Tropical Storm Isaias to bring Maine gusty winds, power outage risk tonight

Isaias is tracking to our west, putting Maine and New Hampshire in line for showers, thunderstorms and gusty winds tonight.

MAINE, USA — Isaias made landfall last night on the North Carolina coast, strengthening just enough to become a category one hurricane.

It's now picking up forward speed and its center will track through western New England tonight. The track of the storm has shifted west a bit - falling on the west side of the cone of uncertainty we were showing over the weekend.

When tropical systems get up into our region, the heaviest rain falls along and west of the storm center. The strongest winds are east of the center, with squally showers and thunderstorms. We will be east of the center tonight, so we'll miss the heaviest rain, but get into some stronger wind gusts.

Tropical Storm Watches and Warnings are in effect, but it's not a big reason to panic. If a tropical system is the cause of strong winds, the National Weather Service issues these advisories instead of the standard high wind ones we are used to hearing about.

The worst will come through overnight tonight.

There will be a lot of clouds today, and the chance for a passing shower or storm during the day. High temperatures will be between 75 and 80 for most.

Isaias' showers and storms move in this evening - with the bulk of the rain and strong winds between 8 p.m. and 2 a.m.

There can be thunder, lightning, heavy rain, and perhaps even a spin-up tornado. There will be tornado watches and warnings to our south, and it's possible that risk extends into Maine later today.

Unfortunately, since the storm has shifted west, we won't get a big drenching that can help ease the drought. The heaviest rain will be in Vermont and New York, with most of us picking up under an inch of water. Downeast Maine won't get much more than a few showers.

The wind gets gusty this evening. The wind gusts will peak in the 45 to 55 mph range, strongest near the coast and in western Maine. I'm only expecting a short period of potential damaging gusts - a few hours centered around midnight. While we should avoid major power outages, scattered ones are expected, so it's better to prepare.

High tide happens around 1 a.m. Some minor splashover and beach erosion is possible during this time, enhanced by the strong onshore wind.

By Wednesday morning, the storm is gone. Wednesday will be partly to mostly sunny, with quick clearing and high temperatures in the 80s.

Follow our updates today and tonight.
