New England will see it's first impacts of the 2020 tropical season this week as what is currently Tropical Storm Isaias (pronounced "ees-ah-EE-ahs") moves into New England, although impacts for the Midcoast are expected to be low.

The storm brought wind and rain to the east coast of Florida this weekend fluctuating between a category 1 hurricane down to tropical storm status. The center of the storm is situated off the coast of Georgia and South Carolina as of Monday afternoon with top sustained winds of 70 mph and is forecast to strengthen back to a category 1 hurricane before making landfall along the South Carolina coast Monday night.

The storm will begin to accelerate north and east along the east coast Tuesday reaching southern New England by Tuesday night. The center of the storm will then track through western New England Tuesday night becoming centered over southeast Quebec by Wednesday morning. This will bring soaking rains and a chance of severe thunderstorms  to the region along with brisk winds while building seas off the Maine coast.

A Tropical Storm Warning is current in effect for all of western Maine and the coast as of Tuesday morning. Winds and organized rain will begin to increase later in the day on Tuesday with the bulk of the rain occurring over western Maine and western New England. The dynamic system may result in strong to severe storms with an isolated tornado possible.

Showers and storms will continue Tuesday night then come to an end before sunrise Wednesday with clearing through Wednesday morning. The Midcoast will likely see rainfall totals between 1/2" to 1" with higher amounts west where 1" to 3" of rain will be likely resulting in minor flash flooding.

Winds will become brisk Tuesday night from the south to southeast sustained between 10 to 20 mph with gusts to 40 mph possible, peaking in the early morning hours Wednesday. Seas offshore are expected to build to near 10 feet during this period with up to 5 foot seas for Penobscot Bay, gradually subsiding late Wednesday and into Thursday.

The rapid movement of this system will diminish marine impacts with a reduction of prolonged strong winds through the Gulf of Maine. A deviation further west from the current track will diminish these impacts while a shift east will increase winds and rain for the Midcoast.

A cold front will sweep in behind the storm from the west late Wednesday followed by high pressure for the late week  bringing a noticeable change to the oppressive humidity we saw during the early week along with a slight cool down and mostly sunny conditions.
