WHAT TO KNOW

  • Showers are expected for most of the day today, with overcast skies and temperatures generally in the 60s.
  • Monday through Thursday is mainly dry, but mostly cloudy and cool.
  • A coastal storm will bring a risk of coastal flooding during high tide starting Wednesday through next weekend. Heavy rain and gusty wind is possible but the timing and track of this storm is still uncertain.

Today's Forecast

It's a washout, but flash flooding is not expected. Instead, we'll see steady nuisance rain for most of the day, with about 1 inch expected. Winds will be from the southeast at 10 to 15 mph, and temperatures will be in the 60s, rising to around 70 degrees this evening. A period of heavy rain is possible late this afternoon or early this evening.

Early Work Week

The Monday morning commute will be overcast with an isolated shower, but the rest of the day will be dry with peeks of sunshine. Morning temperatures will be just shy of 60 degrees, with afternoon highs near 70 degrees. It will be cooler than average, but Monday will be the mildest day of the week.
Tuesday and Wednesday are much cooler with mostly cloudy skies and a stray shower possible. Highs are in the low to mid 60s with a strong breeze from the east at 15-20 mph.

Tracking a coastal storm

A coastal storm could develop later this week and bring a stronger east breeze to the area starting on Thursday. We could see minor to moderate coastal flooding during the high-tide time starting Thursday. It's too early to say what, if any impact the storm will have on our area, but there is the potential for it to bring heavy rain and gusty wind to the island as early as Friday or perhaps into next weekend. This storm could remain out to sea, but stay tuned for updates.
