Cooler in Western Washington, Hurricane Henri Approaching New England

The past couple days have been refreshing in Western Washington! Highs have reached the upper 60s to mid 70s, quite nice after many days 80°+.


Cooler weather is expected to continue in Western Washington for the next few days. Below is the Weather Underground forecast for Federal Way.


Sunday and Monday will be in the upper 60s to low 70s, with lows in the upper 40s to low 50s. These will be the “coolest” nights in awhile! Highs increase to the mid-upper 70s on Tuesday and Wednesday, then decrease to the lower 70s on Thursday. Lows remain in the low-mid 50s through at least Thursday.

Important note: A La Niña pattern is currently in the forecast for the Pacific Northwest this winter. This generally means cooler temperatures, more mountain snow, more rain, and a higher possibility of lowland snow. To find out more, check out Cliff Mass’s blog below:

Now to the big weather story in the US…Hurricane Henri (pronounced “ahn-REE”) is moving north toward New England. Below is the Saturday evening satellite image from Tropical Tidbits (Henri in the box).


Below is the official forecast from the National Hurricane Center (NHC) as of 11 PM EDT (8 PM PDT).


A landfall on eastern Long Island is likely on Sunday, with Henri as an 80 mph Category 1 hurricane, the first hurricane to hit New England since Bob in 1991. Henri will begin weakening and move into Connecticut, Rhode Island, and Massachusetts as a tropical storm. 

A big issue along the coastal areas of New England will be storm surge. The NHC surge forecast is below.


Storm surge up to 3-5 feet is forecast from Long Island Sound to Nantucket Island, and beach erosion is possible from New Jersey to Massachusetts. 

Additionally, 2-10 inches of rain will fall in New England as Henri moves through. Flooding is expected.
