Discussion and forecast

Latest advisory brings Tropical Storm Henri just off Nantucket early Monday morning, but note size of potential track area as shown by cone.

Impacts Sun-Mon:

* Damaging winds east of track

* Flooding rain along and west of track

* Storm surge flooding

Cape Cod and the Islands and Southeast Massachusetts will potentially be affected by Tropical Storm Henri. A track just offshore would provide damaging winds, very heavy rain and coastal flooding along eastern and northeastern facing coastal sections. As tides are astronomically high this weekend, some south side surge would occur as well.

Now is the time to plan for these potential impacts. You can find tips at ready.gov/hurricanes
