Minor urban flooding is expected and there is the potential for more significant urban and small stream flooding where the heavier rain falls. Minor rises are expected on the larger rivers but no flooding is forecast at this time.

Severe Weather:

There is the possibility of an isolated tornado Friday night.

Wind:

We are less confident in wind impacts due to high uncertainty as to how the system develops and eventually tracks. It’s quite possible stronger wind gusts (more than 30-40 mph) remain offshore southeast of Cape Cod and the Islands or don’t materialize at all. Prevailing direction of any of the stronger wind gusts should be from the south or southeast.

Seas:

We are also less confident in how much seas will build given uncertainty in the wind forecast. Highest seas approaching 10 feet may affect waters south and east of Cape Cod and the Islands.

Coastal Flooding:

We are highly confident that the threat is low on both coasts as tides are relatively low through the weekend.

Rip Currents:

We have low confidence due to uncertainty in the wind forecast, but there is the potential for moderate rip currents Friday and Saturday, possibly into Sunday, mainly at the south coastal beaches.

If you have any questions or would like more information, don't hesitate to contact us via this email address, on NWSChat, or by phone at 508.622.3280.

Thanks,

Joe DelliCarpini
